Multiband optical variability on diverse timescales of the blazar Ton 599 from 2011 to 2023
O. Vince, C. M. Raiteri, M. Villata +72
(Shortened)Context: We analyze the optical variability of the FSRQ Ton 599 using BVRI photometry from the WEBT collaboration (2011-2023), complemented by photometric and spectrosco…
VHE FSRQs with Fermi-LAT: VHE and even brighter states in high-z FSRQs due to an HBL-like component?
Megha, Pankaj Kushwaha
Very high-energy (VHE) detected flat-spectrum radio quasars (FSRQs) are relatively few despite being the most persistent bright MeV-GeV sources. Focusing on VHE emission, we invest…
Curious Case of CGRaBS J0211+1051: Observational Evidence of Lepto-Hadronic Origin of High-Energy Emission?
Sunil Chandra, Pankaj Kushwaha, Pranjupriya Goswami +1
We present an extensive analysis of the multi-wavelength data of the low-synchrotron-peaked BL Lac object CGRaBS J0211+1051, which has been gathered over more than ten years with m…
Broad-band temporal and spectral study of TeV blazar TXS 0518+211
Avik Kumar Das, Pankaj Kushwaha, Veeresh Singh +3
We present a long-term broad-band temporal and spectral study of a TeV BL Lac source TXS 0518+211 by analyzing nearly 16 years (MJD 54682 -- 60670) of simultaneous optical, UV and…
X-ray variability of VHE detected FSRQs: A comparative study
Lekshmi Dathan, Pankaj Kushwaha
Flat Spectrum Radio Quasars (FSRQs) are weak sources of very high energy (VHE; E>100 GeV) emission, despite exhibiting strong MeV-GeV emissions that dominate their radiative output…
Signature of Seyfert-like component in a blazar 3C 273 and its reflection-based explanation
Haritma Gaur, Main Pal, Muhammad S. Anjum +4
We present the results of blazar 3C 273 obtained from simultaneous observations obtained using XMM-Newton and NuSTAR satellites during the period 2015-2019 in five epochs. When the…
