PC1643+4631A,B: The Lyman-Alpha Forest at the Edge of Coherence
Caitlin M. Casey, Christopher D. Impey, Catherine E. Petry +2
This is the first measurement and detection of coherence in the intergalactic medium (IGM) at substantially high redshift (z~3.8) and on large physical scales (~2.5 h^-1 Mpc). We p…
The Flux Auto- and Cross-Correlation of the Lyman-alpha Forest. I. Spectroscopy of QSO Pairs with Arcminute Separations and Similar Redshifts
Andrew R. Marble, Kristoffer A. Eriksen, Chris D. Impey +2
The Lyman-alpha forest has opened a new redshift regime for cosmological investigation. At z > 2 it provides a unique probe of cosmic geometry and an independent constraint on dark…
21-cm synthesis observations of VIRGOHI 21 - a possible dark galaxy in the Virgo Cluster
Robert Minchin, Jonathan Davies, Michael Disney +10
Many observations indicate that dark matter dominates the extra-galactic Universe, yet no totally dark structure of galactic proportions has ever been convincingly identified. Prev…
An HST/WFPC2 Snapshot Survey of 2MASS-Selected Red QSOs
Andrew R. Marble, Dean C. Hines, Gary D. Schmidt +5
Using simple infrared color selection, 2MASS has found a large number of red, previously unidentified, radio-quiet QSOs. Although missed by UV/optical surveys, the 2MASS QSOs have…
