Radio polarimetry as a probe of unresolved jets: the 2013 outburst of XTE J1908+094

P. A. Curran, J. C. A. Miller-Jones, A. P. Rushton +21

XTE J1908+094 is an X-ray transient black hole candidate in the Galactic plane that was observed in outburst in 2002 and 2013. Here we present multi-frequency radio and X-ray data,…

LOFAR discovery of a quiet emission mode in PSR B0823+26

C. Sobey, N. J. Young, J. W. T. Hessels +91

PSR B0823+26, a 0.53-s radio pulsar, displays a host of emission phenomena over timescales of seconds to (at least) hours, including nulling, subpulse drifting, and mode-changing.…

Exploring plasma evolution during Sagittarius A* flares

Salome Dibi, Sera Markoff, Renaud Belmont +3

We present a new way of describing the flares from Sgr A* with a self-consistent calculation of the particle distribution. All relevant radiative processes are taken into account i…

PIC simulation study of the interaction between a relativistically moving leptonic micro-cloud and ambient electrons

M. E. Dieckmann, G. Sarri, S. Markoff +2

The jets of compact accreting objects are composed of electrons and a mixture of positrons and ions. These outflows impinge on the interstellar or intergalactic medium and both pla…

Radio and Millimeter Monitoring of Sgr A*: Spectrum, Variability, and Constraints on the G2 Encounter

Geoffrey C. Bower, Sera Markoff, Jason Dexter +10

We report new observations with the Very Large Array, Atacama Large Millimeter Array, and Submillimeter Array at frequencies from 1.0 to 355 GHz of the Galactic Center black hole,…

ALMA and VLA measurements of frequency-dependent time lags in Sagittarius A*: evidence for a relativistic outflow

Christiaan D. Brinkerink, Heino Falcke, Casey J. Law +12

Radio and mm-wavelength observations of Sagittarius A* (Sgr A*), the radio source associated with the supermassive black hole at the center of our Galaxy, show that it behaves as a…
