The Optical Two and Three-Dimensional Fundamental Plane Correlations for Nearly 180 Gamma-Ray Burst Afterglows with Swift/UVOT, RATIR, and the SUBARU Telescope
Maria Giovanna Dainotti, Sam Young, L. Li +21
Gamma-ray bursts (GRBs) are fascinating events due to their panchromatic nature. We study optical plateaus in GRB afterglows via an extended search into archival data. We comprehen…
Multi-band behaviour of the TeV blazar PG 1553+113 in optical range on diverse timescales
A. Agarwal, B. Mihov, I. Andruchow +11
Context. The TeV BL Lac object PG 1553+113 is one of the primary candidates for a binary supermassive black hole system. Aims. We study the flux and spectral variability of PG 1553…
Spitzer Observations of the Predicted Eddington Flare from Blazar OJ 287
Seppo Laine, Lankeswar Dey, Mauri Valtonen +25
Binary black hole (BH) central engine description for the unique blazar OJ 287 predicted that the next secondary BH impact-induced bremsstrahlung flare should peak on 2019 July 31.…
High accuracy measurement of gravitational wave back-reaction in the OJ287 black hole binary
Mauri J. Valtonen, L. Dey, R. Hudec +16
Blazar OJ287 exhibits large thermal flares at least twice every 12 years. The times of these flares have been predicted successfully using the model of a quasi-Keplerian eccentric…
Signatures of the disk-jet coupling in the Broad-line Radio Quasar 4C+74.26
G. Bhatta, L. Stawarz, A. Markowitz +16
Here we explore the disk-jet connection in the broad-line radio quasar 4C+74.26, utilizing the results of the multiwavelength monitoring of the source. The target is unique in that…
Stochastic modeling of multiwavelength variability of the classical BL Lac object OJ 287 on timescales ranging from decades to hours
A. Goyal, L. Stawarz, S. Zola +109
We present the results of our power spectral density analysis for the BL Lac object OJ\,287, utilizing the {\it Fermi}-LAT survey at high-energy -rays, {\it Swift}-XRT in X-rays…
