Interesting Astrophysics: Jan 12 - Jan 16

Another week, and another dose of preprints (and maybe some actual refereed papers too) that strike my fancy. There are a decent number of papers on or related to starbursts, and even a few papers that can be loosely considered as somewhat related to galactic winds as well, both of which are nice.

"Interesting Astrophysics" will return in two weeks time.

Galaxies and Starbursts

Magnetic structure of our Galaxy: A review of observations
J. L. Han, arXiv:0901.1165 [ps, pdf, other]
Comments: 10+1 pages. Invited Review for IAU Symp.259: Cosmic Magnetic Fields: From Planets, to Stars and Galaxies (Tenerife, Spain. Nov.3-7, 2009). K.G. Strassmeier, A.G. Kosovichev & J.E. Beckman (eds.)

Yes, I know this is very similar to the Han conference proceedings (arXiv:0901.0040) in last week's Interesting Astrophysics.

Cosmic-ray driven dynamo in the medium of irregular galaxy

Cluster magnetic fields from galactic outflows
J. Donnert, K. Dolag, H. Lesch and E. Müller, 2008, MNRAS, 392, 1008

Comments: 6 pages, 5 figures, proceedings to "Star-forming Dwarf Galaxies:
Ariadne's Thread in the Cosmic Labyrinth", Crete, 2008

I must take time out to read this at some point.

AGN and Black Holes

Kinematic and Excitation Structure of the NGC 1068 Narrow-Line Region
Shinobu Ozaki, arXiv:0901.1704 [ps, pdf, other]
Comments: 18 pages, 17 figures. Accepted for publication in PASJ

This has some nice-looking work on radiation-driven clouds, which I really should spend some time reading more carefully.
