Properties of Polarized Radio Sources in the Wide Chandra Deep Field South from 2 to 4GHz

Samantha Adams, Mark Lacy, Preshanth Jagannathan +14

We present a study of the linear polarization properties of radio sources within the 10 deg Wide Chandra Deep Field South (W-CDFS) in S-band (2-4 GHz). Our W-CDFS image has an…

Cosmological Simulations of Galaxy Groups and Clusters-III: Constraining Quasar Feedback Models with the Atacama Large Millimeter Array

Avinanda Chakraborty, Suchetana Chatterjee, Mark Lacy +3

The thermal Sunyaev-Zeldovich (SZ) effect serves as a direct potential probe of the energetic outflows from quasars that are responsible for heating the intergalactic medium. In th…

A Candidate Dual QSO at Cosmic Noon

Eilat Glikman, Rachel Langgin, Makoto A. Johnstone +6

We report the discovery of a candidate dual QSO at z=1.889, a redshift that is in the era known as "cosmic noon" where most of the Universe's black hole and stellar mass growth occ…

The Spitzer Extragalactic Representative Volume Survey and DeepDrill extension: clustering of near-infrared galaxies

Eelco van Kampen, Mark Lacy, Duncan Farrah +7

We have measured the angular auto-correlation function of near-infrared galaxies in SERVS+DeepDrill, the Spitzer Extragalactic Representative Volume Survey and its follow-up survey…

The SUPERCOLD-CGM survey: \\ I. Probing the extended CO(4-3) Emission of the Circumglactic medium in a sample of 10 Enormous Ly Nebulae at

Jianrui Li, Bjorn H. C. Emonts, Zheng Cai +10

To understand how massive galaxies at high- co-evolve with enormous reservoirs of halo gas, it is essential to study the coldest phase of the circum-galactic medium (CGM), which…

The Nature of LoBAL QSOs: II. HST/WFC3 Observations Reveal Host Galaxies Dominated by Mergers

Mariana S. Lazarova, Gabriela Canalizo, Mark Lacy +4

Low-ionization Broad Absorption Line QSOs (LoBALs) are suspected to be merging systems in which extreme, AGN-driven outflows have been triggered. Whether or not LoBALs are uniquely…
