We present periodicity search analyses on the γ-ray light curve of the TeV blazar PKS 1510-
089 observed by the Fermi Large Area Telescope. We report the detection of two transient …

We present long-term multiwavelength observations of blazar CTA 102 (= 1.037). Detailed
temporal and spectral analyses of γ-ray, X-ray, and UV/optical data observed by Fermi-LAT …

The long term broad-band spectral study of Flat Spectrum Radio Quasars during different
flux states has the potential to infer the emission mechanisms and the cause of spectral …

Blazar jet structure can be indirectly resolved by analyzing the multiwavelength variability. In
this work, we analyze the long-term variability of blazars in radio, optical, and X-ray energies …

In this paper, we present a long-term multiwavelength investigation focusing on 12 distinct
samples of Fermi-4LAC bright flat-spectrum radio quasars (FSRQs). Detailed variability and …

It is well known that the γ-ray emission in blazars originates in the relativistic jet pointed at
the observers. However, it is not clear whether the exact location of the GeV emission is less …

We present a long-term multi-wavelength study of the flat spectrum radio quasar 3C 279
using near simultaneous observations available from July 01, 2012 and June 31, 2018 (MJD …

ABSTRACT OT 081 is a low-synchrotron-peaked (LSP) frequency blazar target, and has
strong emission in the γ-ray band. In July 2016, a significant short-term flare was observed in …

The γ-ray emission from flat-spectrum radio quasars (FSRQs) is thought to be dominated by
the inverse Compton scattering of the external sources of photon fields, eg, accretion disk …

We present a long-term and intraday variability study of optical multiwaveband (UBVRI) data
from the blazar AO 0235+ 164 collected by various telescopes for∼ 44 yr (1975–2019). The …
