This May, CENTRA postdoc Alex Vano-Vinuales is visiting the SXS group (https://www.black-holes.org/) in TAPIR (http://www.tapir.caltech.edu/) at Caltech in Pasadena, California, US.
He delivered a seminar entitled "Current numerical efforts on free hyperboloidal evolutions" (https://www.caltech.edu/campus-life-events/calendar/tapir-seminar-283), where he talked about the hyperboloidal research currently being carried out at CENTRA. Fruitful interactions are taking place between Alex and some postdocs and students of the SXS group; the idea is to compare signals at infinity obtained with two approaches, Cauchy-characteristic evolution and hyperboloidal.
Alex's stay overlapped with the seminar visit of Rodrigo Panosso Macedo, who had previously been a long term visitor to CENTRA and is also part of the Hyperboloidal Research Network (https://hyperboloid.al/). Apart from more scientific discussions, there was also time to squeeze in a visit to Joshua Tree National Park!
