Matter Creation in Unimodular Gravity Cosmology
Víctor H. Cárdenas, Miguel Cruz, Samuel Lepe
We investigate matter creation in the cosmological framework of unimodular gravity. We keep the energy density , pressure , particle number density , and particle number $…
Soft charges and zero modes at null boundaries
Dušan Đorđević, Olivera Miskovic, Antonia Montecinos +1
Asymptotic symmetries at null boundaries provide a powerful window into the soft sector of field theories, revealing conserved charges and infinite-dimensional symmetry algebras be…
Direct detections of white dwarfs in four WD+dM post-common envelope binaries within 20 pc
Mairi W. O'Brien, David J. Wilson, Pier-Emmanuel Tremblay +5
Characterising post-common envelope binaries (PCEBs) containing a white dwarf and a main-sequence companion is essential for improving theories of binary evolution. This paper pres…
Multiplicity distributions in DIS for heavy nucleus
Carlos Contreras, José Garrido
We found solutions to the linear but with complicated kernel and non-homogeneous evolution equations for the cross sections of productions of -cut Balitsky-Fadin-Kuraev-Lipatov…
Thermodynamic behavior of cosmological models with fractional entropy
Miguel Cruz, Diego da Silva, Simón González +3
We investigate the thermodynamic and phenomenological implications of a cosmological model governed by fractional entropy applied to the apparent horizon of a flat Friedmann-Lemaît…
A modest change in magnetic braking at the fully convective boundary explains cataclysmic variable evolution
Joaquín A. Barraza-Jorquera, Matthias R. Schreiber, Stuart Littlefair +2
Context. For decades, reproducing the orbital period distribution of non-magnetic Cataclysmic Variables (CVs) seemed to require a drastic decrease, usually termed disruption, of an…
Holographic Weyl Anomaly and Kounterterms in AdS gravity
Giorgos Anastasiou, Jahaira Bonifacio-Chavez, Olivera Miskovic +1
The addition of Kounterterms to Einstein gravity leads to a finite action for asymptotically anti-de Sitter (AdS) spaces with a conformally flat boundary. In that sense, it provide…
Primordial non-Gaussianity -- Fast simulations and persistent summary statistics
Juan Calles, Gabriella Contardo, Jorge Noreña +2
We investigate the sensitivity of topological and traditional summary statistics to primordial non-Gaussianity (PNG) using two suites of simulations. First, we introduce a new simu…
The holographic origin of future singularities and the role of spatial curvature in cosmic expansion
Miguel Cruz, Samuel Lepe, Joel Saavedra
We investigate the fundamental cosmological implications of holographic dark energy using the Granda-Oliveros (GO) infrared cutoff, spatial curvature, and generalized entropies. We…
Cosmological implications of Bumblebee theory on an FLRW background
Manuel Gonzalez-Espinoza, Grigorios Panotopoulos, Francisco Tello-Ortiz
We investigate some cosmological implications at background level of the Bumblebee model. The phase-space, the critical points and their stability are analyzed in detail applying w…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
Slow-Fast Evolution of Scalar Fields in Higher-Order Cosmological Gravity: Dynamics Inspired by the Pais--Uhlenbeck Oscillator
Manuel Gonzalez-Espinoza, Genly Leon, Yoelsy Leyva +3
We investigate the cosmological dynamics of scalar fields governed by higher-order gravity, with particular emphasis on models inspired by the Pais-Uhlenbeck oscillator--a prototyp…
Localisation and host galaxy identification of new Fast Radio Bursts with MeerKAT
Inés Pastor-Marazuela, Alexa C. Gordon, Ben Stappers +18
Accurately localising fast radio bursts (FRBs) is essential for understanding their birth environments and for their use as cosmological probes. Recent advances in radio interferom…
Predicting potentially abusive clauses in Chilean terms of services with natural language processing
Christoffer Loeffler, Andrea Martínez Freile, Tomás Rey Pizarro
This study addresses the growing concern of information asymmetry in consumer contracts, exacerbated by the proliferation of online services with complex Terms of Service that are…
Quasi-fluxon bubble dynamics in a rapid oscillatory microwave field
Alicia G. Castro-Montes, Elram S. Figueroa, Juan F. Marín +1
In this article, we numerically study the dynamics of a two-dimensional quasi-fluxon bubble in an oscillatory regime stabilized by a localized annular force under a rapidly oscilla…
Galaxy Spectra Networks (GaSNet). III. Generative pre-trained network for spectrum reconstruction, redshift estimate and anomaly detection
Fucheng Zhong, Nicola R. Napolitano, Caroline Heneka +11
Classification of spectra (1) and anomaly detection (2) are fundamental steps to guarantee the highest accuracy in redshift measurements (3) in modern all-sky spectroscopic surveys…
An effective framework for strange metallic transport
Benoit Doucot, Ayan Mukhopadhyay, Giuseppe Policastro +2
Semi-holography, originally proposed as a model for conducting lattice electrons coupled to a holographic critical sector, leads to an effective theory of non-Fermi liquids with on…
Exceptional magic angles in non-Hermitian twisted bilayer graphene
Juan Pablo Esparza, Vladimir Juricic
Twisted bilayer graphene (TBG) features strongly correlated and topological phases due to its flat bands emerging near the magic angle. However, the effects of the non-Hermiticity,…
Galactic transient sources with the Cherenkov Telescope Array Observatory
Cherenkov Telescope Array Observatory Consortium
A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…

Supersymmetric smooth distributions of M2-branes as AdS solitons
A. Anabalón, D. Astefanesei, A. Gallerati +1
We show that the singularities of certain distributions of M2-branes can be removed by adding a Wilson loop around a compact direction along the brane. The holographic coordinate n…
