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…
MCMC-based Voigt Profile fitting to a Mini-BAL System in the Quasar UM675
Dai Ishita, Toru Misawa, Daisuke Itoh +2
We introduce a Bayesian approach coupled with a Markov Chain Monte Carlo (MCMC) method and the maximum likelihood statistic for fitting the profiles of narrow absorption lines (NAL…
Discovery of extremely low-metallicity circumgalactic gas at toward Q0454-220
Jackson M. Norris, Sowgat Muzahid, Jane C. Charlton +3
We have obtained new observations of the absorption system at toward QSO Q0454-220, which we use to constrain its chemical and physical conditions. The system…
The COS-legacy survey of C IV absorbers: properties and origins of the intervening systems
Aditya Manuwal, Anand Narayanan, Purvi Udhwani +4
We present here results from a survey of intervening C IV absorbers at conducted using 223 sightlines from the Hubble Spectroscopic Legacy Archive. Most systems (83%) ou…
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…
