The Fractal Geometry of the Cosmic Web and Its Formation by Jose Gaite

“…The cosmic web structure is studied with the concepts and methods of fractal geometry, employing the adhesion model of cosmological dynamics as a basic reference. The structures of matter clusters and cosmic voids in cosmological N-body simulations or the Sloan Digital Sky Survey are elucidated by means of multifractal geometry. …”

Instability of Cauchy horizon induced by the graviton mass by Lu Chen, Shun Jiang

“…Massive gravitons are typically introduced to address cosmological issues such as dark energy. In the context of considering massless scalar field perturbations in a charged static black hole, our paper explores the impact of graviton mass on the stability of the Cauchy horizon. …”

The Unity of Space in Kant’s Pre-Critical Philosophy by Dai Heide

“…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. …”

Primordial Magnetic Field Effects on the CMB and Large-Scale Structure by Dai G. Yamazaki, Kiyotomo Ichiki, Toshitaka Kajino, Grant J. Mathews

“…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. …”

Quasinormal modes and GUP-corrected Hawking radiation of BTZ black holes within modified gravity frameworks by Faizuddin Ahmed, Ahmad Al-Badawi, İzzet Sakallı, Abdelmalek Bouzenada

“…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. …”
