Action participants receive prize by the journal Universe within its Best Papers Awards 2015-2021
Action participants Diego Rubiera-García (UCM, Madrid, left photograph) and Gonzalo Olmo (IFIC, Valencia, right photograph) are among the winners of the Universe 2021 Best Paper Awards. The journal has selected their paper
Nonsingular Black Holes in ƒ (R) Theories
By: Gonzalo J. Olmo and Diego Rubiera-Garcia
Universe 2015, 1(2), 173–185
as one of the three winning papers, after a thorough evaluation of the originality and significance of the papers, citations, and downloads.
The authors explain about their work:
“The paper Nonsingular Black Holes in ƒ(R) Theories studies the structure of a family of static, spherically symmetric space-times generated by an anisotropic fluid and governed by a quadratic ƒ(R) theory. We found solutions that represent black holes with the central singularity replaced by a finite size wormhole, and showed that time-like geodesics and null geodesics with nonzero angular momentum never reach the wormhole throat due to an infinite potential barrier. For null radial geodesics, it takes an infinite affine time to reach the wormhole. This means that the resulting space-time is geodesically complete and, therefore, nonsingular despite the generic existence of curvature divergences at the wormhole throat.”
Our congratulations to both researchers!
DSR20 online meeting
It’s now 20 years since the first Doubly Special Relativity papers appeared on ArXiv. Several research groups have worked on DSR-relativistic models, leading to significant progress, but some grey areas remain on the conceptual side and additional phenomenological avenues are much needed. The meeting “DSR20” (an online meeting, using zoom) intends to be an opportunity for an exchange of ideas on these matters. DSR20 will be held from december 14 to december 16 and it will be scheduled so to allow colleagues in different parts of the world to attend at least some of the sessions.
