KNN imputation gives highest photo-z accuracy under ideal random missingness with complete training data, while SAITS is more robust for incomplete training sets and realistic mixed missingness patterns in CSST data.
Green Pea and Blueberry galaxies live in isolated low-density environments with the lowest neighbor counts among compared galaxy populations.
Close major galaxy pairs exhibit 8.8% lower HI gas fractions and 15% higher HI star formation efficiency in S+S systems than mass- and redshift-matched isolated controls.
In TNG50, high-stellar-mass galaxies show shallow inner DM slopes regardless of central or satellite status, low-mass galaxies exhibit diverse profiles with satellites steeper especially if red and in massive hosts, and inner slopes steepen from z~1 to z=0 more strongly in the hydro run.

The Inner Dark-Matter Structure of Galaxies
In TNG50, high-stellar-mass galaxies show shallow inner DM slopes regardless of central or satellite status, low-mass galaxies exhibit diverse profiles with satellites steeper especially if red and in massive hosts, and inner slopes steepen from z~1 to z=0 more strongly in the hydro run.
