TL;DR: In this article, the optical depth of the universe to gamma-rays; tau; and tau coefficient were incorrectly calculated for various redshifts for the baseline model (upper row) and fast evolution (lower row) for individual redshift.

TL;DR: In this paper, the authors investigate the viability of evolutionary models for the light elements Li, Be, and B (LiBeB) and find that models in which the cosmic rays are accelerated mainly out of the average interstellar medium which is increasingly metal-poor at early times significantly underpredict the measured Be abundance of the early Galaxy.

TL;DR: In this article, Stecker et al. determined the intergalactic background light (IBL) as a function of redshift in the far ultraviolet to near infrared range, based purely on data from deep galaxy surveys.

TL;DR: In this article, the authors consider a class of non-renormalizable, Lorentz invariance violating operators that arise in an effective field theory (EFT) description of neutrino sector inspired by Planck-scale physics and quantum gravity models.

TL;DR: In this article, the role of an early episode of massive star formation that would induce a strong destruction of D and a galactic wind was examined and the ability of these models to match the observed local properties of the solar neighborhood such as the gas mass fraction, oxygen abundance, the age-metallicity relation, and the present-day mass function.
