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…
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…
Beyond the 3rd moment: A practical study of using lensing convergence CDFs for cosmology with DES Y3
D. Anbajagane, C. Chang, A. Banerjee +95
Widefield surveys of the sky probe many clustered scalar fields -- such as galaxy counts, lensing potential, gas pressure, etc. -- that are sensitive to different cosmological and…
Probable low-frequency quasi-periodic oscillations in blazars from the ZTF survey
Anuvab Banerjee, Vibhore Negi, Ravi Joshi +6
We investigate the possible presence of quasi-periodic oscillation (QPO) signals in 2103 blazars from the Zwicky Transient Facility (ZTF) time-domain survey. We detect a low-freque…
Broadband Spectro-temporal Study on Blazar TXS 1700+685
Anuvab Banerjee, Prantik Nandi, Raj Prince +2
We attempt to present a multiwavelength variability and correlation study as well as detailed multi-waveband spectral characteristics of the May 2021 -ray flare of the blazar so…
Similarities and Differences in Accretion Flow Properties between GRS 1915+105 and IGR J17091-3624: a Case Study
Anuvab Banerjee, Ayan Bhattacharjee, Dipak Debnath +1
We perform a comparative spectro-temporal analysis on the variability classes of GRS 1915+105 and IGR J17091-3624 to draw inferences regarding the underlying accretion flow mechani…
