Penrose process remains a textbook example of a mechanism for energy extraction from black holes, yet there are many impediments to its practical viability. The longest known problem is that it requires a particle to split into two fragments with very high relative velocity.
Tomohiro Nakamura, a PhD student from Nagoya University is visiting Gr@v until the end of January 2020. Masato Minamisuji, from IST-Lisbon, visted for 8-10 January 2020 for scientific collaboration. In the photo with Taishi Ikeda whose visit overlapped with that of Masato's and Tomohiro's.
The Portuguese Science Foundation (FCT) launched the third edition of the "Individual Call to Scientific Employment Stimulus". The call will open from January 30th to February 26th 2020. This call funds post-doctoral positions at various seniority levels. Our group is open to support good candidates in Strong Gravity, Astrophysics and High Energy Physics. For further information contact the group coordinator C. Herdeiro (herdeiro@ua.pt).
The XII Black Holes workshop took place on 19-20 December 2020, at the University of Minho, in the Azurém Campus, Guimarães. As always, a fast paced, intense and stimulating meeting!
Our group coordinated the "Numerical Relativity and High Energy Physics" IRSES network (2012-2015). Here is a list of the global network meetings organized:
