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,…

Physical Conditions of Five O VI Absorption Systems Towards PG $1522 + 101$

Sriram Sankar, Anand Narayanan, Blair D Savage +4

We present the analysis of five O VI absorbers identified across a redshift path of z $\sim (0.6 - 1.3)$ towards the background quasar PG $1522 + 101$ with information on five consec…

Solar-Metallicity Gas in the Extended Halo of a Galaxy at $z \sim 0.12$

Jayadev Pradeep, Sriram Sankar, T. M. Umasree +5

We present the detection and analysis of a weak low-ionization absorber at $z = 0.12122$ along the blazar sightline PG~ $1424 + 240$ , using spectroscopic data from both $H S T$ /COS and…
