Author(s): Andrew Cheek, Lucien Heurtier, Yuber F. Perez-Gonzalez, and Jessica Turner If dark matter interacts with the Standard Model only gravitationally its abundance in the universe could be explained by the evaporation of primordial black holes (PBH) through Hawking radiation which “democratically” emits all existing particles. In these two papers, the authors study this scenario in great detail, significantly improving on previous calculations...

Author(s): T. M. C. Abbott et al. (DES Collaboration) A large galaxy survey releases its three-year observations, providing key cosmological-parameter measurements that have double the precision of those previously released. [Phys. Rev. D 105, 023520] Published Thu Jan 13, 2022

Author(s): Massimo D’Elia, Lorenzo Maio, Francesco Sanfilippo, and Alfredo Stanzione The authors perform numerical simulations in lattice QCD for 2+1 flavors in a background magnetic field. In the range studied, the string tension along the field decreases strongly, to a small but nonzero value, while that transverse to the field increases by ~50%. The range of eB ~ 4−9 GeV2 is significantly higher than previous studies. [Phys. Rev. D 104,...

Author(s): Omar Darwish, Simon Foreman, Muntazir M. Abidi, Tobias Baldauf, Blake D. Sherwin, and P. Daniel Meerburg The authors propose a method of constructing the large scale Fourier modes of the cosmic density field, which are very important in cosmology but can, for a variety of reasons be inaccessible, from the correlations they induce, owing to non linear growth among smaller scale modes.

Author(s): Oliver H. E. Philcox The large-scale structure (LSS) is determined by the nonlinear structure growth of the Universe and this information is encoded in higher-order statistics such as the bispectrum (3-point correlation function). Robust inference of parameters from the galaxy bispectrum is much more challenging than for the power spectrum (2-point-function). One major problem is the computationally intensive and expensive handling...

Author(s): V. A. Dommes and M. E. Gusakov The authors formulate dissipative magnetohydrodynamic equations for finite temperature superfluid and superconducting mixtures, accounting for particle diffusion and the possible presence of vortices. They relate phenomenological transport coefficients to mutual friction and momentum transfer rates of the microscopic theory and suggest that this will find wide application in the study of neutron stars...
