Phase space analysis and singularity classification for linearly interacting dark energy models
European Physical Journal C: Particles and Fields, 2020 In this paper, applying the Hartman–Grobman theorem we carry out a qualitative late-time analysis of some unified dark energy-matter Friedmann cosmological models, where the two interact through linear energy exchanges, and the dark energy fluid obeys to

Irreversible thermodynamic description of interacting dark energy - dark matter cosmological models
, 2013 We investigate the interaction between dark energy and dark matter in the framework of irreversible thermodynamics of open systems with matter creation/annihilation.

Accretion onto a static spherically symmetric regular MOG dark compact object
European Physical Journal C: Particles and Fields, 2023 In astrophysics, the process of a massive body acquiring matter is referred to as accretion. The extraction of gravitational energy occurs as a result of the infall.

Cosmological models described by a mixture of van der Waals fluid and dark energy [PDF]
, 2003 The Universe is modeled as a binary mixture whose constituents are described by a van der Waals fluid and by a dark energy density. The dark energy density is considered either as the quintessence or as the Chaplygin gas.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Statistical and Dynamical Decoupling of the IGM from Dark Matter
Advances in Astronomy, 2011 Although the gravitational field in the universe is dominated by dark matter, cosmological observations show that the statistical properties of cosmic baryonic matter are significantly and systematically decoupled from that of the underlying dark matter.

New limit on logotropic unified dark energy models
Physics Letters B, 2017 A unification of dark matter and dark energy in terms of a logotropic perfect dark fluid has recently been proposed, where deviations with respect to the standard ΛCDM model are dependent on a single parameter B.

Test the weak cosmic supervision conjecture in dark matter-black hole system
European Physical Journal C: Particles and Fields, 2023 There is a possibility that the event horizon of a Kerr-like black hole with perfect fluid dark matter (DM) can be destroyed, providing a potential opportunity for understanding the weak cosmic censorship conjecture of black holes.
