Advances in Understanding High-Mass X-ray Binaries with INTEGRAL and Future Directions

Peter Kretschmar, Felix Fürst, Lara Sidoli +48

High mass X-ray binaries are among the brightest X-ray sources in the Milky Way, as well as in nearby Galaxies. Thanks to their highly variable emissions and complex phenomenology,…

Multi-wavelength observations of PSRJ 2032+4127 during the 2017 periastron passage

Maria Chernyakova, Denys Malyshev, Pere Blay +2

PSRJ 2032+4127 is only the second known gamma-ray binary where it is confirmed that a young radio pulsar is in orbit around a Be-star. The interaction of the pulsar wind with the m…

Multiwavelength observations of GRB 140629A. A long burst with an achromatic jet break in the optical and X-ray afterglow

Y. -D. Hu, S. R. Oates, V. M. Lipunov +31

We investigate the long GRB140629A through multiwavelength observations, which cover optical, infrared and X-rays between 40s and 3yr after the burst, to derive the properties of t…

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…

Multi-frequency observations of SWIFT J1626.6-5156

P. Reig, E. Nespoli, J. Fabregat +1

SWIFT J1626.6-5156 is an X-ray pulsar that was discovered in December 2005 during an X-ray outburst. Although the X-ray data suggest that the system is a high-mass X-ray binary, ve…
