Einstein Toolkit and TCAN Workshops at RIT

This week I participated at two very interesting workshops at the Rochester Institute of Technology: the Einstein Toolkit and the TCAN meeting. I gave a talk on wednesday presenting some applications of my WhiskyMHD code to binary neutron star mergers (below you can find the YouTube video of my talk).

Both workshops were successful and with very interesting discussions about the future of the Einstein Toolkit and our plan for the next year of our TCAN international collaboration funded by NASA. Many young researchers joined both meetings indicating a strong potential growth for the field of numerical relativity applied at astrophysical sources.

Gravitational Waves from Binary Neutron Stars!!!

Today the LIGO and Virgo collaboration announced the first detection of gravitational waves from binary neutron star mergers (GW170817). This was exciting already, but even more exciting was the announcement of the detection of several electromagnetic counterparts, from gamma to radio, and in particular the clear association with a short gamma-ray burst. We finally know what causes short GRBs!

Here you can watch a video from a simulation of a binary neutron star merger by me and my collaborators and that was also featured on Nature in an article describing this new exciting discovery.

All the seminars given on December 13 2016 at the “workshop on Numerical Relativity in matter spacetimes for Gravitational Wave astronomy (NRmGW)” in Valencia (Spain) are now available on YouTube. Below you can watch my talk on “Magnetic Field Effects in Neutron Star Binaries”.

Report on my PRACE project now available on GCS webpage

giacomazzo_grsimstar_01The Gauss Centre for Supercomputing (GCS) has now published online my report on my latest PRACE project “GRSimStar – General Relativistic Simulations of Binary Neutron Star Mergers”. The report is written in a way that can (hopefully) be understood by the general public and includes also a short movie from one of my simulations. Enjoy!

GRMHD Simulations of BNS Mergers with the APR4 EOS

Our paper describing fully general relativistic magnetohydrodynamics simulations of binary neutron stars with the APR4 equation of state has been now published on Classical and Quantum gravity!

With the paper we also published our gravitational wave signals, initial data, and movies.

Public outreach talk by the cWB group in Trento

Today Giovanni Prodi and his collaborators gave an excellent public outreach talk on the discovery of gravitational waves and their important contribution to this amazing result. The video below is in Italian and was filmed at the University of Trento.

Gravitational Waves!

Today the discovery of gravitational waves was finally announced. Below you can find the video of the NSF press conference and a simple video explaining what gravitational waves are 🙂
