J1432+158: the most distant giant quasar
A. K. Singal, C. Konar, D. J. Saikia
We present low-frequency, GMRT (Giant Metrewave Radio Telescope) observations at 333 and 617 MHz of the most-distant giant quasar, J1432+158, which is at a redshift of 1.005. The r…
An increased estimate of the merger rate of double neutron stars from observations of a highly relativistic system
M. Burgay, N. D'Amico, A. Possenti +10
The merger of close binary systems containing two neutron stars should produce a burst of gravitational waves, as predicted by the theory of general relativity. A reliable estimate…
Low frequency radio and X-ray properties of core-collapse supernovae
A. Ray, P. Chandra, F. Sutaria +1
Radio and X-ray studies of young supernovae probe the interaction between the supernova shock waves and the surrounding medium and give clues to the nature and past of the progenit…
A study of the Galactic star forming region IRAS 02593+6016 / S 201 in infrared and radio wavelengths
D. K. Ojha, S. K. Ghosh, V. K. Kulkarni +3
We present infrared and radio continuum observations of S 201 star forming region. A massive star cluster is observed in this region, which contains different classes of young stel…
Constraining the variation of fundamental constants using 18cm OH lines
Jayaram N. Chengalur, Nissim Kanekar
We describe a new technique to estimate variations in the fundamental constants using 18cm OH absorption lines. This has the advantage that all lines arise in the same species, all…
Detection of OH and wide HI absorption toward B0218+357
N. Kanekar, J. N. Chengalur, A. G. de Bruyn +1
We present deep GMRT OH and WSRT HI absorption spectra of the gravitational lens toward B0218+357. Both the 1665 MHz and 1667 MHz OH lines are clearly detected for the…
