Discovery of luminous pulsed hard X-ray emission from anomalous X-ray pulsars 1RXS J1708-4009, 4U 0142+61 and 1E 2259+586 by INTEGRAL and RXTE
L. Kuiper, W. Hermsen, P. R. den Hartog +1
We report on the discovery of hard spectral tails for energies above 10 keV in the total and pulsed spectra of anomalous X-ray pulsars 1RXS J1708-4009, 4U 0142+61 and 1E 2259+586 u…
Type 1 AGN and their Link to ULIRGS
Paola Andreani
Increasing observational evidence supports a picture for a close link among AGN phenomenum, star-formation processes and galaxy formation. Since the physical phenomena related to t…
Extremely Red Galaxies
Paola Andreani, Andrea Cimatti, Huub Roettgering +1
Preliminary results of a project aiming at unveiling the nature of the extremely red galaxies (ERGs) (objects with colours R-K>6 and I-K>5) found in deep optical-NIR surveys are pr…
Large-scale structures in the distribution of X-ray selected AGN
D. Engels, F. Tesch, C. Ledoux +5
We are searching for large-scale structures in the distribution of AGN discovered by the ROSAT All-Sky Survey. The RASS detected > 60000 X-ray objects, of which approximately 35% a…
