Optimization of adaptive optics correction during observations: Algorithms and system parameters identification in closed-loop
Clémentine Béchet, Michel Tallon, Éric Thiébaut
The adaptive optics (AO) on the European Extremely Large Telescope, as well as earlier pathfinders like the Adaptive Optics Facility, at the Very Large Telescope in 2014, will no l…
The GECKOS survey: Assembly history of the lenticular galaxy NGC 3957
Yuchen Ding, Marie Martig, Ling Zhu +24
We analyse the assembly history of the edge-on lenticular galaxy NGC 3957 using deep integral-field spectroscopic MUSE data from the GECKOS survey. By applying a dust-corrected Mul…
Virial-based extraction of structures in numerical simulations: The vibes tool
Simon Chevalier, Fabien Louvet, Yann Bernard +9
The processes that determine the stellar initial mass function (IMF) and its connection to the core mass function (CMF) are among the major open questions in star formation. The de…
Lithium-rich M-dwarfs at the ZAMS: Evidence for planetary engulfment?
R. D. Jeffries, R. J. Jackson, I. Baraffe
We identify 6 early M-dwarfs, in 3 open clusters (NGC 2451a, Blanco 1 and NGC 2516) at ages of 50-200 Myr, that are anomalously enriched in lithium compared with Li-depleted siblin…
Coherent modeling of double-folded ring polymers and their underlying random tree structure
Pieter H. W. van der Hoek, Angelo Rosa, Elham Ghobadpour +1
Topologically constrained genome-like polymers often double-fold into tree-like configurations, which can be modelled on the level of folded (ring) polymers or on the level of the…
The slope of the power spectrum of the density field in isothermal supersonic compressible turbulence
Pierre Dumond, Jérémy Fensch, Gilles Chabrier +1
The power spectrum (PS) of the density field in supersonic turbulence is a fundamental quantity that characterizes the statistical properties of the structures formed in compressib…
Backreaction and the Role of Spatial Curvature in the Cosmic Neighborhood
Marco Galoppo, Thomas Buchert, Pierre Mourier
We present the first direct computation of spatially averaged dynamical quantities in the local Universe, employing the Cosmicflows-4++ reconstruction and a covariant scalar averag…
Novel Realizations of Warp Drive Spacetimes as Solutions of General Relativity
Thomas Buchert, Antony Frackowiak
We first take a closer look at the original warp drive proposal by Alcubierre, examine its kinematics in the context of a covariant 3+1 setting, and explain some drawbacks of this…
Accelerating charging dynamics of electric double-layer capacitors
Megh Dutta, Ivan Palaia, Emmanuel Trizac +1
Electric double-layer capacitors (EDLCs), consisting of an ionic fluid between two metallic electrodes, are electrochemical energy storage devices complementary to batteries, allow…
Exploration of the inner region of the system HD 142527
T. M. H. Tran, M. Langlois, O. Flasseur +6
HD 142527 is a well-studied intermediate-mass T Tauri star surrounded by a transitional disk with a large dust cavity, spiral structures, and an accreting low-mass companion. Despi…
MUSE-DARK III: The evolution of the radial acceleration relation at intermediate redshifts
B. I. Ciocan, N. F. Bouché, J. Fensch +5
The radial acceleration relation (RAR) is a tight empirical correlation between the observed radial acceleration (a_tot) and the baryonic radial acceleration (a_bar) measured acros…
THIVLVC: Retrieval Augmented Dependency Parsing for Latin
Luc Pommeret, Thibault Wagret, Jules Deret
We describe THIVLVC, a two-stage system for the EvaLatin 2026 Dependency Parsing task. Given a Latin sentence, we retrieve structurally similar entries from the CIRCSE treebank usi…
Entropic crystallization of geometrically frustrated magnets on 1/1 approximant Tsai-type quasicrystal
Oscar Novat, Ludovic D. C. Jaubert, Masafumi Udagawa
We have studied the antiferromagnetic Ising model on the icosahedral bcc lattice, as a model system of 1/1 approximant Tsai-type quasicrystals. We addressed thermal equilibrium pro…
Qiana: A First-Order Formalism to Quantify over Contexts and Formulas with Temporality
Simon Coumes, Pierre-Henri Paris, François Schwarzentruber +1
We introduce Qiana, a logic framework for reasoning on formulas that are true only in specific contexts. In Qiana, it is possible to quantify over both formulas and contexts to exp…
The spatio-temporal statistical structure of the turbulent dissipation field and its stochastic representation as a Gaussian Multiplicative Chaos
Wandrille Ruffenach, Laurent Chevillard
The present article concerns the stochastic modeling of the turbulent dissipation field and in particular its temporal evolution. To do so, we will be calling for a random distribu…
Cyclic reformation of subcritical perpendicular fast magnetosonic shocks due to oblique Whistler waves
ME Dieckmann, L Palodhi, M Francois +2
The stability of subcritical perpendicular fast magnetosonic shocks, which are propagating at 1.7 times the fast magnetosonic speed, is investigated using two-dimensional PIC simul…
Are supernovae driving turbulence in the solar neighborhood?
Georges Abboudeh, Patrick Hennebelle, Juan D. Soler +9
Turbulence plays an important role in shaping the interstellar medium, and strongly influences star formation. We aim to identify the physical processes capable of sustaining HI tu…
MUSE-DARK-II: 3D morpho-kinematic modelling of lensed galaxies. Tully-Fisher relation of star-forming galaxies
Alexandre Jeanneau, Johan Richard, Nicolas F. Bouché +5
In a series of papers on lensed kinematics, we seek to combine the sensitivity of 3D forward modelling to low signal-to-noise ratio outskirts with the enhanced spatial resolution o…
The SPHINX public data release. II. Using low-ionisation absorption lines and dust attenuation to predict Lyman continuum escape
Valentin Mauerhofer, Jérémy Blaizot, Thibault Garel +11
Low-ionisation state (LIS) absorption lines, such as SiII 1526, are widely used to trace the properties of the interstellar medium (ISM) in galaxies. These lines provide crucial in…
