Detecting cosmic rays with the LOFAR radio telescope
P. Schellart, A. Nelles, S. Buitink +102
The low frequency array (LOFAR), is the first radio telescope designed with the capability to measure radio emission from cosmic-ray induced air showers in parallel with interferom…
Cosmic-ray spectral anomaly at GeV-TeV energies as due to re-acceleration by weak shocks in the Galaxy
Satyendra Thoudam, Jörg R. Hörandel
Recent cosmic-ray measurements by the ATIC, CREAM and PAMELA experiments have found an apparent hardening of the energy spectrum at TeV energies. Although the origin of the hardeni…
LOFAR: The LOw-Frequency ARray
M. P. van Haarlem, M. W. Wise, A. W. Gunst +197
LOFAR, the LOw-Frequency ARray, is a new-generation radio interferometer constructed in the north of the Netherlands and across europe. Utilizing a novel phased-array design, LOFAR…
Detecting Radio Emission from Air Showers with LOFAR
Anna Nelles, Stijn Buitink, Arthur Corstanje +11
LOFAR (the Low Frequency Array) is the largest radio telescope in the world for observing low frequency radio emission from 10 to 240 MHz. In addition to its use as an interferomet…
Fermi bubble -rays as a result of diffusive injection of Galactic cosmic rays
Satyendra Thoudam
Recently, the {\it{Fermi}} space telescope has discovered two large -ray emission regions, the so-called "Fermi bubbles", that extend up to above and below the G…
Revisiting the hardening of the cosmic-ray energy spectrum at TeV energies
Satyendra Thoudam, Jörg R. Hörandel
Measurements of cosmic rays by experiments such as ATIC, CREAM, and PAMELA indicate a hardening of the cosmic-ray energy spectrum at TeV energies. In our recent work (Thoudam & Hör…
