The low density and magnetization of a massive galaxy halo exposed by a fast radio burst
J. Xavier Prochaska, Jean-Pierre Macquart, Matthew McQuinn +16
Present-day galaxies are surrounded by cool and enriched halo gas extending to hundreds of kiloparsecs. This halo gas is thought to be the dominant reservoir of material available…
The Mass Inflow and Outflow Rates of the Milky Way
Andrew J. Fox, Philipp Richter, Trisha Ashley +5
We present new calculations of the mass inflow and outflow rates around the Milky Way, derived from a catalog of ultraviolet metal-line high velocity clouds (HVCs). These calculati…
The production and escape of ionizing photons from galaxies over cosmic time (Astro2020 Science White Paper)
Jane R. Rigby, Danielle Berg, Rongmon Bordoloi +10
The ionizing photons produced by massive stars are key actors in galaxy evolution. Ionizing photon production and escape is poorly understood. Improved space-based, spatially-resol…
Obscured AGN at 1.5 < z < 3.0 from the zCOSMOS-deep Survey I. Properties of the emitting gas in the Narrow Line Region
M. Mignoli, A. Feltre, A. Bongiorno +21
We select a sample of 90 obscured (type2) AGN with 1.45<z<3.05 from the zCOSMOS-deep galaxy sample by 5 sigma-detection of the high-ionization CIV λ1549 narrow emission line. The p…
Astro2020 Science White Paper: Spatially Resolved UV Nebular Diagnostics in Star-Forming Galaxies
Bethan James, Danielle Berg, Rongmon Bordoloi +16
Diagnosing the physical and chemical conditions within star-forming galaxies (SFGs) is of paramount importance to understanding key components of galaxy formation and evolution: st…
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…
Spectroscopic Observations of the Fermi Bubbles
Andrew J. Fox, Trisha Ashley, Robert A. Benjamin +9
Two giant plasma lobes, known as the Fermi Bubbles, extend 10 kpc above and below the Galactic Center. Since their discovery in X-rays in 2003 (and in gamma-rays in 2010), the Bubb…
Heavy Element Absorption Systems at : Metal-Poor Neutral Gas and a Diminishing Signature of Highly Ionized Circumgalactic Matter
T. J. Cooper, R. A. Simcoe, K. L. Cooksey +5
Ratios of different ions of the same element encode ionization information independently from relative abundances in quasar absorption line systems, crucial for understanding the m…
