NGC 765 - A disturbed H I giant

We present H i spectral line and radio–continuum VLA data of the galaxy NGC765, complemented by optical and Chandra X-ray maps. NGC765 has the largest H i-tooptical ratio known to date of any spiral galaxy and one of the largest known H i discs in absolute size with a diameter of 240 kpc measured at a surface density of 2× 10 atoms cm −2. We derive a total H i mass of MH I = 4.7×10 M , a dynami...
