Breaks in the X-ray spectra of high-redshift blazars and the intervening medium

Gaur, Haritma; Mohan, Prashanth; Pandey, Ashwani (IOP Publishing, 2021-06-10)

Flat-spectrum radio quasars (FSRQs) are a subclass of blazars characterized by prominent optical emission lines and a collimated large-scale jet along the observer's line of sight. An X-ray spectral flattening has been ...
Characterizing the Optical Nature of the Blazar S5 1803+784 during Its 2020 Flare

Agarwal, A; Pandey, Ashwani; Ozdonmez, Aykut; Ege, Ergun; Avik, Kumar Das; Volkan, Karakulak (IOP Publishing, 2022-07-01)

We report the results from our study of the blazar S5 1803+784 carried out using quasi-simultaneous B, V, R, and I observations from 2020 May to 2021 July on 122 nights. Our observing campaign detected a historically bright ...
On the Origin of Gamma-Ray Flares from Bright Fermi Blazars

Paliya, Vaidehi S; Böttcher, M; Gurwell, Mark; Stalin, C. S (IOP Publishing, 2021-12)

The origin of γ-ray flares observed from blazars is one of the major mysteries in jet physics. We have attempted to address this problem following a novel spectral energy distribution (SED) fitting technique that explored ...
