Cosmic Evolution Survey: LOFAR 144 MHz imaging of the COSMOS field
We present the first deep, targeted LOFAR 144 MHz source catalogue of the COSMOS field, together with the first 144 MHz source counts in this field.The Connection Between the Growth of Massive Black Holes and Their Dynamical Histories
Massive black holes (MBHs) grow through both gas accretion and mergers and it remains unclear how variations to MBH growth and dynamical histories contribute to the spread in empirical scaling…TNGC-SIDM I: Evolution of massive cluster mergers under the self-interacting dark matter paradigm
Merging galaxy clusters provide an ideal laboratory for testing the self-interacting nature of dark matter.How JWST is Revolutionizing Our View of Early Galaxy Formation
The James Webb Space Telescope (JWST) has been revolutionizing our understanding of early galaxy formation over its first four years of science operations.EMRIs in Kerr Spacetime: The Role of Inclination Diffusion
Extreme mass ratio inspirals (EMRIs) are expected to be a major source of gravitational waves (GWs) for the future {\it Laser Interferometer Space Antenna} ({\it LISA}).The Dance of the Little Red Dots: Spectroscopy of Two Blue Companions at z = 3.9 and 5.5 Reveals Young, Metal-Poor Starbursts Merging with Their LRDs within a Few Hundred Myr
The Little Red Dots (LRDs) are compact, red sources, abundant at $4 \lesssim z \lesssim 9$ and likely powered by massive black holes.Wave Cold Dark Matter Can Reproduce the Radial Acceleration Relation in X-ray Elliptical Galaxies
Wave cold dark matter (wave CDM) is a well-motivated variant within the collisionless CDM paradigm, in which the de~Broglie wavelengths of ultralight bosons become relevant on galactic scales.GroArnold: A Framework for Constructing Action-based Models for Triaxial Galaxies and Dark Matter Halos
Action-based distribution functions $f(\mathbf{J})$ provide a powerful description of stellar systems.A Nonlinear General Implicit Runge-Kutta Integrator for Multifluid Charged Dust and Gas
Charged dust in magnetized gas is subject to aerodynamic drag and the Lorentz force, both of which can be difficult to model numerically in a fluid simulation where their characteristic timescales…Substructure-enhanced Collisional Relaxation in Stellar Systems
Two-body collisional relaxation in stellar systems is conventionally estimated using the classical Chandrasekhar theory, in which a subject star is assumed to be embedded in a homogeneous medium of…JWST observations of 47 Tucanae: I. The low-mass main sequence down to the hydrogen-burning limit
We present the first results of a series of studies based on JWST observations of the globular cluster 47 Tucanae (47 Tuc, or NGC 104) obtained with NIRCam.The mass functions of multiple stellar populations in 47 Tucanae
We used a combination of James Webb Space Telescope (JWST) and Hubble Space Telescope (HST) observations to investigate the mass functions (MFs) of the different stellar populations in the globular…The convective-transition gap in 47 Tucanae with JWST
We report the detection of the convective-transition gap along the lower main sequence (MS) of the Galactic globular cluster (GC) 47 Tucanae using deep James Webb Space Telescope (JWST) observations.The connection between massive galaxies and their dark matter haloes from $z=0.25$ to $z \sim 4$ from the combined COSMOS, XMM-LSS and ECDF-S fields
Understanding how galaxies populate and grow within dark matter haloes is essential for linking the observed evolution of galaxies to the hierarchical growth of structure.MOSS III: MeerKATs view on the galaxy populations in two massive galaxy clusters
The MeerKAT Observations of the Saraswati Supercluster (MOSS) is an ongoing project attempting to study the radio and optical properties of the core region of the Saraswati supercluster (z = 0.28)…Are Broad Mg II Galaxies Fading AGN?
We analyzed a sample of 494 galaxies from the Sloan Digital Sky Survey (SDSS) I-IV that have unusual properties.SQuIGGLE: Radio AGN Found Predominantly in Young, Gas-rich Post-starburst Galaxies at z ~ 0.7
The processes that rapidly quench massive galaxies and maintain their quiescence remain poorly understood.Emergence of high-mass stars in complex fiber networks (EMERGE) VII. Multi-Tracer Column Density Synthesis
Obtaining accurate estimates of the gas column density $\mathrm{N(H_2)}$ is crucial to determine the physical conditions of the molecular gas in the Interstellar Medium.Galactic Outflows and Star-Formation Quenching: A JWST Perspective
Outflows driven by active galactic nuclei (AGN) are widely considered a key mechanism for regulating and quenching star formation in massive galaxies.Tracing Accretion and Inner-Disk Gas Evolution in the Orion Nebula via Br-alpha and CO
We present a systematic spectroscopic study of hydrogen Brackett-alpha (Br-alpha) and carbon monoxide (CO) fundamental-band (4.3-5.2 micron) emission from a homogeneous sample of 0.2-1.5 Msun…
