Gr@v member Felipe Freitas will lecture a free course on "Introduction to computer vision with pyTorch". Classes will take place on Fridays (the next class will be April 9th 2021) every two weeks, from 2:30 pm to 4:30 pm. More info below (in Portuguese).
Celebrating the international day of Mathematics, March 14th, which is also Einstein's birthday, C. Herdeiro gave an outreach talk in the Maths Dept. of Aveiro on "Pi and Einstein: from the Universe of Geometry to the Geometry of the Universe". It can be seen here (in Portuguese).
Within the context of the European COST Action GWverse, the community has sumarized the state of the art and propects for the future in a comprehensive roadmap: Black holes, gravitational waves and fundamental physics: a roadmap. The GWverse roadmap, co-authored by our group, has been selected by the Editorial Board of Classical and Quantum Gravity (CQG) as one of the journal's Highlights of 2019-2020.
A “time”-covariant Schrödinger equation is defined for the minisuperspace model of the Reissner–Nordström (RN) black hole, as a “hybrid” between the “intrinsic time” Schrödinger and Wheeler–DeWitt (WDW) equations. To do so, a reduced, regular, and “time(r)”-dependent Hamiltonian density is constructed, without “breaking” the re-parametrization covariance r=f (˜r).
The article "Traversable wormholes in Einstein-Dirac-Maxwell theory", recently published in Phys. Rev. Lett. as Editor's suggestion, co-authered by Gr@v member Eugen Radu, was featured in Physics.
A recent Gr@v co-authored article is ranked #130 in all time media coverage of Phys. Rev. Lett. outputs. Watch here (in English) and here (in Portuguese) video explanations of the work.
The machine learning work by Gr@v member Felipe Freitas for detecting gravitational waves was awarded a prize of US $4000 in QHack 2021, being ranked in the top 20 amongst over 300 submitted projects.
A recent paper co-authored by Gr@v in Physical Review Letters, interpreting GW190521 as a collision of bosonic stars (rather than black holes) was covered in the 17 February 2021 BBC Science Focus issue on dark stars.
Europhysics Letters (EPL) is a reference journal founded in 1986 by the European Physical Society (EPS), the Société Française de Physique (SFP) and its subsidiary EDP Sciences, the Società Italiana di Fisica (SIF) and the Institute of Physics (IOP).
Gr@v members co-author a paper in Physical Review Letters suggesting GW190521 may be a hint of a new dark matter particle.
