Journal ArticleDOI
Scale dependent three-dimensional charged black holes in linear and non-linear electrodynamics
Ángel Rincón,Ernesto Contreras,Pedro Bargueño,Benjamin Koch,Grigorios Panotopoulos,Alejandro Hernández-Arboleda +5 more
TL;DR: In this article, the scale dependence at the level of the effective action of charged black holes in the Einstein-power-Maxwell theory was studied in 3-dimensional spacetimes without a cosmological constant.
Journal ArticleDOI
Scale-dependent (2+1)-dimensional electrically charged black holes in Einstein-power-Maxwell theory
TL;DR: In this paper, the scale dependence at the level of the effective action of black holes in the presence of non-linear electrodynamics has been studied in terms of the horizon and thermodynamic properties of the classical black holes.
Journal ArticleDOI
Dark matter effect on realistic equation of state in neutron stars
TL;DR: In this article, the relativistic mean field theory was applied to neutron stars assuming that fermionic dark matter is trapped inside the star and interacts directly with neutrons by exchanging standard model Higgs bosons.
Journal ArticleDOI
Warm $\frac{\lambda }{4}\phi ^{4}$ inflationary universe model in light of Planck 2015 results
TL;DR: In this paper, the authors show that warm chaotic inflation characterized by a simple φ 4 φ φ + 4 selfinteraction potential for the inflaton, excluded by current data in standard cold inflation, and by an inflaton decay rate proportional to the temperature, is in agreement with the latest Planck data.
Journal ArticleDOI
GW170817 constraints on the properties of a neutron star in the presence of WIMP dark matter
Abdul Quddus,Grigorios Panotopoulos,Bharat Kumar,Bharat Kumar,Bharat Kumar,Shakeb Ahmad,S. K. Patra,S. K. Patra +7 more
TL;DR: In this paper, the authors considered a relatively light weakly interacting massive particle (WIMP) as a dark matter candidate with properties suggested by the results of the DAMA/LIBRA collaboration, realized for instance within the framework of the Next-to-Minimal Supersymmetric Standard Model.
