TL;DR
The Taiwan Extragalactic Astronomical Data Center (TWEA-DC) aims to provide access to large extragalactic datasets, develop fast data indexing and matching tools, and offer advanced online analysis services for the Taiwanese and international astronomical community.
Contribution
This paper introduces TWEA-DC, the first comprehensive platform in Taiwan for extragalactic data access, fast indexing, and online analysis tools, advancing the country's astronomical data infrastructure.
Findings
Implementation of a fast indexing algorithm (BLINK) for sky data
Development of on-the-fly catalog matching service
Provision of automated analysis tools like photometric redshifts and cluster finders
Abstract
Founded in 2010, the Taiwan Extragalactic Astronomical Data Center (TWEA-DC) has for goal to propose access to large amount of data for the Taiwanese and International community, focusing its efforts on Extragalactic science. In continuation with individual efforts in Taiwan over the past few years, this is the first steppingstone towards the building of a National Virtual Observatory. Taking advantage of our own fast indexing algorithm (BLINK), based on a octahedral meshing of the sky coupled with a very fast kd-tree and a clever parallelization amongst available resources, TWEA-DC will propose from spring 2013 a service of "on-the-fly" matching facility, between on-site and user-based catalogs. We will also offer access to public and private raw and reducible data available to the Taiwanese community. Finally, we are developing high-end on-line analysis tools, such as an automated…
