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 […]
