Q0045-3337: models including strong lensing by a spiral galaxy
M. Chieregato, M. Miranda, P. Jetzer
Aims. Falomo et al. (2005) discovered a disk-like galaxy at ~ 1.2 arcsec from the QSO Q0045-3337 by means of ESO VLT adaptive optics. They estimated a galaxy Einstein radius (for a…
Persistent and Transient Blank Field Sources
A. Treves, S. Campana, M. Chieregato +3
Blank field sources (BFS) are good candidates for hosting dim isolated neutron stars (DINS). The results of a search of BFS in the ROSAT HRI images are revised. We then focus on tr…
Blank Field Sources in the ROSAT HRI Brera Multiscale Wavelet catalog
M. Chieregato, S. Campana, A. Treves +3
The search for Blank Field Sources (BFS), i.e. X-ray sources without optical counterparts, paves the way to the identification of unusual objects in the X-ray sky. Here we present…
Detection of pulsations and a spectral feature in the X-ray emission of the isolated neutron star 1RXS J214303.7+065419/RBS 1774
S. Zane, M. Cropper, R. Turolla +4
We report on the results of a deep XMM-Newton observation of RBS 1774, the most recent dim isolated neutron star candidate found in the ROSAT archive data. Spectral and timing anal…
The Ultraluminous X-ray Source NGC 1313 X-2 (MS 0317.7-6647) and its Environment
L. Zampieri, P. Mucciarelli, R. Falomo +5
We present new optical and {\it Chandra} observations of the field containing the ultraluminous X-ray source NGC 1313 X-2. On an ESO 3.6 m image, the {\it Chandra} error box embrac…
Optical Counterpart of The Ultraluminous X-ray Source NGC 1313 X-2
L. Zampieri, P. Mucciarelli, R. Falomo +5
We present new optical and {\it Chandra} observations of the field containing the ultraluminous X-ray source NGC1313 X-2. On an ESO 3.6 m image, the {\it Chandra} error box embrace…
1RXS J214303.7+065419/RBS 1774: A New Isolated Neutron Star Candidate
L. Zampieri, S. Campana, R. Turolla +5
We report on the identification of a new possible Isolated Neutron Star candidate in archival ROSAT observations. The source 1RXS J214303.7+065419, listed in the ROSAT Bright Surve…
