The Atacama Cosmology Telescope: Millimeter Observations of a Population of Asteroids or: ACTeroids

The Astrophysical Journal
We present fluxes and light curves for a population of asteroids at millimeter wavelengths, detected by the Atacama Cosmology Telescope (ACT) over 18,000 deg ^2 of the sky using data from 2017 to 2021.

Cosmic microwave background radiation anisotropy induced by cosmic strings

, 1995
We report on a current investigation of the anisotropy pattern induced by cosmic strings on the cosmic microwave background radiation (MBR). We have numerically evolved a network of cosmic strings from a redshift of Z = 100 to the present and calculated ...

WMAP: Fluctuations in the Cosmic Microwave Background

This site discusses the cosmic microwave background, radiation left over from the Big Bang. Particular emphasis is upon tiny fluctuations in the temperature of the radiation, which are believed to reflect fluctuations in the density of matter in the ...

Primordial black holes in non-linear perturbation theory

, 2009
PhDThe thesis begins with a study of the origin of non-linear cosmological fluctuations. In particular, a class of models of multiple field inflation are considered, with specific reference to those cases in which the non-Gaussian correlation functions
