Alex Ji @alexji.bsky.social · 03/09/2026Vedant Chandra: the Via project will get 0.1 km/s stable velocity precision for streams. If v precision of only 1 km/s, can only see a few very large impacts; but 0.1 km/s resolves 20-30x more impacts reaching to 1e8 Msun halos at infall #KICPDM 100 0
Alex Ji @alexji.bsky.social · 03/09/2026Chandra: Via can cover velocity dispersions for all >3000 Msun dwarf galaxies out to 300 kpc (e.g. 40 Segue 1 stars in one hour), and it will get ~1000 QSOs for the LyA forest from z=3.2-4.1 that can constrain the IGM thermal history #KICPDM 000 0
