5. Young, Ultraviolet-bright Stars Dominate Dust Heating in Star-forming Galaxies
In star-forming galaxies, dust plays a significant role in shaping the ultraviolet (UV) through infrared (IR) spectrum. ... Using three samples of galaxies observed with the Spitzer Space Telescope and our dusty radiative transfer model, we find that young stellar populations (on the order of 100 million years old) dominate the dust heating in star-forming galaxies, and old stellar populations (13 billion years old) generally contribute less than 20% of the far-IR luminosity. ...

It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

11. Seyfert galaxies
... By means of deep optical images obtained at the Special Astrophysical Observatory 6-m telescope it was discovered that some Seyfert galaxies that were earlier considered to be non-interacting objects displayed signatures of elongated tidal envelopes belonging to satellite debris. ... Our results suggest that statistic studies based on popular imaging surveys (for example SDSS) can lead to an underestimation of the fraction of minor mergers among galaxies with active nuclei (AGN). ...

17. Introduction
... This task is designed to produce colour plots, the displayed colour at any pixel being a function of the relative intensities in the supplied energy/wavelength bands. Although designed originally to display EPIC X-ray images, it can also be used to create false-colour plots from OM images. ... The created colour image may either be stored in one of the file formats accessible via the pgplot library, or as a 3-plane fits file, or as a ppm image. ...
