Relativistic Jet from Black Hole

An artist's impression of a relativistic jet propagating away from a black hole at close to the speed of light. Such jets are formed by the inner regions of the accretion flow: matter flowing inwards towards the black hole, via processes which are not yet fully understood. The accretion flow emits primarily in X-rays, the relativistic jet in the radio band: by combing observations in each band we can try and understand how such jets form and how much energy they carry away from the black hole.

First LOFAR observations of gamma-ray binaries

AIP Conference Proceedings 1505 (2012) 374-377

Authors:

B Marcote, M Ribó, JM Paredes, J Swinbank, J Broderick, R Fender, S Markoff, R Wijers

Abstract:

A few binary systems display High Energy (100 MeV-100 GeV) and/or Very High Energy (≳ 100 GeV) gamma-ray emission. These systems also display non-thermal radio emission+that can be resolved with long-baseline radio interferometers, revealing the presence of outflows. It is expected that at very low frequencies the synchrotron radio emission covers larger angular scales than has been reported up to now. Here we present preliminary results of the first deep radio observations of the gamma-ray binary LS I +61 303 with LOFAR, which is sensitive to extended structures on arcsecond to arcminute scales. © 2012 American Institute of Physics.
