High Energy Physics News & Events
Four new Gr@v Seminars are now online!
The last four sessions of the Gr@v group seminars are now on YouTube in our dedicated channel https://www.youtube.com/@Gravchannel. These include the talks from Raimon Luna (University of Valencia), Stephen Green (Univeristy of Nottingham), Beatrice Bonga (Radboud University) and Visakan Balakumar (Sheffield University).
High Energy Physics Colloquium at the University of Cagliari
On February 23, Gr@v member Lorenzo Annulli gave an invited seminar at the University of Cagliari and INFN - Cagliari Unit, in the beautiful seaside city of Cagliari, Sardinia. The seminar, entitled "The close limit approximation of compact objects: black holes, horizonless bodies and future applications" , focused on black holes, gravitational waves and their physics.
Lorenzo has been hosted by Prof. Mariano Cadoni, Andrea Sanna, Mauro Oi and the HEP Colloquia Organizing Committee; many thanks to all of them!
ARCO Distinguished Guest Lecture
Gr@v member C. Herdeiro inaugurated the ARCO Distinguish Guest Lecture series at the Open University, Israel, on Feb 6th 2023, with a seminar on the "Fate of the Light Ring instability".
European Einstein Toolkit Meeting 2023 in Aveiro
The European Einstein Toolkit Meeting 2023 will be held at the University of Aveiro, hosted by our group, from 19–23 June 2023. More info on the event website.
Discussion on "Audible echoes of symmetry restoration -- a status report"
500
The gr@v paper "Asymptotically flat black holes with scalar hair: a review" reached the landmark of 500 citations in the INSPIRE database. The paper was a 2015 IJMPD highlight also figures in the 10 IJMPD most cited papers in the last 3 years.
Numerical convergence of model Cauchy-Characteristic Extraction and Matching
The detection of gravitational waves is a powerful tool in our quest to deepen our understanding of fundamental physics. To make the most out of this tool, we need to accurately simulate the whole process of gravitational wave emission, propagation and detection by interferometers.
NewFunFiCO kick off meeting
The NewFunFiCO Staff Exchange network had its kick off meeting on January 19th 2023. The meeting was virtual, but it promised very interesting real work and synergies to come in the next four years!
Minimum length scale and quantum black holes
The idea that the Planck length can act as a regulator of UV divergences has inspired various approaches to quantum gravity, but a possibly much larger width for the ground state emerges in the (non-perturbative) quantisation of the Oppenheimer-Snyder model of dust collapse that naturally recovers Bekenstein’s area law.
