Anisotropy and chemical composition of ultra-high energy cosmic rays using arrival directions measured by the Pierre Auger Observatory

The Pierre Auger Collaboration, P. Abreu, M. Aglietta +490

The Pierre Auger Collaboration has reported evidence for anisotropy in the distribution of arrival directions of the cosmic rays with energies eV. Thes…

The last Gamma Ray Burst in our Galaxy? On the observed cosmic ray excess at particle energy 1 EeV

Peter L. Biermann, Gustavo Medina-Tanco, Ralph Engel +1

Here we propose that the excess flux of particle events of energy near 1 EeV from the direction of the Galactic Center region is due to the production of cosmic rays by the last fe…

Stellar variability in low-extinction regions towards the Galactic Bulge

T. P. Dominici, J. E. Horvath, G. A. Medina Tanco +2

Intensive monitoring of low-extinction windows towards the galactic bulge has provided in the last years valuable information for studies about the dynamics, kinematics and formati…

Extension of Tycho catalog for low-extinction windows in the galactic bulge

T. P. Dominici, R. Teixeira, J. E. Horvath +2

We present in this work secondary catalogs up to based on the Tycho reference frame (ESA, 1997) for 12 selected low-extinction fields towards the galactic bulge.…

Dark matter halos and the anisotropy of ultra-high energy cosmic rays

Gustavo Medina Tanco, Alan A. Watson

Several explanations for the existence of Ultra High Energy Cosmic Rays invoke the idea that they originate from the decay of massive particles created in the reheating following i…

Magnetically Driven Outflows in a Starburst Environment

E. M. de Gouveia Dal Pino, G. A. Medina Tanco

We here investigate the possibility that the observed collimated outflows in luminous infrared galaxies (LIGs) and some Seyfert galaxies can be produced in a starburst (SB) environ…
