Spatial Distribution of OVI Covering Fractions in the Simulated Circumgalactic Medium
Rachel Marra, Christopher W. Churchill, Glenn G. Kacprzak +6
We use adaptive mesh refinement cosmological simulations to study the spatial distribution and covering fraction of OVI absorption in the circumgalactic medium (CGM) as a function…
Cloud-by-cloud, multiphase, Bayesian modeling: Application to four weak, low ionization absorbers
Sameer, J. C. Charlton, J. M. Norris +8
We present a new method aimed at improving the efficiency of component by component ionization modeling of intervening quasar absorption line systems. We carry out cloud-by-cloud,…
Disentangling the multi-phase circumgalactic medium shared between a dwarf and a massive star-forming galaxy at z~0.4
Hasti Nateghi, Glenn G. Kacprzak, Nikole M. Nielsen +4
The multi-phase circumgalactic medium (CGM) arises within the complex environment around a galaxy, or collection of galaxies, and possibly originates from a wide range of physical…
Evidence for galaxy quenching in the green valley caused by a lack of a circumgalactic medium
Glenn G. Kacprzak, Nikole M. Nielsen, Hasti Nateghi +5
The relationship between a galaxy's properties and its circumgalactic medium (CGM) provides a unique view of how galaxies evolve. We present an interesting edge-on (i=86 degrees) d…
MgII Absorbers in High Resolution Quasar Spectra. I. Voigt Profile Models
Christopher W. Churchill, Jessica L. Evans, Bryson Stemock +3
We present the Voigt profile (VP) models, column densities, Doppler b parameters, kinematics, and distribution of components for 422 MgII absorbers found in a survey of 249 HIRES a…
Evolution of CIV Absorbers I. The Cosmic Incidence
Farhanul Hasan, Christopher W. Churchill, Bryson Stemock +7
We present a large high-resolution study of the distribution and evolution of CIV absorbers, including the weakest population with equivalent widths ~Å. By searching 369 h…
Low Mass Group Environments have no Substantial Impact on the Circumgalactic Medium Metallicity
Stephanie K. Pointon, Glenn G. Kacprzak, Nikole M. Nielsen +4
We explore how environment affects the metallicity of the circumgalactic medium (CGM) using 13 low mass galaxy groups (2-5 galaxies) at identified nea…
The CGM at Cosmic Noon with KCWI: Outflows from a Star-forming Galaxy at z=2.071
Nikole M. Nielsen, Glenn G. Kacprzak, Stephanie K. Pointon +3
We present the first results from our CGM at Cosmic Noon with KCWI program to study gas flows in the circumgalactic medium (CGM) at . Combining the power of a high-resolutio…
