Data Science in Radio Cosmology
Speaker(s): Richard Shaw

In recent decades probing for the subtle indications of new physics in
experimental data has become increasingly difficult. The datasets have gotten
much bigger, the experiments more complex, and the signals ever smaller. Success
stories, like LIGO and Kepler, require a sophisticat... read more

Probing Dark Energy with the Canadian Hydrogen Intensity Mapping Experiment (CHIME)
Speaker(s): Richard Shaw
Abstract: CHIME will use the 21cm emission line of neutral hydrogen to map large-scale structure between redshifts of 0.8 and 2.5. By measuring BAO we will place constraints on the dark energy equation of state as it begins to dominate the expansion of the Universe, particularly at redshifts poorly probed ... read more

Constraining Primordial Magnetism
Speaker(s): Richard Shaw
Abstract: Primodial magnetic fields are a potentially interesting origin for cosmic magnetism. Such fields can leave an interesting signal not only in the CMB temperature and polarization, but in structure at low redshift, contributing to the matter power spectrum and SZ effect at small scales. I will talk ab... read more
