The BH mass of nearby QSOs: a comparison of the bulge luminosity and virial methods
Marzia Labita, Aldo Treves, Renato Falomo +1
We report on the analysis of the photometric and spectroscopic properties of a sample of 29 low redshift (z<0.6) QSOs for which both HST WFPC2 images and ultraviolet HST FOS spectr…
Ongoing Star Formation in the BL Lacertae object PKS 2005-489
A. Bressan, R. Falomo, J. R. Valdes +1
We present VLT long slit optical spectroscopy of the luminous BL Lacertae object PKS 2005-489. The high signal-to-noise ratio and the good spatial resolution of the data allow us t…
Optical spectroscopy of BL Lacertae objects. Broad lines, companion galaxies and redshift lower limits
B. Sbarufatti, R. Falomo, A. Treves +2
Aims: We present optical spectroscopy of a sample of BL Lac objects, to determine their redshift, to study their broad emission line properties and to characterize their close envi…
ESO-VLT optical spectroscopy of BL Lac objects: II. New redshifts, featureless objects and classification assessments
B. Sbarufatti, A. Treves, R. Falomo +3
We report on ESO Very Large Telescope optical spectroscopy of 42 BL Lacertae objects of unknown redshift. Nuclear emission lines were observed in 12 objects, while for another six…
