On the contribution of dwarf galaxies to reionization of the Universe

The Open Journal of Astrophysics
We present estimates of the ultraviolet (UV) and Lyman continuum flux density contributed by galaxies of luminosities from $M_{\rm UV}\approx -25$ to $M_{\rm UV}=-4$ at redshifts $5\leq z\leq 10$ using a galaxy formation model that reproduces properties ...

The Ancient Star Formation History of the Extremely Low-mass Galaxy Leo P: An Emerging Trend of a Post-reionization Pause in Star Formation

The Astrophysical Journal
Isolated, low-mass galaxies provide the opportunity to assess the impact of reionization on their star formation histories (SFHs) without the ambiguity of environmental processes associated with massive host galaxies.

Reconstruction of Cosmological Initial Density Field with Observations from the Epoch of Reionization

The Astrophysical Journal
The initial density distribution provides a basis for understanding the complete evolution of cosmological density fluctuations. While reconstruction in our local Universe exploits the observations of galaxy surveys with large volumes, observations of ...

Simulating Cosmic Reionization at Large Scales I: the Geometry of Reionization

, 2005
We present the first large-scale radiative transfer simulations of cosmic reionization, in a simulation volume of (100/h Mpc)^3, while at the same time capturing the dwarf galaxies which are primarily responsible for reionization. We achieve this by combining the results from extremely large, cosmological, N-body simulations with a new, fast and ...

Constraints on the Galaxy Formation Models during the Epoch of Reionization with High-redshift Observations

The Astrophysical Journal
We use high-resolution N -body dark matter simulations and L-G alaxies semianalytical galaxy formation models to explore the high- z galaxy properties and estimate the budget of ionizing photons.
