Celia Escamilla-Rivera (Instituto de Ciencias Nucleares, Universidad Autonoma de Mexico) and Geovanny Rave (Escamilla’s master’s student) were awarded Honorable Mention in the 2023 Essay Competition of the Gravity Research Foundation for their essay “On primordial gravitational waves in Teleparallel Gravity”, https://arxiv.org/abs/2305.06987
Laurent Freidel (Perimeter Institute for Theoretical Physics, Canada), Jerzy Kowalski-Glikman (University of Wroclaw, Poland), Robert G. Leigh (University of Illinois, USA), and Djordje Minic (Virginia Tech, USA) were awarded Honorable Mention in the 2023 Essay Competition of the Gravity Research Foundation for their essay “On the Inevitable Lightness of Vacuum”, https://arxiv.org/abs/2303.17495
which presents a new understanding of the cosmological constant problem.
Carlos Sopuerta (Institute of Space Sciences (ICE) of the National Spanish, Research Council (CSIC), Bellaterra, Barcelona, Spain), together with his colleagues José Luis Jaramillo (Institut de Mathématiques de Bourgogne (IMB), Université de Bourgogne Franche-Comté, Dijon, France) and Badri Krishnan (Institute of Mathematics, Astrophysics and Particle Phyiscs, Radboud University, Nijmegen, Netherlands), were awarded Honorable Mention in the 2023 Essay Competition of the Gravity Research Foundation for their essay “Universality in Binary Black Hole Dynamics: An Integrability Conjecture”, https://arxiv.org/abs/2305.08554,
where they deepen in the simplicity and universality of the waveform
of a binary black hole coalescence.
Julio Arrechea and Carlos Barceló (Institute of Astrophysics of
Andalusia) have been awarded an Honorable Mention
in the 2023 Gravity Research Foundation Awards for Essays on Gravitation
with their essay titled “Stellar equilibrium on
a physical vacuum soil” (https://arxiv.org/abs/2305.07939). This essay
explores the relevance of the quantum vacuum as a key aspect behind the
existence of new figures of stellar equilibrium.
Congratulations to all of them!
Licia Verde, CA18108 Action participant, has received the prestigious “Rey Jaime I” Spanish award on “Basic Research” in its 2021 edition. Our sincere congratulations!
We are proud to announce that the essay “Quantum Gravity Phenomenology in the Infrared”, (arXiv:2104.00802 [gr-qc]), which contributes to our COST CA18108 Action, has won the second prize in the Gravity Research Foundation essay competition.
Congratulations to the authors! From left to right in the photograph: Laurent Freidel (Perimeter Institute for Theoretical Physics, Canada), Jerzy Kowalski-Glikman (University of Wroclaw, Poland), Robert G. Leigh (University of Illinois, USA), and Djordje Minic (Virginia Tech, USA).

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!
Two Action participants, Celia Escamilla-Rivera (Universidad Autonoma de Mexico, ICN-UNAM) and Diego Rubiera-Garcia (Universidad Complutense de Madrid, Spain), have recently received 2019 IOP Publishing Outstanding Reviewer awards by their work as reviewers for Classical & Quantum Gravity, one of the main journals in the field within the scope of our COST Action CA18108.
With these awards, IOP Publishing recognizes excellence in reviewing, and each year their journal editorial teams select the best reviewers of the year based on the quality, quantity and timeliness of their reviews.
Congratulations to both researchers!
Action participants Prof. Eduardo Guendelman (right photograph) and his PhD student David Benisty (left photograph) have been awarded 2nd prize in the international competition organized by the Gravity Research Foundation, with the paper entitled “Lorentzian Quintessential Inflation”. Their work deals with the vacuum energies in the early and late universe, a relevant subject within the scope of our Action. Our congratulations to both researchers!
