Space Mission Options for Reconnaissance and Mitigation of Asteroid 2024 YR4
Brent W. Barbee, Matthew A. Vavrina, Rylie Bull +17
Near-Earth asteroid 2024 YR4 was discovered on 2024-12-27 and its probability of Earth impact in December 2032 peaked at about 3% on 2025-02-18. Additional observations ruled out E…
Modeling the orbital histories of satellites of Milky Way-mass galaxies: testing static host potentials against cosmological simulations
Isaiah B. Santistevan, Andrew Wetzel, Erik Tollerud +3
Understanding the evolution of satellite galaxies of the Milky Way (MW) and M31 requires modeling their orbital histories across cosmic time. Many works that model satellite orbits…
A jolt to the system: ram pressure on low-mass galaxies in simulations of the Local Group
Jenna Samuel, Bhavya Pardasani, Andrew Wetzel +4
Low-mass galaxies are highly susceptible to environmental effects that can efficiently quench star formation. We explore the role of ram pressure in quenching low-mass galaxies ($M…
Streams on FIRE: Populations of Detectable Stellar Streams in the Milky Way and FIRE
Nora Shipp, Nondh Panithanpaisal, Lina Necib +18
We present the first detailed study comparing the populations of stellar streams in cosmological simulations to observed Milky Way dwarf galaxy streams. In particular, we compare s…
Orbital dynamics and histories of satellite galaxies around Milky Way-mass galaxies in the FIRE simulations
Isaiah B. Santistevan, Andrew Wetzel, Erik Tollerud +2
The orbits of satellite galaxies encode rich information about their histories. We investigate the orbital dynamics and histories of satellite galaxies around Milky Way (MW)-mass h…
Extinguishing the FIRE: environmental quenching of satellite galaxies around Milky Way-mass hosts in simulations
Jenna Samuel, Andrew Wetzel, Isaiah Santistevan +5
The star formation and gas content of satellite galaxies around the Milky Way (MW) and Andromeda (M31) are depleted relative to more isolated galaxies in the Local Group (LG) at fi…
The origin of metal-poor stars on prograde disk orbits in FIRE simulations of Milky Way-mass galaxies
Isaiah B. Santistevan, Andrew Wetzel, Robyn E. Sanderson +3
In hierarchical structure formation, metal-poor stars in and around the Milky Way (MW) originate primarily from mergers of lower-mass galaxies. A common expectation is therefore th…
The Formation Times and Building Blocks of Milky Way-mass Galaxies in the FIRE Simulations
Isaiah B. Santistevan, Andrew Wetzel, Kareem El-Badry +5
Surveys of the Milky Way (MW) and M31 enable detailed studies of stellar populations across ages and metallicities, with the goal of reconstructing formation histories across cosmi…
CHANG-ES IV: Radio continuum emission of 35 edge-on galaxies observed with the Karl G. Jansky Very Large Array in D-configuration, Data Release 1
Theresa Wiegert, Judith Irwin, Arpad Miskolczi +21
We present the first part of the observations made for the Continuum Halos in Nearby Galaxies, an EVLA Survey (CHANG-ES) project. The aim of the CHANG-ES project is to study and ch…
