Simultaneous Monitoring of X-ray and Radio Variability in Sagittarius A*
Daniel M. Capellupo, Daryl Haggard, Nicolas Choux +14
Monitoring of Sagittarius A* from X-ray to radio wavelengths has revealed structured variability --- including X-ray flares --- but it is challenging to establish correlations betw…
Sagittarius A* High Energy X-ray Flare Properties During NuSTAR Monitoring of the Galactic Center from 2012 to 2015
Shuo Zhang, Frederick K. Baganoff, Gabriele Ponti +17
Understanding the origin of the flaring activity from the Galactic center supermassive black hole, Sagittarius A*, is a major scientific goal of the NuSTAR Galactic plane survey ca…
Accretion-ejection morphology of the microquasar SS433 resolved at sub-au scale
GRAVITY Collaboration, P. -O. Petrucci, I. Waisberg +67
We present the first optical observation at sub-milliarcsecond (mas) scale of the microquasar SS 433 obtained with the GRAVITY instrument on the VLT interferometer. The 3.5 hour ex…
A powerful flare from Sgr A* confirms the synchrotron nature of the X-ray emission
G. Ponti, E. George, S. Scaringi +21
We present the first fully simultaneous fits to the NIR and X-ray spectral slope (and its evolution) during a very bright flare from Sgr A*, the supermassive black hole at the Milk…
A transient, flat spectrum radio pulsar near the Galactic centre
J. Dexter, N. Degenaar, M. Kerr +6
Recent studies have shown possible connections between highly magnetized neutron stars ("magnetars"), whose X-ray emission is too bright to be powered by rotational energy, and ord…
Faraday rotation in GRMHD simulations of the jet launching zone of M87
Monika Moscibrodzka, Jason Dexter, Jordy Davelaar +1
Non-VLBI measurements of Faraday rotation at mm wavelengths have been used to constrain mass accretion rates ($\mdot$) onto supermassive black holes in the centre of the Milky Way…
