Lagrangian theory of structure formation in relativistic cosmology. IV. Lagrangian approach to gravitational waves
Fosca Al Roumi, Thomas Buchert, Alexander Wiegand
The relativistic generalization of the Newtonian Lagrangian perturbation theory is investigated. In previous works, the perturbation and solution schemes that are generated by the…
Modular periodicity of the Euler numbers and a sequence by Arnold
Sanjay Ramassamy
For any positive integer , the sequence of the Euler up/down numbers reduced modulo was proved to be ultimately periodic by Knuth and Buckholtz. Based on computer simulation…
Fault orientation in damage failure under compression
Véronique Dansereau, Vincent Démery, Estelle Berthier +2
The Mohr-Coulomb criterion is widely used in geosciences to relate the state of stress at failure to the observed orientation of the resulting faults. This relation is based on the…
New spectro-photometric characterization of the substellar object HR 2562 B using SPHERE
D. Mesa, J. -L. Baudino, B. Charnay +32
HR2562 is an F5V star located at ~33 pc from the Sun hosting a substellar companion that was discovered using the GPI instrument. The main objective of the present paper is to prov…
Stresses in non-equilibrium fluids: Exact formulation and coarse grained theory
M. Krüger, A. Solon, V. Démery +2
Starting from the stochastic equation for the density operator, we formulate the exact (instantaneous) stress tensor for interacting Brownian particles, whose average value agrees…
On the Origin of Diffuse Ionized Gas in the Antennae Galaxy
Peter M. Weilbacher, Ana Monreal-Ibero, Anne Verhamme +14
The "Antennae Galaxy" (NGC 4038/39) is the closest major interacting galaxy system and therefore often taken as merger prototype. We present the first comprehensive integral field…
SPIRou Input Catalogue: Global properties of 440 M dwarfs observed with ESPaDOnS at CFHT
Pascal Fouqué, Claire Moutou, Lison Malo +13
Present and future high-precision radial-velocity spectrometers dedicated to the discovery of low-mass planets orbiting low-mass dwarfs need to focus on the best selected stars to…
Simultaneous, Multi-Wavelength Variability Characterization of the Free-Floating Planetary Mass Object PSO J318.5-22
Beth Biller, Johanna Vos, Esther Buenzli +15
We present simultaneous HST WFC3 + Spitzer IRAC variability monitoring for the highly-variable young (20 Myr) planetary-mass object PSO J318.5-22. Our simultaneous HST + Spit…
Diffusion-approximation for a kinetic equation with perturbed velocity redistribution process
Nils Caillerie, Julien Vovelle
We derive the hydrodynamic limit of a kinetic equation with a stochastic, short range perturbation of the velocity operator. Under some mixing hypotheses on the stochastic perturba…
Companions, Causality and Codensity
Damien Pous, Jurriaan Rot
In the context of abstract coinduction in complete lattices, the notion of compatible function makes it possible to introduce enhancements of the coinduction proof principle. The l…
Finite-time universality in nonequilibrium CFT
Krzysztof Gawedzki, Edwin Langmann, Per Moosavi
Recently, remarkably simple exact results were presented about the dynamics of heat transport in the local Luttinger model for nonequilibrium initial states defined by position-dep…
The Hilbert-Galton board
Arvind Ayyer, Sanjay Ramassamy
We introduce the Hilbert-Galton board as a variant of the classical Galton board. Balls fall into a row of bins at a rate depending on the bin, and at random times, each bin gets s…
Information Theory to probe Intrapartum Fetal Heart Rate Dynamics
Carlos Granero-Belinchon, Stéphane Roux, Patrice Abry +3
Intrapartum fetal heart rate (FHR) monitoring constitutes a reference tool in clinical practice to assess the baby health status and to detect fetal acidosis. It is usually analyze…
Ten-dimensional origin of Minkowski vacua in supergravity
Emanuel Malek, Henning Samtleben
Maximal supergravity in four dimensions admits two inequivalent dyonic gaugings of the group . Both admit a Minkowski vacuum…
Ionised gas structure of 100 kpc in an over-dense region of the galaxy group COSMOS-Gr30 at z ~ 0.7
Benoît Epinat, Thierry Contini, Hayley Finley +16
We report the discovery of a 10^4 kpc^2 gaseous structure detected in [OII] in an over-dense region of the COSMOS-Gr30 galaxy group at z~0.725 thanks to deep MUSE Guaranteed Time O…
Turbulence statistics in a 2D vortex condensate
Anna Frishman, Corentin Herbert
Disentangling the evolution of a coherent mean-flow and turbulent fluctuations, interacting through the non-linearity of the Navier-Stokes equations, is a central issue in fluid me…
Phoresis in turbulent flows
Vishwanath Shukla, Romain Volk, Mickaël Bourgoin +1
Phoresis, the drift of particles induced by scalar gradients in a flow, can result in an effective compressibility, bringing together or repelling particles from each other. Here,…
The nature of giant clumps in distant galaxies probed by the anatomy of the Cosmic Snake
Antonio Cava, Daniel Schaerer, Johan Richard +4
Giant stellar clumps are ubiquitous in high-redshift galaxies. They are thought to play an important role in the build-up of galactic bulges and as diagnostics of star formation fe…
Uniformity Transition for Ray Intensities in Random Media
Marc Pradas, Alain Pumir, Michael Wilkinson
This paper analyses a model for the intensity of distribution for rays propagating without absorption in a random medium. The random medium is modelled as a dynamical map. After $N…
The MUSE Hubble Ultra Deep Field Survey VI: The Faint-End of the Lya Luminosity Function at 2.91 < z < 6.64 and Implications for Reionisation
A. B. Drake, T. Garel, L. Wisotzki +19
We present the deepest study to date of the Lya luminosity function (LF) in a blank field using blind integral field spectroscopy from MUSE. We constructed a sample of 604 Lya emit…
The MUSE Hubble Ultra Deep Field Survey X. Ly Equivalent Widths at
Takuya Hashimoto, Thibault Garel, Bruno Guiderdoni +17
We present rest-frame Ly equivalent widths (EW) of 417 Ly emitters (LAEs) detected with Multi Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) at $2.9 < z…
Revealing the cluster of slow transients behind a large slow slip event
William B Frank, Baptiste Rousset, Cécile Lasserre +1
Capable of reaching similar magnitudes to large megathrust earthquakes (), slow slip events play a major role in accommodating tectonic motion on plate boundaries. These sli…
A characterization of Zoll Riemannian metrics on the 2-sphere
Marco Mazzucchelli, Stefan Suhr
The simple length spectrum of a Riemannian manifold is the set of lengths of its simple closed geodesics. We prove a theorem claimed by Lusternik: in any Riemannian 2-sphere whose…
On the Brownian separable permuton
Mickaël Maazoun
The Brownian separable permuton is a random probability measure on the unit square, which was introduced by Bassino, Bouvel, Féray, Gerin, Pierrot (2016) as the scaling limit of th…
