Gravity Seminar in Southampton, UK

This month I was very honored to be invited to two seminar talks in the UK. The first one being in the University of Southampton, where I gave a talk as part of their Gravity Seminar series. My talk was based on my recent publication, Second release of the CoRe database of binary neutron star merger waveforms from one of my previous posts. I mai... Read more

AstroCoffee Seminar in Frankfurt, Germany

Before the holidays, I had the opportunity to give a talk for the AstroCoffee Seminar series in Frankfurt. In this talk, I presented the black-hole–neutron star ringdown waveform model from my latest publication Phys. Rev. D 107, 084026. During my visit, I had the chance to have interesting discussions with the group in addition to possible coll... Read more

Invited speaker at the European Einstein Toolkit Meeting 2023 in Aveiro, Portugal

This week I was very happy to attend the European Einstein Toolkit Meeting 2023 in Aveiro, Portugal as an invited speaker. My talk was based on my recent publication, Second release of the CoRe database of binary neutron star merger waveforms from one of my previous posts. You can find the slides of the presentation here. In my talk I also of... Read more

DPG Spring Meeting of the Matter and Cosmos Section (SMuK) 2023 in Dresden, Germany

I was finally able to attend the annual DPG meeting in person after last year’s online modality due to the pandemic. This year it was in the beautiful city of Dresden. The talk I presented during this meeting was on my recent publication, Numerical-relativity-informed effective-one-body model for black-hole–neutron-star mergers with higher modes... Read more

Numerical Relativity informed EOB model for BHNS mergers

In 2212.03909 we present the first effective-one-body (EOB) model for generic-spins quasi-circular black-hole–neutron-star (BHNS) inspiral-merger-ringdown gravitational waveforms (GWs). Our model is based on a new numerical-relativity (NR) informed expression of the BH remnant and its ringdown. It reproduces the NR $(\ell,m)=(2,2)$ waveform with... Read more
