ALMA observations of five DSFGs in the Spiderweb protocluster reveal disturbed molecular gas kinematics, field-like gas fractions that are lower in massive/AGN hosts, and declining gas content and sSFR with proximity to the central galaxy.

ALMA maps reveal offset compact CO clouds with subthermal excitation in Mrk 996, yielding a molecular gas mass of a few 10^7 solar masses and evidence for a substantial CO-dark H2 component.
CO observations of the COSMOS-Gr30 group at z~0.7 show average molecular gas contents reduced by 0.5 dex relative to field galaxies, with gas fractions 20-40% of main-sequence values, plus an upper limit on cold gas in the extended ionized structure.

Chaotic Molecular Gas in Five Dusty Star-forming Galaxies in the Spiderweb Protocluster at $z = 2.16$
ALMA observations of five DSFGs in the Spiderweb protocluster reveal disturbed molecular gas kinematics, field-like gas fractions that are lower in massive/AGN hosts, and declining gas content and sSFR with proximity to the central galaxy.

Probing the molecular gas content of galaxies in an over-dense group at z~0.7: a test case for environmental quenching
CO observations of the COSMOS-Gr30 group at z~0.7 show average molecular gas contents reduced by 0.5 dex relative to field galaxies, with gas fractions 20-40% of main-sequence values, plus an upper limit on cold gas in the extended ionized structure.
