Consistent Trees: Gravitationally Consistent Halo Catalogs and Merger Trees for Precision Cosmology

TL;DR: This algorithm is able to robustly measure the self-consistency of halo finders; it is the first to directly measure the uncertainties in halo positions, halo velocities, and the halo mass function for a given halo findinger based on consistency between snapshots in cosmological simulations.
Journal ArticleDOI

Modelling gamma‐ray burst observations by Fermi and MAGIC including attenuation due to diffuse background light

TL;DR: In this paper, a simple phenomenological model for the number and redshift distribution of gamma-ray bursts that can be seen at GeV energies with the Fermi satellite and the MAGIC atmospheric Cherenkov telescope was developed.
Journal ArticleDOI

GeV Gamma-Ray Attenuation and the High-Redshift UV Background

TL;DR: In this paper, the authors present new calculations of the evolving UV background out to the epoch of cosmological reionization and make predictions for the amount of GeV gamma-ray attenuation by electron-positron pair production.
Journal ArticleDOI

Cosmology and 21st-Century Culture

TL;DR: For example, according to as mentioned in this paper, in many traditional societies, no value was higher than maintaining harmony between the way the universe is and the way human beings behave, and this synergy was lost as new scientific discoveries and theories were made and a schism developed between religion and science.
