Constraining Galaxy Formation Epoch - Age Estimation of High Redshift Galaxies - S. Yi et al. Caltech, USA The galaxy formation epoch (z f ) is an important and unique prod- uct of cosmological models, and thus much e ort has been made to constrain it. The most direct way of constraining z f is to estimate the ages of bright elliptical galaxies at high redshifts arrucately, but it has not been an easy task. ... If we adopt our age estimate, the continuum of this galaxy suggests z f  2 { 3. ...

Artist's concept of a disky galaxy growing rapidly via narrow streams of cold gas. The gas provided by these filaments likely fuels the prodigious star formation activity detected in many of these young, disky, massive galaxies. This process, called "cold-mode accretion," has never been directly observed, but Weinzirl and Jogee's findings of a large percentage of massive, disky star-forming galaxies 10 billion years ago suggests that it played an important role in those galaxies' formation. ...

Many new observational data have been measured in the last years, e.g. by the Infrared Space Observatory in 1995-1998, and interpretation of these spectroscopic data is still in progress. This requires the comparison with data of ``analog materials'' delivered by spectroscopical laboratories. Various terrestrial analogs of cosmic solids have been studied in chemical and physical laboratories. ...
