Quasar UV/X-ray relation luminosity distances are shorter than reverberation-measured radius-luminosity relation luminosity distances
Narayan Khadka, Michal Zajaček, Raj Prince +5
We use measurements of 59/58 quasars (QSOs), over a redshift range , to do a comparative study of the radius--luminosity () and X-rayUV luminosity…
Dusty plasma in active galactic nuclei
Bożena Czerny, Michal Zajaček, Mohammad-Hassan Naddaf +10
Since many years we know that dust in the form of the dusty-molecular torus is responsible for the obscuration in active galactic nuclei (AGN) at large viewing angles and thus for…
The detection of possible transient Quasi-Periodic Oscillations in the -ray light curve of PKS 0244-470 and 4C+38.41
Avik Kumar Das, Raj Prince, Alok C. Gupta +1
The continuous monitoring capability of Fermi-LAT has enabled the exploration of Quasi-Periodic Oscillations (QPOs) in the -ray light curve of blazar that has given a new perspe…
Accretion disks, quasars and cosmology: meandering towards understanding
Bozena Czerny, Shulei Cao, Vikram Kumar Jaiswal +11
As Setti & Woltjer noted back in 1973, quasars could be used to construct the Hubble diagram but the actual application was not that straightforward. It took years to implement the…
Multiwavelength temporal and spectral study of TeV blazar 1ES 1727+502 during 2014 to 2021
Raj Prince, Rukaiya Khatoon, Pratik Majumdar +2
One of the most important questions in blazar physics is the origin of broadband emission and fast-flux variation. In this work, we studied the broadband temporal and spectral prop…
Modelling time delays from two reprocessors in active galactic nuclei
Vikram Kumar Jaiswal, Raj Prince, Swayamtrupta Panda +1
Context. Continuum time delays from accretion disks in active galactic nuclei (AGN) has been proposed long time ago as a tool for measuring distances to the monitored sources. Howe…
