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…
Detection of a Transient Quasi-periodic Oscillation in -Rays from Blazar PKS 2255-282
Ajay Sharma, Anuvab Banerjee, Avik Kumar Das +2
We conducted a comprehensive variability analysis of the blazar PKS 2255-282 using Fermi-LAT observations spanning over four years, from MJD 57783.5 to 59358.5. Our analysis reveal…
Multi-wavelength temporal and spectral study of PKS 0402-362
Avik kumar Das, Sandeep Kumar Mondal, Raj Prince
We study the long-term behavior of the bright gamma-ray blazar PKS 0402-362. Over a span of approximately 12.5 years, from August 2008 to January 2021, we gathered Fermi-LAT tempor…
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…
Gamma-ray flares and broadband spectral study of PKS 0402-362
Avik Kumar Das, Sandeep Kumar Mondal, Raj prince
We study the long-term behavior of the bright gamma-ray blazar PKS 0402-362. We collected approximately 13 years of Fermi-LAT data between Aug 2008 to Jan 2021 and identified three…
Analysis of the intra-night variability of BL Lacertae during its August 2020 flare
Aditi Agarwal, B. Mihov, Vipul Agrawal +7
We present an analysis of the photometry of the blazar BL Lacertae on diverse timescales from mid-July to mid-September 2020. We have used 11 different optical telescopes ar…
The detection of possible transient Quasi-Periodic Oscillations in the -ray light curve of PKS 0244-470 and 4C+38.41
Avik Kumar Das, Raj Prince, Alok C. Gupta +1
The continuous monitoring capability of Fermi-LAT has enabled the exploration of Quasi-Periodic Oscillations (QPOs) in the -ray light curve of blazar that has given a new perspe…
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…
Gamma-Ray Flares in Long Term Light Curve of 3C 454.3
Avik Kumar Das, Raj Prince, Nayantara Gupta
3C 454.3 is frequently observed in flaring state. The long term light curve of this source has been analysed with 9 year (August 2008 - July 2017) data from Fermi LAT detector. We…
