Galaxies Below the Fundamental Metallicity Relation Are Morphologically Disturbed: Merian H$α$ Morphologies and DESI Metallicities
Empirical results have revealed a connection between a galaxy's metallicity, mass, and star formation rate, known as the fundamental metallicity relation (FMR), in which metallicity increases with…The universe as a superconductor: How to search for a photon mass
We revisit the bounds on the photon mass when it arises from an Abelian Higgs mechanism rather than a Proca term.Radio Quasars in the Cosmic Dawn: A Spectroscopic Sample from the DESI Survey
We present the largest statistical spectroscopic sample of radio quasars at 4.7<z<6.7 to date.Cavity-driven Gas Transport in Cool-Core Clusters: Implications for Multiphase Gas Cooling
We present a study of gas uplift by cavities and its role in promoting the formation of molecular gas in cool-core galaxy clusters.The birth and fate of stellar clumps in super-early galaxies
(Abridged) JWST has revealed extremely compact stellar clumps in galaxies at z>6, but their formation mechanism and subsequent evolution remain uncertain.N/O-enhanced chemical enrichment by massive stars: the interplay of optically-thick winds and rotation
Recent JWST observations have revealed a sample of high-$z$ galaxies with highly-enhanced N/O abundance ratios, $\log\rm (N/O)\gtrsim -1.1$.The lifetimes and properties of Little Red Dots in the AMBRA simulation
We identify and analyze the little red dots (LRDs) in the AMBRA cosmological hydrodynamic simulation, by producing mock observations of the galaxies and active galactic nuclei (AGN) between…From starlight to dark matter: a stochastic interpolation approach to map dark matter from stellar density
The dark matter halo profile in galaxies holds key information about the nature of dark matter and galaxy formation.Laboratory Evidence that Methanol-Rich Ice Mantles Lower Methyl Formate Binding Energies
Complex organic molecules are widely detected in star-forming regions and are important precursors to prebiotic species.A Multiband Catalog of Infrared-Excess Sources in the Vela-Carina Region: VVVX, DECaPS, and GLIMPSE
Multiwavelength surveys of the Galactic midplane enable the identification of infrared-excess sources, signatures of circumstellar material, though high extinction and crowding hinder detection.In-Situ Star Formation in a Thick Disk: A Model for Metal Enrichment of Mrk 573
Recent observations of the nearby Seyfert galaxy Mrk 573 found that the galactic nucleus and bicone regions surrounding the jet are significantly metal-enriched.Disk truncation triggers relativistic jet launching of a highly accreting supermassive black hole
Relativistic jets are among the most energetic phenomena in the Universe and influence galaxy evolution through energetic feedback, yet the physical connection between accretion flows and jet…CECILIA: Multi-line Constraints on Excess Nebular Emission from Low-Ionization Gas at Cosmic Noon
Spectroscopy from JWST has offered unique insights into elemental abundance patterns at Cosmic Noon (z~2-3), most notably a growing census of sub-solar S/O.The galactic HI-to-halo mass relation from isolated galaxies to cosmological hydrodynamic simulations
The relation between HI and dark matter (DM) halo masses provides key insights into gas accretion and the regulation of galaxy formation.New Optical and Mid-Infrared RR Lyrae Period-Luminosity-Metallicity Relations for Precision Distances and Metallicity Distributions in the Magellanic Clouds
RR Lyrae (RRL) stars, thanks to the existence of their period-luminosity relations, have been widely used as primary standard candles within the Milky Way and the Local Group of galaxies.A High Resolution View of Three Massive Young Stellar Objects in the Magellanic Clouds
The Magellanic Clouds provide an excellent laboratory to study massive star formation beyond typical Galactic environments.Sequential Star-Formation and the Near-Infrared Stellar Populations within N159
We present the first results from a JWST/NIRCam study of the star-forming region N159, one of the richest H II complexes in the Large Magellanic Cloud.Search for High-Ionization Nebular Emission (SHINE). I. A Systematically Selected [Ne V] Sample at z > 3 with JWST/NIRSpec PRISM
We conduct the first systematic Search for High-Ionization Nebular Emission (SHINE) using [Ne V]$\lambda3426$ in JWST/NIRSpec PRISM spectroscopy at $z>3$.Axions and the RR Lyrae Period-Luminosity Relation
We investigate the impact of axions on the period-luminosity relation (PLR) of RR Lyrae stars.The CAMELS-CROCODILE Simulation Suite: A New Cosmology--Astrophysics Playground for Machine Learning
We present CAMELS-CROCODILE, a suite of cosmological hydrodynamic simulations that extends the CAMELS framework with the \gadget{} smoothed particle hydrodynamics code and the Osaka feedback model.
