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.

On the later evolution of observationally selected protocluster candidates at $z\,{\gtrsim}\,5$
Simulations show observationally selected protocluster candidates at z ≳ 5 include significant interlopers, undergo 2-6 major mergers, and exhibit stronger clustering than observed, requiring total galaxy mass within 10 cMpc for reliable progenitor identification.

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.
