Refracted Gravity Solutions from Small to Large Scales
Valentina Cesare
If visible matter alone is present in the Universe, general relativity (GR) and its Newtonian weak field limit (WFL) cannot explain several pieces of evidence, from the largest to…
The MPI + CUDA Gaia AVU-GSR Parallel Solver Toward Next-generation Exascale Infrastructures
Valentina Cesare, Ugo Becciani, Alberto Vecchiato +4
We ported to the GPU with CUDA the Astrometric Verification Unit-Global Sphere Reconstruction (AVU-GSR) Parallel Solver developed for the ESA Gaia mission, by optimizing a previous…
Dark Coincidences: Small-Scale Solutions with Refracted Gravity and MOND
Valentina Cesare
General relativity and its Newtonian weak field limit are not sufficient to explain the observed phenomenology in the Universe, from the formation of large-scale structures to the…
The Gaia AVU-GSR parallel solver: preliminary studies of a LSQR-based application in perspective of exascale systems
Valentina Cesare, Ugo Becciani, Alberto Vecchiato +6
The Gaia Astrometric Verification Unit-Global Sphere Reconstruction (AVU-GSR) Parallel Solver aims to find the astrometric parameters for 10 stars in the Milky Way, the a…
The dynamics of three nearby E0 galaxies in refracted gravity
Valentina Cesare, Antonaldo Diaferio, Titos Matsakos
We tested whether refracted gravity, a theory of modified gravity that describes the dynamics of galaxies without the aid of dark matter, can model the dynamics of the three massiv…
Dark matters on the scale of galaxies
Ivan de Martino, Sankha S. Chakrabarty, Valentina Cesare +3
The cold dark matter model successfully explains both the emergence and evolution of cosmic structures on large scales and, when we include a cosmological constant, the properties…
Dynamics of DiskMass Survey galaxies in refracted gravity
Valentina Cesare, Antonaldo Diaferio, Titos Matsakos +1
We test if Refracted Gravity (RG) can describe the dynamics of disk galaxies without resorting to dark matter. RG is a classical theory of gravity where the standard Poisson equati…
