Implications for the Cosmic Reionization from the Optical Afterglow Spectrum
The gamma-ray burst (GRB) 050904 at z=6.3 provides the first opportunity of probing the intergalactic medium (IGM) by GRBs at the epoch of the reionization. Here we present a spectral modeling analysis of the optical afterglow spectrum taken by the Subaru Telescope, aiming to constrain the reionization history. The spectrum shows a clear damping wing at wavelengths redward of the Lyman break, a...

متن کاملHow JWST can measure First Light, Reionization and Galaxy Assembly
We summarize the design and performance of the James Webb Space Telescope that is to be launched to an L2 orbit in 2011, and how it is designed, in particular, to study the epochs of First Light, Reionization and Galaxy Assembly.
متن کاملA Semi-Analytic Model for Cosmological Reheating and Reionization Due to the Gravitational Collapse of Structure
We present a semi-analytic model for the thermal and ionization history of the universe at 1000 & z & 3. This model incorporates much of the essential physics included in full-scale hydrodynamical simulations, such as (1) gravitational collapse and virialization; (2) star/quasar formation and subsequent ionizing radiation; (3) heating and cooling; (4) atomic and molecular physics of hydrogen; a...
متن کاملCosmic Reionization Redux
We show that numerical simulations of reionization that resolve the Lyman Limit systems (and, thus, correctly count absorptions of ionizing photons) have converged to about 10% level for 5 < z < 6.2 and are in reasonable agreement (within 10%) with the SDSS data in this redshift interval. The SDSS data thus constraint the redshift of overlap of cosmic Hii regions to zOVL = 6.1 ± 0.15. At higher...
