Interesting Astrophysics: Feb 01 to Feb 19, 2010

I have no time to provide commentary, so without further interruption here are the papers and preprints that I consider interesting that have appeared over the period Feb 01-19, 2010.Galaxies and StarburstsThe AGN properties of the starburst galaxy NGC 7582T.V. Ricci, J.E. Steiner, R.B. Menezes, A. Garcia-Rissmann, R. Cid Fernandes, arXiv:1001.5269 [ps, pdf, other]Comments: 1 page, 2 figures, to be published in the Proceedings of the IAU Symposium no. 267The stellar populations of the AGN/Starburst galaxy NGC7582T.V. Ricci, J.E. Steiner, R.B. Menezes, A. Garcia-Rissmann, R. Cid Fernandes, arXiv:1001.5271 [ps, pdf, other]Comments: 2 pages, 2 figures, to be published in the Proceedings of the IAU Symposium no. 262Their abstract: "NGC 7582 is defined as a Starburst/AGN galaxy, since its optical and X-Ray spectra reveal both characteristics. In this work, we show the results of a stellar population modeling in a datacube taken with the Gemini South telescope. We found that $\sim$ 90% of the light in the field of view is emitted by stars that are less than 1 billion years old. A strong burst occurred about $\sim$ 6 million years ago and has nearly solar metallicity. We also found a Wolf-Rayet cluster."Star Formation in the Outer Filaments of NGC 1275R.E.A. ...
