Detection and Fundamental Applications of Individual First Galaxies
Renyue Cen
First galaxies formed within halos of mass M=E7.5-E9 Msun at z=30-40 in the standard cold dark matter (CDM) universe may each display an extended hydrogen 21-cm absorption halo aga…
Where Are the Baryons? III: Non-Equilibrium Effects and Observables
Renyue Cen, Taotao Fang
Numerical simulations of the intergalactic medium have shown that at the present epoch a significant fraction (40-50%) of the baryonic component should be found in the (T~10^6K) Wa…
Where Are the Baryons? II: Feedback Effects
Renyue Cen, Jeremiah P. Ostriker
Numerical simulations of the intergalactic medium have shown that at the present epoch a significant fraction (40-50%) of the baryonic component should be found in the (T~10^6K) Wa…
Very Large H II Regions Around Proto-Clusters of Galaxies During Reionization
Renyue Cen
The physical basis for the belief that the abundant old dwarf galaxies seen in present-day galaxy clusters formed before reionization of the universe is very compelling, because (1…
The Rise of Dwarfs and the Fall of Giants: Galaxy Formation Feedback Signatures in the Halo Satellite Luminosity Function
Asantha Cooray, Renyue Cen
The observed luminosity function (LF) of satellite galaxies shows several interesting features that require a better understanding of gas-thermodynamic processes and feedback effec…
Galactic Wind Effects on the Lyman-alpha Absorption in the Vicinity of Galaxies
Juna A. Kollmeier, Jordi Miralda-Escude, Renyue Cen +1
We present predictions of Ly-alpha forest-galaxy correlations at z=3 from Eulerian simulations that include the effects of galactic winds, driven primarily by supernova explosions.…
