Prompt TeV Emission from Cosmic Rays Accelerated by Gamma Ray Bursts Interacting with Surrounding Stellar Wind

Soebur Razzaque, Olga Mena, Charles D. Dermer

Protons accelerated in the internal shocks of a long duration gamma ray burst can escape the fireball as cosmic rays by converting to neutrons. Hadronic interactions of these neutr…

Ultra High Energy Cosmic Rays from Black Hole Jets of Radio Galaxies

C. D. Dermer, S. Razzaque, J. D. Finke +1

The Auger Collaboration reports that the arrival directions of >60 EeV ultra-high energy cosmic rays (UHECRs) cluster along the supergalactic plane and correlate with active galact…

The Heating of Thermal Electrons in Fast Collisionless Shocks: The Integral Role of Cosmic Rays

Cara E. Rakowski, J. Martin Laming, Parviz Ghavamian

Understanding the heating of electrons to quasi-thermal energies at collisionless shocks has broad implications for plasma astrophysics. It directly impacts the interpretation of X…

Tidal tails around globular clusters. Are they a good tracer of cluster orbits?

M. Montuori, R. Capuzzo-Dolcetta, P. Di Matteo +2

We present the results of detailed N-body simulations of clusters moving in a realistic Milky Way (MW) potential. The strong interaction with the bulge and the disk of the Galaxy l…

Extremely compact massive galaxies at z~1.4

I. Trujillo, G. Feulner, Y. Goranova +9

The optical rest-frame sizes of 10 of the most massive (~5x10^{11}h_{70}^{-2}M_sun) galaxies found in the near-infrared MUNICS survey at 1.2<z<1.7 are analysed. Sizes were estimate…
