    $$\varLambda $$ Λ CDM model against gravity-thermodynamics conjecture: observational constraints after DESI 2024 by N. Shahhoseini, M. Malekjani, A. Khodam-Mohammadi

    Published 2025-01-01
    “…Abstract In the context of the gravity-thermodynamics conjecture based on the Tsallis entropy-area relation, we investigate the standard $$\varLambda $$ Λ CDM cosmology and examine some potential deviations from it. …”

    MAGICS. II. Seed Black Holes Stripped of Their Surrounding Stars Do Not Sink by Yihao Zhou, Diptajyoti Mukherjee, Nianyi Chen, Tiziana Di Matteo, Peter H. Johansson, Antti Rantala, Christian Partmann, Ugo Niccolò Di Carlo, Simeon Bird, Yueying Ni

    Published 2025-01-01
    “…We present the MAGICS-II simulation suite, which consists of six galaxy mergers that result in MBH seed mergers identified in the cosmological simulation ASTRID. With the enhanced resolution (mass resolution: 500 M _⊙ ; softening length: 5 pc), improved subgrid models for the MBH dynamics and accretion, and the accurate regularized gravity integrator included in KETJU, we trace MBH seed dynamics down to 0.1 pc. …”

    Epistemic Roots, Universal Routes and Ontological Roofs of African “Ritual Archives”: Disciplinary Formations in African Thought by Oluwatoyin Vincent Adepoju

    Published 2021-12-01
    “…This is a heuristic rather than an attempt at a definitive distinction and is derived from the relationship between my practical and theoretical investigation of Yoruba epistemology and Falola’s exploration, in “Ritual Archives”, of a particularly strategic aspect of òrìṣà cosmology represented by Esu. The distinction I advance between Yoruba philosophy and òrìṣà cosmology and the effort to map their interrelations is useful in categorizing and critically analyzing various postulates that constitute classical Yoruba thought. …”
