A metallicity-spin temperature relation in damped Lyman-$\alpha$ systems (2009)
Kanekar, Nissim, Smette, Alain, Briggs, Frank H., Chengalur, Jayaram N.
We report evidence for an anti-correlation between spin temperature $T_s$ and metallicity [Z/H], detected at $3.6 \sigma$ significance in a sample of 26 damped Lyman-$\alpha$ absorbers (DLAs) at...
The HI gas content of galaxies around Abell 370, a galaxy cluster at z = 0.37 (2009)
Lah, Philip, Pracy, Michael B., Chengalur, Jayaram N., Briggs, Frank H., Colless, Matthew, De Propris, Roberto, ...
We used observations from the Giant Metrewave Radio Telescope to measure the atomic hydrogen gas content of 324 galaxies around the galaxy cluster Abell 370 at a redshift of z = 0.37 (a look-back...
A GPU based real-time software correlation system for the Murchison Widefield Array prototype (2009)
Wayth, Randall B., Greenhill, Lincoln J., Briggs, Frank H.
Modern graphics processing units (GPUs) are inexpensive commodity hardware that offer Tflop/s theoretical computing capacity. GPUs are well suited to many compute-intensive tasks including digital...
The Murchison Widefield Array: Design Overview (2009)
Lonsdale, Colin J., Cappallo, Roger J., Morales, Miguel F., Briggs, Frank H., Benkevitch, Leonid, Bowman, Judd D., ...
The Murchison Widefield Array (MWA) is a dipole-based aperture array synthesis telescope designed to operate in the 80-300 MHz frequency range. It is capable of a wide range of science...
The H i Column Density Distribution Function at z = 0: the Connection to Damped Ly Statistics (2007)
Martin A. Zwaan, Frank H. Briggs
We present a measurement of the H i column density distribution function [f(N HI)] at the present epoch for column densities> 10 20 cm 2. These high column densities compare to those measured in...

The HI content of star-forming galaxies at z = 0.24 (2007)
Lah, Philip, Chengalur, Jayaram N., Briggs, Frank H., Colless, Matthew, De Propris, Roberto, Pracy, Michael B., ...
We use observations from the Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen gas content of star-forming galaxies at z = 0.24 (i.e. a look-backtime of ~3 Gyr). The sample of...
