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…
Refinement of the convex shape model and tumbling spin state of (99942) Apophis using the 2020-2021 apparition data
H. -J. Lee, M. -J. Kim, A. Marciniak +30
Context. The close approach of the near-Earth asteroid (99942) Apophis to Earth in 2029 will provide a unique opportunity to examine how the physical properties of the asteroid cou…
Detection of Possible Quasi-periodic Oscillations in the Long-term Optical Light Curve of the BL Lac Object OJ 287
G. Bhatta, S. Zola, Ł. Stawarz +12
Detection of periodicity in the broad-band non-thermal emission of blazars has so far been proven to be elusive. However, there are a number of scenarios which could lead to quasi-…
New and updated convex shape models of asteroids based on optical data from a large collaboration network
J. Hanuš, J. Ďurech, D. A. Oszkiewicz +165
Asteroid modeling efforts in the last decade resulted in a comprehensive dataset of almost 400 convex shape models and their rotation states. This amount already provided a deep in…
Precursor flares in OJ 287
P. Pihajoki, M. Valtonen, S. Zola +19
We have studied three most recent precursor flares in the light curve of the blazar OJ 287 while invoking the presence of a precessing binary black hole in the system to explain th…
