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.

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 provides a detailed description of the data release. The official PHIBSS and PHIBSS2 repositories are at IRAM.
