A Large Diversity in the Quiescent Fractions of Massive Galaxies in Proto-clusters at $z\sim4-6$ in the FRESCO GOODS fields
To constrain the emergence of the first quiescent galaxies (QGs) and their connection to large-scale structure, we search for rare, high-redshift QGs in proto-clusters using spectral energy…The CGM in a New Light: Emitted H$α$, [NII], and [OIII] around Simulated Dwarf Galaxies
Mapping the circumgalactic medium (CGM) in emission is a critical next step in understanding its role in the baryon cycle and galaxy evolution, and dwarf galaxies ($M_{\star}\lesssim 10^9…The Clouds in the "Middle Ages" I. Star formation history and chemical abundances in the LMC
The LMC is a benchmark galaxy for studying stellar evolution, chemical enrichment, and galaxy interactions due to its proximity and intermediate metallicity.The dearth of dustless HdC stars in the Magellanic Clouds: A metallicity-driven white dwarf merger mass effect
Hydrogen-deficient carbon (HdC) stars are rare supergiants believed to form through the merger of two white dwarfs (WDs).How common are extreme scattering events?: First large sample from the ASKAP VAST survey
Compact radio sources are occasionally observed to undergo extreme scattering events (ESEs): large, chromatic flux-density variations, often by more than a factor of two, over a few months.Neglecting Dynamical Microlensing Can Bias Accretion Disk Size Measurements at the Population Level
Microlensing of strongly lensed quasars probes unresolved accretion disks, but many inference methods use static magnification maps with fixed relative microlens positions.Variable Stars in Local Group Galaxies IX: Tracing the Complex History of NGC 205
We present the most extensive catalogue of variable stars in NGC 205 to date, based on archival HST/ACS imaging of a single field $\sim 4^\prime$ from the galaxy centre (GO-15902)."Helium Enrichment Law": The Relation Between Helium and Metal Enrichment in Stars in FIRE-3 Simulations of Milky Way-mass Galaxies
Helium abundance is a key input to stellar models that are used to infer accurate ages, masses, and compositions for individually resolved stars in the Milky Way (MW), underpinning Galactic…JWST/MIRI Observations of Amorphous Silicates in Interstellar Comet 3I/ATLAS
We present JWST/MIRI Low Resolution Spectroscopy (LRS) of 3I/ATLAS obtained post-perihelion at a heliocentric distance of 2.21 au.Little Red Dots with Broad H$β$ Lines Reveal the Black Hole Mass Function at 7<z<9.5
We present a systematic search for broad H$β$ emission at $7<z<9.5$ in 21,770 JWST/NIRSpec PRISM spectra drawn from four blank fields and six lensing clusters with photometry spanning 1942 arcmin$^2$.The UKIRT M33 Monitoring Project - VII. A 15-year K-band photometric catalogue of long-period variable stars in the central kiloparsec of M33
We present a homogenised K-band photometric catalogue for the central ${\approx}12$ arcmin$^2$ (${\approx}0.9$ kpc$^2$) of the Triangulum spiral galaxy M33, combining four independent PSF-based…The Role of Star Formation and Morphology in the Mass-Metallicity Relation of Galaxies at Cosmic Noon
We investigate the dependence of the mass-metallicity relation (MZR) on star formation and galaxy morphology at 1.7 1000 galaxies.Galactic Dynamics Drives Cyclic Star Formation in Dipole Dwarf Galaxies
Dwarf galaxies are dark matter-dominated systems that are sensitive to feedback and display bursty star formation histories.Weighing dark matter particles with gravitational waves
It is commonly assumed that the mass of dark matter particles cannot be determined from their gravitational effects when dark matter behaves as collisionless matter.What shapes the bright end of the UV luminosity function? Stellar mass, star-formation variability, and dust in JADES
JWST surveys find more UV-bright galaxies at $z>10$ than galaxy-formation models predict, but the roles of recent star formation, stellar mass and dust remain uncertain.Measuring the magnetization profiles of galaxy groups and clusters
Magnetic fields are vital in determining the physical conditions of baryons in massive halos.The Spatially-Resolved Recent Star Formation History of the M81 Disk
The nearby M81 galaxy---a tidally interacting $L^*$ spiral disk---offers a unique perspective on the interplay of secular and external processes in shaping galaxy properties.Identifying Scientifically Interesting Galaxies with Vision-Language Models
Anomaly searches in large astronomical image datasets aim to identify rare objects for follow-up investigation.A GLIMPSE of Dark Matter: JWST Constraints on Early Structure Formation
While we have a solid understanding of how dark matter (DM) behaves during recombination ($z\sim 10^3$) and in the late universe ($z\lesssim$ a few), much less is known about intermediate times…Seeing Unseen Gravitational Wave Inspirals at the Galactic Center
The Galactic Center is expected to host a population of extremely large mass-ratio inspirals (X-MRIs) migrating toward the supermassive black hole.
