Investigating the mini and giant radio flare episodes of Cygnus X-3

E. Egron, A. Pellizzoni, S. Righini +16

The microquasar Cygnus X-3 underwent a giant radio flare in April 2017, reaching a maximum flux of Jy at 8.5 GHz. We present results from a long monitoring campaign car…

Superorbital Modulation in the High-Mass X-ray Binary 4U 1538-52, and Possible Modulation in IGR J16393-4643

Robin H. D. Corbet, Joel B. Coley, Hans A. Krimm +2

Hard X-ray observations with the Neil Gehrels Swift Observatory Burst Alert Telescope (BAT) reveal superorbital modulation in the wind-accreting supergiant high-mass X-ray binary (…

NuSTAR observation of GRO J1744-28 at low mass accretion rate

O. König, F. Fürst, P. Kretschmar +8

We present the spectral analysis of the LMXB GRO J1744-28 using 29 ks of NuSTAR data taken in 2017 February at a low luminosity of erg/s (3-50 keV). The c…

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,…

The cyclotron line energy in Her X-1: stable after the decay

R. Staubert, L. Ducci, L. Ji +6

We summarize the results of a dedicated effort between 2012 and 2019 to follow the evolution of the cyclotron line in Her~X-1 through repeated NuSTAR observations. The previously o…
