A Multiwavelength Study of a Long-Duration VHE Flare from BL Lacertae with VERITAS
Atreya Acharyya, Avery Archer, Priyadarshini Bangale +72
We report the first observations of a long-duration very-high-energy (VHE; GeV) flare from BL Lacertae (VER J2202+422), taken with the Very Energetic Radiation Imaging Te…
Application of the FRADO model of BLR formation to the Seyfert galaxy NGC 5548 and the first step toward determining the Hubble constant
V. K. Jaiswal, Amit K. Mandal, R. Prince +5
The dynamical and geometric structures of the Broad Line Region (BLR), along with the origins of continuum time delays in active galaxies, remain topics of ongoing debate. In this…
New theoretical Fe II templates for bright quasars
Ashwani Pandey, Mary Loli MartÃnez-Aldama, Bożena Czerny +5
We present a set of new theoretical Fe II templates for bright quasars covering a wavelength range of 1000-10000 Ã \, based on the recent atomic database available in the C23.00 ve…
B2 1308+326: a changing-look blazar or not?
Ashwani Pandey, Chen Hu, Jian-Min Wang +6
In our previous study, we identified a shift in the synchrotron peak frequency of the blazar B2 1308326 from 10 Hz to 10 Hz during a flare, suggesting it could…
Dark and bright sides of the Broad Line Region clouds as seen in the FeII emission of SDSS RM 102
Alberto Floris, Ashwani Pandey, Bozena Czerny +4
Contamination from singly ionized iron emission is one of the greatest obstacles to determining the intensity of emission lines in the UV and optical wavelength ranges. This study…
