High energy phenomena in the Cartwheel's ring
Anna Wolter, Ginevra Trinchieri, Angela Iovino
We present the first X-ray detection of the Cartwheel's ring. The impact that created the characteristic optical structure is responsible also for an enhanced level of star formati…
EISily looking for distant galaxy clusters
Catarina Lobo, Davide Lazzati, Angela Iovino +2
We present a new algorithm to search for distant clusters of galaxies on catalogues deriving from imaging data, as those of the ESO Imaging Survey. We discuss the advantages of our…
Spectroscopy of the optical Einstein ring 0047-2808
S. J. Warren, A. Iovino, P. C. Hewett +1
We present optical and near-infrared spectroscopic observations of the optical Einstein ring 0047-2808. We detect both [OIII] lines 4959, 5007 near 2.3 micron, confirming the redsh…
