First LOFAR observations of gamma-ray binaries

AIP Conference Proceedings 1505 (2012) 374-377

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.

Infrared spectroscopy of nearby radio active elliptical galaxies

Astrophysical Journal, Supplement Series 203:1 (2012)

Authors:

J Mould, T Reynolds, T Readhead, D Floyd, B Jannuzi, G Cotter, L Ferrarese, K Matthews, D Atlee, M Brown

Abstract:

In preparation for a study of their circumnuclear gas we have surveyed 60% of a complete sample of elliptical galaxies within 75 Mpc that are radio sources. Some 20% of our nuclear spectra have infrared emission lines, mostly Paschen lines, Brackett γ, and [Fe II]. We consider the influence of radio power and black hole mass in relation to the spectra.
