Observational constraints on a nonlinear spinor field quintessence model in an FLRW universe
Abstract In the framework of a spherically symmetric Friedmann–Lemaître–Robertson–Walker (FLRW) spacetime, we construct a quintessence model driven by a nonlinear, massless spinor field in an open-universe scenario. The model parameters are constrained using recent cosmological observations…

Vacuum Cherenkov radiation for nonminimal dimension-5 Lorentz violation
Abstract Vacuum Cherenkov radiation is investigated in the Lorentz-violating Standard-Model Extension for isotropic dim-5 operators $$\hat{m}$$ m ^ and $$\hat{a}^{\mu }$$ a ^ μ in the fermion sector. Both the kinematics and dynamics of this process are studied by analytical and numerical means…

Testing the cosmic distance duality relation using model-independent approach
Abstract In this work, we test the cosmic distance duality relation (CDDR) using the arbitrary redshift pivot Padé-(2,1) expansion methodology developed in Ref Fazzari et al. http://arxiv.org/abs/2509.16196 . This approach allows us to constrain the cosmography parameters and test the CDDR at any…

Optics in spiral dislocation spacetime: torsion as a geometric waveguide and frequency-filtering mechanism
Abstract We present an exact analytical study of null trajectories and scalar wave propagation in a $$(2+1)$$ ( 2 + 1 ) -dimensional spacetime containing a spiral dislocation, a topological defect characterized by torsion in the absence of curvature. For null rays, the torsion parameter $$\beta $$…

Effects of tidal charge on Blandford–Znajek process around braneworld black holes
Abstract The Blandford–Znajek (BZ) process is a pivotal mechanism to efficiently extract the energy from a rotating black hole (BH) via its plasma-filled magnetosphere in relativistic astrophysics. Within the framework of extended BZ monopole expansion, we have studied BZ process in the…

Search for imprints of isovector–scalar mesons and kaon condensation in binary neutron star inspiral gravitational waves
Abstract Gravitational wave signals emitted during the binary neutron star inspiral phase offer a promising avenue for probing stellar internal composition. Isovector–scalar mesons and kaon condensation are thought to play pivotal roles in characterizing asymmetric nuclear matter and constraining…

Quasinormal spectra of a wormhole family: overtone features and a parameter-controlled redshift
Abstract Though investigated extensively in the past, we take a detailed relook at the study of quasinormal modes (QNM) in a known family of wormholes (ultrastatic ( $$g_{00}=-1$$ g 00 = - 1 ), as well as spacetimes with different, non-constant $$g_{00}$$ g 00 ), which includes the familiar…

Quasinormal modes and greybody factors of black holes corrected by nonlinear electrodynamics
Abstract Can models that are degenerate in electromagnetic observations (i.e., having identical shadows) be distinguished by their dynamical behaviors and quantum radiation properties? To address this question, this paper considers a unique charged black hole with logarithmic term corrections in…

Particle background characterization and prediction for the NUCLEUS reactor CE $$\nu $$ ν NS experiment
Abstract NUCLEUS is a cryogenic detection experiment which aims to measure Coherent Elastic Neutrino–Nucleus Scattering (CE $$\nu $$ ν NS) and to search for new physics at the Chooz nuclear power plant in France. This article reports on the prediction of particle-induced backgrounds, especially…

New opportunities for rare charm from $$Z\rightarrow c\bar{c}$$ Z → c c ¯ decays
Abstract We analyze the potential of rare charm decays as probes of new physics at a high-luminosity flavor facility operating at the Z pole, such as the FCC-ee or CEPC. In particular, we identify clean null-test observables in $$D^0 \rightarrow \pi ^+ \pi ^- \nu \bar{\nu }$$ D 0 → π + π - ν ν ¯…

Unifying dark matter and dark energy as a Fermi gas in extra dimensions
Abstract We propose a unified framework for dark matter and dark energy based on the thermodynamic properties of a degenerate, relativistic Fermi gas in a higher-dimensional space-time. Extending the standard equation of state to D-dimensional space-time, we derive analytical expressions for the…

Probing the chronology protection conjecture via scalar quasiresonance
Abstract Hawking’s Chronology Protection Conjecture (CPC) proposes that the laws of physics prevent the formation of time machine. In his original argument, fields near a would-be chronology horizon undergo repeated blueshifts, signaling the onset of instabilities. In this work, we obtain an exact…

First principles quantization of a non-conservative scalar field
Abstract We present the first-principles quantization of a damped scalar field within the framework of classical action principle of non-conservative systems using doubled dynamical variables. We consider a non-conservative potential term constructed to describe a linear damping of the scalar field…

Energetics of accretion disk around black holes in Einstein–Gauss–Bonnet gravity
Abstract We investigate the spacetime geometry and astrophysical properties of a static, spherically symmetric black hole in the context of Einstein–Gauss–Bonnet gravity, characterized by a Gauss–Bonnet coupling constant $$\kappa $$ κ and a non-electromagnetic geometric charge Q. The black hole…

Shadow and quasi-normal modes of Schwarzschild–Hernquist black hole
Abstract In this paper we study the shadow and quasi-normal modes (QNMs) of a black hole (BH) surrounded by a dark matter halo with Hernquist-type density distribution, which was reported in Cardoso et al. (Phys. Rev. D 105(6):L061501, 2022). In astrophysical scenarios, we find that the shadow…

Dymnikova black hole surrounded by quintessence
Abstract The Dymnikova black hole (BH) is a regular solution that interpolates between a de Sitter core near the origin and a Schwarzschild-like behavior at large distances. In this work, we investigate the properties of a Dymnikova BH immersed in a quintessential field, characterized by the state…
