Multiband Study of Radio Sources of the RCR Catalogue with Virtual Observatory Tools
We present early results of our multiband study of the RATAN Cold Revised (RCR) catalogue obtained from seven cycles of the “Cold” survey carried with the RATAN-600 radio telescope at 7.6 cm in 1980-1999, at the declination of the SS 433 source.

Topic Maps as a Virtual Observatory tool [PDF]
One major component of the VO will be catalogs measuring gigabytes and terrabytes if not more. Some mechanism like XML will be used for structuring the information. However, such mechanisms are not good for information retrieval on their own. For retrieval we use queries.

Capacity building in medicines development and regulation in Africa-Overview on recent progress. [PDF]
Aims Despite advances in health research and digital innovation, many African countries continue to face substantial resource constraints, fragmented capacity‐building efforts and a shortage of skilled professionals in medicines development and regulatory science.

SEARCH FOR BRIGHT NEARBY M DWARFS WITH VIRTUAL OBSERVATORY TOOLS [PDF]
Using Virtual Observatory tools, we cross-matched the Carlsberg Meridian 14 and the 2MASS Point Source catalogs to select candidate nearby bright M dwarfs distributed over ~ 25,000 deg^2. Here, we present reconnaissance low-resolution optical spectra for 27 candidates that were observed with the Intermediate Dispersion Spectrograph at the 2.5m Isaac ...

VisIVO: an interoperable visualisation tool for Virtual Observatory data [PDF]
We present VisIVO a software for the visualisation and analysis of astrophysical data which can be retrieved from the Virtual Observatory framework and for cosmological simulations. VisIVO is VO standards compliant and supports the most important astronomical data formats such as FITS, HDF5 and VOTables.

Virtual Observatory as a tool for stellar spectroscopy [PDF]
The Virtual Observatory (VO) is often presented as an all-purpose tool for the astronomer to do all his current work in a single web browser, from which he can control all data searches, reductions and mainly the full data analysis. This idea seems to be already fulfilling in certain fields of astronomy like is the search of unknown correlations ...

USING VIRTUAL OBSERVATORY TOOLS FOR ASTRONOMICAL RESEARCH
Construction of the Virtual Observatory (VO) is a great concern to the astronomical community in the 21st century. We present an outline of the concept and necessity of the va and the current status of various VO projects including the 15 national ones and the International Virtual Observatory Alliance (IVOA).

Identification of new hot subdwarf binary systems by means of Virtual Observatory tools
ABSTRACT The estimation of the binary fraction of hot subdwarfs is key to shed light on the different evolution scenarios proposed to explain the loss of the hydrogen envelope during the red giant branch phase. In this paper, we analyse the spectral energy distribution of the hot subdwarfs included in a recent and comprehensive catalogue
