Cosmology with the
High-Resolution Microwave Sky
Observations of the anisotropies of the cosmic microwave background (CMB)
have provided a solid foundation for the standard cosmological model: a
universe consisting primarily of dark matter, seeded by Gaussian primordial
perturbations and experiencing a relatively recent acceleration in its
expansion. While the Planck satellite has measured large-scale temperature
anisotropies to excellent precision, a wealth of information remains to be
uncovered in CMB polarization and in small-scale secondary anisotropies due
to gravitational lensing and the presence of ionized gas at late-times. I
will review how ongoing and future high-resolution ground-based CMB
experiments will provide valuable information on massive neutrinos, dark
energy and the primordial fluctuations through these new windows, and
additionally cross-examine curious disagreements between early-time and
late-time measurements (e.g. the Hubble tension). I will also present new
results from the Atacama Cosmology Telescope, a ground-based
arcminute-resolution survey of the CMB.

Mathew Madhavacheril is the P. J. E. Peebles Fellow at the Centre for the
Universe, Perimeter Institute. He obtained his PhD from Stony Brook
University and subsequently was a postdoctoral researcher at Princeton
University before starting at Perimeter. He is a data-oriented cosmologist
primarily interested in learning about fundamental physics from the cosmic
microwave background and large-scale structure. He is closely involved with
the ongoing Atacama Cosmology Telescope and upcoming Simons Observatory
surveys.

Introducer and Co-host: Matthew Johnson, Perimeter Institute
Join our final colloquium for the summer next Tuesday, September 1:
Looking for Imprints of Microphysics on Large Scale Structure
with Chanda Prescod-Weinstein, University of New Hampshire

This summer, colloquia and lectures were added to our YouTube channel,
AspenPhysics. Descriptions of both are on our website:
