An extended red wing of the 5797 Å diffuse interstellar band in the Red Rectangle nebula
Diffuse interstellar bands (DIBs) are interstellar molecular absorption features that are ubiquitous in the interstellar medium (ISM).QED VI: Neutral hydrogen gas in supernova-driven galactic outflows
Winds that eject mass from galactic discs regulate the growth of galaxies, and observations show that, at least within a few kpc of the disc, most of the mass flux is carried by neutral rather than…Photometric Redshift Estimation with Hybrid Quantum Neural Network
A Hybrid Quantum Neural Network (HQNN) is applied to recover the photometric redshift of a galaxy dataset built using data from two astronomical surveys, the Kilo-Degree Survey (KIDS) and the VISTA…Reconstructing the Three-Dimensional Stellar Mass Profiles of Massive Galaxy Clusters
We investigate the three-dimensional (3D) stellar mass profiles of galaxy clusters using simulations and observations.NOEMA Observations of the Center of M33: A Parsec-scale Molecular Filament and an Ordered Gas-Star-Formation Sequence
We present NOEMA CO(1-0) observations of the inner $\sim$500 pc of M33 at a resolution of $0.91''\times0.37''$ ($3.7\times1.5$ pc), resolving the compact molecular gas structures and revealing their…Inferring the Total Mass of Galaxy Halos Using Photometry
Galaxy size, as defined as the radius at which the stellar surface density reaches $1~\mathrm{M}_\odot\,\mathrm{pc}^{-2}$ ($R_1$), has been shown to correlate more tightly with stellar mass than the…Parameter-Decoupling-Informed Learning for Superresolution: Laboratory Validation and Galaxy Imaging
We present a parameter-decoupling-informed learning model for estimating subwavelength separations of point sources, without requiring prior knowledge of source properties, control over the sources…SPAM: Survey Overview and JWST/NIRCam Multi-Band Photometry Catalog
We present the Star-formation from Photometry through the Addition of Medium-bands (SPAM) survey, a 62.9 hr JWST/NIRCam imaging program to add ten new filters, nine medium-band filters, and one…Constraining Supermassive Black Hole Seeding and Accretion via Occupation Fractions and Mass-Weighted Distributions
The formation of supermassive black holes (SMBHs) is a key open problem in galaxy evolution, with light- and heavy-seeding models predicting distinct black hole occupation fractions (BHOFs).Mapping the Milky Way with SDSS-V: Galactic Genesis Selection Function and Mock Catalog
Robust chemodynamic mapping of the Milky Way requires accounting for the selection function of the survey used, the probability that a given star is included in the final catalog as a function of…Tidal contributions to neutron star orbital precession around Sgr $A^*$
We investigate tidal contributions to the orbital precession of neutron stars around the supermassive black hole Sgr A*, using stellar configurations described by the Tolman - Oppenheimer - Volkoff…The Impact of Flyby Interactions on the Rotation of Open Clusters
The Gaia astrometric mission has provided the first evidence for the bulk rotation of open clusters.Parameter-Decoupled Superresolution with Airy-Disk-Informed Learning: Application to NGC 4486B
Estimating the separation of two unresolved or nearly unresolved sources from recorded intensity images is difficult when source brightness, mutual coherence, and phase are unknown and the…Field-level modeling of halo and galaxy alignments
We develop an effective field theory (EFT) of intrinsic alignments at the level of spin-2 field fluctuations of large-scale structure tracers, such as the shapes of galaxies and dark matter halos.The Stellar Populations of Resolved Galaxies
The study of galaxies outside the Milky Way using observations of resolved stellar populations has experienced extraordinary growth over the past two decades.Detection of star formation in a near-pristine pocket of the Universe
We detect two high-confidence star-forming sources in the environment of a chemically near-pristine ([Fe/H] $<-3.66~;2σ)$ Damped Ly$α$ system (DLA) using Keck/KCWI.What sets the star-formation rate in the Milky Way? I. A multi-scale view of the star-formation rate
The star-formation rate (SFR) is one of the key quantities that characterizes the star formation process and has been extensively investigated both observationally and theoretically.Does the Escape Fraction Prescription Shape Reionization History and Morphology?
The escape fraction of ionizing photons, $f_{\rm esc}$, is one of the least constrained quantities of the Epoch of Reionization (EoR), and the opacity of the intergalactic medium prevents its direct…Dependence of Merger-driven Star Formation and Gas-phase Metallicity Evolution on Merger Type and Stellar Mass
Galaxy mergers play a fundamental role in driving gas inflows, altering star formation, and redistributing metals, yet how these processes depend on merger type, merger stage, and progenitor galaxy…Prospects for Near-Far Constraints on Reionization from Simulated LSST Observations of Milky Way Dwarf Galaxies and Stellar Streams
The NSF-DOE Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST) will detect resolved stellar populations of intact dwarf galaxies and disrupted stellar streams in the Milky Way (MW)…
