Correlating spectral and timing properties in the evolving jet of the micro blazar MAXI J1836-194

M. Lucchini, T. D. Russell, S. B. Markoff +4

During outbursts, the observational properties of black hole X-ray binaries (BHXBs) vary on timescales of days to months. These relatively short timescales make these systems ideal…

Disk-jet coupling changes as a possible indicator for outbursts from GX 339-4 remaining within the X-ray hard state

S. E. M. de Haas, T. D. Russell, N. Degenaar +8

We present quasi-simultaneous radio, (sub-)millimetre, and X-ray observations of the Galactic black hole X-ray binary GX 339-4, taken during its 2017--2018 outburst, where the sour…

General relativistic MHD simulations of non-thermal flaring in Sagittarius A*

Koushik Chatterjee, Sera Markoff, Joseph Neilsen +10

Sagittarius A* exhibits regular variability in its multiwavelength emission, including daily X-ray flares and roughly continuous near-infrared (NIR) flickering. The origin of this…

A new lepto-hadronic model applied to the first simultaneous multiwavelength data set for Cygnus X--1

D. Kantzas, S. Markoff, T. Beuchert +10

Cygnus X--1 is the first Galactic source confirmed to host an accreting black hole. It has been detected across the entire electromagnetic spectrum from radio to GeV -rays. The…

Gravitational Test Beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole

Dimitrios Psaltis, Lia Medeiros, Pierre Christian +185

The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new…

Sensitivity of the Cherenkov Telescope Array for probing cosmology and fundamental physics with gamma-ray propagation

The Cherenkov Telescope Array Consortium, :, H. Abdalla +496

The Cherenkov Telescope Array (CTA), the new-generation ground-based observatory for -ray astronomy, provides unique capabilities to address significant open questions in astrop…
