Was reionization complete by z ~ 5-6?
Andrei Mesinger
It is generally taken for granted that reionization has completed by z=6, due to the detection of flux in the Lyman alpha forest at redshifts z<6. However, since reionization is ex…
The Inhomogeneous Ionizing Background Following Reionization
Andrei Mesinger, Steven Furlanetto
We study the spatial fluctuations in the hydrogen ionizing background in the epoch following reionization (z ~ 5--6). The rapid decrease with redshift in the photon mean free path…
Gas in Simulations of High Redshift Galaxies and Minihalos
Smadar Naoz, Rennan Barkana, Andrei Mesinger
We study the gas content of halos in the early universe using high resolution hydrodynamical simulations. We extract from the simulations and also predict based on linear theory th…
Cosmology from the Highly-Redshifted 21 cm Line
Steven Furlanetto, Adam Lidz, Abraham Loeb +26
One of the next decade's most exciting prospects is to explore the cosmic "dark ages," during which the first stars in the Universe formed, with the 21 cm line of neutral hydrogen.…
Astrophysics from the Highly-Redshifted 21 cm Line
Steven Furlanetto, Adam Lidz, Abraham Loeb +26
The cosmic dark ages and the epoch of reionization, during which the first generations of stars and galaxies formed, are among the most compelling frontiers of extragalactic astrop…
