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.

This event aims to bring researchers into an immersive experience, where attendees can attend crash-course lectures in the fields of black hole and gravitational physics. The event format encourages active participation and interaction, both during and between lectures, with the aim of kick-starting new projects and collaborations.

Machine learning is quickly becoming a state-of-the-art tool for fundamental scientific research in gravity. This tool has the potential to greatly reduce the computational cost of numerically solving problems in general relativity, and promises to improve our ability to quickly model strong gravitational systems. A series of lectures will focus on the use of machine learning techniques as a research tool in strong gravity.

Additionally, this meeting will focus on the construction and simulation of realistic accretion flows, which are often primary targets in astrophysical observations. The comparison of numerical simulations of these accretion flows with astrophysical data has the potential to constrain the gravitational fields around very compact objects.

This meeting offers an opportunity for attendees to gain a deeper understanding of these exciting and rapidly-evolving fields. 


All aspects of the meeting, such as accommodation, meals, and meeting sessions will take place inside Hotel Vouga, in São Pedro do Sul (Portugal), over a period of three days (26th, 27th and 28th April).

Information about the town:

São Pedro do Sul is a town famous for the thermal baths, which date back to pre-Roman times, but that are still quite popular today. The first King of Portugal, Afonso Henriques, is said to have lived in São Pedro do Sul while healing his injuries from the Battle of Badajoz. This is due to the unique richness of the natural sulphurous mineral water from the thermal baths. This water emerges naturally on the surface at a temperature of 68ºC and is distributed over two thermal spas, Rainha D. Amélia and D. Afonso Henriques, which are open all year round.


Visit to the Roman baths:

There is a scheduled group visit to the Roman thermal baths on the 28th of Abril, which is within walking distance from the Hotel. The visit has no added costs, so everyone is welcomed to join.
