Nonextensive models for earthquakes.
TLDR
The fragment-asperity interaction model recently introduced by Sotolongo-Costa and Posadas is revisited by considering a different definition for mean values in the context of Tsallis nonextensive statistics and introducing a scale between the earthquake energy and the size of fragment epsilon proportional to r3.
J-PAS: The Javalambre-Physics of the Accelerated Universe Astrophysical Survey
The Javalambre-Physics of the Accelerated Universe Astrophysical Survey (J-PAS) is a narrow band, very wide field Cosmological Survey to be carried out from the Javalambre Observatory in Spain with a…
A parametric model for dark energy
Nonextensivity in geological faults
The Southern Photometric Local Universe Survey (S-PLUS): improved SEDs, morphologies, and redshifts with 12 optical filters
The Southern Photometric Local Universe Survey (S-PLUS) is imaging ∼9300 deg2 of the celestial sphere in 12 optical bands using a dedicated 0.8 m robotic telescope, the T80-South, at the Cerro…
Interpreting cosmological vacuum decay
The cosmological vacuum decay scenario recently proposed by Wang and Meng [Classical Quantum Gravity 22, 283 (2005)] is rediscussed. From thermodynamic arguments it is found that the $ϵ$ parameter…
PROBING COSMOLOGICAL ISOTROPY WITH TYPE Ia SUPERNOVAE
We investigate the validity of the cosmological principle by mapping the cosmological parameters H0 and q0 through the celestial sphere. In our analysis, which is performed in a low-redshift regime…
Testing dark energy beyond the cosmological constant barrier
Although well motivated from theoretical arguments, the cosmological constant \emph{barrier}, i.e., the imposition that the equation-of-state parameter of dark energy ($\omega_x \equiv p_x/\rho_x$)…
Model-independent constraints on the cosmic opacity
We use current measurements of the expansion rate H(z) and cosmic background radiation bounds on the spatial curvature of the Universe to impose cosmological model-independent constraints on cosmic…
Dark Energy and the Angular Size-Redshift Diagram for Milliarcsecond Radio Sources
We investigate observational constraints on the cosmic equation of state from measurements of angular size for a large sample of milliarcsecond compact radio sources. The results are based on a flat…
