Active Brownian Rods
Fernando Peruani
Here, I review the large-scale properties of collections of active Brownian elongated objects, in particular rods, moving in a dissipative medium/substrate. I address the problem b…
Imitation Combined with a Characteristic Stimulus Duration Results in Robust Collective Decision-making in Sheep
Sylvain Toulet, Jacques Gautrais, Richard Bon +1
For group-living animals, reaching consensus to stay cohesive is crucial for their fitness, particularly when collective motion starts and stops. Understanding the decision-making…
Besicovitch Covering Property on graded groups and applications to measure differentiation
Enrico Le Donne, Severine Rigot
We give a complete answer to which homogeneous groups admit homogeneous distances for which the Besicovitch Covering Property (BCP) holds. In particular, we prove that a stratified…
The XXL Survey VII: A supercluster of galaxies at z=0.43
E. Pompei, C. Adami, D. Eckert +15
The XXL Survey is the largest homogeneous and contiguous survey carried out with XMM-Newton. Covering an area of 50 square degrees distributed over two fields, it primarily investi…
The XXL Survey: I. Scientific motivations - XMM-Newton observing plan - Follow-up observations and simulation programme
M. Pierre, F. Pacaud, C. Adami +89
We present the XXL Survey, the largest XMM programme totaling some 6.9 Ms to date and involving an international consortium of roughly 100 members. The XXL Survey covers two extrag…
The XXL Survey. II. The bright cluster sample: catalogue and luminosity function
F. Pacaud, N. Clerc, P. A. Giles +40
Context. The XXL Survey is the largest survey carried out by the XMM-Newton satellite and covers a total area of 50 square degrees distributed over two fields. It primarily aims at…
Structures and components in galaxy clusters: observations and models
A. M. Bykov, E. M. Churazov, C. Ferrari +5
Clusters of galaxies are the largest gravitationally bounded structures in the Universe dominated by dark matter. We review the observational appearance and physical models of plas…
Efimov physics with spin-isospin fermions
A. Kievsky, M. Gattobigio
The structure of few-fermion systems having spin-isospin symmetry is studied using potential models. The strength and range of the two-body potentials are fixed to describe l…
New constraints on Saturn's interior from Cassini astrometric data
Valéry Lainey, Robert A. Jacobson, Radwan Tajeddine +15
Using astrometric observations spanning more than a century and including a large set of Cassini data, we determine Saturn's tidal parameters through their current effects on the o…
A new approach to analytic, non-perturbative, gauge-invariant QCD renormalization is described, with applications to high energy elastic pp-scattering
H. M. Fried, P. H. Tsang, Y. Gabellini +2
A new non-perturbative, gauge-invariant model QCD renormalization is applied to high energy elastic pp-scattering. The differential cross-section deduced from this model displays a…
On the multi-symplectic structure of the Serre-Green-Naghdi equations
Marx Chhay, Denys Dutykh, Didier Clamond
In this short note, we present a multi-symplectic structure of the Serre-Green-Naghdi (SGN) equations modelling nonlinear long surface waves in shallow water. This multi-symplectic…
The dust disk and companion of the nearby AGB star L2 Puppis - SPHERE/ZIMPOL polarimetric imaging at visible wavelengths
P. Kervella, M. Montargès, E. Lagadec +6
The bright southern star L2 Pup is a particularly prominent asymptotic giant branch (AGB) star, as its distance of 64 pc makes it the nearest of its type. We report new adaptive op…
First light of the VLT planet finder SPHERE. II. The physical properties and the architecture of the young systems PZ Tel and HD 1160 revisited
A. -L. Maire, M. Bonnefoy, C. Ginski +68
[Abridged] Context. The young systems PZ Tel and HD 1160, hosting known low-mass companions, were observed during the commissioning of the new planet finder SPHERE with several ima…
First light of the VLT planet finder SPHERE. I. Detection and characterization of the sub-stellar companion GJ 758 B
A. Vigan, M. Bonnefoy, C. Ginski +72
GJ758 B is a brown dwarf companion to a nearby (15.76 pc) solar-type, metal-rich (M/H = +0.2 dex) main-sequence star (G9V) that was discovered with Subaru/HiCIAO in 2009. From prev…
The Araucaria Project: A study of the classical Cepheid in the eclipsing binary system OGLE LMC562.05.9009 in the Large Magellanic Cloud
Wolfgang Gieren, Bogumil Pilecki, Grzegorz Pietrzynski +26
We present a detailed study of the classical Cepheid in the double-lined, highly eccentric eclipsing binary system OGLE-LMC562.05.9009. The Cepheid is a fundamental mode pulsator w…
First combined search for neutrino point-sources in the Southern Hemisphere with the ANTARES and IceCube neutrino telescopes
ANTARES Collaboration, S. Adrián-Martínez, A. Albert +426
We present the results of searches for point-like sources of neutrinos based on the first combined analysis of data from both the ANTARES and IceCube neutrino telescopes. The combi…
A semi-analytical model for exploring Galilean satellites formation from a massive disk
Yamila Miguel, Shigeru Ida
A better knowledge of Jovian satellites' origins will bring light on the environment that surrounded Jupiter during its formation and can help us to understand the characteristics…
Approximate categorical structures
Abdelkrim Aliouche, Carlos Simpson
We consider notions of metrized categories, and then approximate categorical structures defined by a function of three variables generalizing the notion of -metric space. We pro…
