The VOICE Survey : VST Optical Imaging of the CDFS and ES1 Fields
(Proceedings of Science (PoS), 2016-01)
We present the VST Optical Imaging of the CDFS and ES1 Fields (VOICE) Survey, a VST INAF Guaranteed Time program designed to provide optical coverage of two 4 deg2 cosmic windows in the Southern hemisphere. VOICE provides ...
4D higher spin black holes with nonlinear scalar fluctuations
(Springer Verlag, 2017-10)
We construct an infinite-dimensional space of solutions to Vasiliev’s equations in four dimensions that are asymptotic to AdS spacetime and superpose massless scalar particle modes over static higher spin black holes. Each ...
VVV Survey Microlensing Events in the Galactic Center Region
(Institute of Physics Publishing, 2017)
We search for microlensing events in the highly reddened areas surrounding the Galactic center using the near-IR observations with the VISTA Variables in the Vía Láctea Survey (VVV). We report the discovery of 182 new ...
Blue horizontal branch stars using the VVV survey
(Universidad Andrés Bello, 2018)
The VISTA Variables in the V a L actea (VVV) is an ESO Public Survey, part of the Paranal Observatory. The VVV Survey is targeting the central parts of our galaxy, covering an area of 540 square degrees. Its main goal is ...
Ti film deposition process of a plasma focus: Study by an experimental design
(American Institute of Physics Inc., 2017-10)
The plasma generated by plasma focus (PF) devices have substantially different physical characteristics from another plasma, energetic ions and electrons, compared with conventional plasma devices used for plasma ...
Synthesis and morphological characterization of nanocomposite based on anodic TiO2 nanotubes and poly(N-maleoyl Glycine-CO-Acrylic acid)
(Sociedad Chilena de Quimica, 2017)
In this study, we examined the synthesis, and characterization of TiO2/poly(N-maleoylglycine-co-acrylic acid) (TiO2/poly(MG-co-AA)) nanocomposite. The nanocomposite was prepared by the dispersion of TiO2 nanotubes in a ...
Observations of field and cluster RR Lyræ with Spitzer. Towards high precision distances with Population II stellar tracers
(EDP Sciences, 2017-09)
We present our project to calibrate the RR Lyræ period-luminosity-metallicity relation using a sample of Galactic calibrators in the halo and globular clusters.
The Gaia -ESO Survey: Double-, triple-, and quadruple-line spectroscopic binary candidates
(EDP Sciences, 2017)
Context. The Gaia-ESO Survey (GES) is a large spectroscopic survey that provides a unique opportunity to study the distribution of spectroscopic multiple systems among different populations of the Galaxy. Aims. Our aim is ...
What is the Milky Way outer halo made of?: High resolution spectroscopy of distant red giants
(EDP Sciences, 2017)
In a framework where galaxies form hierarchically, extended stellar haloes are predicted to be an ubiquitous feature around Milky Way-like galaxies and to consist mainly of the shredded stellar component of smaller galactic ...
Vacuum degeneracy and Conformal Mass in Lovelock AdS gravity
(Springer Verlag, 2017-11)
It is shown that the notion of Conformal Mass can be defined within a given anti-de Sitter (AdS) branch of a Lovelock gravity theory as long as the corresponding vacuum is not degenerate. Indeed, conserved charges obtained ...
