History of Star Formation in the Universe
The cosmic history of star formation is briefly reviewed, starting with the Milky Way and then discussing observations relevant to the closed box and hierarchical build-up models. Observations of local star formation are reviewed for comparison. The halo globular clusters appear to have formed in about the same way as today’s clusters, with the same IMF and stellar densities, and with a larger ...
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 کاملPrimordial Star Forming Regions in a CDM Universe
We developed a three–dimensional 2–level hierarchical cosmological code with a realistic and robust treatment of multi–species non–equilibrium ionization and radiative cooling processes, and use it to investigate primordial star forming regions that originate from high–σ perturbations in a standard CDM dominated cosmology. We find it is possible to produce gravitationally bound and cooled struc...
متن کاملThe history of star formation in a Λ-CDM universe
Employing hydrodynamic simulations of structure formation in a ΛCDM cosmology, we study the history of cosmic star formation from the “dark ages” at redshift z ∼ 20 to the present. In addition to gravity and ordinary hydrodynamics, our model includes radiative heating and cooling of gas, star formation, supernova feedback, and galactic winds. By making use of a comprehensive set of simulations ...
