Measuring the Primordial Deuterium Abundance During the Cosmic Dark Ages
Kris Sigurdson, Steven R. Furlanetto
We discuss how measurements of fluctuations in the absorption of cosmic microwave background (CMB) photons by neutral gas during the cosmic dark ages, at redshifts z ~ 7--200, coul…
Cosmic 21-cm Delensing of Microwave Background Polarization and the Minimum Detectable Energy Scale of Inflation
Kris Sigurdson, Asantha Cooray
The curl (B) modes of cosmic microwave background (CMB) polarization anisotropies are a unique probe of the primordial background of inflationary gravitational waves (IGWs). Unfort…
How Dark is 'Dark'? Electromagnetic Interactions in the Dark Sector
Kris Sigurdson
We review the physical and cosmological consequences of two possible electromagnetic couplings to the dark sector: (i) a neutral lightest dark-matter particle (LDP) with nonzero el…
Statistical Imprints of SZ Effects in the Cosmic Microwave Background
Asantha Cooray, Daniel Baumann, Kris Sigurdson
We review several aspects of the Sunyaev-Zel'dovich (SZ) effect associated with the large scale baryon distribution and its characteristic signatures in the statistics of cosmic mi…
The shapes of dark matter dominated dwarf spheroidal stellar density profiles
Kris Sigurdson, Neil Turok
A Bayesian likelihood analysis of the stellar density profile shapes of several dark matter dominated Galactic dwarf spheroidal galaxies (dSphs) has been completed. This analysis i…
CMB Analysis of Boomerang & Maxima & the Cosmic Parameters {Omega_tot,Omega_b h^2,Omega_cdm h^2,Omega_Lambda,n_s}
J. R. Bond, P. Ade, A. Balbi +40
We show how estimates of parameters characterizing inflation-based theories of structure formation localized over the past year when large scale structure (LSS) information from ga…
