Molecular Clouds as Cosmic Ray Laboratories

Sabrina Casanova, Felix A. Aharonian, Yasuo Fukui +9

We will here discuss how the gamma-ray emission from molecular clouds can be used to probe the cosmic ray flux in distant regions of the Galaxy and to constrain the highly unknown…

The Milky Way Heart: Investigating molecular gas and gamma-ray morphologies in the Central Molecular Zone

David I. Jones, Michael Burton, Paul Jones +3

Since the discovery of a broad distribution of very high energy (VHE; >0.1 TeV) gamma-rays in the Central Molecular Zone (CMZ) of the Galaxy in 2006 by the HESS collaboration, the…

Search for Lorentz Invariance breaking with a likelihood fit of the PKS 2155-304 flare data taken on MJD 53944

HESS Collaboration, A. Abramowski, F. Acero +193

Several models of Quantum Gravity predict Lorentz Symmetry breaking at energy scales approaching the Planck scale (10^{19} GeV). With present photon data from the observations of d…

H.E.S.S. constraints on Dark Matter annihilations towards the Sculptor and Carina Dwarf Galaxies

HESS Collaboration, A. Abramowski, F. Acero +192

The Sculptor and Carina Dwarf spheroidal galaxies were observed with the H.E.S.S. Cherenkov telescope array between January 2008 and December 2009. The data sets consist of a total…

H.E.S.S. observations of massive stellar clusters

Stefan Ohm, Dieter Horns, Olaf Reimer +6

Stellar clusters are potential acceleration sites of very-high-energy (VHE, E > 100GeV) particles since they host supernova remnants (SNRs) and pulsar wind nebulae (PWNe). Addition…

Looking Into the Fireball: ROTSE-III and Swift Observations of Early GRB Afterglows

E. S. Rykoff, F. Aharonian, C. W. Akerlof +21

We report on a complete set of early optical afterglows of gamma-ray bursts (GRBs) obtained with the ROTSE-III telescope network from March 2005 through June 2007. This set is comp…
