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…

Large-Scale Alignments of Quasar Polarization Vectors: Evidence at Cosmological Scales for Very Light Pseudoscalar Particles Mixing with Photons?

D. Hutsemekers, A. Payez, R. Cabanac +4

Based on a sample of 355 quasars with significant optical polarization, we found that quasar polarization vectors are not randomly oriented over the sky as naturally expected. The…

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…

On the potential of extrasolar planet transit surveys

M. Gillon, F. Courbin, P. Magain +1

We analyse the respective benefits and drawbacks of ground-based and space-based transit surveys for extrasolar planets. Based on simple but realistic assumptions about the fractio…
