The Effect of Thermal Neutrino Motion on the Non-linear Cosmological Matter Power Spectrum
TL;DR: In this article, the effect of neutrino thermal velocities has been included in a consistent way, and the effect on the matter power spectrum is found to be significant.

TL;DR: The X-Ray Flash (XRF) is the closest γ-Ray Burst (GRB) or XRF known to date as mentioned in this paper, with a host galaxy at z = 0.1055, and a significant increase and subsequent decrease in the apparent brightness of the host, peaking between 10 and 33 days after the GRB.
Journal ArticleDOI
The velocity field of the local universe from measurements of type ia supernovae
Troels Haugbølle,Steen Hannestad,Bjarne Thomsen,Johan P. U. Fynbo,Jesper Sollerman,Saurabh Jha +5 more
TL;DR: In this article, the velocity flow of the local universe relative to the CMB rest frame is measured based on the Jha, Riess & Kirshner (2007) sample of 133 low redshift type Ia supernovae.
