The advancement of astronomy requires integrating large volumes of data into a single environment for rapid exchange. The digital revolution, survey, ultra-large and space telescopes, data storage and processing systems, has led to an increase in the volume of data to petabyte and exabyte scales. How to effectively master this abundance of information is a pressing issue in astronomy. The answer is the Virtual Observatory (VO), which offers tools and technologies to navigate vast amounts of data and services, providing standardized protocols for publishing and accessing them, making the astronomical resources and services easily discoverable and accessible throughout the world. The system-forming nodes of the VO are its national divisions, exposing their data and services to the VO, taking them to a fundamentally new level of involvement in international astronomical research, increasing the efficiency of using their data, as well as enriching them with data from other observatories. Recently, Fesenkov Astrophysical Institute implemented the Kazakhstan National Virtual Observatory (KazVO), which is part of the International Alliance of Virtual Observatories, and made its digitized astroplates accessible in the VO. The active development of VO, the emergence of new initiatives and VO standards require continued work on the KazVO.
The goal of the Program:
Development of a digital virtual environment for astronomical research and provision of data analysis tools for the study of near and deep space objects.
The tasks of the Program:
1. Integration into a single digital ecosystem of the means of collecting, processing and analyzing data from ground-based astronomical complexes and the virtual observatory of Kazakhstan As part of this task, it is planned to significantly improve the existing KazVO Internet portal, in particular, bring it into compliance with VO standards, ensure deeper integration of DaCHS services into the KazVO web portal interface, improve the system and methods for storing VO data, and add a search service for searching registers and VO network data. It is also expected to significantly expand the range of astronomical data provided under IVOA protocols, in particular modern photometric and spectral data coming from FAI telescopes; it is also planned to publish our own catalogs and simulation data from a number of projects. In addition, an important innovation will be the publication of events generated by FAI services using the VOEvents protocol, as well as the publication of services for ordering observational and computing time as VO services.
2. Development of software for advanced analysis of catalogs and databases of ground-based and space observatories, using Data Mining algorithms, including cross-identification, search, determination of parameters of the object under study; The huge amounts of data available in the VO network require appropriate tools for searching and analyzing them. This task proposes the creation of several such tools, with an emphasis on FAI’s needs. In particular, it is planned to develop a service for processing spectral data using machine learning and artificial intelligence technologies, tools for multi-parameter aggregation of data from the VO network, as well as tools for unifying the local workflow with FITs files. Automation of data publication using VO protocols.
3. Implementation of the required International Virtual Observatory Alliance (IVOA) standards for interoperability with client frontends As part of this task, it is planned to introduce the VOSpace distributed storage protocol for observational data to ensure maximum reliability of data storage. In addition, it is planned to introduce the VOEvent protocol, which will allow us to listen to the target-of-opportunity events from many different sources, as well as send such events to the VO network. A separate task is the implementation of the SIMDAL protocol for providing and receiving unified access to simulation data.
