seminars

The standard Seminar series is organized jointly by the Trieste Astronomical Observatory (INAF/OATS) and the Astronomy Unit of the Physics Dept. of the Trieste University (UNI/TS).
Standard seminars usually take place on Wednesdays at 15:00, in the seminar room of Villa Bazzoni, via Bazzoni 2.

The Joint Colloquia series is organized by ICTP, INAF/OATS, SISSA, and UNI/TS.
Joint Colloquia usually take place on Thursdays at 15:00, either in Villa Bazzoni, at ICTP or at SISSA.

Seminars are organized by:

Andrea Biviano, biviano AT oats.inaf.it
Gabriele Cescutti, cescutti AT oats.inaf.it
Valentina D'Odorico, dodorico AT oats.inaf.it
Marco Fulle, fulle AT oats.inaf.it

Title: Galaxy groups and cosmic feedback
Date: Thursday, September 16th, 2010
Time: 15:00
Venue: Villa Bazzoni

***********************************************************
Abstract: The hot intergalactic medium seen in many groups preserves a record of elements ejected by group galaxies during their evolution, and its structure appears to have been modified by the poorly understood "feedback" processes which limit the cooling of baryons. In this talk, I will discuss how a study of the properties of galaxy groups can be used to advance our understanding of feedback.

Title: Clustering constrains on black hole evolution
Date: Wednesday, November 24th, 2010
Time: 15:00
Venue: Villa Bazzoni

***********************************************************
Abstract: Clustering measurements has become one of the leading tools in cosmology and theories of galaxy formation. In this work, we use clustering measurements to constrain viable models of quasar activation and black hole evolution. In particular, at high redshifts, observations indicate that models with *short* time delays between the triggering of the quasar and the peak of activity are preferred. Such a fast phase of early accretion points to the possibility of either massive black hole seeds, super-Eddington growth, or both. At low redshifts, we find a rather strong clustering signal at all luminosities. These measurements select models that place faint quasars in very massive dark matter haloes. These type of studies will hopefully play an important role at guiding the next generation of galaxy formation models.
