Gravity Initiative Lunch, Elias Most | Flatiron Institute "Constraints on nuclear physics and electromagnetic precursors from neutron star mergers"
Mon, Dec 2, 2019, 12:30 pm12:30 pm

With the detection of GW170817 we have observed the first multi-messenger gravitational wave signal from two merging neutron stars. This signal carried a multitude of information about the underlying equation of state (EOS) of nuclear matter, which so far is not known for densities above nuclear saturation. In particular it is not known if…

Gravity Initiative Lunch, Elena Giorgi | PGI, "The Teukolsky equations in Kerr-Newman spacetime"
Mon, Nov 25, 2019, 12:30 pm12:30 pm

The Kerr-Newman spacetime is the most general explicit black hole solution, and represents a stationary rotating charged black hole. Its stability to gravitational and electromagnetic perturbations has eluded a proof since the 80s in the black hole perturbation community. As put by Chandrasekhar, "the methods that have proved…

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 pm12:00 pm

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…
