Implications of an updated ultraviolet background for the ionization mechanisms of intervening Ne VIII absorbers
Tanvir Hussain, Vikram Khaire, Raghunathan Srianand +2
Ne VIII absorbers seen in QSO spectra are useful tracers of warm ionized gas, when collisional ionization is the dominant ionization process. While photoionization by the ultraviol…
VoIgt profile Parameter Estimation Routine (VIPER): H I photoionization rate at z<0.5
Prakash Gaikwad, Raghunathan Srianand, Tirthankar Roy Choudhury +1
We have developed a parallel code called "VoIgt profile Parameter Estimation Routine (VIPER)" for automatically fitting the H I Ly- forest seen in the spectra of QSOs. We obtain…
Intergalactic Lyman continuum photon budget in the past 5 billion years
Prakash Gaikwad, Vikram Khaire, Tirthankar Roy Choudhury +1
We constrain the H I photoionization rate at by comparing the flux probability distribution function and power spectrum of the Ly- forest data a…
A Pair of O VI and Broad Ly-alpha Absorbers Probing Warm Gas in a Galaxy Group Environment at z ~ 0.4
Sachin Pachat, Anand Narayanan, Sowgat Muzahid +4
We report on the detection of two O VI absorbers separated in velocity by 710 km/s at z ~ 0.4 towards the background quasar SBS0957+599. Both absorbers are multiphase systems traci…
