Measurement of the extragalactic background light imprint on the spectra of the brightest blazars observed with H.E.S.S

H. E. S. S. Collaboration, :, A. Abramowski +195

The extragalactic background light (EBL) is the diffuse radiation with the second highest energy density in the Universe after the cosmic microwave background. The aim of this stud…

Probing the extent of the non-thermal emission from the Vela X region at TeV energies with H.E.S.S

A. Abramowski, F. Acero, F. Aharonian +196

Vela X is a region of extended radio emission in the western part of the Vela constellation: one of the nearest pulsar wind nebulae (PWNe), and associated with the energetic Vela p…

Constraints on cosmic-ray efficiency in the supernova remnant RCW 86 using multi-wavelength observations

M. Lemoine-Goumard, M. Renaud, J. Vink +4

Several young supernova remnants (SNRs) have recently been detected in the high-energy and very-high-energy gamma-ray domains. As exemplified by RX J1713.7-3946, the nature of this…

Search for Spatially Extended Fermi-LAT Sources Using Two Years of Data

Joshua Lande, Markus Ackermann, Alice Allafort +10

Spatial extension is an important characteristic for correctly associating gamma-ray-emitting sources with their counterparts at other wavelengths and for obtaining an unbiased mod…

GeV Observations of Star-forming Galaxies with \textit{Fermi} LAT

Fermi LAT Collaboration, M. Ackermann, M. Ajello +127

Recent detections of the starburst galaxies M82 and NGC 253 by gamma-ray telescopes suggest that galaxies rapidly forming massive stars are more luminous at gamma-ray energies comp…

Fermi-LAT Observations of the Diffuse Gamma-Ray Emission: Implications for Cosmic Rays and the Interstellar Medium

LAT Collaboration

The gamma-ray sky >100 MeV is dominated by the diffuse emissions from interactions of cosmic rays with the interstellar gas and radiation fields of the Milky Way. Observations of t…

Anisotropies in the diffuse gamma-ray background measured by the Fermi LAT

M. Ackermann, M. Ajello, A. Albert +134

The contribution of unresolved sources to the diffuse gamma-ray background could induce anisotropies in this emission on small angular scales. We analyze the angular power spectrum…
