Strong Gravity News & Events

A call for two 10 months research grants in Strong Gravity/High Energy Physics, for M.Sc. holders enrolled in a doctoral programme at Aveiro University, within the research grant “Testing the Kerr hypothesis with gravitational waves and lensing", PTDC/FIS-AST/3041/2020, is open from 1 to 20 December 2021.  See attached document for details (in Portuguese) or the Euraxess announcement (in Portuguese and English) here.

Nico Sanchis-Gual was one of the 8 selected researchers for a junior grant, nationwide, within 74 applicants in the Physical Sciences panel, in the fourth individual call for scientific employment stimulus, promoted by FCT. Congratulations Nico!

Our group had the pleasure to host the visits of Prof. Tiberiu Harko and Prof. Miguel Angel Sanchis Lozano, who presented stimulating seminars on modified gravity and particle physics/cosmology.

Nuno Santos, a Gr@v Ph.D. student was an invited speaker at the Grav@Zon group meeting. The talk is available in YouTube.

Gravity may be an emergent phenomenon instead of a fundamental force. This may lead to a viable theory for quantum gravity. The basic concepts of emergent gravity will be introduced. It will be shown that the requirement of energy conservation through off-shell process generates a gravity-like force. The necessary conditions for gravity to emerge from QFT will be discussed.

E. Radu was one of the invited plenary speakers of the Tim 20-21 conference, organized by the West University of Timisoara, Romania, on November 11-13, 2021.

The LIGO-Virgo-Kagra collaboration released the data of the O3b science run, announcing 35 new candidate events. The corresponding catalogue, which is co-authored by Gr@v member N. Sanchis-Gual can be found here. See also the nice periodic table type organization of the events here.

The 2021 update of the Stanford/Elsevier author database of the standardized citation indicators, features Gr@v members C. Herdeiro and E. Radu in the career long data and (additionally) P. Cunha and N. Sanchis-Gual in the single year 2020 data. All information and data files available here.

We propose an extension of the $f(R,L_m)$ gravity theory by considering the coupling between matter and geometry in conformal quadratic Weyl gravity, explicitly formulated in the Weyl geometry.
