Constraining the ratio of median pixel optical depth profile around z ~ 4 quasars using the longitudinal proximity effect
Priyanka Jalan, Hum Chand, Raghunathan Srianand
We present a detailed study of the longitudinal proximity effect using a sample of 85 quasars spanning an emission redshift range of and Lyman continuum…

Gaia GraL: Gaia DR2 Gravitational Lens Systems. V. Doubly-imaged QSOs discovered from entropy and wavelets
A. Krone-Martins, M. J. Graham, D. Stern +22
The discovery of multiply-imaged gravitationally lensed QSOs is fundamental to many astronomical and cosmological studies. However, these objects are rare and challenging to discov…

Probing the environment of high-z quasars using the proximity effect in projected quasar pairs
Priyanka Jalan, Hum Chand, Raghunathan Srianand
We have used spectra of 181 projected quasar pairs at separations arcmins from the Sloan Digital Sky-Survey Data Release 12 in the redshift range of 2.5 to 3.5 to probe t…
