Diffuse radio emission in the galaxy cluster SPT-CL J2031-4037: a steep spectrum intermediate radio halo?
Ramij Raja, Majidul Rahaman, Abhirup Datta +6
The advent of sensitive low frequency radio observations has revealed a number of diffuse radio objects with peculiar properties that are challenging our understanding about the ph…
An image-based search for pulsars among Fermi unassociated LAT sources
D. A. Frail, P. S. Ray, K. P. Mooley +9
We describe an image-based method that uses two radio criteria, compactness and spectral index, to identify promising pulsar candidates among Fermi Large Area Telescope (LAT) unass…
Pulsar Candidates Toward Fermi Unassociated Sources
D. A. Frail, K. P. Mooley, P. Jagannathan +1
We report on a search for steep spectrum radio sources within the 95% confidence error ellipses of the Fermi unassociated sources from the Large Array Telescope (LAT). Using existi…
A large light-mass component of cosmic rays at 10^{17} - 10^{17.5} eV from radio observations
S. Buitink, A. Corstanje, H. Falcke +101
Cosmic rays are the highest energy particles found in nature. Measurements of the mass composition of cosmic rays between 10^{17} eV and 10^{18} eV are essential to understand whet…
LOFAR, VLA, and Chandra observations of the Toothbrush galaxy cluster
R. J. van Weeren, G. Brunetti, M. Brüggen +39
We present deep LOFAR observations between 120-181 MHz of the "Toothbrush" (RX J0603.3+4214), a cluster that contains one of the brightest radio relic sources known. Our LOFAR obse…
A powerful double radio relic system discovered in PSZ1 G108.18-11.53: evidence for a shock with non-uniform Mach number?
F. de Gasperin, H. T. Intema, R. J. van Weeren +5
Diffuse radio emission in the form of radio halos and relics has been found in a number of merging galaxy clusters. These structures indicate that shock and turbulence associated w…
