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…
Some Current Issues in Galaxy Formation
Joseph Silk
I describe recent challenges in hierarchical galaxy formation theory, including the formation of disk galaxies and of ellipticals. Problems with cold dark matter are summarized, an…
