Historic release of the PAU Survey of galaxies and stars

[LifeIsStrange]

Apparently the PAU Survey has been released yesterday, making it the first photometric gen 3.5 survey to be published.
In terms of field of view versus deepness it aims the unique spot of being the largest current photometric survey to be maximally deep (versus decaps or panstarrs that maximize field of view or transient astronomy)
Being the photometric survey with the most color filters ever (40) its redshift accuracy is so high that it blurs the boundary between photometric and spectroscopic redshift estimation, reaching spectroscopic accuracy while being photometric (note that a somewhat similar approach is the one from SPHEREx)

The PAU Survey (PAUS) will provide completed fluxed limited accurate redshift and spectral energy distribution information for millions of galaxies (and stars) to a depth and area never explored before

a 100 deg2 PAUS will provide 3 million redshifts to iAB>22.5 (30 times more than currently available)

PAUS will be a few magnitudes deeper (over 10 times denser) than current completed large area flux limited surveys (such as Gamma) and 10 times larger than current completed deep flux limited surveys (such as VVDS/VIPERS/Deep2)

This breakthrough survey should allow record high cosmological constraints e.g. on the hubble constant
Phys org says:

The release is detailed in two articles published in the Monthly Notices of the Royal Astronomical Society: one measuring distances and another one on calibration of the PAUS data.

While I have found the study about calibration, I am unable to find the survey on distance measurement, I suppose it has not yet been published.

In the coming months, the team will also present an ongoing study on galaxy clustering and intrinsic galaxy shape alignments, contributing to a deeper understanding of how our universe formed and evolved.

Anyway this is something to look forward until Euclid DR1 this december that will mark the true advent of stage IV cosmological surveys (next generation) (even though technically erosita and DESI and LOFAR are the first ones, they are also the most shallow yet and the most niches)
