ELVES III: Environmental Quenching by Milky Way-Mass Hosts

Jenny E. Greene, Shany Danieli, Scott Carlsten, Rachael Beaton, Fangzhou Jiang | Summary: [[{“value”:”Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are often devoid of young stars, even in Milky Way-mass groups. Dwarf galaxies thus offer an important laboratory of the environmental processes that cease star formation. We explore the balance […]

ELVES IV: The Satellite Stellar-to-Halo Mass Relation Beyond the Milky-Way

Shany Danieli, Jenny E. Greene, Scott Carlsten, Fangzhou Jiang, Rachael Beaton | Summary: [[{“value”:”Quantifying the connection between galaxies and their host dark matter halos has been key for testing cosmological models on various scales. Below $M_star sim 10^9,M_odot$, such studies have primarily relied on the satellite galaxy population orbiting the Milky Way. Here we present […]

X-ray Emission from the Interstellar and Circumgalactic Medium of Elliptical Galaxies based on MACER simulations

Kavli Affiliate: Feng Yuan | First 5 Authors: Aditi Vijayan, Bocheng Zhu, Miao Li, Feng Yuan, Luis C. Ho | Summary: Interstellar (ISM) and circumgalactic mediums (CGM) around galaxies are linked to several physical processes that drive galaxy evolution. For example, the X-ray emission from the CGM gas around ellipticals has been linked to the […]

Moving gravitational wave sources at cosmological distances: Impact on the measurement of the Hubble constant

Kavli Affiliate: Xian Chen | First 5 Authors: Alejandro Torres-Orjuela, Xian Chen, , , | Summary: Standard sirens — gravitational wave (GW) sources with an electromagnetic (EM) counterpart — can be used to measure the Hubble constant directly which should help to ease the existing Hubble tension. However, if the source is moving, a relativistic […]
