A cosmic-ray positron anisotropy due to two middle-aged, nearby pulsars?
(IOP Publishing, 2008)
Geminga and B0656+14 are the closest pulsars with characteristic ages in the range of 100 kyr to 1 Myr. They both have spin-down powers of the order 3 × 1034 ergs s–1 at present. The winds of these pulsars had most probably ...
Spectral analysis and interpretation of the Y-ray emission from the starburst galaxy NGC 253
(IOP Publishing, 2012)
Very high energy (VHE; E ≥ 100 GeV) and high-energy (HE; 100 MeV ≤ E ≤ 100 GeV) data from γ-ray observations performed with the H.E.S.S. telescope array and the Fermi-LAT instrument, respectively, are analyzed in order to ...
