What is the True HI Gas Content in Massive Quiescent Galaxies in the Local Universe?
Xiao Li, Cheng Li, Cheng Cheng +3
While massive quiescent galaxies are known to be poor in atomic hydrogen (HI), their true HI content remains poorly constrained due to the limited sensitivity and morphological bia…

Super-Eddington accretion of black holes in early nuclear bursts gives birth to Little Red Dots
Yangyao Chen, Houjun Mo
In a recent paper, Chen et al. developed a framework for modeling the seeding and growth of supermassive black holes (BHs) in the context of CDM cosmogony. Here, we use a set of…

JWST/MIRI reveals the true number density of massive galaxies in the early Universe
Tao Wang, Hanwen Sun, Luwenjia Zhou +13
Early JWST studies reporting an unexpected abundance of massive galaxies at -- challenge galaxy formation models in the CDM framework. Previous stellar mass ($M_\s…
