Local density field, cosmic web environment, and galaxy type measurements for COSMOS galaxies are now available for download.
Our proposal "Completing the legacy of UltraVISTA" on COSMOS has been accepted. In the next 3 years, the VISTA telescope will image the COSMOS field (1.5 on 1.5 degrees) to its final depth in J, H, and Ks. It will finally reach equal depth across the whole field in these filters. In three years time, we will be able to reach 26, 25.7, and 25.3 AB magnitudes (5-sigma) in J, H, and Ks, respectively. This will double the area on COSMOS at this depth and will be an important step for better measurements and the identification of high redshift galaxies.
The COSMOS2015 catalogue combines the >30 band photometry and SED fits (photometric redshifts, stellar masses, SFRs, etc) of half a million sources up to z=6 spread over the 2 square-degrees of COSMOS. In particular, it uses the new UltraVISTA images, as well as the Spitzer SPLASH photometry! The paper by Laigle et al. (2016) explaining the catalog can be found on the arXiv now: http://arxiv.org/abs/1604.02350 The catalog can be downloaded via anonymous FTP.
The VIMOS Ultra Deep Survey (VUDS) is a deep spectroscopic survey targeting 10,000 galaxies in the redshift range 2
UltraVISTA is an Ultra Deep, near-infrared survey with ESO's VISTA surveys telescope. Over the course of 5 years, UltraVISTA is imaging the COSMOS field in 5 bands (Y, J, H, Ks, NB118) and therefore represents a key survey on COSMOS. The 3rd data release (DR3) is now public and can be downloaded on the ESO archive web-page.
zCOSMOS (PI Simon Lilly, ESO Large Programme 175.A-0839) is a large redshift survey undertaken in the COSMOS field using the VIMOS spectrograph. About 600 hours were awarded to this Large Programme, which was executed between 2005 and 2010. This new release completes the zCOSMOS-bright survey and includes 20689 wavelength calibrated 1-d spectra and associated 5×5 arcsecond image cut-outs for each target.
The James Clerk Maxwell Telescope, now owned and operated by the East Asian Core Observatories Association (EACOA) has recently announced its large legacy programs it will embark on between the end of 2015 to January of 2019, dedicating half of the observatory's time and resources through several collaborative large projects. Two of these projects focus on observations of the COSMOS field.
Members of the COSMOS team were recently awarded Keck time (10 nights through NASA and 4 nights through Caltech) to begin a program designed to systematically measure the galaxy color-redshift relation, in preparation for the upcoming dark energy missions WFIRST and Euclid.
