Cosmology at Low Frequencies: The 21 cm Transition and the High-Redshift Universe (2006)
Furlanetto, Steven, Oh, S. Peng, Briggs, Frank
Observations of the high-redshift Universe with the 21 cm hyperfine line of neutral hydrogen promise to open an entirely new window onto the early phases of cosmic structure formation. Here we review...
21 cm Tomography of the High-Redshift Universe with the Square Kilometer Array (2004)
Furlanetto, Steven, Briggs, Frank
We discuss the prospects for ``tomography'' of the intergalactic medium (IGM) at high redshifts using the 21 cm transition of neutral hydrogen. Existing observational constraints on the epoch of...
Reconciling Damped Ly-alpha Statistics and 21cm Studies at z=0 (2001)
Zwaan, Martin, Briggs, Frank, Verheijen, Marc
Blind 21cm surveys in the local universe have shown that the local HI mass density, Omega_HI, is dominated by luminous, high surface brightness, spiral galaxies. On the other hand, surveys for host...
Zwaan, Martin, Verheijen, Marc, Briggs, Frank
We present a measurement of the HI column density distribution function, f(N), at the present epoch for column densities log N > 20 cm^-2. These high column densities compare to those measured in...
The HI Mass Function of Galaxies from a Deep Survey in the 21cm Line (1997)
Zwaan, Martin, Briggs, Frank, Sprayberry, David, Sorar, Ertu
The HI mass function (HIMF) for galaxies in the local universe is constructed from the results of the Arecibo HI Strip Survey, a blind extragalactic survey in the 21cm line. The survey consists of...
