APOLLO: the Apache Point Observatory Lunar Laser-ranging Operation: Instrument Description and First Detections
T. W. Murphy, E. G. Adelberger, J. B. R. Battat +10
A next-generation lunar laser ranging apparatus using the 3.5 m telescope at the Apache Point Observatory in southern New Mexico has begun science operation. APOLLO (the Apache Poi…
The Kast Ground Based UV Spectral Survey of 79 QSOs at Redshift 2 for Lyman Alpha Forest and Metal Absorption
David Tytler, John M. O'Meara, Nao Suzuki +3
We present a moderate resolution (~1.15 Angstroms/pixel) survey of 79 quasars obtained using the Kast spectrograph on the Shane 3m telescope at Lick observatory. The spectra span t…
Cosmological parameters sigma_8, the baryon density, and the UV background intensity from a calibrated measurement of H I Lyman-alpha absorption at z = 1.9
David Tytler, David Kirkman, John M. O'Meara +7
We identify a concordant model for the intergalactic medium (IGM) at redshift z=1.9 that uses popular values for cosmological and astrophysical parameters and accounts for all bary…
