Group: Galaxies and Cosmology
At moment I am involved in two main projects:
Herschel Virgo Cluster Survey (HeViCS)
HeViCS is an approved open time key program for the ESA Herschel Space Observatory (Pilbratt et al. 2010). It has been awarded 286 h of observing time in parallel mode with PACS (Poglitsch et al. 2010) at 100 and 160 micron and SPIRE (Griffin et al. 2010) at 250, 350 and 500 micron. We will map four 4X4 sq deg regions of the cluster down to the 250 micron confusion limit of ~ 1 MJy/sr.
The primary HeViCS science goals include the detection of dust in the inter-galactic medium, the extent of cold dust in the outskirts of galaxies, the FIR LFs, the complete spectral energy distributions (SEDs) of galaxies, the dust content of dwarf ellipticals and irregulars and a detailed analysis of the dust content of early type galaxies (for further details see HeViCS).
Herschel Fornax Cluster Survey (HeFoCS)
HeFoCS is an ESA Herschel Space Observatory (Pilbratt et al. 2010) Open Time Project. The project was awarded 31 h of observing time in parallel mode using PACS (Poglitsch et al. 2010) at 100 and 160 micron, and SPIRE (Griffin et al. 2010) at 250, 350 and 500 micron. Pre-Herschel comparable surveys describing the far-infrared properties of nearby bright galaxies in both cluster and field have been described by Soifer et al. (1987), Doyon & Joseph (1989, IRAS), Tuffs et al. (2002, ISO), Draine et al. (2007, Spitzer). Davies et al. (2012) have presented Herschel observations of the bright galaxies in the Virgo cluster.
