Broad-line region size and black hole mass in high-z AGN
Ismael Botti, Paulina Lira, Hagai Netzer +3
In this contribution we briefly review the reverberation mapping technique and its results for low and intermidiate luminosity AGNs. Then we present a monitoring campaign of high-l…
The Realm of the First Quasars in the Universe: the X-ray View
C. Vignali, W. N. Brandt, O. Shemmer +3
We review the X-ray studies of the highest redshift quasars, focusing on the results obtained with Chandra and XMM-Newton. Overall, the X-ray and broad-band properties of z>4 quasa…
Silicates in D-type symbiotic stars: an ISO overview
R. Angeloni, M. Contini, S. Ciroi +1
We investigate the IR spectral features of a sample of D-type symbiotic stars. Analyzing unexploited ISO-SWS data, deriving the basic observational parameters of dust bands and com…
Particle modeling of disk-shaped galaxies of stars on nowadays concurrent supercomputers
Evgeny Griv, Michael Gedalin, Edward Liverts +3
The time evolution of initially balanced, rapidly rotating models for an isolated disk of highly flattened galaxies of stars is calculated. The method of direct integration of the…
HS 0822+3542 - a new nearby extremely metal-poor galaxy
A. Y. Kniazev, S. A. Pustilnik, J. Masegosa +9
We present the results of spectrophotometry and BVR CCD photometry, as well as integrated HI radio measurements of a new blue compact galaxy (BCG) HS 0822+3542 with extremely low o…
VCC 144 - a star-bursting dwarf galaxy in the Virgo Cluster
N. Brosch, E. Almoznino, L. Hoffman
We describe results of a multi-spectral study of a blue compact dwarf galaxy in Virgo. The object was observed with broad-band and H imaging, UV observations, and radio synthesi…
