SUMMARY:Environmental processing in and around clusters
DESCRIPTION:Environmental processing in and around clusters\nDr. Gianluca C
 astignani\n\nGalaxy clusters are the most massive gravitationally bound st
 ructures in the Universe. They are the sites where exceptional morphologic
 al transformations of galaxies occur, driven by their interactions within 
 the complex cosmic web. Clusters are thus excellent laboratories to study 
 galaxy evolution in extreme regimes. I will present the results of a large
  campaign based on IRAM facilities (30m and NOEMA) and targeting in mm dif
 ferent samples of galaxies in and around clusters. The final goal of the p
 roject is to evaluate the role of dense mega-parsec scale environments in 
 processing cold gas of galaxies. The following samples of galaxies will be
  discussed. i) The largest sample of distant ~30 brightest cluster galaxie
 s observed in CO, over a broad range of redshift (z~0.2-2.6). They are dra
 wn from CLASH, COSMOS, SpARCS, and DES deep fields. ii) The largest sample
  of distant, intermediate redshift z~0.2-0.5, cluster LIRGs (luminous infr
 ared galaxies), which have been observed in CO with the NOEMA interferomet
 er and are drawn from the Herschel Lensing Survey (HLS) and the Local Clus
 ter Substructure Survey (LoCuSS).  iii) I will also present ongoing r
 esults of a large campaign with the aim to evaluate the pre-processing of 
 atomic (HI) and molecular (CO) gas of galaxies before they fall into the c
 luster core. The sample comprises 245 galaxies in cosmological filaments, 
 up to 7 virial radii around Virgo, the benchmark cluster in the local Univ
 erse. The outlined studies reveal a complex scenario, where large-scale st
 ructures have a different impact in regulating the star formation fueling 
 and mass assembly of the considered galaxies, depending on their morpholog
 ical type, location with respect to the cluster core, and redshift.\n&nbsp
