Chaplygin-gas solutions of f(R) gravity
(World Scientific Publishing, 2016)We explore exact f(R) gravity solutions that mimic Chaplygin-gas inspired CDM cosmology. Starting with the original, generalized and modified Chaplygin gas equations of state, we reconstruct the forms of f(R) Lagrangians. ... -
H.E.S.S. constraints on dark matter annihilations towards the Sculptor and Carina dwarf galaxies
(Elsevier, 2011)The Sculptor and Carina dwarf spheroidal galaxies were observed with the H.E.S.S. Cherenkov telescope array between January 2008 and December 2009. The data sets consist of a total of 11.8 h and 14.8 h of high quality data, ... -
H.E.S.S. observations of the globular clusters NGC 6388 and M15 and search for a dark matter signal
(IOP Publishing, 2011)Observations of the globular clusters (GCs) NGC 6388 and M15 were carried out by the High Energy Stereoscopic System array of Cherenkov telescopes for a live time of 27.2 and 15.2 hr, respectively. No gamma-ray signal is ... -
Search for dark matter annihilation signals from the fornax galaxy cluster with HESS
(IOP Publishing, 2012)The Fornax galaxy cluster was observed with the High Energy Stereoscopic System for a total live time of 14.5 hr, searching for very high energy (VHE; E > 100GeV) γ -rays from dark matter (DM) annihilation. No significant ...
