VLT adaptive optics imaging of QSO host galaxies and close environment at z ~2.5: results from a pilot program
R. Falomo, J. K. Kotilainen, R. Scarpa +1
We report ESO-VLT near-infrared adaptive optics imaging of one radio-loud (PKS 0113-283) and two radio-quiet (Q 0045-3337 and Q 0101-337) QSOs at z > 2. In the first case, we are a…
ESO-VLT optical spectroscopy of BL Lac objects: I. new redshifts
B. Sbarufatti, A. Treves, R. Falomo +3
We report redshift measurements for 12 BL Lacertae objects from a program aimed at obtaining high signal to noise (up to ~ 500) optical spectroscopy of a mixed sample of objects. T…
The optical-near-infrared colour of the host galaxies of BL Lacertae objects
J. K. Kotilainen, R. Falomo
We present H-band imaging of 23 low redshift (z < 0.3) BL Lac objects that were previously investigated by us in the R-band. For all the observed objects, the host galaxy is well r…
Blue colours of BL Lac host galaxies
J. K. Kotilainen, R. Falomo
Near-infrared and optical imaging of BL Lac host galaxies is used to investigate their colour properties. We find that the R-H colour and colour gradient distributions of the BL La…
The nature of the mid-infrared population from optical identifications of the ELAIS-S1 sample
F. La Franca, C. Gruppioni, I. Matute +14
We present a multi-wavelength catalog (15 um, R, K-band, 1.4 GHz flux) plus spectroscopic identifications for 406 15 um sources detected in the ELAIS region S1, over the flux densi…
