Origin of the broadband emission from the transition blazar B2 1308+326
Ashwani Pandey, Pankaj Kushwaha, Paul J. Wiita +3
Transition blazars exhibit a shift from one subclass to the next during different flux states. It is therefore crucial to study them to understand the underlying physics of blazars…
Broad-line region in active galactic nuclei: Dusty or dustless?
Ashwani Pandey, Bozena Czerny, Swayamtrupta Panda +5
Context. Dust in active galactic nuclei is clearly present right outside the broad-line region (BLR) in the form of a dusty molecular torus. However, some models of the BLR predict…
Investigating the origin of optical flares from the TeV blazar S4 0954+65
Ashwani Pandey, Rumen Bachev, Bozena Czerny +4
Aims. We aim to investigate the extreme variability properties of the TeV blazar S4 0954+65 using optical photometric and polarisation observations carried out between 2017 and 202…
UV Fe II emission model of HE 0413-4031 and its relation to broad-line time delays
Michal Zajaček, Swayamtrupta Panda, Ashwani Pandey +11
Fe II emission is a well-known contributor to the UV spectra of active galactic nuclei and the modeling of this part may affect the results obtained for the MgII emiss…
Wavelength-resolved reverberation mapping of intermediate redshift quasars HE 0413-4031 and HE 0435-4312: Dissecting Mg II, optical Fe II, and UV Fe II emission regions
Raj Prince, Michal Zajaček, S. Panda +24
We present the wavelength-resolved reverberation mapping (RM) of combined MgII and UV FeII broad-line emissions for two intermediate redshifts (z1), luminous quasars - HE 041…
