Title: Supernovae from Bounce to Breakout
Host: Robert Svoboda
Room: PHY 285
Time: 4:10 pm
Abstract: Simulations of core-collapse supernovae (CCSNe) experienced consecutive leaps of progress in the last decade. I will summarize exciting results in CCSNe modeling that have informed accurate ab-initio prediction of stellar explosion. I will discuss the joint detectability of correlated neutrinos and gravitational waves from such events, which will illustrate the dynamics of the remnant neutron star, the morphology of the explosion, and global stellar instabilities. I will share late-time neutrino data for 100 axisymmetric simulations; showcase a new, two-dozen model suite of 3D simulations; illustrate an exotic - perhaps not uncommon - joint formation of a black hole with an exploding CCSNe; and finally, tease early simulations that couple core-bounce and explosion to shock breakout.

Title: Quantum Magnetometry in search of Dark Matter
Room: 3024 PSEL
Host: Hsin-Chia Cheng
Abstract: When bosonic DM have an ultra-light mass, they act as a classical, coherent field. In many cases, and specifically in some ALP models, this field has magnetic properties, and it can therefore be measured by quantum magnetometers. The Noble and Alkali Spin Detectors for Ultralight Coherent darK matter (NASDUCK) collaboration, was formed a few years ago in order to measure such DM. I will discuss the two publications of NASDUCK, each using well known techniques in magnetometry, albeit ones that were never used before in DM research. I will also discuss my ongoing work which proposes a new quantum magnetometry method, relying on utilizing quantum noise as an observable for DM research. This new metrological strategy has never been implemented before, even outside DM research, and may prove sensitive to DM models that were previously unreachable.
