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…

Authenticating the Presence of a Relativistic Massive Black Hole Binary in OJ 287 Using its General Relativity Centenary Flare: Improved Orbital Parameters

Lankeswar Dey, M. J. Valtonen, A. Gopakumar +5

Results from regular monitoring of relativistic compact binaries like PSR 1913+16 are consistent with the dominant (quadrupole) order emission of gravitational waves (GWs). We show…

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…

MAGIC observations of variable very-high-energy gamma-ray emission from PKS1510-089 during May 2015 outburst

Julian Sitarek, Josefa Becerra González, Vandad Fallah Ramazani Elina Lindfors +11

PKS1510-089 is a flat spectrum radio quasar located at a redshift of 0.36. It is one of only a few such sources detected in very-high-energy (VHE, >100 GeV) gamma rays. Though PKS1…

Evidence for two Lognormal States in Multi-wavelength Flux Variation of FSRQ PKS 1510-089

Pankaj Kushwaha, Sunil Chandra, Ranjeev Misra +3

We present a systematic characterization of multi-wavelength emission from blazar PKS 1510-089 using well-sampled data at infrared(IR)-optical, X-ray and -ray energies. The resu…

Primary black hole spin in OJ287 as determined by the General Relativity centenary flare

M. J. Valtonen, S. Zola, S. Ciprini +87

OJ287 is a quasi-periodic quasar with roughly 12 year optical cycles. It displays prominent outbursts which are predictable in a binary black hole model. The model predicted a majo…
