Initial work began at the University of Massachusetts, Amherst and the Five College Astronomy Department in 2013, to exploit the all-sky sub-mm capabilities of the Planck satellite to search for lensed starburst candidates as a part of a Bachelor student summer project led by Min Yun and Ryan Cybulski for Kevin Harrington.
Large Millimeter Telescope Observations (Mexico) in early 2014 led to successful follow-up campaigns between 2015-2021 with APEX, IRAM30m, and GBT to confirm the redshifts of the sample and characterize the global properties of about 25 objects (UBonn PhD work of Kevin Harrington). Between 2015-2020 data obtained from the VLA, HST and ALMA enabled then UMass PhD student Patrick Kamieneski to publish initial lens models for the majority of the targets and characterize the intrinsic source properties for the first time in our group.
Independent efforts led by Brenda Frye at the University of Arizona, and collaborators, began to merge with the UMass group around 2017, asboth efforts joined forces soon after, leading to the PASSAGES collaboration.
Between 2019-2024 the team grew twice in size to form the core team, including current members who were then pursuing similar efforts.
Currently the collaboration consists of about 30 members affiliated to 20 locations in 11 different countries including: U.S.A., Mexico, Canada, Chile, France, Spain, Sweden, Netherlands, Australia, China
