Massive galaxies at z~2 in the COSMOS-WIRCAM Ks-band survey -- H. J. McCracken -- IAP [REPORTE]

jeudi 5 févr. 2009, 15:00 → 16:00 Europe/Paris

Salle Grossetete (LPNHE)

In my talk I will describe a new near-infrared survey of the distant Universe which covers the two-square-degree COSMOS field. Combined with a vast amount of ancillary high-quality multi-wavelength data (over 30 photometric bands) this dataset provides a unique probe of the Universe at z~2, and is currently largest and deepest near-infrared survey. I will present results from a forthcoming paper concerning the abudances and clustering properties of a large sample of passive galaxies at z~2 and I will describe how these results can be interpreted in the context of the halo model of galaxy formation.
