The Halo21 Absorption Modeling Challenge: Lessons From "Observing" Synthetic Circumgalactic Absorption Spectra
Zachary Hafen, Sameer, Cameron Hummels +7
In the Halo21 absorption modeling challenge we generated synthetic absorption spectra of the circumgalactic medium (CGM), and attempted to estimate the metallicity, temperature, an…
A Complex Multiphase DLA Associated with a Compact Group at z=2.431 Traces Accretion, Outflows, and Tidal Streams
Nikole M. Nielsen, Glenn G. Kacprzak, Sameer +4
As part of our program to identify host galaxies of known z=2-3 MgII absorbers with the Keck Cosmic Web Imager (KCWI), we discovered a compact group giving rise to a z=2.431 DLA wi…
Probing the physicochemical properties of the Leo Ring and the Leo I group
Sameer, Jane Charlton, Glenn Kacprzak +6
We present an absorption line study of the physical and chemical properties of the Leo HI Ring and the Leo I Group as traced by 11 quasar sightlines spread over a 600 kpc X 800 kpc…
Improving blazar redshift constraints with the edge of the Ly forest: 1ES 1553+113 and implications for observations of the WHIM
J. Dorigo Jones, S. D. Johnson, Sowgat Muzahid +6
Blazars are some of the brightest UV and X-ray sources in the sky and are valuable probes of the elusive warm-hot intergalactic medium (WHIM; K). However, man…
Using cosmological simulations and synthetic absorption spectra to assess the accuracy of observationally derived CGM metallicities
Rachel Marra, Christopher W. Churchill, Caitlin Doughty +6
We used adaptive mesh refinement hydrodynamic cosmological simulations of a Milky Way-type galaxy and a Dwarf galaxy and generated synthetic quasar absorption-line spec…
A partial Lyman limit system tracing intragroup gas at towards HE1003+0149
Anand Narayanan, Sameer, Sowgat Muzahid +6
We present an analysis of the galaxy environment and physical properties of a partial Lyman limit system at z = 0.83718 with HI and metal line components closely separated in redsh…
