Extrapolating the Evolution of Galaxy Sizes to the Epoch of Reionization
galaxies evolution formation high-redshift cosmology theory
2010/11/16
We use data on the high-redshift evolution of the size distribution and luminosity function of galaxies to constrain the relationship between their star formation eciency and starburst lifetime. Base...
Reionization constraints using Principal Component Analysis

2010/11/12
Using a semi-analytical model developed by Choudhury & Ferrara (2005) we study the observational
constraints on reionization via a principal component analysis (PCA). Assuming
that reionization at z...

Star forming galaxies represent a valuable tracer of cosmic history. Recent observational progress with Hubble Space Telescope has led to the discovery and study of the earliest-known galaxies corresp...
