Strong Gravity News & Events

Gr@v members Pedro Cunha and Carlos Herdeiro were two of the speakers of the Workshop "Dynamics in Strong Gravity" that took place at the Yukawa Institute for Theoretical Physics, Kyoto, Japan, 1-14 September 2018.

The XI Black Holes Workshop will take place at IST-Lisbon on 17-18 December 2018. The Black Holes Workshops gather researchers working on physical and mathematical problems of black holes, both in its classical and quantum aspects, as well as their connections to general relativity and gravitation, string theory, cosmology, and astrophysics, and stimulate the interaction between all these issues.

The paper "Spontaneous scalarisation of charged black holes", co-authored by Gr@v members C. Herdeiro and E. Radu, together with N. Sanchis-Gual and J. A. Font, from the U. Valencia, was published in September 2018 in Physical Review Letters.

João Rosa was interviewed for Porto Canal's "Mentes que brilham" about his work on stimulated axion decay around primordial black holes as a possible origin for fast radio bursts, recently published in Physical Review Letters. He also gave a related interview to the radio programme "Click" on Antena 1.

In a recent paper "Head on collisions of Proca Stars", [arXiv:1806.07779], by N. Sanchis-Gual et al., head-on collisions of exotic compact objects known as "Proca stars" were studied via fully non linear numerical simulations, with the goal of extracting the gravitational wave templates that such exotic objects could produce.

Watch the presentation movie of the COST Action CA16104 Gravitational waves, black holes and fundamental physics (GWverse), in which Gr@v is involved as part of the core group.

The movie was created at the University of Aveiro (Portugal), written and directed by Carlos Herdeiro, with Design and Graphics by Joana Reis and Ana Sousa and Edited by Pedro Henriques.

The article "Stimulated axion decay in superradiant  clouds around astrophysical black holes" (arXiv:1709.06581), co-authored by Gr@v member João Rosa and Tom Kephart (Vanderbilt University, USA), has been accepted for publication in Physical Review Letters and will be highlighted as one of the PRL Editors' Suggestions (a distinction attributed to about one in six Letters).

The Aveiro University section of the EPS Young Minds, selected the General Relativity course they organised in the Fall term of 2017 at Aveiro U., in collaboration with Gr@v, as a reference event. This course will be highlighted in a poster presentation at the 7th Young Minds Leadership Meeting to take place in Prague in May 2018. Click "Read More" to find a link to the full poster.
