New Insights into the Quasar Type1/Type2 Dichotomy from Correlations between Quasar Host Orientation and Polarization
B. Borguet, D. Hutsemékers, G. Letawe +2
We investigate correlations between the direction of the optical linear polarization and the orientation of the host galaxy/extended emission for type1 and type2 radio-loud and rad…
Understanding the relations between QSOs and their host galaxies from combined HST imaging and VLT spectroscopy
Y. Letawe, P. Magain, G. Letawe +2
The host galaxies of six nearby QSOs are studied on the basis of high resolution HST optical images and spatially resolved VLT slit spectra. The gas ionization and velocity are map…
Quasar Host Orientation and Polarization: Insights into the Type 1/Type 2 Dichotomy
B. Borguet, D. Hutsemékers, G. Letawe +2
We investigate correlations between the optical linear polarization position angle and the orientation of the host galaxy/extended emission of Type 1 and Type 2 Radio-Loud (RL) and…
Evidence for a Type 1/Type 2 dichotomy in the correlation between quasar optical polarization and host galaxy/extended emission position angles
B. Borguet, D. Hutsemékers, G. Letawe +2
For Seyfert galaxies, the AGN unification model provides a simple and well established explanation of the Type 1/Type 2 dichotomy through orientation based effects. The generalizat…
A deconvolution-based algorithm for crowded field photometry with unknown Point Spread Function
P. Magain, F. Courbin, M. Gillon +4
A new method is presented for determining the Point Spread Function (PSF) of images that lack bright and isolated stars. It is based on the same principles as the MCS (Magain, Cour…
