Unbiased surveys of dust-enshrouded galaxies using ALMA

Astrophysics of Galaxies 2023-05-25 v1

Abstract

The ALMA lensing cluster survey (ALCS) is a 96-hr large program dedicated to uncovering and characterizing intrinsically faint continuum sources and line emitters with the assistance of gravitational lensing. All 33 cluster fields were selected from HST/Spitzer treasury programs including CLASH, Hubble Frontier Fields, and RELICS, which also have Herschel and Chandra coverages. The total sky area surveyed reaches \sim133 arcmin2^2 down to a depth of \sim60 μ\muJy beam1^{-1} (1σ\sigma) at 1.2 mm, yielding 141 secure blind detections of continuum sources and additional 39 sources aided by priors. We present scientific motivation, survey design, the status of spectroscopy follow-up observations, and number counts down to \sim7 μ\muJy. Synergies with JWST are also discussed.
