Active Galactic Nuclei: fueling and feedback

Dynamical mechanisms are essential to exchange angular momentum in galaxies, 
drive the gas to the center, and fuel the central super-massive black holes. 
While at 100pc scale, the gas is sometimes stalled in nuclear rings, recent observations 
reaching 10pc scale, or 60mas with ALMA, have revealed, within the sphere of influence
of the black hole, smoking gun evidence of fueling. Observations of AGN feedback 
will be described, together with the suspected responsible mechanisms. Molecular 

Dark Energy from Planck to Euclid: degeneracies in the dark sector

We are happy to welcome Valeria Pettorino (CosmoStat, CEA Paris-Saclay) for our colloquium next week. Valeria will talk about "Dark Energy from Planck to Euclid: degeneracies in the dark sector”  in Amphi PGG on Friday, March 6th at 11am. 

You are welcome to distribute this announcement to anyone who might be interested!

APC colloquium

Dear all,

We are very happy to welcome Andrzej M. Szelc (Royal Society University Research Fellow, the University of Manchester) at APC this week.

Andrzej will talk about the "Long- and Short-Baseline Neutrino Oscillation Experiments” (abstract and poster below) in Amphi PGG on Friday, February 7th at 11am.

Title: Long- and Short-Baseline Neutrino Oscillation Experiments  

DESI, unraveling dark energy

I will present the stage-IV Dark Energy Spectroscopic Instrument (DESI). The scientific goals of DESI on dark energy, redshift space distortions and constraints on inflation or neutrino mass will be compared to current measurements and limits set by ongoing experiments, in particular by the SDSS BOSS and eBOSS projects. I will illustrate the construction status of DESI, which is nearing completion, and give the timeline of the five-year survey. The project has successfully observed its first spectroscopic light and is now under commissioning.
