The supermassive black hole of Fornax A
N. Nowak, R. P. Saglia, J. Thomas +3
The radio galaxy Fornax A (NGC 1316) is a prominent merger remnant in the outskirts of the Fornax cluster. Its giant radio lobes suggest the presence of a powerful AGN and thus a c…
Spectroscopy of clusters in the ESO distant cluster survey (EDisCS).II. Redshifts, velocity dispersions, and substructure for clusters in the last 15 fields
Bo Milvang-Jensen, Stefan Noll, Claire Halliday +17
AIMS. We present spectroscopic observations of galaxies in 15 survey fields as part of the ESO Distant Cluster Survey (EDisCS). We determine the redshifts and velocity dispersions…
Detection of Very-High Energy Gamma-Rays from the BL Lac Object PG 1553+113 with the MAGIC Telescope
Robert Wagner, Daniela Dorner, Masaaki Hayashida +5
The MAGIC telescope has observed very-high energy gamma-ray emission from the BL Lac object PG 1553+113 in 2005 and 2006 at an overall significance is 8.8 sigma. The light curve sh…
The supermassive black hole in NGC4486a detected with SINFONI at the VLT
N. Nowak, R. P. Saglia, J. Thomas +4
The near-infrared integral field spectrograph SINFONI at the ESO VLT opens a new window for the study of central supermassive black holes. With a near-IR spatial resolution similar…
CHANDRA reveals galaxy cluster with the most massive nearby cooling core, RXCJ1504.1-0248
H. Boehringer, V. Burwitz, Y. -Y. Zhang +2
A CHANDRA follow-up observation of an X-ray luminous galaxy cluster with a compact appearance, RXCJ1504.1-0248 discovered in our REFLEX Cluster Survey, reveals an object with one o…
