Decametric radio spectra of some galaxies in clusters

Subramanian, K. R; Sastry, Ch. V (Astronomical Society of Indian, 1988-12)

Observations of 12 radio sources identified with clusters of galaxies were made in 1983-84 with a decameter-wave radio telescope. The measured flux densities at 34.5 MHz are combined with other low frequency measurements ...
Measurements of compact radio source size and structure of cometary ion tails using interplanetary scintillation at 103 MHz

Janardhan, P (Astronomical Society of India, 1993)

The work contained in this thesis was carried out at the Physical Research Laboratory, Ahmedabad and describes observations of Interplanetary Scintillation (IPS), carried out since 1984, using a large 10,000 sq m dipole ...
Ooty synthesis radio telescope - Design and performance

Sukumar, S et. al. (Astronomical Society of Indian, 1988)

The principle, design and operational parameters of the Ooty synthesis radio telescope (OSRT) are described. It consists of thirteen elements including the Ooty Radio Telescope, which is divided into five parts. Operating ...
Receiver System for Two Ooty Synthesis Radio Telescope

Narayana, D. L; Venkatasubramani, T. L; Bagri, D. S (Astronomical Society of Indian, 1988)

This paper describes the receiver system of the 4 km Ooty synthesis radio telescope (OSRT), consisting of 13 elements operating at 327 MHz. Major subsystems of the receiver electronics are briefly discussed. A round-trip ...
