Molecular clouds under the influence of massive stars in the Galactic HII region G353.2+0.9
A. Giannetti, J. Brand, F. Massi +2
The Galactic HII region G353.2+0.9 is excited by the massive open cluster Pismis-24. By analyzing (sub-)mm molecular-line and -continuum we study the detailed morphology of the gas…
Why are central radio relics so rare?
F. Vazza, M. Brueggen, R. van Weeren +3
In this paper we address the question why cluster radio relics that are connected to shock acceleration, so-called radio gischt, have preferentially been found in the outskirts of…
Young radio sources: the duty-cycle of the radio emission and prospects for gamma-ray emission
M. Orienti, D. Dallacasa, G. Giovannini +2
The evolutionary stage of a powerful radio source originated by an AGN is related to its linear size. In this context, compact symmetric objects (CSOs), which are powerful and intr…
Characterization of a tagged -ray beam line at the DANE Beam Test Facility

The H. E. S. S. Collaboration, :, A. Abramowski +442
Abridged: The giant radio galaxy M 87 with its proximity, famous jet, and very massive black hole provides a unique opportunity to investigate the origin of very high energy (VHE;…
Deep Chandra observation of the galaxy cluster WARPJ1415.1+3612 at z=1: an evolved cool-core cluster at high-redshift
Joana S. Santos, Paolo Tozzi, Piero Rosati +2
Using the deepest (370 ksec) Chandra observation of a high-redshift galaxy cluster, we perform a detailed characterization of the intra-cluster medium (ICM) of WARPJ1415.1+3612 at…
