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!
Group meeting: "State of the art techniques in Strong gravity", 26-28 April 2023
The gravity group in Aveiro is organizing a retreat-type group meeting, with a few guests, designed for a period of concentrated discussion and strategic thinking. The meeting, called "State of the art techniques in Strong gravity", is scheduled for 26-28 April 2023, in Hotel Vouga, São Pedro do Sul, Portugal.
This meeting will be held fully on-site, with no online component.
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.
PRL Editor's suggestion and science news coverage
The paper "Exotic compact objects and the fate of the light ring instability" has been selected as Editor's suggestion in Physical Review Letters (published February 7th 2023) and was also featured in Physics Magazine, an online publication from the American Physical Society (APS) that reports on papers in the Physical Review Journals.
Gravitational Waves from Extreme-Mass-Ratio Systems in Astrophysical Environments
Speaker
Francisco Duque (IST and CENTRA)
Event date
Venue
Hybrid Sala 11.2.21 (Math dpt) and Zoom
Event type
Gravitational waves carry unique information about the compact objects that generate them and the underlying gravitational theory describing them, which has allowed us to test General Relativity and the nature of black holes with unprecedented precision. In addition, they can also bear precious information about the astrophysical environments where binaries coalesce.
Post-Newtonian waveform: a state of the art
Speaker
François Larrouturou (Deutsches Elektronen-Synchrotron DESY)
Event date
Venue
Online (only)
Event type
Analytical predictions of the gravitational waveform (amplitude and phasing) are key ingredients for building the templates used in gravitational detectors.
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!
