Cosmology Seminar
Cosmology Seminars are held at on Mondays at 11 am during the academic year, on the 3rd floor Varian conference room. These are more focused and less didactic than the colloquium, and provide a stage for younger researchers to present their work in more detail.
Please contact Risa Wechsler, Daniel Gruen, Josh Meyers, or Kyle Story for more information.
The Connection between Large Scale Structure and the Cosmic Microwave Background

Campus, Varian 355
Speaker
Marcelo Alvarez (UC Berkeley)
Cosmic microwave background (CMB) photons were initially released at recombination, less than half a million years after the big bang. In the nearly 14 billion years since, they have been scattered and lensed by intervening structure, imprinting a complex pattern of additional intensity and polarization anisotropies onto maps of the microwave sky. These CMB maps therefore contain a wealth of information about the large scale structure (LSS) of the universe.
Measuring the Hubble Constant with Gravitational Waves

Location
Campus, Varian 355
Speaker
Hsin-Yu Chen (Harvard)
The first detection of binary neutron star merger by Advanced LIGO-Virgo and the discovery of the optical counterpart allowed for the first independent measurement of Hubble constant with gravitational waves.
