PHIBSS

PHIBSS (Plateau de Bure High-z Blue Sequence Survey) was a survey managed/coordinated by Institut de radioastronomie millimétrique (IRAM), to study star formation and gas fractions, specifically carbon monoxide, of galaxies in the z=1 to z=3 range. It produced to produce high-resolution maps of galaxies in the star formation main sequence with both optical and millimeter images. Observations were carried out on the Plateau de Bure Interferometer (PdBI) from 2008 to 2012 and various results were published beginning in 2009. PHIBSS2 is a successor covering more survey fields and redshifts, its observations carried out on the Northern Extended Millimeter Array (NOEMA, the upgraded PdBI) from 2014 to 2017.
