PHIBSS - Star Forming Histories and Gas Fractions of Galaxies from z=1-3


PHIBSS is the 'IRAM Plateau de Bure HIgh-z Blue Sequence Survey'. PHIBSS is a world-wide (France/ Germany/Israel/Italy/Spain/Switzerland/US) collaboration led by Reinhard Genzel (MPE) to detect CO from a large sample of massive main-sequence star forming galaxies at high redshift and produce high-resolution maps of the dynamics and structure of the brightest galaxies detected.

PHIBSS overarching science goals are to measure the baryonic cold gas mass of massive main-sequence star forming galaxies at high redshift and improve understanding of the evolution of their cold gas reservoirs over a cosmic time of 3 Gyr.

PHIBSS first term results (2009-2011) were published in Tacconi et al. 2010 (Nature, 463, 781, 2010) and are now available in the ILPA archive for public perusal. PHIBSS first term data release covers 32 main-sequence galaxies from the DEEP2/AEGIS and BM/BX surveys. The official PHIBSS repository is at IRAM.

For basic details on the data processing see Tacconi et al. (2010). The link above provides access to the baseline data products: uv-tables, data cubes, spectra and integrated intensity maps. The README file provides a detailed description of the data release.

Please do not hesitate to contact Reinhard Genzel and collaborators to inform them about your use of the data for further scientific studies. Peer-reviewed publications that have made use of the data are Genzel et al. MNRAS 407, 2091, 2010, Genzel et al. ApJ 746, 69, 2012, Tacconi et al. ApJ 2013 and Freudlich et al. A&A 2013.

The following acknowledgement is appreciated: "This work made use of PHIBSS 'The Plateau de Bure HIgh-z Blue Sequence Survey' (Tacconi et al. 2010)." An acknowledgment of PHIBSS is welcome if data are used in public presentations.
