Title: Exploring the cosmic history of galaxies 

Date: Wednesday, January 23rd, 2008 
Time: 12:00 
Venue: Villa Bazzoni (via Bazzoni, 2)

*********************************************************** 
Abstract: 
I will present the latest results obtained by the new UKIDSS Ultra Deep Survey (UDS). I will focus on the cosmological evolution of K-band selected galaxies, with particular emphasis devoted to the most massive sources and to the differential evolution of the populations of passive and star-forming galaxies. Furthermore, by exploiting the large area of the UDS field we investigate the properties of UV-selected galaxies at z~6, comparing the results with the latest predictions of the models of galaxy formation. Finally, I will briefly discuss our latest results on the evolution of dust-enshrouded massive galaxies obtained with the SHADES survey.

Title: Some issues on planet formation theory 

Date: Wednesday, January 30th, 2008 
Time: 12:00 
Venue: Villa Bazzoni (Via Bazzoni, 2)
*********************************************************** 
Abstract: During the last ten years, hundreds of extra-solar planets have been discovered, thus providing us with an ever growing sample of systems to compare our theoretical modeling of the process of planet formation with. Planet formation is a complex phenomenon, which involves several dynamical, fluid dynamical, MHD and chemical processes. While the general picture in which planets form mostly within the circumstellar accretion discs surrounding young stars is generally accepted, a few outstanding issues are still in place. The leading theory of planet formation, called the 'core accretion' model, has been sometimes challenged by the alternative 'gravitational instability' model. In this talk, I will discuss merits and backdraws of these two models, in the light of the results of recent numerical simulations of the dynamics of circumstellar discs. I will finish by discussing the predictions of the core accretion model about the potential for planet formation around extremely low mass stars and brown dwarfs, around which it has been recently claimed to have observed the first extra-solar 'planet' seen in imaging.
