Which Milky Way Streams Make the Best Dark Matter Detectors?
Vedant Chandra, Charlie Conroy, Risa Wechsler +7
The abundance and properties of low-mass dark matter subhalos can be inferred by measuring the density and velocity structure of stellar streams, testing physical models of dark ma…
Classical Cases of Non-solar Mixing Length in Low Mass Stars
Rebecca Woody, Charlie Conroy, Phillip A. Cargile +1
The treatment of convection is one of the largest remaining uncertainties in models of low mass stars. The Mixing Length Theory (MLT) for super-adiabatic convection has come under…
ENhanced Galactic Atmospheres With Arepo: Resolving the CGM at 200 pc with the ENGAWA Simulations
Scott Lucchini, Cecilia Abramson, Cameron Hummels +3
Simulating the small-scale features and dynamics of the circumgalactic medium (CGM) is computationally challenging due to its large volume, low densities, multiphase structure, and…
The Binary Populations of Stellar Streams are Set by Cluster Dynamics
Anya Phillips, Charlie Conroy, Jacob Nibauer +5
We present a suite of direct N-body simulations of low mass () globular cluster streams initialized with observationally-motivated binary demographics in order to…
The Blue Jay Survey: Deep JWST Spectroscopy for a Representative Sample of Galaxies at Cosmic Noon
Sirio Belli, Letizia Bugiani, Minjung Park +17
We present the Blue Jay survey, a cycle 1 JWST program aimed at studying the stellar and gas content of galaxies at cosmic noon. The survey consists of deep spectroscopy for 153 ta…
MESA Isochrones and Stellar Tracks (MIST) III. The White Dwarf Cooling Sequence
Evan B. Bauer, Aaron Dotter, Charlie Conroy +3
We present a substantial update to the MESA Isochrones and Stellar Tracks (MIST) library, extending the MIST model grids and isochrones down the white dwarf (WD) cooling sequence w…
Mapping the Distant and Metal-Poor Milky Way with SDSS-V
Vedant Chandra, Phillip A. Cargile, Alexander P. Ji +28
The fifth-generation Sloan Digital Sky Survey (SDSS-V) is conducting the first all-sky low-resolution spectroscopic survey of the Milky Way's stellar halo. We describe the stellar…
Invisible Accretion: Ionized Envelopes of TNG50 HVCs can Sustain Star Formation
Scott Lucchini, Jiwon Jesse Han, Lars Hernquist +2
Galactic high-velocity clouds (HVCs) are known to be complex, multiphase systems consisting of neutral and/or ionized gas moving at high velocities relative to the rotation of the…
Probing neutral outflows in z ~ 2 galaxies using JWST observations of Ca II H and K absorption lines
Caterina Liboni, Sirio Belli, Letizia Bugiani +12
Using deep JWST/NIRSpec spectra from the Blue Jay survey, we perform the first systematic investigation of neutral gas content in massive galaxies at Cosmic Noon based on the Ca II…
Hypervelocity Stars Trace a Supermassive Black Hole in the Large Magellanic Cloud
Jiwon Jesse Han, Kareem El-Badry, Scott Lucchini +5
Hypervelocity stars (HVSs) are produced by the Hills mechanism when a stellar binary is disrupted by a supermassive black hole (SMBH). The HVS Survey detected 21 unbound B-type mai…
Deriving Stellar Properties, Distances, and Reddenings using Photometry and Astrometry with BRUTUS
Joshua S. Speagle, Catherine Zucker, Angus Beane +18
We present brutus, an open source Python package for quickly deriving stellar properties, distances, and reddenings to stars based on grids of stellar models constrained by photome…
Mapping the Milky Way in 5-D with 170 Million Stars
Joshua S. Speagle, Catherine Zucker, Ana Bonaca +18
We present "augustus", a catalog of distance, extinction, and stellar parameter estimates to 170 million stars from and with dr…
Untangling Magellanic Streams
Dennis Zaritsky, Vedant Chandra, Charlie Conroy +3
The Magellanic Stream (MS) has long been known to contain multiple H I strands and corresponding stellar populations are beginning to be discovered. Combining a sample of 17 stars…
-MC: Self-consistent -enhanced stellar population models covering a wide range of age, metallicity, and wavelength
Minjung Park, Charlie Conroy, Benjamin D. Johnson +3
We present new stellar population models, -MC, self-consistently taking into account non-solar abundances for both isochrones and stellar spectra. The -MC models…
Rising from the Ashes II: The Bar-driven Abundance Bimodality of the Milky Way
Angus Beane, James Johnson, Vadim Semenov +3
The Milky Way hosts at least two modes in its present day distribution of Fe and alpha-elements. The exact cause of this bimodality is disputed, but one class of explanations invol…
From UV-bright Galaxies to Early Disks: the Importance of Turbulent Star Formation in the Early Universe
Vadim A. Semenov, Charlie Conroy, Lars Hernquist
Bursty star formation at early times can explain the surprising abundance of early UV-bright galaxies revealed by JWST but can also be a reason for the delayed formation of galacti…
