How sky subtraction scales affect Intracluster light measurements
Deep imaging surveys are opening a new window on the low surface brightness universe.CosmoVerse Data Challenge: How Tip of the Red Giant Branch Analysis Choices Shape the Inferred Hubble Constant
Tip of the red giant branch (TRGB)-based determinations of the Hubble constant ($H_0$), the current expansion rate of the Universe, depend on choices made in selecting and analyzing stellar…Searching for Signatures of i-process Nucleosynthesis in Metal-Rich, Lead-rich Barium Stars
The intermediate neutron-capture process ($i$-process) has been invoked to explain the peculiar compositions of carbon-enhanced metal-poor (CEMP) stars enriched in both slow- ($s$) and rapid- ($r$)…Dynamics of self-gravitating halos with decaying dark matter
We study the evolution of self-gravitating spherical dark matter halos composed of dark matter particles that decay to a slightly less massive particle and a massless particle.Euclid. Predicting scaling relations for emission-line galaxies using simulated data
The Euclid spectroscopic surveys will substantially increase the number of observed emission-line galaxies.Euclid: Forecasting the number counts of bright line emitters in the Euclid Wide Survey and Euclid Deep fields
The Euclid mission will revolutionize our understanding of the visible Universe by collecting images and spectra of millions of galaxies across cosmic time and environments.The M87 Black Hole Mass from JWST and Keck Stellar Kinematics Spanning 10 pc to 10 kpc
We combine JWST NIRSpec and Keck KCWI observations to construct a contiguous 2D map of M87's stellar kinematics spanning three decades in projected radius, from ${\sim}10$ pc to ${\sim}10$ kpc, and…A pocket of oxygen in a near-pristine galaxy at z=4.2: chemical inhomogeneity at 10-parsec scales in LAP2
We aim to constrain the oxygen abundance, the ionizing properties, and the spatial structure of LAP2, a strongly lensed (with a magnification $μ$~50) oxygen-deficient galaxy at z=4.2 behind the…She Sees Shells by the Stellar Shore: A Kinematic View of NGC 253's Stellar Halo
The stellar halos of nearby galaxies are fossil records of ancient mergers, providing insight into the formation and growth of these systems.ReveaLLAGN 2: Exploring the Nuclear Gas and Stellar Kinematics of Nearby LLAGNs with JWST/NIRSpec IFU
Low-luminosity active galactic nuclei (LLAGN) represent the most common mode of black hole accretion in the local Universe, yet their nuclear structure, stellar and gas kinematics remain poorly…DESI DR2 Results III: The Mass of the Milky Way
We present measurements of the mass of the Milky Way using distant halo stars selected from the Dark Energy Spectroscopic Instrument (DESI) Data Release 2 (DR2).Mock catalogues for the DESI DR2 Milky Way mass modeling effort
The Dark Energy Spectroscopic Instrument (DESI) survey is an ongoing campaign to obtain millions of spectra, including for stars within the Milky Way.Constraining the Milky Way Mass profile with data driven distribution function using DESI DR2 halo stars
We employ a novel data-driven dynamical modeling method, the empirical distribution function (emPDF), to constrain the Milky Way mass profile using a large sample of halo stars from the Dark Energy…A distribution-function estimate of the Milky Way mass profile from outer halo stars in DESI DR2
We present measurements of the Milky Way mass using blue horizontal-branch (BHB) and RR Lyrae (RRL) stars from the second data release of DESI (DR2), covering its first three years of operations.On the Detectability of Compact Multi-Planet Systems via Gravitational Microlensing
Compact multi-planet systems orbiting ultracool dwarfs, such as TRAPPIST-1, may be a major population of terrestrial worlds with poorly constrained demographics.Identifying Compact Object Candidates using Gaia DR3 Astrometric Accelerations and Jerks
Gaia Data Release 3 (DR3) provides astrometric measurements for more than a billion sources, hundreds of thousands of which have non-single-star astrometric solutions that indicate deviations from…Revisiting the Stellar-Dynamical Mass of the Central Black Hole in NGC 3227
We present a new stellar-dynamical mass for the supermassive black hole in the nearby Seyfert galaxy NGC 3227.The impact of Population III stars on the elemental enrichment of ultra-faint galaxies in the FIRE-3 zoom-in simulations
The observed stellar mass-metallicity relation for ultra-faint galaxies in the Local Group (LG) is in tension with many theoretical predictions, suggesting the need for modified or additional…Harmonic Angular Mapping Method for Binary Microlensing Grid Search
Searching for binary-lens microlensing solutions is computationally demanding because of the complex parameter space and the large number of trial models required.Chemical abundances of a Galactic Centre ejecta discovered in DESI
Chemical abundances in the Galactic Centre (GC) are challenging to measure because of high extinction, crowding, and distance, and are typically limited to the brightest AGB and M giants observed in…
