Irreversibility from Self-Reference: Gradient Flow and an H-Theorem for a Self-Referential Statistical Operator Framework
Lucio Marassi
This paper is a direct companion to arXiv:2605.06705, where the self-referential operator Omega was introduced and the Tsallis index q = alpha + beta was derived as a fixed-point c…
Emergence of Tsallis Statistics from a Self-Referential Nonlinear Operator: A Variational Framework
Lucio Marassi
We develop a variational thermodynamic framework for statistical systems governed by a self-referential nonlinear operator Omega characterized by structural exponents alpha > 0, be…
Constraining H0 in General Dark Energy Models from Sunyaev-Zeldovich/X-ray Technique and Complementary Probes
R. F. L. Holanda, J. V. Cunha, L. Marassi +1
In accelerating dark energy models, the estimates of H0 from Sunyaev-Zel'dovich effect (SZE) and X-ray surface brightness of galaxy clusters may depend on the matter content (Omega…
Formation of Dark Matter Haloes in a Homogeneous Dark Energy Universe
Lucio Marassi
Several independent cosmological tests have shown evidences that the energy density of the Universe is dominated by a dark energy component, which cause the present accelerated exp…
Constraining the Nonextensive Mass Function of Halos from BAO, CMB and X-ray data
L. Marassi, J. V. Cunha, J. A. S. Lima
Clusters of galaxies are the most impressive gravitationally-bound systems in the Universe and its abundance (the cluster mass function) is one important statistics to probe the ma…
Constraining from Sunyaev-Zel'dovich effect, Galaxy Clusters X-ray data, and Baryon Oscillations
J. V. Cunha, L. Marassi, J. A. S. Lima
Estimates of from Sunyaev-Zel'dovich effect (SZE) and X-ray surface brightness of galaxy clusters depends on the underlying cosmology. In the current CDM flat cosmology, a…
