Multi-band optical photometric variability of the blazar OJ 287 from 2015 to 2025
Alok C. Gupta, Karan Dogra, Mark Kidger +101
We present the most densely sampled multi-band optical photometric observations of the peculiar BL Lacertae object OJ 287 from 2015 to 2025 with a focus on its optical activity on…
Revisiting Blueshift Interpretation In Light Of Recent Discovery Of Multiple Systems Of Quasars
Justin Singh, Shirin Haque
This study investigates the anomalies associated with redshifts from emission lines in certain quasar candidates and the viability of a blueshift interpretation instead. The sample…
Relativistic Effects on Triple Black Holes: Burrau's Problem Revisited
Ariel Chitan, Aleksandr Mylläri, Shirin Haque
We explore, using numerical simulations, the influence of mass and distance on the evolution of triple black hole systems. Following in the direction of Burrau's famous 3,4,5 probl…
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.…
A Fractal Analysis of Magnetograms within Active Regions
Brandon Rajkumar, Shirin Haque
The magnetograms of sixteen Active Regions, observed during June - November 2015, were obtained from the Joint Science Operations Center and used to determine the fractal dimension…
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…
