On the GeV emission of the type I BdHN GRB 130427A
R. Ruffini, R. Moradi, J. A. Rueda +9
We propose that the "inner engine" of a type I binary-driven hypernova (BdHN) is composed of a Kerr black hole (BH) in a non-stationary state, embedded in a uniform magnetic field…
Imaging binary stars by the cross-correlation technique
Eric Aristidi, Marcel Carbillet, Jean-Félix Lyon +1
We present in this paper a technique for imaging binary stars from speckle data. This technique is based upon the computation of the cross-correlation between the speckle frames an…

Eric Aristidi, Yan Fantei-Caujolle, Aziz Ziad +3
We present first results of a new instrument, the Generalized Differential Image Motion Monitor (GDIMM), aiming at monitoring parameters of the optical turbulence (seeing, isoplana…
Turbulence monitoring at the Plateau de Calern with the GDIMM instrument
Eric Aristidi, Yan Fantei-Caujolle, Julien Chabé +3
We present some statistics of turbulence monitoring at the Plateau de Calern (France), with the Generalised Differential Image Motion Monitor (GDIMM). This instrument allows to mea…
On a new method to estimate distance, reddening and metallicity of RR Lyrae stars using optical/near-infrared (,,,,,) mean magnitudes: Centauri as a first test case
G. Bono, G. Iannicola, V. F. Braga +26
We developed a new approach to provide accurate estimates of metal content, reddening and true distance modulus of RR Lyrae stars (RRLs). The method is based on homogeneous optical…
Multi-epoch Direct Imaging and Time-Variable Scattered Light Morphology of the HD 163296 Protoplanetary Disk
Evan A. Rich, John P. Wisniewski, Thayne Currie +58
We present H-band polarized scattered light imagery and JHK high-contrast spectroscopy of the protoplanetary disk around HD 163296 observed with the HiCIAO and SCExAO/CHARIS instru…
Two Predictions of supernova: GRB 130427A / SN 2013cq and GRB 180728A / SN 2018fip
Yu Wang, Jorge A. Rueda, Remo Ruffini +4
On 2018 July 28, GRB 180728A triggered \textit{Swift} satellites and, soon after the determination of the redshift, we identified this source as a type II binary-driven hypernova (…
New constraints on sterile neutrino dark matter from the Galactic Center
R. Yunis, C. R. Argüelles, N. E. Mavromatos +4
We calculate the most stringent constraints up to date on the parameter space for sterile neutrino warm dark matter models possessing a radiative decay channel into X-rays. These c…
Chiral Symmetry Breaking out of QCD Effective Locality
Thierry Grandou, Ralf Hofmann, Peter H. Tsang
The QCD non-perturbative property of Effective Locality whose essential meaning has been disclosed recently, is here questioned about the chiral symmetry breaking phenomenon, one o…
Galaxies flowing in the oriented saddle frame of the cosmic web
K. Kraljic, C. Pichon, Y. Dubois +12
The strikingly anisotropic large-scale distribution of matter made of an extended network of voids delimited by sheets, themselves segmented by filaments, within which matter flows…
The XXL Survey: XXVII. The 3XLSS point source catalogue
L. Chiappetti, S. Fotopoulou, C. Lidman +35
We present the version of the point source catalogue of the XXL Survey that was used, in part, in the first series of XXL papers. In this paper we release, in our database in Milan…
The XXL Survey XX: The 365 cluster catalogue
C. Adami, P. Giles, E. Koulouridis +54
In the currently debated context of using clusters of galaxies as cosmological probes, the need for well-defined cluster samples is critical. The XXL Survey has been specifically d…
The XXL Survey XXV. Cosmological analysis of the C1 cluster number counts
F. Pacaud, M. Pierre, J. -B. Melin +25
Context. We present an estimation of cosmological parameters with clusters of galaxies. Aims. We constrain the , , and parameters from a stand-alone sample of X-ray c…
A rare event algorithm links transitions in turbulent flows with activated nucleations
Freddy Bouchet, Joran Rolland, Eric Simonnet
Many turbulent flows undergo drastic and abrupt configuration changes with huge impacts. As a paradigmatic example we study the multistability of jet dynamics in a barotropic beta…
The VIMOS Public Extragalactic Redshift Survey (VIPERS): Unbiased clustering estimate with VIPERS slit assignment
F. G. Mohammad, D. Bianchi, W. J. Percival +34
The VIPERS galaxy survey has measured the clustering of galaxies, enabling a number of measurements of galaxy properties and cosmological redshift-space distortions (RS…
Constraining the gap size in the disk around HD 100546 in the mid-infrared
Narges Jamialahmadi, Thorsten Ratzka, Olja Panic +6
We refine the gap size measurements of the disk surrounding the Herbig Ae star HD 100546 in the N band. Our new mid-infrared interferometric (MIDI) data have been taken with the UT…
SPHERE / ZIMPOL high resolution polarimetric imager. I. System overview, PSF parameters, coronagraphy, and polarimetry
H. M. Schmid, A. Bazzon, R. Roelfsema +59
We describe the Zurich Imaging Polarimeter (ZIMPOL), the visual focal plane subsystem of the SPHERE "VLT planet finder", which pushes the limits of current AO systems to shorter wa…
Orbital characterization of GJ1108A system, and comparison of dynamical mass with model-derived mass for resolved binaries
T. Mizuki, M. Kuzuhara, K. Mede +55
We report an orbital characterization of GJ1108Aab that is a low-mass binary system in pre-main-sequence phase. Via the combination of astrometry using adaptive optics and radial v…
