Physical properties and evolutionary state of the Lyman alpha emitting starburst galaxy IRAS 08339+6517

Hakim Atek

Context. Though Ly alpha emission is one of the most used tracers of massive star formation at high redshift, it is strongly affected by neutral gas radiation transfer effects. A correct understanding of these effects is required to properly quantify the s ...

Diffuse gamma-ray constraints on dark matter revisited I: the impact of subhalos

Steve Blanchet

We make a detailed analysis of the indirect diffuse gamma-ray signals from dark matter annihilation in the Galaxy. We include the prompt emission, as well as the emission from inverse Compton scattering whenever the annihilation products contain light lept ...

Novel technique for supernova detection with IceCube

Mathieu Ribordy

The current supernova detection technique used in IceCube relies on the sudden deviation of the summed photomultiplier noise rate from its nominal value during the neutrino burst, making IceCube a approximate to 3 Megaton effective detection volume - class ...

Observations Of The Gas Reservoir Around A Star-Forming Galaxy In The Early Universe

Georges Meylan

We present a high signal-to-noise spectrum of a bright galaxy at z = 4.9 in 14 hr of integration on VLT FORS2. This galaxy is extremely bright, i(850) = 23.10 +/- 0.01, and is strongly lensed by the foreground massive galaxy cluster A1689 (z = 0.18). Stell ...
