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…

The use of OH "main" lines to constrain the variation of fundamental constants
Nissim Kanekar, Jayaram N Chengalur
We describe a new technique to measure variations in the fundamental parameters and , using the sum of the frequencies of cm-wave OH ``main'' lines. The techn…

The temperature of the WNM in the Milky Way
Nissim Kanekar, Ravi Subrahmanyan, Jayaram N. Chengalur +1
We report high spectral resolution Australia Telescope Compact Array HI 21 cm observations resulting in the detection of the warm neutral medium (WNM) of the Galaxy in absorption a…
