Simultaneous X-ray and Infrared Observations of Sagittarius A*'s Variability

H. Boyce, D. Haggard, G. Witzel +11

Emission from Sgr A* is highly variable at both X-ray and infrared (IR) wavelengths. Observations over the last ~20 years have revealed X-ray flares that rise above a quiescent the…

Breaking degeneracy in jet dynamics: multi-epoch joint modelling of the BL Lac PKS 2155-304

M. Lucchini, S. Markoff, P. Crumley +2

Supermassive black holes can launch powerful jets which can be some of the most luminous multi-wavelength sources; decades after their discovery their physics and energetics are st…

Tracking the variable jets of V404 Cygni during its 2015 outburst

A. J. Tetarenko, G. R. Sivakoff, J. C. A. Miller-Jones +14

We present multi-frequency monitoring observations of the black hole X-ray binary V404 Cygni throughout its June 2015 outburst. Our data set includes radio and mm/sub-mm photometry…

Kinetic simulations of mildly relativistic shocks I: particle acceleration in high Mach number shocks

Patrick Crumley, Damiano Caprioli, Sera Markoff +1

We use fully kinetic particle-in-cell simulations with unprecedentedly large transverse box sizes to study particle acceleration in weakly-magnetized mildly relativistic shocks tra…

A wildly flickering jet in the black hole X-ray binary MAXI J1535-571

M. C. Baglio, D. M. Russell, P. Casella +29

We report on the results of optical, near-infrared (NIR) and mid-infrared observations of the black hole X-ray binary candidate (BHB) MAXI J1535-571 during its 2017/2018 outburst.…

LOFAR 150-MHz observations of SS 433 and W 50

J. W. Broderick, R. P. Fender, J. C. A. Miller-Jones +28

We present LOFAR high-band data over the frequency range 115-189 MHz for the X-ray binary SS 433, obtained in an observing campaign from 2013 February - 2014 May. Our results inclu…
