Multi wavelength study of 4C+28.07
Avik Kumar Das, Raj Prince, Nayantara Gupta
4C+28.07 is a -ray Flat Spectrum Radio Quasar (FSRQ) type source. It is often monitored at different frequencies, though long-term multi-wavelength data of this source have not…
Broadband Modeling of Low Luminosity Active Galactic Nuclei Detected in Gamma Rays
Gunjan Tomar, Nayantara Gupta, Raj Prince
Low luminosity active galactic nuclei are more abundant and closer to us than the luminous ones but harder to explore as they are faint. We have selected the four sources NGC 315,…
Spectral Modeling of Flares in Long Term Gamma-Ray Light Curve of PKS 0903-57
Sandeep Kumar Mondal, Raj Prince, Nayantara Gupta +1
A detailed study of the BL Lacertae PKS 0903-57 has been done for the first time with 12 years of Fermi Large Area Telescope data. We have identified two bright gamma-ray flares in…
Viewing angle observations and effects of evolution with redshift, black hole mass, and Eddington ratio in quasar based cosmology
Raj Prince, Krzysztof Hryniewicz, Swayamtrupta Panda +2
This study is focused on the observational measurement of the viewing angle of individual quasars by modeling the broadband quasar spectrum ranging from the infra-red (IR) to the s…
Multi-wavelength Analysis and Modeling of OJ 287 During 2017-2020
Raj Prince, Aditi Agarwal, Nayantara Gupta +4
Context. The blazar OJ 287 has been proposed as a binary black hole system based on its periodic optical outburst. Among blazars with parsec scale jets, the black hole binary syste…
A comprehensive study of 2019-2020 flare of OJ 287 using AstroSat, Swift, and NuSTAR
Raj Prince, Gayathri Raman, Rukaiya Khatoon +5
OJ 287 is a well-studied binary black hole system, that occasionally exhibits bright X-ray and optical flares. Here we present a detailed spectral study of its second brightest X-r…
