Primordial Magnetic Field Effects on the CMB and Large-Scale Structure
Published 2010-01-01“…We review the constructed numerical program, which is without approximation, and an improvement over the approach used in a number of previous works for studying the effect of the PMF on the cosmological perturbations. We demonstrate how the PMF is an important cosmological physical process on small scales. …”

Smooth Crossing of wΛ=−1 Line in a Single Scalar Field Model
Published 2009-01-01“…Smooth double crossing of the phantom divide line wΛ=−1 has been found possible with a single minimally coupled scalar field for the most simple form of generalized k-essence cosmological model, in the presence of background cold dark matter. …”

The Unity of Space in Kant’s Pre-Critical Philosophy
Published 2022-03-01“…On the view presented herein, Kant’s early account of the unity of space is deeply rooted in his pre-critical cosmological views. In particular, I argue that Kant sees the unity of space as grounded in the cosmological unity of the world of substances, which is itself rooted in the divine conservation of all substances in relations of mutual causal dependence. …”

Striking a Chord with Spectral Sirens: Multiple Features in the Compact Binary Population Correlate with H0
Published 2025-01-01“…For the first time using real data, we show that all of these features carry cosmological information and that the peak near ∼32 M _⊙ consistently correlates with H _0 most strongly. …”

Dynamics of Generalized Tachyon Field in Teleparallel Gravity
Published 2015-01-01“…In contrast with tachyonic teleparallel dark energy model that has no scaling attractors, here we find some scaling attractors which means that the cosmological coincidence problem can be alleviated. Scaling attractors are presented for both interacting and noninteracting dark energy and dark matter cases.…”

Quasinormal modes and GUP-corrected Hawking radiation of BTZ black holes within modified gravity frameworks
Published 2025-02-01“…This paper aims to explore the quasinormal modes (QNMs) and effective potential profiles of massless and rotating BTZ black holes within the frameworks of f(R) and Ricci-Inverse (RI) modified gravity theories, which, while producing similar space-time structures, exhibit variations due to distinct cosmological constants, Λm. We derive wave equations for these black hole perturbations and analyze the behavior of the effective potential Veff(r) under different values of mass m, cosmological constant Λm, and modified gravity parameters α1, α2, β1, β2, and γ. …”

P-v Criticality of a Specific Black Hole in f(R) Gravity Coupled with Yang-Mills Field
Published 2018-01-01“…In the extended phase space, we treat the cosmological constant as a thermodynamic pressure. After we study the various thermodynamical quantities, we show that the thermodynamic properties of the SBH behave as a Van der Waals liquid-gas system at the critical points and there is a first-order phase transition between small-large SBH.…”
