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…
Evolving optical polarisation of the black hole X-ray binary MAXI J1820+070
A. Veledina, A. V. Berdyugin, I. A. Kosenkov +8
Aims. The optical emission of black hole transients increases by several magnitudes during the X-ray outbursts. Whether the extra light arises from the X-ray heated outer disc, fro…
Mapping the Interstellar Magnetic Field Around the Heliosphere with Polarized Starlight
P. C. Frisch, A. B. Berdyugin, V. Piirola +20
Starlight that becomes linearly polarized by magnetically aligned dust grains provides a viable diagnostic of the interstellar magnetic field (ISMF). A survey is underway to map th…
Polarimetry and Spectroscopy of the `Oxygen Flaring' DQ Herculis-like nova: V5668 Sagittarii (2015)
E. J. Harvey, M. P. Redman, M. J. Darnley +5
Classical novae are eruptions on the surface of a white dwarf in a binary system. The material ejected from the white dwarf surface generally forms an axisymmetric shell of gas and…
