Gravity Seminar: Mikolaj Korzynski

Title: Optical drift effects in general relativity Abstract: I will discuss the redshift and the position drifts in general relativity, i.e. the temporal variations of the redshift and the position on the sky of a ligh…

Master defense by Edgars Karnickis

On Monday June 17, 2024 at 13.00 in Bk2 at Blegdamsvej, Edgars Karnickis will defend his master thesis supervised by David Pereñiguez Rodriguez, and Vitor Cardoso. Censor will be Marta Orselli (University of Perugia).…

Simulating the Future through Science Fiction

Jaime Redondo-Yuste recently was part of the winning team of the PSI 15th Anniversary Reunion Pitch Grant. The event took place at Perimeter Institute for Theoretical Physics, in Waterloo (Canada), while celebrating th…

During the Rijksakademie Open Studios 2024, artist Alexandra Hunts and special guest Professor Vitor Cardoso, an expert in gravitational-wave and black-hole physics from the Niels Bohr Institute in Copenhagen, embarked…

To Infinity and Beyond: A Visit to Caltech

Rodrigo Panosso Macedo was invited to visit Caltech this month, where his research program on a novel geometrical framework and numerical techniques for the field of black hole perturbation theory attracted significant…

Tomás Ortín visits Strong

Professor Tomás Ortín from the Instituto de Física Teórica (Madrid) visited Strong in May. Tomas is an expert on gravity, supergravity and string theory. Besides being a collaborator of the group, working with David…

A strong team visits IHES

Recently, two members of the Strong Group, Gregorio Carullo and Marina De Amicis, traveled to the quaint town of Bures-sur-Yvette, near Paris, to visit the Institut des Hautes Études Scientifiques (IHES). The purpose o…

Eclipse of time: a journey into black holes

Vitor has written a book (Eclipse of time: a journey into black holes, or "Eclipse do tempo: um guia para entrar em buracos negros," in portuguese) on black holes, a journey that starts with the notion of time and…

Strong PhD Days in Aud A

The Strong Group organized a two day PhD event on April 18-19, 2024, which took place in the historic Auditorium A at Blegdamsvej. The program gave voice to 9 of the Strong PhD students, as well as our two artists in…

Marica Minucci to join Strong

Marica Minucci will join the Strong Group as a Marie Skłodowska-Curie Fellow to work on the FundBHspec project: “Fundaments of Black Hole Spectroscopy” in collaboration with Rodrigo Panosso Macedo. This project is…

Searching for ringdown higher modes with a numerical relativity-informed post-merger model:

Searching for ringdown higher modes

Do black holes behave as we expect? Is General Relativity the correct theory of gravity in the dynamical high-curvature regime? Spacetime vibrations, generated when the remnant black hole briefly shakes for a few…

Internships at Strong

Strong is now stronger, with two French students joining us for their Masters. Jamil Assaad joined us from Lyon and is working with Vitor and Rodrigo Panosso Macedo. The project aims to study black hole perturbation…

Uncovering the final steps of black holes’ swing dance

Black holes are attractive objects, often preferring to live in couples. When left alone, these couples (known as “binaries”) pierce through the remainder of their long lives obeying a reassuring routine: they dance…

Einstein Waves: a Strong network

The Strong Group is now part of a European network set to study nonlinear aspects of Einstein equations. The effort is funded by a Marie Curie RISE project: 101131233 — EinsteinWaves. Other nodes in Europe include…

LISA moves into adoption stage

LISA, the Laser Interferometer Space Antenna, has passed a major review with flying colours: the entire concept – from the definition of the overall mission and operations to the space hardware to be built – stood up t…

GWverse: the Action that looked up

In 2017, the European COST Action CA16104 Gravitational waves, black holes and fundamental physics (GWverse) was started, chaired by Prof Cardoso, and linking 3 scientific communities that were largely disjoint: one…

Jann Zosso joins Strong

More than a hundred years after Einstein's prediction of their existence, the gravitational wave revolution in physics has now begun. While almost a hundred events of binary coalescence's have already been observed and…

NBI joins the LIGO Scientific Collaboration

The LIGO Scientific Collaboration was responsible for the discovery of gravitational waves from coalescing black holes in 2015, which granted the founders of the project the Nobel Prize in physics in 2017. Since then…
