New Lessons from the HI Size-Mass Relation of Galaxies
Jing Wang, Bärbel S. Koribalski, Paolo Serra +4
We revisit the HI size-mass (D-M) relation of galaxies with a sample of more than 500 nearby galaxies covering over five orders of magnitude in HI mass and mo…
The Scale Height of NGC 1058 Measured from its HI Power Spectrum
Prasun Dutta, Ayesha Begum, Somnath Bharadwaj +1
We have measured the HI power spectrum of the nearly face-on spiral galaxy NGC 1058 from radio-interferometric observations using a visibility based estimator. The power spectrum i…
A search for HI in some peculiar faint dwarf galaxies
Ayesha Begum, Jayaram N. Chengalur
We present a deep Giant Metrewave Radio Telescope (GMRT) search for HI 21 cm emission from three dwarf galaxies, viz. POX 186, SC 24 and KKR 25. Based, in part, on previous single…
HI 21cm absorption in low z damped lyman-alpha systems
Nissim Kanekar, Jayaram N. Chengalur
We report Giant Metrewave Radio Telescope (GMRT) 21cm observations of two confirmed and one candidate low redshift damped Lyman-alpha systems (DLAS). HI absorption was detected in…
DI in the outer Galaxy
Jayaram N. Chengalur, Robert Braun, W. Butler Burton
We report on a deep search with the Westerbork Synthesis Radio Telescope towards the galactic anticenter for the 327 MHz hyperfine transition of DI. This is a favorable direction f…
