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: Slow quenching in the cores of CLASH+HLS galaxy clusters at 0.2 < z < 0.9


ABSTRACT: With the aim of studying the impact of cluster environment in galaxy evolution, we have quantified the star formation (SF) activity in the inner cores (R/R200 ≤0.3) of 24 massive galaxy clusters at 0.2 ≤ z ≤ 0.9 observed by the Herschel Lensing Survey and the Cluster Lensing and Supernova survey with Hubble. These programmes, covering the rest-frame ultraviolet to far-infrared regimes, have allowed us to accurately characterize stellar mass-limited (M*>10^10 Msun) samples of star-forming cluster members (not)-detected in the mid- and/or far-infrared. Our results depict intermediate-z cluster cores as regions where SF activity is strongly suppressed with respect the field in terms of both the fraction (F) of star-forming galaxies (SFG) and the rate at which they form stars. Our findings favour long time-scale quenching physical processes as the main drivers of SF suppression in the inner cores of clusters since z∼0.9, with shorter time-scale processes being very likely responsible for a fraction of the missing SFG population.
