Author(s): Jan M. Pawlowski and Jan Tränkle The authors derive black hole solutions to the quantum equations of motions (e.o.m.) in the framework of asymptotically safe gravity, which is based on the functional renormalization group approach to quantum gravity, After deriving the quantum effective action from multigraviton correlation functions with full momentum dependence and solving numerically the resulting quantum e.o.m., they identify significant...

Author(s): S. Bocquet et al. (The DES and SPT Collaborations) In these two papers, the authors use mock maps to establish a method for studying the abundance and calibrating the weak-lensing based mass of galaxy clusters. They set up a likelihood function, thus obtaining cosmological constraints from a sample of 1,005 clusters detected with the South Pole Telescope, in combination with further cluster data from the Dark Energy Survey, the Wide...

Author(s): Shohei Saga and David Alonso Using the Fast Radio Burst (FRB) dispersion measure as a distance proxy, the paper aims to map three-dimensional FRB distribution and clustering. It further investigates their clustering anisotropy, including relativistic effects, thus paving the way for anisotropy measurements with the Square Kilometer Array. [Phys. Rev.

Author(s): Silvia Mollerach and Esteban Roulet The authors study in thorough detail the possibility that a dominant fraction of ultra-high energy cosmic rays (above 5 EeV) stems from the nearby radio galaxy Centaurus A. They provide remarkably comprehensive and meticulous predictions for the energy spectrum, the measured chemical composition, and anisotropy of the cosmic radiation and show that the influence of the extragalactic and Galactic magnetic...

Author(s): Tung X. Tran, Sarah R. Geller, Benjamin V. Lehmann, and David I. Kaiser An asteroid-mass primordial black hole flying near a planet could perturb the planet’s orbit by a detectable amount. [Phys. Rev. D 110, 063533] Published Tue Sep 17, 2024

Author(s): Giovanni Maria Tomaselli, Thomas F. M. Spieksma, and Gianfranco Bertone Gravitational-wave signals from black hole mergers could reveal the presence of “gravitational atoms”—black holes surrounded by clouds of axions or other light bosons.
