Location of a Sample of GeV and Optical Outbursts in the Jets of Blazars
Maitreya Kundu, Arit Bala, Saugata Barat +1
The exact location of the -ray emitting region in blazar jets has long been a matter of debate. However, the location has important implications about the emission processes, ge…
Sub-Day Timescale X-ray Spectral Variability of the TeV Blazars Mrk 421 and 1ES 1959+650
Susmita Das, Ritaban Chatterjee
We present X-ray spectra ( keV) of two high synchrotron-peaked blazars Mrk 421 and 1ES 1959+650 from simultaneous observations by the SXT and LAXPC instruments onboard \tex…
Accretion Disc-Jet Decomposition from the Optical-Near Infrared Monitoring of Fermi Blazars
Garima Rajguru, Ritaban Chatterjee
We study the variability of the thermal (accretion disc) and non-thermal (jet) emission of thirteen flat spectrum radio quasars in the optical and near infrared (OIR) regime using…
Probing the disc-jet coupling in S4 0954+65, PKS 0903-57, & 4C +01.02 with -rays
Ajay Sharma, Sushanth Reddy Kamaram, Raj Prince +2
We present a comprehensive variability study on three blazars, S4 0954+65, PKS 0903-57, and 4C +01.02 covering a mass range of log(M/M) = 8--9, by using 15 years-lo…
Quasi-periodic oscillation detected in -rays in blazar PKS 0346-27
Raj Prince, Anuvab Banerjee, Ajay Sharma +3
We present a variability study of the blazar PKS 0346-27 from December 2018 to January 2022 in its archival -ray observation by Fermi-LAT. We use the Lomb-Scargle periodogram an…
Correlated Short-Timescale Hard-Soft X-ray Variability of the Blazars Mrk 421 and 1ES 1959+650 using
Susmita Das, Ritaban Chatterjee
We study simultaneous soft ( keV) and hard ( keV) X-ray light curves at a total of eight epochs during of two TeV blazars Mrk 421 and 1ES 1959+650 ob…
