Title: Gravitational wave astrophysics: a new era of discovery

Date: Monday, November 5, 2018

Time: 4:00pm – 5:00pm
Location: 472 Willamette Hall

Abstract: Large-scale interferometric detectors including LIGO and Virgo sense gravitational waves: minuscule fluctuations in space-time from the most extreme phenomena in the Universe. The 2017 detection of gravitational waves by LIGO and Virgo in concert with an associated electromagnetic counterpart was a breakthrough in multi-messenger astronomy that confirmed the association between neutron star collisions and short gamma-ray bursts (sGRBs) and yielded new insight into the physical engine driving sGRBs. Future gravitational wave observations have the potential to provide critical insight into key open questions in astrophysics, including the distribution of compact objects in the Universe, the evolution of compact binary systems, galaxy formation, and the explosion mechanism of core-collapse supernovae.

I will present the major outstanding challenges in gravitational wave astrophysics, including computational methods for identifying transient signals in noisy data that contains a high rate of transient noise artifacts. I will discuss the prospects for using joint gravitational wave and electromagnetic observations to maximize the potential of gravitational wave detectors across the frequency spectrum, including third generation ground-based detectors and LISA.

Title: Exploring the dark universe through molecules and nuclei

Date: Monday, October 29, 2018

Time: 4:00pm – 5:00pm
Location: 472 Willamette Hall


Repeated null-results at dark matter experiments targeted at WIMP masses, have resulted in the spotlight shifting to lighter dark matter and more exotic WIMP candidates. In this talk I shall present the rich level structure of molecules and nuclei as a tool to explore MeV scale dark matter and dark forces. I will also present a novel detector concept that supplies energy to dark matter, thus accessing inelastic dark matter parameter space.
