The VIMOS Public Extragalactic Redshift Survey (VIPERS). AGN feedback in [NeV] emitters
D. Vergani, B. Garilli, M. Polletta +36
Using an unconventional single line diagnostic that unambiguously identifies AGNs in composite galaxies we report statistical differences in the properties (stellar age, [OII] lumi…
On the ultra-relativistic Prompt Emission (UPE), the Hard and Soft X-ray Flares, and the extended thermal emission (ETE) in GRB 151027A
R. Ruffini, L. Becerra, C. L. Bianco +12
We analyze GRB 151027A within the binary-driven hypernova (BdHN) approach, with progenitor a carbon-oxygen core on the verge of a supernova (SN) explosion and a binary companion ne…
On a GRB afterglow model consistent with hypernovae observations
R. Ruffini, M. Karlica, N. Sahakyan +5
We describe the afterglows of the long gamma-ray-burst (GRB) 130427A within the context of a binary-driven hypernova (BdHN). The afterglows originate from the interaction between a…
Tech Report: A Fast Multiscale Spatial Regularization for Sparse Hyperspectral Unmixing
Ricardo Augusto Borsoi, Tales Imbiriba, José Carlos Moreira Bermudez +1
Sparse hyperspectral unmixing from large spectral libraries has been considered to circumvent limitations of endmember extraction algorithms in many applications. This strategy oft…
The XXL Survey: XXIII. The Mass Scale of XXL Clusters from Ensemble Spectroscopy
A. Farahi, V. Guglielmo, A. E. Evrard +34
An X-ray survey with the XMM-Newton telescope, XMM-XXL, has identified hundreds of galaxy groups and clusters in two 25 deg fields. Combining spectroscopic and X-ray observatio…
On the 4D Nonlinear Schrödinger equation with combined terms under the energy threshold
Changxing Miao, Tengfei Zhang, Jiqiang Zheng
In this paper, we consider the longtime dynamics of the solutions to focusing energy-critical Schrödinger equation with a defocusing energy-subcritical perturbation term under a gr…
A better characterization of the chemical composition of exoplanets atmospheres with ARIEL
Olivia Venot, Benjamin Drummond, Yamila Miguel +3
Since the discovery of the first extrasolar planet more than twenty years ago, we have discovered nearly four thousand planets orbiting stars other than the Sun. Current observatio…
On distribution formulas for complex and -adic polylogarithms
Hiroaki Nakamura, Zdzislaw Wojtkowiak
We study an -adic Galois analogue of the distribution formulas for polylogarithms with special emphasis on path dependency and arithmetic behaviors. As a goal, we obtain a no…
The XXL Survey: XXII. The XXL-North spectrophotometric sample and galaxy stellar mass function in X-ray detected groups and clusters
V. Guglielmo, B. M. Poggianti, B. Vulcani +42
The fraction of galaxies bound in groups in the nearby Universe is high (50% at z~0). Systematic studies of galaxy properties in groups are important in order to improve our unders…
Decentralized Online Learning with Kernels
Alec Koppel, Santiago Paternain, Cedric Richard +1
We consider multi-agent stochastic optimization problems over reproducing kernel Hilbert spaces (RKHS). In this setting, a network of interconnected agents aims to learn decision f…
An open mapping theorem for finitely copresented Esakia spaces
Samuel J. van Gool, Luca Reggio
We prove an open mapping theorem for the topological spaces dual to finitely presented Heyting algebras. This yields in particular a short, self-contained semantic proof of the uni…
Dynamics of elastically strained islands in presence of an anisotropic surface energy
Guido Schifani, Médéric Argentina, Thomas Frisch
The equilibrium solutions and coarsening dynamics of strained semi-conductor islands are investigated analytically and numerically. We develop an analytical model to study the effe…
Emergence of a single cluster in Vicsek's model at very low noise
Lucas Barberis
The classic Vicsek model [Phys.Rev.Lett. {\bf75},1226(1995)] is studied in the regime of very low noise intensities, which is shown to be characterized by a cluster (MC) that conta…
The VIMOS Public Extragalactic Redshift Survey (VIPERS): An unbiased estimate of the growth rate of structure at using the clustering of luminous blue galaxies
F. G. Mohammad, B. R. Granett, L. Guzzo +34
We use the VIPERS final data release to investigate the performance of colour-selected populations of galaxies as tracers of linear large-scale motions. We empirically select volum…
Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
Mass and p-factor of the type II Cepheid OGLE-LMC-T2CEP-098 in a binary system
Bogumił Pilecki, Wolfgang Gieren, Radosław Smolec +10
We present the results of a study of the type II Cepheid () in the eclipsing binary system OGLE-LMC-T2CEP-098 (). The Cepheid belongs to the…
GRB 081024B and GRB 140402A: two additional short GRBs from binary neutron star mergers
Y. Aimuratov, R. Ruffini, M. Muccino +6
Theoretical and observational evidences have been recently gained for a two-fold classification of short bursts: 1) short gamma-ray flashes (S-GRFs), with isotropic energy $E_{iso}…
Early X-ray Flares in GRBs
R. Ruffini, Y. Wang, Y. Aimuratov +17
We analyze the early X-ray flares in the GRB "flare-plateau-afterglow" (FPA) phase observed by Swift-XRT. The FPA occurs only in one of the seven GRB subclasses: the binary-driven…
Interferometric confirmation of "water fountain" candidates
Jose F. Gomez, Olga Suarez, J. Ricardo Rizzo +4
Water fountain stars (WFs) are evolved objects with water masers tracing high-velocity jets (up to several hundreds of km s). They could represent one of the first manifesta…
