Post-starburst galaxies are crucial to disentangling the effect of star formation and quenching on galaxy demographics. They comprise, however, a heterogeneous population of objects, described in numerous ways. To obtain a well-defined and uncontaminated sample, we take advantage of spatially-resolved spectroscopy to construct an unambiguous sample of E+A galaxies - post-starburst systems with no observed ongoing star formation. Using data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) Survey, in the fourth generation of the Sloan Digital Sky Survey (SDSS-IV), we have identified 30 E+A galaxies that lie within the green valley of color–stellar mass space. We first identified E+A candidates by their central, single-fiber spectra and (u-r) color from SDSS DR15, and then further required each galaxy to exhibit E+A properties throughout the entirety of the system to 3 effective radii. We describe our selection criteria in detail, note common pitfalls in E+A identification, and introduce the basic characteristics of the sample. We will use this E+A sample, which has been assembled with stringent criteria and thus re-establishes a well-defined sub-population within the broader category of post-starburst galaxies, to study the evolution of galaxies and their stellar populations in the time just after star formation within them is fully quenched.

The initial conditions found in infrared dark clouds (IRDCs) provide insights on how high-mass stars and stellar clusters form. We have conducted high-angular resolution and high-sensitivity observations toward thirty-nine massive IRDC clumps, which have been mosaicked using the 12 and 7 m arrays from the Atacama Large Millimeter/submillimeter Array. The targets are 70 μm dark massive (220-4900 M _⊙), dense (>10⁴ cm⁻³), and cold (∼10-20 K) clumps located at distances between 2 and 6 kpc. We identify an unprecedented number of 839 cores, with masses between 0.05 and 81 M _⊙ using 1.3 mm dust continuum emission. About 55% of the cores are low-mass (<1 M _⊙), whereas ≲1% (7/839) are high-mass (≳27 M _⊙). We detect no high-mass prestellar cores. The most massive cores (MMC) identified within individual clumps lack sufficient mass to form high-mass stars without additional mass feeding. We find that the mass of the MMCs is correlated with the clump surface density, implying denser clumps produce more massive cores. There is no significant mass segregation except for a few tentative detections. In contrast, most clumps show segregation once the clump density is considered instead of mass. Although the dust continuum emission resolves clumps in a network of filaments, some of which consist of hub-filament systems, the majority of the MMCs are not found in the hubs. Our analysis shows that high-mass cores and MMCs have no preferred location with respect to low-mass cores at the earliest stages of high-mass star formation. © 2023. The Author(s).

When epithelial cell clusters move in a collective manner on a substrate mechanical signals play a major role in organizing the coherent behavior. There are a number of unexplained experimental results from traction force microscopy for a system of this type (MDCK cell clusters). These include: the internal strains are tensile even for clusters that expand by proliferation;the tractions on the substrate are confined to the edges of the cluster;in many cases there are density waves within the cluster;there is collective durotaxis of the cluster even though individual cells show no effect;and for cells in an annulus there is a transition between expanding clusters with proliferation and non-proliferating cases where cells rotate around the annulus. We formulate a simplified mechanical model which explains all of these effects in a straight-forward manner. The central feature of the model is to use a molecular clutch picture which allows "stalling" – inhibition of cell contraction and motility by external forces. Stalled cells are passive elements from a physical point of view and the un-stalled cells are active. When we attach cells to the substrate and to each other, and take into account contact inhibition of locomotion, we get a simple picture that gives all the mechanical results noted above.

Generalized hydrodynamics, quasiparticle diffusion, and anomalous local relaxation in random integrable spin chains

We study the nonequilibrium dynamics of random spin chains that remain integrable (i.e., solvable via Bethe ansatz): because of correlations in the disorder, these systems escape localization and feature ballistically spreading quasiparticles. We derive a generalized hydrodynamic theory for dynamics in such random integrable systems, including diffusive corrections due to disorder, and use it to study nonequilibrium energy and spin transport. We show that diffusive corrections to the ballistic propagation of quasiparticles can arise even in noninteracting settings, in sharp contrast to clean integrable systems. This implies that operator fronts broaden diffusively in random integrable systems. By tuning parameters in the disorder distribution, one can drive this model through an unusual phase transition, between a phase where all wave functions are delocalized and a phase in which low-energy wave functions are quasilocalized (in a sense we specify). Both phases have ballistic transport; however, in the quasilocalized phase, local autocorrelation functions decay with an anomalous power law, and the density of states diverges at low energy.

The delafossite series of layered oxides includes some of the highest conductivity metals ever discovered. Of these, PtCoO2, with a room-temperature resistivity of 1.8 μΩcm for in-plane transport, is the most conducting of all. The high conduction takes place in triangular lattice Pt layers, separated by layers of Co-O octahedra, and the electronic structure is determined by the interplay of the two types of layers. We present a detailed study of quantum oscillations in PtCoO2, at temperatures down to 35 mK and magnetic fields up to 30 T. As for PdCoO2 and PdRhO2, the Fermi surface consists of a single cylinder with mainly Pt character and an effective mass close to the free-electron value. Due to Fermi-surface warping, two close-lying high frequencies are observed. Additionally, a pronounced difference frequency appears. By analyzing the detailed angular dependence of the quantum-oscillation frequencies, we establish the warping parameters of the Fermi surface. We compare these results to the predictions of first-principles electronic-structure calculations including spin-orbit coupling on Pt and Co and on-site correlation U on Co, and hence demonstrate that electronic correlations in the Co-O layers play an important role in determining characteristic features of the electronic structure of PtCoO2.

Metal lead halide perovskite quantum dots (PeQDs) exhibit exceptional optoelectronic properties, showing promise as components for solar cells, lighting, display, and anticounterfeiting devices. However, the instability of PeQDs, along with synthesis and storage methods that rely on hazardous solvents, has limited their potential for commercial applications. To overcome these obstacles, we introduce a solvent-free method for fabricating high-quality green and red CsPbX 3 PeQD (X = Br, I) ink. Using a fluidic system, we first obtained super-high photoluminescence quantum yield PeQDs (92 % for red CsPb(Br,I) 3 , and nearly 100 % for green CsPbBr 3 PeQDs). The uniform nonsolvent PeQD ink is fabricated by modifying the as-formed PeQD surface with a mixture of trimethoxysilane and 3-(trimethoxysilyl)propyl methacrylate silane coupling agents to form PeQDs@silane, then dispersing the PeQDs@silane in a UV-curable 1,6-hexanediol diacrylate monomer. Our solvent-free PeQD ink exhibits bright and stable green and red emissions with long-term stability, retaining 100 % PL intensity after 115 days for CsPbBr 3 and 78 days for CsPb(Br,I) 3 . The environment-friendly ink enables highly uniform and bright films for LED backlighting and patterns for micro-LED applications. With color coordinates near the red and green reference values, the PeQD films demonstrate a remarkable 100.28 % color gamut coverage in comparison with Rec. 2020. This scalable and environmentally friendly method provides a safer alternative than conventional solvent-based PeQD ink.

Quantum criticality in Ising chains with random hyperuniform couplings

We study quantum phase transitions in transverse-field Ising spin chains in which the couplings are random but hyperuniform, in the sense that their large-scale fluctuations are suppressed. We construct a one-parameter family of disorder models in which long-wavelength fluctuations are increasingly suppressed as a parameter α is tuned. For α=0, one recovers the familiar infinite-randomness critical point. For 0<α<1, we find a line of infinite-randomness critical points with continuously varying critical exponents; however, the Griffiths phases that flank the critical point at α=0 are absent at any α>0. When α>1, randomness is a dangerously irrelevant perturbation at the clean Ising critical point, leading to a state we call the critical Ising insulator. In this state, thermodynamics and equilibrium correlation functions behave as in the clean system. However, all finite-energy excitations are localized, thermal transport vanishes, and autocorrelation functions remain finite in the long-time limit. We characterize this line of hyperuniform critical points using a combination of perturbation theory, renormalization-group methods, and exact diagonalization.

We report VLBI monitoring observations of the 22 GHz water (H2O) masers around the Mira variable BX Cam, which were carried out as a part of the EAVN Synthesis of Stellar Maser Animations (ESTEMA) project. Data of 37 epochs in total were obtained from 2018 May to 2021 June with a time interval of 3–4 weeks, spanning approximately three stellar pulsation periods (P =∼440 d). In particular, the dual-beam system equipped on the VERA stations was used to measure the kinematics and parallaxes of the H2O maser features. The measured parallax, π = 1.79 ± 0.08 mas, is consistent with Gaia EDR3 and previously measured VLBI parallaxes within a 1-σ error level. The position of the central star was estimated, based on both the Gaia EDR3 data and the center position of the ring-like 43 GHz silicon-monoxide (SiO) maser distribution imaged with the KVN. The three-dimensional H2O maser kinematics indicates that the circumstellar envelope is expanding at a velocity of 13 ± 4 km s−1, while there are asymmetries in both the spatial and velocity distributions of the maser features. Furthermore, the H2O maser animation achieved by our dense monitoring program manifests the propagation of shock waves in the circumstellar envelope of BX Cam. © 2022, CC BY.

Exposure to Hg in humans is highly neurotoxic. However, Hg biomagnification in marine mammals and predatory fish seems not to affect the species health. Significantly less is known about the response of wild terrestrial species to elevated environmental Hg. Elevated Hg content on par with organ level concentrations in marine mammals has been found in the liver of wild small Indian mongoose. This indicates high levels of exposure and potential biomagnification in analysed animal populations. Synchrotron X-ray fluorescence microscopy revealed significant Hg content in the mongoose brain, where micron-sized Hg-rich deposits were preferentially detected in the cells of the choroid plexus and astrocytes of the subventricular wall. Hg content in these aggregates exhibited significant spatial correlation (r ~ 0.9-0.8) with selenium (Se), suggesting the interaction of two elements. Hg aggregates do not co-localize with lysosomes. The low Hg density inside aggregates indicates diffuse Hg binding to a Se-containing biomolecule rather than much denser HgSe nanoparticles proposed to form in other species. Se K-edge XANES did not match spectra of HgSe material. Our data highlight the susceptibility of small Indian mongoose population to Hg pollution and provide evidence on the adaptation in the form of a Se-based detoxification mechanism sequestering Hg into intracellular aggregates. © 2023, The Authors.

Optical clocks have improved their frequency stability and estimated accuracy1,2,3,4,5,6,7 by more than two orders of magnitude over the best caesium microwave clocks that realise the SI second. Accordingly, an optical redefinition of the second has been widely discussed8,9,10, prompting a need for the consistency of optical clocks to be verified worldwide8,10. While satellite frequency links are sufficient to compare microwave clocks, a suitable method for comparing high-performance optical clocks over intercontinental distances is missing. Furthermore, remote comparisons over frequency links face fractional uncertainties of a few 10−18 due to imprecise knowledge of each clock’s relativistic redshift, which stems from uncertainty in the geopotential determined at each distant location. Here, we report a landmark campaign towards the era of optical clocks, where, for the first time, state-of-the-art transportable optical clocks from Japan and Europe are brought together to demonstrate international comparisons that require neither a high-performance frequency link nor information on the geopotential difference between remote sites. Conversely, the reproducibility of the clocks after being transported between countries was sufficient to determine geopotential height offsets at the level of 4 cm. Our campaign paves the way for redefining the SI second and has a significant impact on various applications, including tests of general relativity11, geodetic sensing for geosciences, precise navigation, and future timing networks.
