Optical variability of eight FRII-type quasars with 13-yr photometric light curves
Agnieszka Kuźmicz, Arti Goyal, Stanisław Zola +7
We characterize the optical variability properties of eight lobe-dominated radio quasars (QSOs): B2 070937, FBQS J095206.3235245, PG 1004130, [HB89] 1156631, [HB89] 142…
Host galaxy magnitude of OJ 287 from its colours at minimum light
Mauri J. Valtonen, Lankeswar Dey, S. Zola +54
OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…
Changing look AGN Mrk 590: Broad line region and black hole mass from photometric reverberation mapping
Amit Kumar Mandal, Malte Schramm, Suvendu Rakshit +9
We present the results of photometric reverberation mapping observations on the changing look active galactic nucleus Mrk 590 at z = 0.026. The observations were carried out from J…
