Nature and evolution of powerful radio galaxies and their link with the quasar luminosity function
Sjoert van Velzen, Heino Falcke, Elmar Koerding
Current wide-area radio surveys are dominated by active galactic nuclei, yet many of these sources have no identified optical counterparts. Here we investigate whether one can cons…
LOFAR low-band antenna observations of the 3C295 and Bootes fields: source counts and ultra-steep spectrum sources
R. J. van Weeren, W. L. Williams, C. Tasse +98
We present LOFAR Low Band observations of the Bootes and 3C295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy beam, making them the dee…
Depth of Maximum of Air-Shower Profiles at the Pierre Auger Observatory: Composition Implications
Pierre Auger Collaboration
Using the data taken at the Pierre Auger Observatory between December 2004 and December 2012, we have examined the implications of the distributions of depths of atmospheric shower…
A search for point sources of EeV photons
Pierre Auger Collaboration, A. Aab, P. Abreu +483
Measurements of air showers made using the hybrid technique developed with the fluorescence and surface detectors of the Pierre Auger Observatory allow a sensitive search for point…
Origin of atmospheric aerosols at the Pierre Auger Observatory using studies of air mass trajectories in South America
Pierre Auger Collaboration, Gabriele Curci
The Pierre Auger Observatory is making significant contributions towards understanding the nature and origin of ultra-high energy cosmic rays. One of its main challenges is the mon…
The Very Large Array Low-frequency Sky Survey Redux (VLSSr)
W. M. Lane, W. D. Cotton, S. van Velzen +5
We present the results of a recent re-reduction of the data from the Very Large Array (VLA) Low-frequency Sky Survey (VLSS). We used the VLSS catalog as a sky model to correct the…
