Bar Instability and Formation Timescale across Toomre’s Q Parameter and Central Mass Concentration: Slow Bar Formation or True Stability
Published 2025-01-01“…Of importance is that, as suggested by cosmological simulations, disk galaxies have a limited time of ~8 Gyr in the Universe’s timeline to evolve secularly, starting when they became physically and kinematically steady to prompt the bar instability. …”

ISSUES OF VALUES IN ANCIENT PHILOSOPHY
Published 2024-12-01“…It is emphasized that, unlike the Pre-Socratics, who focused on studying the natural world and cosmological questions, the philosophers of classical Greece turned their attention to society and the state, considering that a rational (just, ideal) state is the key to personal well-being. …”

Stationary BTZ space-time in Ricci-inverse and $$f({\mathcal {R}})$$ f ( R ) gravity theories
Published 2024-12-01“…We demonstrate that stationary BTZ space-time is a valid solution in this gravity theory, wherein the cosmological constant undergoes modifications due to the coupling constants. …”

Below the Schwinger critical magnetic field value, quantum vacuum and gamma-ray bursts delay
Published 2025-02-01“…As a rough estimate, we show that the time delay τ of gamma-ray bursts (GRB) having traveled through the entire cosmological distances in an average strong magnetic field such as 106 Tesla, reaches an experimentally considerable value of τ=2.4 hours. …”

Simulating High-redshift Galaxies: Enhancing UV Luminosity with Star Formation Efficiency and a Top-heavy IMF
Published 2025-01-01“…To achieve this, we conduct cosmological hydrodynamic zoom-in simulations, modifying baryonic subgrid physics, and post-process our simulation results to confirm the observability of our simulated galaxies. …”

Searching for string bosenovas with gravitational wave detectors
Published 2025-01-01“…This is the first known source of high frequency gravitational waves, unconstrained by cosmological observations. The strain of this gravitational wave can be larger than 10−14 at low frequencies, lasting for longer than typical duration of experiments. …”

Generalising axion-like particle as the curvaton: sourcing primordial density perturbation and non-Gaussianities
Published 2024-10-01“…Abstract We investigate the non-perturbatively generated axion-like particle (ALP) potential, involving fermions in the dark sector that couple to the ALP, in an early universe cosmological inflationary stage with the ALP being a spectator field. …”

Color Confinement, Hadron Dynamics, and Hadron Spectroscopy from Light-Front Holography and Superconformal Algebra
Published 2018-01-01“…I will also discuss the remarkable features of the Poincaré invariant, causal vacuum defined by light-front quantization and its impact on the interpretation of the cosmological constant. AdS/QCD also predicts the analytic form of the nonperturbative running coupling αs(Q2)∝e-Q2/4κ2. …”

ORGANICITY OF THE PHENOMENON OF CULTURE AS AN EXPLICATION OF VITALITY
Published 2019-12-01“…The consequences of such a "non-cosmological" justification of freedom and will, and the assertion of values, that contradict the logic of life, are the global environmental, economic and social crisis of our time. …”

ТHE BEGINNING OF THE WORLD ACCORDING TO HESIODS AS THE BIRTH OF PHILOSOPHICAL ONTOLOGY
Published 2024-12-01“…The attitude of the ancient philosophical tradition to the concept of Chaos, which was problematized even by the pre-Socratics and compared with the famous Orphic cosmologies, is analyzed. In this sense, the image of Chaos in Hesiod can be considered as the first principle of building the world by analogy with the search for arché in later philosophers, as well as in its abstract, idealized form – the initial theoretical model of being and the beginning of ancient ontology. …”
