Thermal instabilities in Active Galactic Nuclei: the case of thin vs. thick ionized media
A. C. Goncalves, S. Collin, A. -M. Dumont
We have studied the thermal instabilities in the context of Active Galactic Nuclei (AGN), addressing the cases of thin and thick (stratified) X-ray illuminated media. For that, we…
Discovery of a bright quasar without a massive host galaxy
Pierre Magain, Geraldine Letawe, Frederic Courbin +4
Quasars are thought to be powered by the infall of matter onto a supermassive black hole at the centre of massive galaxies. As the optical luminosity of quasars exceeds that of the…
Zams Rotational Velocities of be Stars
Juan Zorec, Christophe Martayan, Yves Fremat +2
We show that Be stars belong to a high velocity tail of a single B-type star rotational velocity distribution in the main sequence (MS). We studied 127 galactic field Be stars and…
ALMA and Cosmology
F. Combes
ALMA is a privileged instrument to tackle high redshift galaxies, due to the negative K-correction in the millimeter domain. Many dusty star-forming galaxies, invisible in the opti…
The Galaxy in the cosmological context
F. Combes
A new view on our Galaxy has recently emerged, with large consequences on its formation scenarios. Not only new dwarf satellites have been detected, still orbiting and tidally disr…
New CO observations and simulations of the NGC 4438/NGC 4435 system
B. Vollmer, J Braine, F. Combes +1
NGC 4438 is a highly perturbed spiral with a stellar tidal tail and extraplanar molecular gas, now very HI deficient, crossing the center of the Virgo cluster at high speed. Variou…
