A Theory of Partial Truth for Scientific Statements
Gustavo E. Romero
Scientific representations often combine accurate and inaccurate components, which a single bivalent classification does not distinguish. This paper develops a restricted formal fr…
Constraining the white-dwarf mass in the intermediate polar IGR J17014-4306 using X-ray and optical spectroscopy
D. C. Souza, M. P. Diaz, A. S. Oliveira +7
Intermediate polars (IPs), a subclass of magnetic cataclysmic variables, often show discrepancies between white-dwarf (WD) mass measurements from X-ray spectral modeling and optica…
Validating an X-ray-based method for identifying Fermi blazars
J. L. Weiss, E. J. Marchesini, I. Andruchow +1
Context. Blazars are the main population of active galactic nuclei (AGNs) detected in gamma rays by Fermi. However, around 34% of Fermi sources remain unidentified, partly due to t…
The PAU Survey: Active galactic nucleus galaxies in galaxy pairs
F. Duplancic, M. Siudek, D. Navarro-Gironés +21
Aims. Leveraging the high-precision photometric redshifts of the Physics of the Accelerating Universe Survey (PAUS), we aim to investigate the connection between active galactic nu…
Spherical thin shells with charge in unimodular gravity
Gabriel R. Bengochea, Ernesto F. Eiroa, Griselda Figueroa-Aguirre
We construct spherically symmetric thin shells in unimodular gravity (UG) and analyze their dynamical stability under radial, symmetry-preserving perturbations. We use the UG junct…
On Asynchrony and Reversibility in CCS
Hernán Melgratti, Claudio Antares Mezzina, G. Michele Pinna
Asynchronous communication is a fundamental feature of modern distributed systems, where messages are emitted without requiring immediate synchronization with receivers. In process…
Infrared-excess sources in VVV: candidate debris discs, SED characterization, and variability analysis
P. Esteves, R. K. Saito, C. Chavero +9
Debris disks around main-sequence stars provide important insights into planetary formation and evolution; however, identifying these systems in the Galactic plane, where high inte…
New constraints on the binary system HD 327083 and its gaseous and dusty environments
L. Cidale, P. Marchiano, M. Kraus +11
Binary systems with circumbinary molecular and dust rings are of great interest because they provide insights into the dynamics and evolution of stellar systems and the chemistry o…
Pre-main Sequence B Stars Surrounding the Orion Nebula
P. H. F. B. Braz, A. Roman-Lopes, W. J. B. Corradi +6
Pre-main sequence (PMS) early-type stars are rare due to their rapid evolution. Confirming PMS B stars is accordingly valuable for constraining higher mass star formation scenarios…
PKS 2155-304: Long-Term Optical Photometric Monitoring and Variability Analysis
J. L. Weiss, I. Andruchow, E. J. Marchesini +6
Through the detailed study of the optical flux behaviour in blazars over time, it is possible to infer the conditions responsible for their observed emission. PKS 2155-304, a BL La…
Variables in S-PLUS: I. Multiband period-luminosity relations and reddening maps of the Magellanic Clouds using classical Cepheids
Debasish Hazarika, Carlos E. Ferreira Lopes, Márcio Catelan +12
Aims. Classical Cepheids (CCs) are fundamental standard candles for the extragalactic distance scale through their period-luminosity (P-L) relations. Although well calibrated in br…
Tuning ergodicity breaking: Anomalous diffusion under asymptotic power-law forcing
Raul V. B. Morás, M. Florencia Carusela, Luciano C. Lapas
In non-Markovian systems, distinct dynamical phases arise from the competition between internal memory and external forcing, encompassing thermalization, persistent ergodicity brea…
A micronova burst in the intermediate polar IGR J17014-4306
Alexandre S. Oliveira, D. C. Souza, G. J. M. Luna +1
We report the detection of a short optical burst in TESS data of IGR J17014-4306, the eclipsing intermediate polar with the longest known orbital period. The burst lasts 1.56 d and…
Adaptive arrival cost update for improving Moving Horizon Estimation performance
Guido Sanchez, Marina Murillo, Leonardo Giovanini
Moving horizon estimation is an efficient technique to estimate states and parameters of constrained dynamical systems. It relies on the solution of a finite horizon optimization p…
Finite-Size Effects on the Critical End Point of Magnetized Quark Matter in the Nonlocal PNJL Model
G. Lugones, S. A. Ferraris, A. G. Grunfeld
We investigate finite-size effects in the - phase diagram of magnetized quark matter within the framework of a nonlocal extension of the Polyakov--Nambu--Jona-Lasinio (PNJL)…
Quantum collapse, local conservation of charge, and possible experimental consequences
F. Minotti, G. Modanese
We investigate the possibility that idealized quantum state-reduction processes may produce a local violation of charge conservation. If this occurs, the corresponding electromagne…
Measurements of the Higgs boson production, fiducial and differential cross-sections in the four lepton decay channel using 164 fb of data collected at = 13.6 TeV with the ATLAS detector
ATLAS Collaboration
Inclusive, differential and production-mode cross-section measurements of the Higgs boson are performed in the decay channel. The analysis uses proton-prot…
Expected redshift drift for tilted observers
Franco R. de Pedro, Gabriel R. Bengochea
Redshift drift is usually discussed for observers comoving with the cosmological background, but realistic observations are made by observers with nonzero peculiar motion. In this…
Data-Driven Modelling to predict forest fire spread in the Patagonian region in Argentina
Lucas Becerra, Monica Malen Denham, Alejandro B. Kolton +1
Wildfires are among the most severe disturbances affecting forest ecosystems, with over 50,000 hectares burned in Patagonia, Argentina, during 2025 alone. This study implements a R…
