Multi-wavelength data handling in current and future surveys: the possible role of Virtual Observatory
C. Vignali, F. Fiore, A. Comastri +5
Here we review some of the main issues related to multi-wavelength source identification and characterization, with particular emphasis on the field of X-ray surveys carried out ov…
On the peculiar properties of the narrow-line quasar PG 1543+489
C. Vignali, E. Piconcelli, S. Bianchi +1
We present the analysis of four XMM-Newton observations of the narrow-line quasar PG 1543+489 at z=0.400 carried out over a rest-frame time-scale of about three years. The X-ray sp…
Analytical Approach to Subhaloes Population in Dark Matter Haloes
Carlo Giocoli, Lidia Pieri, Giuseppe Tormen
In the standard model of cosmic structure formation, dark matter haloes form by gravitational instability. The process is hierarchical: smaller systems collapse earlier, and later…
Nuclear star formation in the quasar PG1126-041 from adaptive optics assisted spectroscopy
G. Cresci, R. Maiolino, A. Marconi +2
We present adaptive optics assisted spectroscopy of three quasars obtained with NACO at VLT. The high angular resolution achieved with the adaptive optics (~0.08"), joined to the d…
The gas content of peculiar galaxies: strongly interacting systems
V. Casasola, D. Bettoni, G. Galletta
A study of the gas content in 1038 interacting galaxies, essentially selected from Arp, Arp and Madore, Vorontsov-Velyaminov catalogues and some of the published literature, is pre…
Optical Luminosity Functions of the Abell Galaxy Cluster ABCG 209 at z=0.21
A. Mercurio, M. Massarotti, P. Merluzzi +3
We derive the luminosity functions in three bands (BVR) for the rich galaxy cluster ABCG 209 at z=0.21. The data cover an area of ~78 arcmin^2 in the B and R bands, while a mosaic…
