A metallicity-spin temperature relation in damped Lyman- systems
Nissim Kanekar, Alain Smette, Frank H. Briggs +1
We report evidence for an anti-correlation between spin temperature and metallicity [Z/H], detected at significance in a sample of 26 damped Lyman- absorbers (DLAs…
The HI gas content of galaxies around Abell 370, a galaxy cluster at z = 0.37
Philip Lah, Michael B. Pracy, Jayaram N. Chengalur +6
We used observations from the Giant Metrewave Radio Telescope to measure the atomic hydrogen gas content of 324 galaxies around the galaxy cluster Abell 370 at a redshift of z = 0.…
Probing Turbulence in the Interstellar Medium of Galaxies
Prasun Dutta, Ayesha Begum, Somnath Bharadwaj +1
The power spectrum of HI intensity fluctuation of the interstellar medium carries information of the turbulence dynamics therein. We present a method to estimate the power spectrum…
A Study of ISM of Dwarf Galaxies Using HI Power Spectrum Analysis
Prasun Dutta, Ayesha Begum, Somnath Bharadwaj +1
We estimate the power spectrum of HI intensity fluctuations for a sample of 8 galaxies (7 dwarf and one spiral). The power spectrum can be fitted to a power law P_HI(U) = A U^αfor…
HI in very metal-poor galaxies: the SBS 0335-052 system
B. Ekta, Simon A. Pustilnik, Jayaram N. Chengalur
We present Giant Metrewave Radio Telescope (GMRT), HI 21cm observations of SBS 0335-052E and SBS 0335-052W, a close pair of dwarf galaxies, which are further unusual in being the m…
Anomalous HI in NGC 2997
Kelley M. Hess, D. J. Pisano, Eric M. Wilcots +1
We present deep HI observations of the moderately inclined spiral galaxy, NGC 2997. The goal of these observations was to search for HI clouds in the vicinity of NGC 2997 analogous…
