radio telescope, scientific research institute / centre
GMRT (Giant Metrewave Radio Telescope), built and operated by the National Centre for Radio Astrophysics (NCRA) of the Tata Institute of Fundamental Research, India is located here. It is the world's largest
radio telescope at meter wavelengths. It consists of 30 antennas, each of 45m diametre, spread over a 28 km region and operating at wavelengths of 20cm, 49cm, 90cm, 128cm and 200cm. An increase in the frequency level of the Giant Metrewave Radio Telescope (GMRT) located in Narayangaon some 80 km from Pune will help astronomers observe the Universe better and improve the accuracy of research in radio astronomy.
A part of the upgraded facility will be inaugurated by Srikumar Banarjee, former chairman of the Atomic Energy Commission, on Engineers' Day on Tuesday.
The improved telescope will be able to observe objects in the Universe in a new frequency space which is not covered by any major observatory in the world,
The telescope range is being increased to provide seamless frequency coverage from 130 MHz to 1500 MHz. Astronomers can receive signals at any frequency in this range just like tuning a commercial radio receiver to listen to a station of our choice. This will allow exploration of new aspects of the Universe. The maximum bandwidth is being increased to 400 MHz from the existing 32 MHz which will lead to increased sensitivity.
The unit uses the latest analog and digital technologies, servo systems among others to enhance the telescope's performance and features, along with improvement in civil, electrical & mechanical infrastructure.
These improvements will make the telescope more versatile and improve its sensitivity by more than a factor of three, allowing new experiments and research of the cosmos, keeping the GMRT on the forefront of the field.
खोडद या गावी जगात दुसर्या क्रमांकाने शक्तिशाली समजली जाणारी एक महाकाय रेडिओ दुर्बीण आहे. ही दुर्बीण खगोलशास्त्राच्या निरीक्षणासाठी वापरली जाते.
डोळ्यांनी निरीक्षण करायच्या ऑप्टिकल दुर्बिणीने केलेल्या निरीक्षणांना मर्यादा असल्याने हल्ली खगोलशास्त्राच्या अभ्यासाठी रेडिओ दुर्बिणीचा वापर होतो. प्रत्येक ग्रह, तारा स्वतःमधून विविध तरंगलांबीच्या चुंबकीय लहरी सर्वत्र सोडतो. या लहरींच्या अभ्यासावरून त्या ग्रहाचे वा तार्याचे चांगल्या प्रकारे निरीक्षण करता येते. या लहरी पकडण्यासाठी रेडिओ दुर्बिणीचा वापर होतो. अशा दुर्बिणीमुळे इतर तरंगलांबींपेक्षा आखुड असलेल्या रेडिओ तरंगलांबीच्या(१ मीटर) लहरींचे संकलन व अभ्यास करणे सोईस्कर झाले.
