SDSS J124602.54+011318.8: A Highly Luminous Optical Transient at z=0.385
D. E. Vanden Berk, B. C. Lee, B. C. Wilhite +13
We report the discovery of a highly luminous optical transient (OT), SDSS J124602.54+011318.8, associated with a galaxy at a redshift of 0.385. In this paper we consider the possib…
Direct Detection of Warm Dark Matter in the X-ray
K. Abazajian, G. M. Fuller, W. H. Tucker
We point out a serendipitous link between warm dark matter (WDM) models for structure formation on the one hand and the high sensitivity energy range (1-10 keV) for x-ray photon de…
Testing the Cosmic Coincidence Problem and the Nature of Dark Energy
Neal Dalal, Kevork Abazajian, Elizabeth Jenkins +1
Dark energy models which alter the relative scaling behavior of dark energy and matter could provide a natural solution to the cosmic coincidence problem - why the densities of dar…
Sterile Neutrino Hot, Warm, and Cold Dark Matter
K. Abazajian, G. M. Fuller, M. Patel
We calculate the incoherent resonant and non-resonant scattering production of sterile neutrinos in the early universe. We find ranges of sterile neutrino masses, vacuum mixing ang…
