Dusty plasma in active galactic nuclei
Bożena Czerny, Michal Zajaček, Mohammad-Hassan Naddaf +10
Since many years we know that dust in the form of the dusty-molecular torus is responsible for the obscuration in active galactic nuclei (AGN) at large viewing angles and thus for…
Detection of minute-timescale gamma-ray variability in BL Lacertae by Fermi-LAT
Ashwani Pandey, C. S. Stalin
BL Lacertae, the prototype of the BL Lacertae (BL Lac) category of blazars, underwent a giant ray flare in April 2021. The Large Area Telescope (LAT) onboard the Fermi Gamma-ra…
Study of correlation between optical flux and polarization variations in BL Lac objects
Bhoomika Rajput, Ashwani Pandey, C. S. Stalin +1
Polarized radiation from blazars is one key piece of evidence for synchrotron radiation at low energy, which also shows variations. We present here our results on the correlation a…
Characterizing the optical nature of the blazar S5 1803+784 during its 2020 flare
A. Agarwal, Ashwani Pandey, Aykut Özdönmez +3
We report the results from our study of the blazar S5 1803+784 carried out using the quasi-simultaneous , , , and observations from May 2020 to July 2021 on 122 nights…
Variable mass accretion and failed wind explain changing look phenomena in NGC 1365
Santanu Mondal, Tek P. Adhikari, Krzysztof Hryniewicz +2
Changing look active galactic nuclei (CLAGNs) show complex nature in their X-ray spectral shape and line of sight column density variation. The physical mechanisms responsible for…
Intra-night optical variability monitoring of -ray emitting blazars
K. Subbu Ulaganatha Pandian, A. Natarajan, C. S. Stalin +3
We present the results obtained from our campaign to characterize the intra-night-optical variability properties of blazars detected by the {\it Fermi} Large Area Telescope. This i…
