R. J. Hanisch, C. Arviset, F. Genova +1
This document describes the types of official IVOA documents and the process by which documents are advanced from Working Drafts to formal Recommendations.
A method for determining radio continuum spectra, and its application to large surveys
B. Vollmer, E. Davoust, P. Dubois +3
A new tool to extract cross-identifications and radio continuum spectra from radio catalogues contained in the VIZIER database of the CDS is presented. The code can handle radio su…
Probabilistic multi-catalogue positional cross-match
F. -X. Pineau, S. Derriere, C. Motch +8
We lay the foundations of a statistical framework for multi-catalogue cross-correlation and cross-identification based on explicit simplified catalogue models. A proper identificat…
Luminous AGB stars in nearby galaxies. A study using Virtual Observatory tools
P. Tsalmantza, E. Kontizas, L. Cambresy +3
Aims. This study focuses on very luminous Mbol<-6.0 mag AGB stars with J-Ks>1.5 mag and H-Ks>0.4 mag in the LMC, SMC, M31, and M33 from 2MASS data. Methods.The data were taken from…
The ARCHES project
C. Motch, F. Carrera, F. Genova +12
ARCHES (Astronomical Resource Cross-matching for High Energy Studies) is a FP7-Space funded project whose aim is to provide the international astronomical community with well-chara…
The SPECFIND V2.0 catalogue of radio cross-identifications and spectra. SPECFIND meets the Virtual Observatory
B. Vollmer, B. Gassmann, S. Derriere +6
The new release of the SPECFIND radio cross-identification catalogue, SPECFIND V2.0, is presented. It contains 107488 cross-identified objects with at least three radio sources obs…
Hierarchical progressive surveys. Multi-resolution HEALPix data structures for astronomical images, catalogues, and 3-dimensional data cubes
P. Fernique, M. G. Allen, T. Boch +8
Scientific exploitation of the ever increasing volumes of astronomical data requires efficient and practical methods for data access, visualisation, and analysis. Hierarchical sky…
The precision of large radio continuum source catalogues- An application of the SPECFIND tool
B. Vollmer, E. Davoust, P. Dubois +3
The accuracy in position and flux density of 19 large radio continuum source catalogues has been determined using SPECFIND, a new tool recently made available through the CDS. The…
An Hierarchical Approach to Big Data
M. G. Allen, P. Fernique, T. Boch +7
The increasing volumes of astronomical data require practical methods for data exploration, access and visualisation. The Hierarchical Progressive Survey (HiPS) is a HEALPix based…
French SKA White Book - The French Community towards the Square Kilometre Array
F. Acero, J. -T. Acquaviva, R. Adam +175
The "Square Kilometre Array" (SKA) is a large international radio telescope project characterised, as suggested by its name, by a total collecting area of approximately one square…
Automated object classification with ClassX
A. A. Suchkov, T. A. McGlynn, L. Angelini +13
ClassX is a project aimed at creating an automated system to classify X-ray sources and is envisaged as a prototype of the Virtual Observatory. As a system, ClassX integrates into…
On the usefulness of finding charts Or the runaway carbon stars of the Blanco & McCarthy field 37
C. Loup, N. Delmotte, D. Egret +2
We have been recently faced with the problem of cross--identifying stars recorded in historical catalogues with those extracted from recent fully digitized surveys (such as DENIS a…
