Are you interested in doing research in topics such as black hole physics/mathematics, gravitational waves, numerical relativity, cosmology and high energy particle physics? Do you have (or are you finishing) a M.Sc. degree in Physics or Maths?
If so, and you would like pursue a PhD at Gr@v, there's a few steps you need to follow.
The warp drive: hyper-fast travel within general relativity
Miguel Alcubierre
Class. Quant. Grav. 11 (1994) L73-L77
The observation of the shadow of the supermassive black hole M87∗ by the Event Horizon Telescope (EHT) is sensitive to the spacetime geometry near the circular photon orbit and beyond, and it thus has the potential to test general relativity in the strong field regime.

Gr@v Journal Clubs for 2021/22 have started. Researchers/students from other groups/institutions wanting to attend (they are online) feel free to contact us.
K-essence is a cosmologically relevant scalar-tensor theory that involves first-order derivative self-interactions, which pass all existing gravitational wave bounds and provides a screening mechanism. In this talk, I will present our results about the effect of this screening mechanism in non-linear stellar oscillations and gravitational collapse by using numerical relativity simulations.
Haroldo Lima Junior, Ph.D. student at the U. Federal do Pará, Brazil, advised by Prof. Luis Crispino, is visiting our group for 6 months (Sep 2021 - Mar 2022), under a CAPES "doutorado sandwich" funding.
Rodrigo Vicente, a Ph.D. student co-advised in our group, successfully defended his Ph.D. thesis on "The Gravity of Classical Fields and its effect on the Dynamics of Gravitational Systems", at IST Lisbon on September 21st 2021. Congratulations Rodrigo!
The COST Advanced School on the "Physics of Dark Matter and Hidden Sectors" will take place in Lund, Sweeden, from October 18-21st 2021. Gr@v members C. Herdeiro, A. Morais and F. Freitas are amongst the invited lecturers.
