Gravity Initiative Lunch, Barak Zackay | IAS "Detecting Gravitational Waves With Disparate Detector Responses: Two New Binary Black Hole Mergers"

Mon, Nov 4, 2019, 12:00 pm

Abstract:
I will describe our continuing work for extracting the most of the LIGO-VIRGO data.
In this talk, I will discuss the process that was used to characterize the impact of non-Gaussian phenomena (so called 'Glitches')
I will then discuss the process that exploited the found properties in order to rank candidates based on one detector alone.
I will then discuss how these candidates are then verified using very little information in the less sensitive detector.
Using this, we found two new events. One (GW170817A) is the highest mass event reported to date.
The other (GWC170402) was also very interesting, as there are some solid signs for the expression of higher modes, but a full coherent GR solution that explains the signal is still lacking.

Last, I will discuss the implications of this method for the future analysis of the ongoing third observing run of the LIGO-VIRGO data.
