A call for a 2-year post-doctoral grant in Strong Gravity, within the research grant Gravitational waves, black holes, and fundamental physics, 2022.04560.PTDC, is open from 1 to 20 August 2023. See attached document for details or the Euraxess announcement here.
The VIII International Meeting of "Casa das Ciências" took place at the University of Aveiro from 17-19 July 2023, with the participation of hundreds of teachers. C. Herdeiro was one of the invited speakers talking about black holes and gravitational waves, with the moderation of M. Zilhão.
On Saturday July 15, part of the group got together, with some younger reinforcements, to celebrate the summer and the ending of the academic year. The result was the least important. Great fun, followed by a tasty seaside lunch to replace (in excess!) the burnt calories.
The VIII scalar field dark matter workshop will take place in Playa del Carmen, Mexico, on 29-30 September 2023. C. Herdeiro is one of the invited speakers.
Boson stars are a remarkable type of self-gravitating soliton, which admits multipolar configurations. The simplest non-spherical stars, but still static, are the dipoles, but are they dynamically stable? In the paper "Self-interacting dipolar boson stars and their dynamics", it is shown self-interactions help make these dipoles dynamically robust.
The 11th School on Astrophysics and Gravitation will take place at Instituto Superior Técnico in Lisbon, from 1-6 September 2023. C. Herdeiro and M. Zilhão are two of the lecturers. More info here.
At the end of June 2023 we have enjoyed the visits of Juan Carlos Degollado (UNAM - Mexico), Nico Sanchis Gual (Valencia - Spain) and Mikaela Carrasco (USFQ - Ecuador). Nine nationalities in this group photo taken on June 28 - science brings people together!
Our group organised the European Einstein Toolkit Meeting 2023, at the University of Aveiro, 19-23 June 2023. We had excellent speakers throughout the week, and everybody had a great time. Next year's meeting should be held in Amsterdam; hope to see everyone there!
In this talk I will review some properties of solutions to the static, spherically symmetric Einstein-Klein-Gordon system for a collection of an arbitrary odd number N of complex scalar fields with an internal U(N) symmetry and no self-interactions known as l-boson stars.
