Evolution of Neutral Gas at High Redshift -- Implications for the Epoch of Galaxy Formation
L. J. Storrie-Lombardi, R. G. McMahon, M. J. Irwin
Though observationally rare, damped Lya absorption systems dominate the mass density of neutral gas in the Universe. Eleven high redshift damped Lya systems covering 2.8<z<4.4 were…
APM z>4 QSO Survey: Distribution and Evolution of High Column Density HI Absorbers
L. J. Storrie-Lombardi, M. J. Irwin, R. G. McMahon
Eleven candidate damped Lya absorption systems were identified in 27 spectra of the quasars from the APM z>4 survey covering the redshift range 2.8<z(abs)<4.4 (8 with z(abs)>3.5).…
APM z>4 QSO Survey: Spectra and Intervening Absorption Systems
L. J. Storrie-Lombardi, R. G. McMahon, M. J. Irwin +1
The APM multicolor survey for bright z > 4 objects, covering 2500 deg^2 of sky to m(R)~19, resulted in the discovery of thirty-one quasars with z > 4. High signal-to-noise optical…
