Biases and Uncertainties in Physical Parameter Estimates of Lyman Break Galaxies from Broad-band Photometry (2008)

Lee, Seong-Kook, Idzi, Rafal, Ferguson, Henry C., Somerville, Rachel S., Wiklind, Tommy, Giavalisco, Mauro

We investigate the biases and uncertainties in estimates of physical parameters of high-redshift Lyman break galaxies (LBGs), such as stellar mass, mean stellar population age, and star formation...

Evolution in the Colors of Lyman-Break Galaxies from Z~4 to Z~3 (2003)

Papovich, Casey, Dickinson, Mark, Ferguson, Henry C., Giavalisco, Mauro, Lotz, Jennifer, Madau, Piero, ...

The integrated colors of distant galaxies provide a means for interpreting the properties of their stellar content. Here, we use rest-frame UV-to-optical colors to constrain the spectral-energy...

The Size Evolution of High Redshift Galaxies (2003)

Ferguson, Henry C., Dickinson, Mark, Giavalisco, Mauro, Kretchmer, Claudia, Ravindranath, Swara, Idzi, Rafal, ...

Hubble Space Telescope images of high-redshift galaxies selected via color and photometric redshifts are used to examine the size and axial-ratio distribution of galaxies as a function of redshift at...

The z ~ 4 Lyman Break Galaxies: Colors and Theoretical Predictions (2003)

Idzi, Rafal, Somerville, Rachel, Papovich, Casey, Ferguson, Henry C., Giavalisco, Mauro, Kretchmer, Claudia, ...

We investigate several fundamental properties of z ~ 4 Lyman-break galaxies by comparing observations with the predictions of a semi-analytic model based on the Cold Dark Matter theory of...
