STIS Spectroscopy of PKS 0405-123
G. Williger, S. Heap, R. Weymann +2
We present results for QSO PKS 0405-123 (z=0.574, V=14.9), as part of a STIS Investigation Definition Team (IDT) key project to study weak Ly-alpha forest systems at low z. We dete…
The Evolution of the Lyman Alpha Forest From Redshift 3 to 0
Romeel Davé
I review results obtained from studies of the high-redshift Lyman alpha forest, and present new results from HST/STIS spectra of low-redshift quasars in comparison with cosmologica…
Self-Interacting Dark Matter
Benjamin D. Wandelt, Romeel Dave, Glennys R. Farrar +3
Spergel and Steinhardt have recently proposed the concept of dark matter with strong self-interactions as a means to address numerous discrepancies between observations of dark mat…
Theoretical Modeling of the High Redshift Galaxy Population
David H. Weinberg, Romeel Dave', Jeffrey P. Gardner +2
We review theoretical approaches to the study of galaxy formation, with emphasis on the role of hydrodynamic simulations in modeling the high redshift galaxy population. We present…
Cosmology with the Lyman-alpha Forest
David H. Weinberg, Scott Burles, Rupert A. C. Croft +11
We outline the physical picture of the high-redshift Ly-alpha forest that has emerged from cosmological simulations, describe statistical characteristics of the forest that can be…
