Dear All,

I am currently writing an article on the halo and other cryptic ultra-faint outer features found in the outermost parts of NGC 253.

Apparently David Malin published an enhanced image of NGC 253, showing its faint outer light, in the 1981 Sky & Telescope.

The reference is ::

D.F. Malin, year 1981,
Sky & Telescope Magazine
Volume 62
Page 216

If anyone has a copy of this issue of S&T containing Malin's deep image of NGC 253, I would be eternally happy if you could provide me with a scan of the image!!

cheers,
Robert

Hi all . . .

I'd like to add the link to the paper Robert may have in mind in his call for the Malin image, Leroy et al 2014 (http://arxiv.org/abs/1411.2836) re. dense gas clouds near the core of nearby NGC 253 which are feeding massive starbursts there. Robert told me about this one, just as I had downloaded a brand-new paper issued just last month (http://arxiv.org/abs/1504.07239v1) about the same thing happening our own MW galaxy. This subjects of the goings-on in galaxy cores may be a bit arcane for we eyepiece warmers who can't see all the excitement due to all the dust, but it is a Big Deal among those folk who are trying to understand how and why our Milky Way and its friends are doing things they never dreamed possible. NGC 253 is an ideal place to look because it is relatively nearby and behaves a lot like our own galaxy. If the first paper cited above is a bit dense and thick (12 authors, surprise, all want their place in the sun), another paper published 10 years ago (http://arxiv.org/abs/astro-ph/0509430v1) describes the same phenomenon using the equipment they had then. =Dana in SA
