Observational Evidence for Extra Dimensions from Dark Matter
Bo Qin, Ue-Li Pen, Joseph Silk
Recent astronomical observations of systems of dark matter, which have been cited as providing possible support for self-interacting cold dark matter, may provide evidence for the…
Earth-mass dark halos are torn into dark mini-streams by stars
HongSheng Zhao, James E. Taylor, Joseph Silk +1
The promising neutralino dark matter particles generically condense into numerous earth-mass dark halos with smaller substructures suppressed by free streaming\cite{berezinsky}. Th…
Probing the origins of voids with the CMB
L. M. Ord, M. Kunz, H. Mathis +1
In this talk presented at the 5th Rencontres du Vietnam 2004, we discuss our preliminary investigations into voids of primordial origin. We show that if voids in the cold dark matt…
LOFAR as a Probe of the Sources of Cosmological Reionisation
Saleem Zaroubi, Joseph Silk
We propose use of the thickness of the ionisation front as a discriminant between alternative modes of reionisation in the early universe, by stars or by miniquasars. Assuming a ph…
On the excess of power in high resolution CMB experiments
J. M. Diego, P. Vielva, E. Martinez-Gonalez +1
We revisit the possibility that an excess in the CMB power spectrum at small angular scales (CBI, ACBAR) can be due to galaxy clusters (or compact sources in general). We perform a…
A new method for measuring the CMB temperature quadrupole with an accuracy better than cosmic variance
Constantinos Skordis, Joseph Silk
We present a new method for measuring the CMB temperature quadrupole, using large scale CMB polarization. The method exploits the fact that CMB polarization is partially sourced by…
