My former master student Sofia Maggioni won the 2022 INFN prize “Milla Baldo Ceolin” for the best theses in the field of theoretical physics. Her master thesis was titled “Fully Relativistic Magnetohydrodynamic Simulations of Spinning Massive Black Hole Binaries” and she worked under my supervision and in collaboration with Prof. Monica Colpi and Mr. Federico Cattorini.
The news, in Italian, can be found on the Bicocca news blog.
We submitted a new paper investigating the dynamics of magnetized plasma accreting onto merging supermassive black holes including, for the first time, the effect of misaligned black hole spins.
The purpose of simulations like these is to investigate possible electromagnetic emission that could be generated by these systems. Supermassive black hole mergers are powerful sources of gravitational waves that will be detected by the future LISA mission, but, as simulations like ours show, they could also produce electromagnetic counterparts, that could be detected by future X-ray observatories, such as Athena.
My latest talk at the “April” meeting of the American Physical Society that was held in Washington DC from January 28 to 31 2017 is now available on line on the conference web page. In this talk I presented a short overview of the most important results of our latest paper on “General relativistic magnetohydrodynamic simulations of binary neutron star mergers forming a long-lived neutron star“.
That session included also other interesting talks about neutron star simulations and magnetic fields, and many of those talks can also be downloaded from the APS April meeting web page.
The 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!
NASA Goddard Space Flight Center circulated a press release on my recent paper published on the Astrophysical Journal Letters and titled “General Relativistic Simulations of Magnetized Plasmas around Merging Supermassive Black Holes“. The press release can be found at http://www.nasa.gov/topics/universe/features/black-hole-secrets.html.
NASA circulated a press release on my article published on the Astrophysical Journal Letters: “The Missing Link: Merging Neutron Stars Naturally Produce Jet-like Structures and Can Power Short Gamma-ray Bursts“. The press release can be found here and more video and images can also be found here.
