Strongly interacting matter in extreme magnetic fields
Prabal Adhikari, Martin Ammon, Sidney S. Avancini +58
Magnetic fields are ubiquitous across different physical systems of current interest; from the early Universe, compact astrophysical objects and heavy-ion collisions to condensed m…
Lie Symmetries for the Shallow Water Magnetohydrodynamics Equations in a Rotating Reference Frame
Andronikos Paliathanasis, Amlan Halder
We perform a detailed Lie symmetry analysis for the hyperbolic system of partial differential equations that describe the one-dimensional Shallow Water magnetohydrodynamics equatio…
TOI-4504: Exceptionally large Transit Timing Variations induced by two resonant warm gas giants in a three planet system
Michaela Vítková, Rafael Brahm, Trifon Trifonov +24
We present a joint analysis of TTVs and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known transit…
Linearization of Newton's second law
Andronikos Paliathanasis
The geometric linearization of nonlinear differential equation is a robust method for the construction of analytic solutions. The method is related to the existence of Lie symmetri…
Explicit Spectral Analysis for Operators Representing the unitary group and its Lie algebra through the Metaplectic Representation and Weyl Quantization
Fabián Belmonte, Giuseppe de Nittis
In this article we compute and analyze the spectrum of operators defined by the metaplectic representation on the unitary group or operators defined by the corr…
On static and rotating decoupled black holes without inner horizons
Pablo Leon, B. Mishra, Y. Gomez-Leyton +1
Through gravitational decoupling using the extended minimal geometric deformation, a new family of static and rotating ``hairy'' black holes is provided. The background of these mo…
Background-dependent and classical correspondences between and gravity
Cheng Wu, Xin Ren, Yuhang Yang +2
and gravity are based on fundamentally different geometric frameworks, yet they exhibit many similar properties. This article provides a comprehensive summary and com…
Some optical properties of rotating wormhole in Bopp-Podolsky electrodynamics
Muhammad Ali Raza, Francisco Tello-Ortiz, M. Zubair +1
In this work, we consider a static wormhole in Bopp-Podolsky electrodynamics and convert it into its rotating counterpart by reducing it into Morris-Thorne form. We further study t…
The First Spin-Orbit Obliquity of an M dwarf/brown dwarf System: An eccentric and aligned TOI-2119 b
Lauren Doyle, Caleb I. Cañas, Jessica E. Libby-Roberts +15
We report the first instance of an M dwarf/brown dwarf obliquity measurement for the TOI-2119 system using the Rossiter-McLaughlin effect. TOI-2119 b is a transiting brown dwarf or…
Interacting phantom dark energy: new accelerating scaling attractors
Sudip Halder, S. D. Odintsov, Supriya Pan +2
We perform a detailed investigation of interacting phantom cosmology, by applying the powerful method of dynamical system analysis. We consider two well-studied interaction forms,…
Modified gravity from Weyl connection and the extension
Gerasimos Kouniatalis, Emmanuel N. Saridakis
We use Weyl connection and Weyl geometry in order to construct novel modified gravitational theories. In the simplest case where one uses only the Weyl-connection Ricci scalar as a…
FIMP Dark Matter in bulk viscous non-standard cosmologies
Esteban González, Carlos Maldonado, N. Stefanía Mite +1
In this paper, we revisit the extension of the classical non-standard cosmological model in which dissipative processes are considered through a bulk viscous term in the new field…
The Equivalence Principle is NOT a Noether Symmetry
Andronikos Paliathanasis
The connection between the Equivalence Principle and Noether's theorem was discussed in S. Capozziello and C. Ferrara, Int. J. Geom. Meth. Mod. Phys. 21, 2440014 (2024). However, i…
Holographic Boundary Conformal Field Theory within Horndeski Gravity
Fabiano F. Santos, Behnam Pourhassan, Emmanuel N. Saridakis +3
We investigate entanglement islands and the Page curve in the framework of Horndeski gravity on a Karch-Randall braneworld background. In particular, treating the holographic bound…
ALMA-IMF XVIII: The assembly of a star cluster: Dense NH (1-0) kinematics in the massive G351.77 protocluster
N. A. Sandoval-Garrido, A. M. Stutz, R. H. Álvarez-Gutiérrez +20
ALMA-IMF observed 15 massive protoclusters capturing multiple spectral lines and the continuum emission. We focus on the G351.77 protocluster ( 2500 M, estimated fr…
Fractional Einstein-Gauss-Bonnet scalar field cosmology
Bayron Micolta-Riascos, Alfredo D. Millano, Genly Leon +3
Our paper introduces a new theoretical framework called the Fractional Einstein--Gauss--Bonnet scalar field cosmology, which has important physical implications. Using fractional c…
WIMP dark matter in bulk viscous non-standard cosmologies
Esteban González, Carlos Maldonado, N. Stefanía Mite +1
In this paper, we explored an extension of the classical non-standard cosmological scenario in which the new field, , which interacts with the radiation component in the early u…
Position displacement of diffuse interstellar bands
G. Galazutdinov, J. Krełowski, Y. Beletsky +1
We re-consider the already published phenomenon: the blue shift of diffuse interstellar bands, observed in spectra of HD34078 (AE Aur) and members of the Sco OB1 association, in pa…
