Star Forming Histories and Gas Fractions of Galaxies from z=1-3 (PHIBSS1) & Molecular Gas at the Peak Epoch of Galaxy Formation (PHIBBS2)

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.

Spatially resolved optical and millimetre images of a typical massive galaxy at redshift z=1.1 (5.5 billion years after the Big Bang). The left image was taken with the Hubble Space Telescope. The right image is an overlay of the CO 3-2 emission observed with the PdBI (red/yellow colours) superposed on the I-image (grey). Credits: IRAM/MPE

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.

Results  from the PHIBSS1 (2009-2011) and PHIBBS2 (2013-2017) surveys were published and are available in the data archive for public perusal. For details on the data processing see Tacconi et al. (2010).

The links below provides access to the baseline data products: uv-tables, data cubes, spectra and integrated intensity maps. The README file (PHIBSSprovides a detailed description of the data release. The official PHIBSS1 and PHIBSS2 repositories are at IRAM.
