Gaia-assisted discovery of a detached low-ionisation BAL quasar with very large ejection velocities
J. P. U. Fynbo, P. Møller, K. E. Heintz +10
We report on the discovery of a peculiar Broad Absorption Line (BAL) quasar identified in our Gaia-assisted survey of red quasars. The systemic redshift of this quasar was difficul…
Black hole feedback and the evolution of massive early-type galaxies
Ignacio Martin-Navarro, Joseph N. Burchett, Mar Mezcua
Observationally, constraining the baryonic cycle within massive galaxies has proven to be quite difficult. In particular, the role of black hole feedback in regulating star formati…
Quantifying the effect of black hole feedback from the central galaxy on the satellite populations of groups and clusters
Ignacio Martin-Navarro, Joseph N. Burchett, Mar Mezcua
Super-massive black holes are fundamental ingredients in our theoretical understanding of galaxy formation. They are likely the only sources energetic enough to regulate star forma…
Evolution of the Cool Gas in the Circumgalactic Medium (CGM) of Massive Halos -- A Keck Cosmic Web Imager (KCWI) Survey of Ly Emission around QSOs at
Zheng Cai, Sebastiano Cantalupo, J. Xavier Prochaska +6
Motivated by the recent discovery of the near-ubiquity of Ly emission around QSOs, we performed a systematic study of QSO circumgalactic Ly emission at $z\appro…
Tentative Detection of the Circumgalactic Medium of the Isolated Low-Mass Dwarf Galaxy WLM
Y. Zheng, M. E. Putman, A. Emerick +7
We report a tentative detection of the circumgalactic medium (CGM) of WLM, an isolated, low-mass (log), dwarf irregular galaxy in the Local Group (LG). We an…
The COS Absorption Survey of Baryon Harbors: The Galaxy Database and Cross-Correlation Analysis of OVI Systems
J. Xavier Prochaska, Joseph N. Burchett, Todd M. Tripp +10
We describe the survey for galaxies in the fields surrounding 9 sightlines to far-UV bright, z~1 quasars that define the COS Absorption Survey of Baryon Harbors (CASBaH) program. T…
Feedback from supermassive black holes transforms centrals into passive galaxies by ejecting circumgalactic gas
Benjamin D. Oppenheimer, Jonathan J. Davies, Robert A. Crain +6
Davies et al. (2019) established that for L^* galaxies the fraction of baryons in the circumgalactic medium (CGM) is inversely correlated with the mass of their central supermassiv…
Ultraviolet Signatures of the Multiphase Intracluster and Circumgalactic Media in the RomulusC Simulation
Iryna S. Butsky, Joseph N. Burchett, Daisuke Nagai +3
Quasar absorption-line studies in the ultraviolet (UV) can uniquely probe the nature of the multiphase cool-warm (10^4 < T < 10^6 K) gas in and around galaxy clusters, promising to…
The Panchromatic Circumgalactic Medium
Q. Daniel Wang, Joseph N. Burchett, Nicolas Lehner +7
Galaxies are surrounded by extended atmospheres, which are often called the circumgalactic medium (CGM) and are the least understood part of galactic ecosystems. The CGM serves as…
Following the Metals in the Intergalactic and Circumgalactic Medium over Cosmic Time
Nicolas Lehner, Joseph N. Burchett, J. Christopher Howk +5
The circumgalactic medium (CGM) of galaxies serves as a record of the influences of outflows and accretion that drive the evolution of galaxies. Feedback from star formation drives…
Ultraviolet Perspectives on Diffuse Gas in the Largest Cosmic Structures
Joseph N. Burchett, Daisuke Nagai, Iryna Butsky +31
The past decade has seen an explosion of discoveries and new insights into the diffuse gas within galaxies, galaxy clusters, and the filaments composing the Cosmic Web. A new decad…
Understanding the circumgalactic medium is critical for understanding galaxy evolution
Molly S. Peeples, Peter Behroozi, Rongmon Bordoloi +69
Galaxies evolve under the influence of gas flows between their interstellar medium and their surrounding gaseous halos known as the circumgalactic medium (CGM). The CGM is a major…
