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…
The host galaxy of OJ 287 revealed by optical and near-infrared imaging
K. Nilsson, J. Kotilainen, M. Valtonen +11
The BL Lacertae object OJ 287 (z = 0.306) has unique double-peaked optical outbursts every ~12 years, and it presents one of the best cases for a small-separation binary supermassi…
The Unique Blazar OJ 287 and its Massive Binary Black Hole Central Engine
Lankeswar Dey, Achamveedu Gopakumar, Mauri Valtonen +12
The bright blazar OJ 287 is the best-known candidate for hosting a nanohertz gravitational wave (GW) emitting supermassive binary black hole (SMBBH) in the present observable unive…
