Tommaso Ghigna (Oxford U.)  “The quest for CMB B-modes and the challenge of controlling systematic effects”

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

Abstract:   The Cosmic Microwave Background has played a central role for cosmology in the past few decades. From the very first detection of its temperature more than 50 years ago to the measurement of the temperature anisotropy, every step contributed …

Peter Timbie (UW-Madison) “21cm Intensity Mapping: A New Cosmological Tool?”

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

ABSTRACT: The 21 cm line from neutral hydrogen gas has many useful properties for mapping large volumes of the cosmos. These maps will give us a view of the Universe when the first luminous objects formed through gravity - the …

Qing Shilo Xia (Yale) “Hunting for neutrinoless double beta decay with liquid xenon detectors”

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

Abstract:  Liquid xenon (LXe) is employed in a number of current and future detectors for rare event searches. In this talk, I will present the latest results from EXO-200, which searched for neutrinoless double beta decay (0υββ) in Xe-136 between …

Sumit Dahal (Johns Hopkins U) “The Cosmology Large Angular Scale Surveyor: Detector Design and Performance”

HYBRID 50A-5132 (Sessler Conference Room), https://lbnl.zoom.us/j/91782268585 50A-5132

Abstract: The Cosmology Large Angular Scale Surveyor (CLASS) aims to characterize the primordial gravitational waves at the level of tensor-to-scalar ratio of 0.01, and make a cosmic-variance-limited measurement of the optical depth to reionization. CLASS is an array of four …

Taylor Hoyt (University of Chicago) “Using Astrophysical Distance Indicators to Test Standard Cosmology”

Zoom Talk 50A-5132, Berkeley, ca

Abstract: Measurements of the universe's present-day expansion rate, or the Hubble constant (H0), that use a Cepheid variable star calibration of Type Ia supernovae (SNe Ia) are in >4σ disagreement with values predicted by the standard, Lambda cold dark matter …
