Recovering isolated galaxies from large scale surveys: problems and strategies

The large survey programs being performed nowadays, being the SDSS their flagship, provide us with morphological parameters which allow for extraction of large galaxy samples. We will analyze the methodology for obtaining an AMIGA-like catalogue of isolated galaxies from the SDSS DR5 photometric catalogue of galaxy objects, together with the roadblocks found in the process, and suggested workarounds.Comment: 4 pages, 2 figures, to appear in the Proceedings of the International Conference CIG09: Galaxies in Isolation, held in May 19th in Granada, Spai

Gipsy 3D: Analysis, visualization and vo-tools

4 pages, 1 figure.-- Editors: Bohlender, David A.; Durand, Daniel; Dowler, Patrick.-- This volume contains papers that were presented to the 18th annual conference on Astronomical Data Analysis Software and Systems (ADASS XVIII), which was held on 2--5 November in Québec City, QC, Canada.The scientific goals of the AMIGA project are based on the analysis of a significant amount of spectroscopic 3D data. In order to perform this work we present an initiative to develop a new VO compliant package, including present core applications and tasks offered by the Groningen Image Processing System (GIPSY), and new ones based on use cases elaborated in collaboration with advanced users. One of the main goals is to provide local interoperability between GIPSY (visualization and data analysis) and other VO software. The connectivity with the Virtual Observatory environment will provide general access to 3D data VO archives and services, maximizing the potential for scientific discovery.This work will be partially supported by the Spanish Ministry of Science and Innovation thanks to DGI Grant AYA2008-06181-C02- 01.Peer reviewe

Virtual observatory activities in the AMIGA group

6 pages, 3 figures.-- En: Highlights of Spanish Astrophysics V, Proceedings of the eighth Scientific Meeting of the Spanish Astronomical Society (SEA)The AMIGA project (Analysis of the interstellar Medium of Isolated GAlaxies) is an international collaboration led from the Instituto de Astrof\'isica de Andaluc\'ia (CSIC). The group's experience in radio astronomy databases turned, as a natural evolution, into an active participation in the development of data archives and radio astronomy software. The contributions of the group to the VO have been mostly oriented towards the deployment of large VO compliant databases and the development of access interfaces (IRAM 30m Pico Veleta, DSS-63 70m in Robledo de Chavela). We also have been working in the development of an API for VO tools that will ease access to VO registries and communication between different VO software. A collaboration with the Kapteyn Astronomical Institute has started recently in order to perform a complete renovation of the only existing high-level software (GIPSY) for the analysis of datacubes, allowing its fully integration in the VO.Peer reviewe

AstroTaverna-building workflows with Virtual Observatory services

Special issue on The Virtual Observatory: I, edited by Robert HanischDespite the long tradition of publishing digital datasets in Astronomy, and the existence of a rich network of services providing astronomical datasets in standardized interoperable formats through the Virtual Observatory (VO), there has been little use of scientific workflow technologies in this field. In this paper we present AstroTaverna, a plugin that we have developed for the Taverna Workbench scientific workflow management system. It integrates existing VO web services as first-class building blocks in Taverna workflows, allowing the digital capture of otherwise lost procedural steps manually performed in e.g. GUI tools, providing reproducibility and re-use. It improves the readability of digital VO recipes with a comprehensive view of the entire automated execution process, complementing the scarce narratives produced in the classic documentation practices, transforming them into living tutorials for an efficient use of the VO infrastructure. The plugin also adds astronomical data manipulation and transformation tools based on the STIL Tool Set and the integration of Aladin VO software, as well as interactive connectivity with SAMP-compliant astronomy tools. © 2014 Elsevier B.V. All rights reserved.AstroTaverna has been developed in the framework of the Wf4Ever Project34 270129 funded under EU FP7 Digital Libraries and Digital Preservation (ICT-2009.4.1), which leverages workflow technology in order to preserve the scientific methodology, facilitating the reuse and exchange of digital knowledge, and to enable the inspection of the reproducibility of scientific investigation results. Part of the improvements is being undertaken in the framework of CANUBE Project35 CEI2013-P-14, an Open Science project granted by the Second Call for Proposals of the Bio-TIC Campus of International Excellence36 of the University of Granada, in Spain.
