Interstellar anatomy of the TeV gamma-ray peak in the IC443 supernova remnant

P. Dell'Ova, A. Gusdorf, M. Gerin +11

Supernovae remnants (SNRs) represent a major feedback source from stars on the interstellar medium of galaxies. During the latest stage of supernovae explosions, shock waves produc…

Unfolding the X-ray Spectral Curvature of Mkn 421 for Further Clues

Pranjupriya Goswami, Sunder Sahayanathan, Atreyee Sinha +1

The X-ray observations of Mkn 421 show significant spectral curvature that can be reproduced by a log-parabola function. The spectra can also be fitted by an analytical model consi…

Search for dark matter signals towards a selection of recently-detected DES dwarf galaxy satellites of the Milky Way with H.E.S.S

H. E. S. S. Collaboration, :, H. Abdallah +227

Dwarf spheroidal galaxy satellites of the Milky Way are prime targets for indirect detection of dark matter with gamma rays due to their proximity, high dark matter content and abs…

On the determination of log-normal flux distributions for astrophysical systems

Zahir Shah, Ranjeev Misra, Atreyee Sinha

Determining whether the flux distribution of an Astrophysical source is a Gaussian or a log-normal, provides key insight into the nature of its variability. For lightcurves of mode…

On the influence of supra-thermal particle acceleration on the morphology of low-Mach, high- shocks

Allard Jan van Marle

When two galaxy clusters encounter each other, the interaction results in a collisionless shock that is characterized by a low (1-4) sonic Mach number, and a high Alfv{é}nic Mach n…
