abstract
We consider the scenario emerging from the dynamics of a generalized $d$-brane in a $(d+1, 1)$ spacetime. The equation of state describing this system is given in terms of the energy density, $\rho$, and pressure, $p$, by the relationship $p = - A/\rho^{\alpha}$, where $A$ is a positive constant and $0 < \alpha \le 1$. We discuss the conditions under which homogeneity arises and show that this equation of state describes the evolution of a universe evolving from a phase dominated by non-relativistic matter to a phase dominated by a cosmological constant via an intermediate period where the effective equation of state is given by $p = \alpha \rho$.

A solid unification of the dark sector
A generalized Chaplygin-type solid unifies dark matter and dark energy via an early pressureless phase transitioning to a late solid phase that supports acceleration and produces distinct low-redshift perturbation signatures.

Hydrodynamic properties in soliton field theory
Soliton formation in complex scalar field theory is framed as sound-mode-induced phase separation, and cylindrical Q-strings are shown to suffer a Rayleigh-Plateau membrane instability that breaks them into spheres.

Quasar cosmology II: joint analyses with Cosmic Microwave Background
Quasar, supernova, BAO, DES, and CMB data are jointly compatible only in an interacting dark-energy model, not in Lambda-CDM, wCDM, or CPL.

A comprehensive numerical study on four categories of holographic dark energy models
Seven holographic dark energy models are constrained with DESI BAO, Planck CMB, and PantheonPlus supernovae; LambdaCDM stays preferred, Ricci dark energy is ruled out, and event-horizon models show large data-set-depe...

Background-level reconstruction of scalar-field potentials from dark-energy histories and comparison with analytic potential families
A background reconstruction maps prescribed ρ_de(z) histories to V(φ) and ranks analytic potentials by Bayesian evidence, with exponential preferred for CPL and shifted-tanh for sign-switching targets.

Masking Black Hole Spin with a Modified Chaplygin Gas Envelope: Radiative Degeneracies from a Phenomenological Three-Region Spacetime
A static black hole embedded in a Modified Chaplygin Gas dark matter envelope can reach a disk radiative efficiency of about 6.5%, mimicking a vacuum Kerr black hole with spin j≈0.3 in continuum-fitting analyses.

Entropic Chaplygin-Gas cosmology and late-universe tension diagnostics
An entropic Chaplygin-gas dark sector can shift fitted H0 values, but the shift and any tension relief depend on supernova calibration and vanish with DES-Dovekie data.

Cosmological and lunar laser ranging constraints on evolving dark energy in a nonminimally coupled curvature-matter gravity model
Nonminimal curvature-matter coupling produces dynamical dark energy consistent with DESI observations and lunar laser ranging equivalence principle constraints.

Resolving the Planck-DESI tension by nonminimally coupled quintessence
Non-minimally coupled quintessence resolves the Planck-DESI Ω_m tension at >3σ while the effective equation of state stays above w=-1 and other tensions on neutrino mass and growth rate are relieved.

Is cosmological data suggesting a nonminimal coupling between matter and gravity?
Fitting a one-parameter modified gravity model to Pantheon+, DES, and BAO data gives mixed evidence: the n=6 version is preferred by information criteria in most combinations, but n=4 and n=10 are often disfavored, an...

Threshold Drop in Accretion Density if Dark Energy is Accreting onto a Supermassive Black Hole
Viscous, rotating accretion of modified Chaplygin gas dark energy onto a supermassive black hole produces a threshold drop in accretion density and a stronger wind.

Three-form dark energy: constraints and multi-probe comparison with $\Lambda$CDM
Three-form dark energy with Gaussian potential is fitted to multi-probe cosmological data and shows mild statistical preference over ΛCDM only in heavily tensioned dataset combinations.
