GMRT(Giant Meterwave Radio Telescope)是位于印度的一个米波综合孔径射电望远镜,由30台45米口径天线组成,工作波段为0.2-6米,具有高灵敏度和广泛的观测范围,用于研究星系、脉冲星、射电源及太阳物理等领域。 GMRT:探索宇宙奥秘的巨型米波射电望远镜 GMRT的基本定义与全称 GMRT,全称为Giant Meterwave...
A Giant Metrewave Radio Telescope (GMRT) is being set up by TIFR as a National Facility at Khodad, near Narayangaon, 80 km north of Pune and 200 km east of Bombay. The academic headquarters of the GMRT is to be located in the University of Poona Campus....
We present Giant Metrewave Radio Telescope (GMRT) observations of redshifted HI 21cm absorption in two low redshift (z=0.2212, z=0.0912) damped Lyman-alpha systems seen towards the gigahertz peaked source OI 363 (z_em = 0.630). The object at z=0.0912 is the lowest redshift damped Lyman...
In this paper, we present the first low frequency (< 1.4 GHz) radio continuum study of a Wolf Rayet galaxy NGC 4214 using the Giant Meterwave Radio Telescope (GMRT). We detect diffuse extended emission from the galaxy disk at 325 MHz and find that the radio emission closely follows the ...
We summarise some of the works that have been carried out on the interstellar medium (ISM) with the Giant Metrewave Radio Telescope (GMRT) in the last few years. These include, (i) determination of the fraction of neutral hydrogen in unstable phase, (ii) turbulence in the ISM investigated...
Here we report on Giant MetrewaveRadio Telescope (GMRT) observations of a sample of steep spectrum sources fromthe 74 MHz VLSS survey. These sources are diffuse and not associated withnearby galaxies. Aims: The main aim of the observations is to search for diffuse radioemission associated with ...

3. Observations 3.1 The Giant Meterwave Radio Telescope The Giant Meterwave Radio Telescope (GMRT) consists of 30 fully steerable dishes, of diameter 45 m with a maximum baseline of 25 km (Swarup et al, 1991). The aperture efficiency of the dishes is ∼ 40% in the 21cm band, which ...
摘要: Here we present the traditional Observatory Report from the Giant Metrewavelength Radio Telescope (GMRT), where we highlight the recent events and news from the observatory, including usage statistics and new results with the GMR, as well as some recent improvements made to the telescope....
The Giant Metrewave Radio Telescope (GMRT) is today a major international radio astronomy facility that has produced several exciting new results since it was commissioned about 10 years ago. The GMRT is presently undergoing a major upgrade that will improve its senstivity by a factor of upto th...
