The WEBT BL Lac Campaign 2000
Massimo Villata, Claudia M. Raiteri
We present UBVRI light curves of BL Lacertae from May 2000 to January 2001, obtained by 24 telescopes in 11 countries. More than 15000 observations were performed in that period, w…
The Circum-Galactic Environment of Bright IRAS Galaxies
Y. Krongold, Dultzin-Hacyan, P. Marziani
This paper studies systematically, for the first time, the circumgalactic environment of bright IRAS galaxies as defined by Soifer et al. (1989). While the role of gravitational in…
Balmer Line Variations in the Radio-Loud AGN PG 1512+370
P. Romano, P. Marziani, D. Dultzin-Hacyan
We present spectroscopic observations of the quasar PG~1512+370, covering the Hbeta line spectral range and collected at moderate resolution (2-7 A FWHM) from 1988 to 1996. The obs…
Multiwavelength observations of short time-scale variability in NGC 4151. I. Ultraviolet observations
D. M. Crenshaw et al
We present the results of an intensive ultraviolet monitoring campaign on the Seyfert 1 galaxy NGC 4151, as part of an effort to study its short time-scale variability over a broad…
Multiple High-Velocity Emission-Line Systems in the E+S Pair CPG 29
P. Marziani, W. C. Keel, D. Dultzin--Hacyan +1
A detailed study of the mixed-morphology galaxy pair CPG 29 (Arp 119, VV 347) shows spectacular spectroscopic peculiarities in the southern (spiral) component (Mkn 984) including a…
