Measuring the cosmic ray acceleration efficiency of a supernova remnant
E. A. Helder, J. Vink, C. G. Bassa +7
Cosmic rays are the most energetic particles arriving at earth. Although most of them are thought to be accelerated by supernova remnants, the details of the acceleration process a…
Testing the Dark Matter Interpretation of the PAMELA Excess through Measurements of the Galactic Diffuse Emission
Marco Regis, Piero Ullio
We propose to test the dark matter (DM) interpretation of the positron excess observed by the PAMELA cosmic-ray (CR) detector through the identification of a Galactic diffuse gamma…
What is Driving the HI Velocity Dispersion?
D. Tamburro, H. -W. Rix, A. K. Leroy +5
We explore what dominant physical mechanism sets the kinetic energy contained in neutral, atomic (HI) gas. We compare the HI line widths predicted from turbulence driven by superno…
Discovery of the first symbiotic star in NGC6822
A. Kniazev, P. Vaisanen, P. A. Whitelock +10
We report the discovery of the first symbiotic star (V=21.6, K_S=15.8 mag) in the Local Group dwarf irregular galaxy NGC6822. This star was identified during a spectral survey of H…
