The maximum isotropic energy of gamma-ray bursts
J-L. Atteia, V. Heussaff, J. -P. Dezalay +7
The most energetic gamma-ray bursts (GRBs) are remarkable sources releasing huge amounts of energy on short timescales. Their prompt emission, which usually lasts few seconds, is s…
Power law cosmology model comparison with CMB scale information
Isaac Tutusaus, Brahim Lamine, Alain Blanchard +14
Despite the ability of the cosmological concordance model (CDM) to describe the cosmological observations exceedingly well, power law expansion of the Universe scale radius, $R(…
Dark sectors of the Universe: A Euclid survey approach
Isaac Tutusaus, Brahim Lamine, Alain Blanchard +3
In this paper we study the consequences of relaxing the hypothesis of the pressureless nature of the dark matter component when determining constraints on dark energy. To this aim…
Dark-energy dependent test of general relativity at cosmological scales
Yves Zolnierowski, Alain Blanchard
The CDM framework offers a remarkably good description of our universe with a very small number of free parameters, which can be determined with high accuracy from currently ava…
The Epeak-Eiso relation revisited with Fermi GRBs: Resolving a long-standing debate?
V. Heussaff, J-L. Atteia, Y. Zolnierowski
We used a sample of GRBs detected by Fermi and Swift to reanalyze the correlation discovered by Amati et al. (2002) between Epi, the peak energy of the prompt GRB emission, and Eis…
