ESO VLT optical spectroscopy of BL Lacertae objects. III. An extension of the sample
B. Sbarufatti, S. Ciprini, J. Kotilainen +4
We present results of an ongoing program at the ESO VLT for spectroscopy of BL Lac objects lacking a firm redshift estimate and here we report on 15 objects. For 11 sources we conf…
Near-infrared spectroscopy of Seyfert galaxies
J. K. Kotilainen, J. Reunanen, M. A. Prieto
Results from near-infrared 1.5 - 2.5 micron long-slit spectroscopy of 14 nearby Seyfert galaxies are presented.
Black hole masses of BL Lac objects
J. K. Kotilainen, R. Falomo, A. Treves
The correlation between black hole mass M(BH) and the central stellar velocity dispersion sigma in nearby elliptical galaxies affords a novel way to determine M(BH) in active galax…
Near-infrared imaging of the host galaxies of intermediate redshift steep spectrum radio quasars
J. K. Kotilainen, R. Falomo
We present the results of near-infrared H-band (1.65 microns) imaging of 19 steep spectrum radio quasars (SSRQ) in the redshift range 0.5 < z < 1.0. This sample of SSRQs is matched…
Optical imaging of the host galaxies of X-ray selected BL Lacertae objects
R. Falomo, J. K. Kotilainen
We investigate the properties of the host galaxies of X-ray selected (high frequency peaked) BL Lac objects using a large and homogeneous data set of high spatial resolution R-band…
The host galaxies of BL Lac objects in the near--infrared
J. K. Kotilainen, R. Falomo, R. Scarpa
We present the results of near-infrared H band (1.65 microns) imaging of 11 BL Lac objects with redshifts ranging from z = 0.05 to 0.9. We are able to clearly detect the host galax…
