Proton acceleration in colliding stellar wind binaries
Emanuele Grimaldo, Anita Reimer, Ralf Kissmann +2
The interaction between the strong winds in stellar colliding-wind binary (CWB) systems produces two shock fronts, delimiting the wind collision region (WCR). There, particles are…
A -ray determination of the Universe's star-formation history
LAT Collaboration, M. Ajello, K. Helgason +4
The light emitted by all galaxies over the history of the Universe produces the extragalactic background light (EBL) at ultraviolet, optical, and infrared wavelengths. The EBL is a…
Cascading Constraints from Neutrino Emitting Blazars: The case of TXS 0506+056
Anita Reimer, Markus Boettcher, Sara Buson
We present a procedure to generally constrain the environments of neutrino-producing sites in photomeson production models of jetted Active Galactic Nuclei (AGN) where any origin o…
Unresolved Gamma-Ray Sky through its Angular Power Spectrum
M. Ackermann, M. Ajello, L. Baldini +107
The gamma-ray sky has been observed with unprecedented accuracy in the last decade by the Fermi large area telescope (LAT), allowing us to resolve and understand the high-energy Un…
Particle Transport within the Pulsar Wind Nebula HESS J1825-137
H. E. S. S. Collaboration, H. Abdalla, F. Aharonian +225
Aims: We present a detailed view of the pulsar wind nebula (PWN) HESS J1825-137. We aim to constrain the mechanisms dominating the particle transport within the nebula, accounting…
VHE -ray discovery and multi-wavelength study of the blazar 1ES 2322-409
H. E. S. S. Collaboration, :, H. Abdalla +232
A hotspot at a position compatible with the BL Lac object 1ES 2322-409 was serendipitously detected with H.E.S.S. during observations performed in 2004 and 2006 on the blazar PKS 2…
