A Physical Model of Lyman Alpha Emitters
Vithal Tilvi, Sangeeta Malhotra, James E. Rhoads +4
We present a simple physical model for populating dark matter halos with Lyman Alpha Emiiters(LAEs) and predict the physical properties of LAEs at z~3-7. The central tenet of this…
Can substructure in the Galactic Halo explain the ATIC and PAMELA results?
P. J. Elahi, L. M. Widrow, R. J. Thacker
Recently, ATIC and PAMELA measured an anomalously large flux of leptonic cosmic rays which may arise from dark matter self-annihilation. While the annihilation signal predicted for…
Power spectrum for the small-scale Universe
Lawrence M. Widrow, Pascal J. Elahi, Robert J. Thacker +2
The first objects to arise in a cold dark matter universe present a daunting challenge for models of structure formation. In the ultra small-scale limit, CDM structures form nearly…
