Seminari


Seminars are organized jointly by the Trieste Astronomical Observatory (INAF/OATS) and the Astronomy Unit of the Physics Dept. of the Trieste University (UNI/TS). They usually take place on Wednesdays at 11:30, in the seminar room (Sala Ovale) of Villa Bazzoni in via Bazzoni 2, TS.

TITLE: Studying Scaling Relations of Galaxy Clusters out to High Redshift


ABSTRACT: Galaxy clusters contain rich information of cosmology and astrophysics. In the past, cluster science was limited by a lack of adequately deep observations in multi-wavelength and was subject to heterogeneous samples with small sizes at low redshift. The situation has been changed due to the recent success of the large mm wavelength surveys—such as the South Pole Telescope (SPT)—that employ the Sunyaev-Zel’dovich Effect (SZE) to identify and study galaxy clusters in their abundance out to the early and distant Universe. Together with the breakthroughs in the area of wide-and-deep optical and NIR surveys, such as the Dark Energy Survey (DES) and the Hyper Suprime-Cam survey, we are able to uniformly study these SZE selected samples. In this talk, I will talk about the results from the SPT and DES with emphasis on various observable to mass scaling relations. I will demonstrate the crucial need for the accurate mass calibration in order to pave a way for cluster science in the future.
