## CHIME: The Canadian Hydrogen Intensity Mapping Experiment

Wednesday Sep 04, 2019
Speaker(s):

CHIME is a new interferometric telescope at radio frequencies 400-800 MHz. The mapping speed (or total statistical power) of CHIME is among the largest of any radio telescope in the world, and the technology powering CHIME could be used to build telescopes which are orders of magnitude more powerful.

## Cosmology and fundamental physics with FRBs

Wednesday Sep 04, 2019
Speaker(s):

FRBs are the only known sources of extragalactic coherent radiation, that show interference phenomena after traveling over cosmological distances. The interferometric probe allows equivalent strain measurements of $h\sim 10^{-26}$, opening new windows for gravitational wave detection, dark matter properties, and emission physics. I describe new directions, theoretical and observational tools, and current and future experiments.

## Weak Gravity Conjecture From Amplitudes’ Positivity

Tuesday Sep 03, 2019
Speaker(s):

I will show how to derive new positivity bounds for scattering amplitudes in theories with a massless graviton in the spectrum in four spacetime dimensions. The bounds imply that extremal black holes are self-repulsive, M/|Q|
