IAR and the prospects of low frequency radio astronomy in South America
Abstract
The Instituto Argentino de Radioastronoma (IAR) was founded in 1962 as the first radio astronomy facility in Latin America. Nowaday,s it operates two 30-m radio telescopes used mainly for timing and continuum observations at 1.4 GHz. There is now a growing interes,t in the low-frequency radio window to the Universe, with the planning and implementation of pathfinders and new observatories aroun,d the world. IAR is contributing to these efforts with the Multipurpose Interferometer Array (MIA), a versatile low-frequency interf,erometer (100 MHz - 2 GHz) designed to investigate transient sources and non-thermal cosmic radiation from the Southern Hemisphere.,MIA is conceived as the future main facility to be operated by IAR. On the occasion of the institute s 60th anniversary, we propose,to gather in Buenos Aires city worldwide experts on low-frequency radio astronomy, both in science and technology.The conference is, designed to exchange and discuss ideas, experiences and research perspectives in this exciting field of astronomy. It will boost MI,A development and low-frequency radio science in the region. We expect that the meeting will result in the formation of new links an,d collaborations that will shape the future of radio astronomy in Argentina and South America. The meeting will consist of invited a,nd contributing talks, posters, and plenty of time for discussions. Electronic proceedings will be edited with the contributions so,a wide audience will benefit from the meeting. A visit to the facilities of IAR in Villa Elisa is also planned. This conference will, focus on a wide range of topics at the basic research level. Those topics include areas of research in astronomy such as fast radio, bursts, pulsar timing, active galactic nuclei, galactic non-thermal sources, the early universe. There will be presentations on the, latest research in these fields, as well as the necessary instrument design and algorithms work to perform high-speed data transfer, and process the data. These topics underlie topics in the Naval research strategy such as sensing and sense making for multi-domain, and multi-spectral sensors. Performing astronomical measurements at the necessary level of precision requires an understanding of t,he transmission of these frequencies through the atmosphere. Additionally, many advances in research areas of interest to the Navy s,uch as synthetic aperture radar and big data processing originate in the astronomy community, due to the large datasets and high-pre,cision measurements needed to probe the early universe.
