Journal ArticleDOI
Extended gravity cosmography
TL;DR: In this paper, the success and the shortcomings of the ΛCDM model, based on cosmography, are discussed and a review of the model's performance is presented. But the model is not considered as a sort of a model-independent approach to tackle the dark energy/modified gravity problem.
Journal ArticleDOI
Extended Gravity Cosmography
TL;DR: In this paper, a cosmographic approach based on rational Pade and Chebyshev polynomials is proposed to overcome limits of standard cosmography based on Taylor expansion.
Journal ArticleDOI
Do gamma-ray burst measurements provide a useful test of cosmological models?
Narayan Khadka,Orlando Luongo,Orlando Luongo,Orlando Luongo,Marco Muccino,Marco Muccino,Bharat Ratra +6 more
TL;DR: In this article, the authors study eight different gamma-ray burst (GRB) data sets to examine whether current GRB measurements can be used to reliably constrain cosmological model parameters.
Journal ArticleDOI
Kinematic constraints beyond z ≃ 0 using calibrated GRB correlations
TL;DR: In this paper, the dynamics of the universe were revised using high-redshift data from gamma-ray bursts to constrain cosmographic parameters by means of model-independent techniques.
Journal ArticleDOI
Accretion disc luminosity for black holes surrounded by dark matter
Kuantay Boshkayev,Kuantay Boshkayev,Kuantay Boshkayev,A Idrissov,Orlando Luongo,Orlando Luongo,Orlando Luongo,Daniele Malafarina +7 more
TL;DR: In this paper, the authors consider the observational properties of a static black hole space-time immersed in a dark matter envelope and investigate how the modifications to geometry induced by the presence of dark matter affect the luminosity of the black hole's accretion disk.
