Red quasars blow out molecular gas from galaxies during the peak of cosmic star formation

HR Stacey, T Costa, JP McKean… - Monthly Notices of …, 2022 - academic.oup.com
Recent studies have suggested that red quasars are a phase in quasar evolution when
feedback from black hole accretion evacuates obscuring gas from the nucleus of the host …

PRUSSIC-I. A JVLA survey of HCN, HCO+, and HNC (1–0) emission in z∼ 3 dusty galaxies: Low dense-gas fractions in high-redshift star-forming galaxies

M Rybak, JA Hodge, TR Greve, D Riechers… - Astronomy & …, 2022 - aanda.org
Dusty star-forming galaxies (DSFGs) at redshift z≥ 1 are among the most vigorously star-
forming galaxies in the Universe. However, their dense (≥ 10 5 cm− 3) gas phase–typically …

Merging rates of compact binaries in galaxies: perspectives for gravitational wave detections

L Boco, A Lapi, S Goswami, F Perrotta… - The Astrophysical …, 2019 - iopscience.iop.org
We investigate the merging rates of compact binaries in galaxies and the related detection
rate of gravitational wave (GW) events with AdvLIGO/Virgo and with the Einstein Telescope …

Dust-enshrouded AGNs Can Dominate Host-galaxy-scale Cold Dust Emission

J McKinney, CC Hayward, LJ Rosenthal… - The Astrophysical …, 2021 - iopscience.iop.org
It is widely assumed that long-wavelength infrared (IR) emission from cold dust (T∼ 20–40
