Specific Star Formation Rates
We present results from a study to determine how star formation contributes to galaxy growth since redshift z = 1.5. Using galaxies from the MUnich Near-Infrared Cluster Survey (MUNICS) and the FORS Deep Field (FDF), we investigate the specific star formation rate (SSFR, star formation rate [SFR] per unit galaxy stellar mass) as a function of galaxy stellar mass and redshift. We test the compat...
متن کاملCosmic Star-Formation History
I review some recent progress made in our understanding of galaxy evolution and the cosmic history of star formation. Like bookends, the results obtained from deep ground-based spectroscopy and from the Hubble Deep Field imaging survey put brackets around the intermediate redshift interval, 1 < z < 2, where starbirth probably peaked at a rate 10 times higher than today. The steady decline obser...
متن کاملThe Star-formation History of the Universe
Many authors have attempted to model the star formation history of the universe (eg Cole et al 1994, Pei and Fall 1995) or equivalently the evolution of the starburst galaxy population (eg Franceschini et al 1991, 1994, 1997, Blain and Longair 1993, Pearson and Rowan-Robinson 1996, Guiderdoni et al 1998, Dwek et al 1998, Blain et al 1999). Most of these studies explore a small range of models d...
متن کاملThe Star Formation History of the Universe
Strong constraints on the cosmic star formation history (SFH) have recently been established using ultraviolet and far-infrared measurements, refining the results of numerous measurements over the past decade. Taken together, the most recent and robust data indicate a compellingly consistent picture of the SFH out to redshift z ≈ 6, with especially tight constraints for z < 1. There have also b...
متن کاملThe Star Formation History of IZw18
The star formation history in IZw18 has been inferred from HST/WFPC2 archival data. This is done by comparing the derived V, B–V and V, V–I color-magnitude diagrams and luminosity functions with synthetic ones, based on various sets of stellar evolutionary tracks. At a distance of 10 Mpc, the stars resolved in the field of IZw18 allow for a lookback time up to 1 Gyr. We find that the main body ...
