Strong Gravity News & Events
Carolina Benone's PhD exam
Carolina Benone successfully defended her PhD thesis "Scalar fields in black hole spacetimes and analogues". The exam took place in U. Federal do Pará, in Belém, Brazil, on July 14th 2017. The thesis was supervised by Luis Crispino (UFPa) and Gr@v member C. Herdeiro. Congratulations Carolina!
Strong Gravity Universe in Azores
Group members P. Cunha and C. Herdeiro were two of the participants in the "Strong Gravity Universe" workshop, in S. Miguel island, Azores. This meeting was co-sponsored by the GWVerse COST action and StronGrHEP RISE network.
Gr@v research in "90 segundos de Ciência"
"90 seconds of Ciencia" is a daily programme of the National Public Radio, Antena 1. Hear in this link the contribution of Gr@v researchers to this excellent show that makes accessible to a larger audience the research made in Portugal, across all fields of knowledge.
TeV-scale gravity at the LHC, and the way forward in an era lacking significant excesses

Abstract: The hierarchy problem and the irreconcilability of quantum mechanics and general relativity are two of the most frustrating problems that the Standard Model fails to solve. The existence of extra dimensions, however, would provide the much awaited solutions. If extra dimensions exist and push the Planck scale down to the TeV range, signatures of extra dimensions could be found at the Large Hadron Collider in Geneva, Switzerland. Results of TeV-scale gravity searches with the ATLAS and CMS detectors at 13 TeV are summarized, and outlook is provided on the best way forward in the absence of discoveries.
Numerical data and Mathematica notebooks for quasi-Kerr hairy black holes
Here, the numerical data described in Fig. 4 of the paper "Kerr black holes with synchronised hair: an analytic model and dynamical formation", arXiv:1706.06597, together with an explanatory pdf file and two Mathematica notebooks, is made available for public use.
The data consists of four solutions of Kerr black holes with scalar hair and six solutions of Kerr black holes with Proca hair. These families of solutions were first presented in the papers:

Abstract: We study wormhole solutions obtained via applying dualities and complexifications to the vacuum Weyl metrics generated by massive rods and by point masses. The most interesting finding are wormholes with locally flat geometry supported by rings of negative energy.
