GWSkyNet: a low latency annotation pipeline for the identification of gravitational wave candidates for the next observing run
The accurate and rapid identification of gravitational wave candidates is crucial for follow-up observations of electromagnetic emissions. In run O3, the LIGO/Virgo collaboration released 80 Open Public Alerts. However, the rates of retractions and false alarms point to the need for a complementary model that predicts the nature and origin of OPAs in low latency. I will discuss GWSkyNet, a machine-learning algorithm capable of discerning between signals of astrophysical and terrestrial origin.

A long time ago in a pp collision far, far away: searching for displaced vertices at CMS

Neutron-proton capture cross section measurement using the SNO+ detector
Experimental neutrino physics has come a long way since the first detection of antineutrinos in 1956. Significant technical advancements (e.g. lower energy threshold, better energy resolution) have created unique opportunities for other fields of physics, such as nuclear physics. This talk shows how the thermal neutron capture (on proton) cross section was measured using the SNO+ detector. This measurement in SNO+ also paves the way to the first observation of antineutrinos in pure water.

Hybrid Detector: The High Voltage detector with background rejection
SuperCDMS interleaved Z-sensitive Ionization and Phonon(iZIP) detectors have shown great success in discriminating electron recoils and nuclear recoils, while the High Voltage (HV) detectors have reached very low (~ a few eV) energy thresholds by sacrificing that discrimination. This talk focuses on a novel phonon-mediated two-stage silicon detector that retains both an excellent threshold performance of the HV detector and maintain the iZIP-style background discrimination.
