On the Proper 3D Modeling of Orbits in Wide Binary Gravity Tests
A gravitationally-bound system of wide binary stars with precise 3D relative displacement $\mathbf{r}$ and velocity $\mathbf{v}$ can allow a Keplerian orbit reconstruction for an assumed…UNIONS: Red and blue alignments of DESI DR1 galaxies
Intrinsic alignments (IA) of galaxies are a dominant source of systematics in weak-lensing cosmological analyses, and direct measurements on spectroscopic samples are the primary source of priors on…The IRAC Distant Cluster Survey
We present the Infrared Array Camera (IRAC) Distant Cluster Survey (IDCS), a catalog of 825 galaxy cluster and group candidates identified in the Boötes field using the PZWav detection code.An Empirically Calibrated [C II] Luminosity-Halo Mass Relation for Line Intensity Mapping
Millimeter-wave line intensity mapping aims to observe the high-redshift universe through the 158 $μ$m fine-structure line of [C II], the brightest far-infrared line of star-forming galaxies.The unresolved high-mass frontier of the black hole Fundamental Plane
Accreting black holes follow a Fundamental Plane (FP) linking radio and X-ray luminosities to black hole mass, but whether this relation changes in the ultramassive regime, above…From Dispersion to Metallicity: Probing the Milky Way Circumgalactic Medium with Fast Radio Bursts
Circumgalactic Medium (CGM) plays a critical role in galactic evolution, serving as the primary reservoir for accretion and outflows.The Conditional CMB Visibility of High-Redshift X-Ray Cavities in Galaxy clusters
At high redshift, the cosmic microwave background (CMB) both cools relativistic leptons and provides seed photons for inverse-Compton (IC) X-ray emission.PRISMS GHZ8: Evidence for a Young Burst and Potential Merger Activity at z=10.23
UV-bright galaxies in the early Universe provide important constraints on the rapid build-up of stellar mass and the sources responsible for cosmic reionization.The $δ$ Scuti instability strip and period-luminosity relation as seen by TESS and Gaia DR3
We present an asteroseismic survey of 1,526,218 A- and F-type stars in and around the $δ$ Scuti instability strip using TESS 10-minute cadence data, which resolve the full $δ$ Scuti pulsation…SEAMLESS Survey: A Closer Look at Seven Local Volume Dwarf Galaxies in Diverse Environments
We present Hubble Space Telescope (HST) imaging of six Local Volume dwarf galaxies identified by the SEAMLESS survey - Cetus B, Hydrus A, Ursa Major C, Hydra B, Grapes, and M83-dw14 - along with…Chaos and loss: reevaluating the loss-cone formalism in the context of chaotic diving orbits in flattened potentials
The region close to a massive black hole is one of the few truly spherical geometries in galactic dynamics.When precise inference is wrong: Diagnosing model misspecification with applications to cosmic dawn and reionisation
As observations of the cosmic dawn (CD) and epoch of reionisation (EoR) rapidly improve in precision, the approximate forward models used to interpret them might struggle to keep pace.Bridging Scales: Multi-Zone GRMHD-Informed Anisotropic AGN Feedback in Galaxies
We present a galaxy-scale black hole (BH) accretion and feedback model incorporating results from multi-zone general relativistic magnetohydrodynamic (GRMHD) simulations spanning the event horizon…How to feed your dragon: the role of turbulence in AGN activity
Active galactic nuclei (AGN) are thought to be important drivers of galaxy evolution.Learning Galaxy Kinematics from Spatially Unresolved Spectra
Galaxy kinematics encode information about the assembly histories of galaxies and the black holes at their centers, motivating the measurement of kinematic parameters for large galaxy populations.The assembly of dusty galaxies at $z \geq 4$: grain growth and the evolutionary origin of the dust-to-stellar-mass scatter
Understanding dust evolution is essential for interpreting the properties of galaxies across cosmic time.Kinematic Decomposition of the BCG and ICL in Abell S1063 and MACS J1206
The brightest cluster galaxy (BCG) and the intracluster light (ICL) overlap in space and merge smoothly in surface brightness.NGDEEP: Anchoring the $0.5 < z < 3.5$ Star-Forming Main Sequence at Low Stellar Masses with Ultradeep JWST/NIRISS WFSS
Here we present deep JWST/NIRISS wide-field slitless spectroscopy (WFSS) that covers $\mathrm{Hα}$ and $\mathrm{Hβ}$ for galaxies at $0.5 < z < 3.5$ in the NGDEEP survey.From Quantum Field Fluctuations to High-Redshift AGN: Semiclassical Origins of Halo Mass Function Constraints in the JWST Era
We develop a continuous framework connecting quantum field fluctuations in the early Universe to the abundance and observable properties of galaxies and active galactic nuclei (AGN) at cosmic dawn.FOMO-Z. Optimal galaxy classification, photometric redshifts, and reconstruction of population distributions
We present FOMO-Z (Flexible Optimizer of Multi-dimensional Operators and photo-$z$s), a set of statistical methods implemented in Python for galaxy classification and probabilistic inference from…
