A simulation-calibrated limit on the H i power spectrum from the GMRT Epoch of Reionization experiment
The Giant Metrewave Radio Telescope Epoch of Reionization experiment is an ongoing effort to measure the power spectrum from neutral hydrogen at high redshift. We have previously reported an upper
ETHOS—an effective theory of structure formation: From dark particle physics to the matter distribution of the Universe
We formulate an effective theory of structure formation (ETHOS) that enables cosmological structure formation to be computed in almost any microphysical model of dark matter physics. This framework
Canadian Hydrogen Intensity Mapping Experiment (CHIME) pathfinder
A pathfinder version of CHIME (the Canadian Hydrogen Intensity Mapping Experiment) is currently being commissioned at the Dominion Radio Astrophysical Observatory (DRAO) in Penticton, BC. The
Coaxing cosmic 21 cm fluctuations from the polarized sky using m -mode analysis
In this paper we continue to develop the $m$-mode formalism, a technique for efficient and optimal analysis of wide-field transit radio telescopes, targeted at 21 cm cosmology. We extend this
In this paper, we describe the spherical harmonic transit telescope through the use of a novel formalism for the analysis of transit radio telescopes. This all-sky approach bypasses the curved-sky
The GMRT Epoch of Reionization experiment: a new upper limit on the neutral hydrogen power spectrum at z≈ 8.6
We present a new upper limit to the 21cm power spectrum during the Epoch of Reionization (EoR) which constrains reionization models with an unheated IGM. The GMRT-EoR experiment is an ongoing effort
The CHIME Fast Radio Burst Project: System Overview
The CHIME/FRB backend is described, including the real-time FRB search and detection software pipeline as well as the planned offline analyses, which estimate a CHIME /FRB detection rate of 2-42 FRBs/sky/day normalizing to the rate estimated at 1.4-GHz.
Cosmology of atomic dark matter
While, to ensure successful cosmology, dark matter (DM) must kinematically decouple from the standard model plasma very early in the history of the Universe, it can remain coupled to a bath of "dark
What mass are the smallest protohalos?
We calculate the kinetic-decoupling temperature for weakly interacting massive particles (WIMPs) in supersymmetric (SUSY) and extra dimensional models that can account for the cold-dark-matter
Reheating Effects in the Matter Power Spectrum and Implications for Substructure
The thermal and expansion history of the Universe before big bang nucleosynthesis is unknown. We investigate the evolution of cosmological perturbations through the transition from an early matter
