The finding that massive galaxies grow with cosmic time fired the starting gun for the search of objects which could have survived up to the present day without...
We observed the optical and NIR counterpart of the recently discovered X-ray transient MAXI J1659-152 (Negoro et al. 2010, ATel #2873; Mangano et al. 2010, GCN...
Remote sensing of the solar photosphere: a tale of two methods
Solar spectro-polarimetry is a powerful tool to investigate the physical processes occurring in the solar atmosphere. The different states of polarization and...
Renewed activity of the neutron star X-ray transient SAX J1747.0-2853
An X-ray transient was detected in outburst on 18 October 2005 during one of our Chandra/HRC-I observations as part of the XMM-Newton/Chandra monitoring...
Renewed activity of the very faint X-ray transient CXOGC J174535.5-290124 and continued activity of the neutron-star X-ray transient SAX J1747.0-2853
On 8-9 September 2006, a series of 7 XMM-Newton observations were performed as part of our XMM-Newton/Chandra monitoring campaign of the 1.7 square degree...
Renewed optical and X-ray activity in IGR J00291+5934
We report a re-brightening of the millisecond X-ray pulsar IGR J00291+5934. In August the source performed an outburst which was detected in X-ray, UV and...
