Radio Jet Feedback on the Inner Disk of Virgo Spiral Galaxy Messier 58

open access: yesThe Astrophysical Journal
Spitzer spectral maps reveal a disk of highly luminous, warm (>150 K) H _2 in the center of the massive spiral galaxy Messier 58, which hosts a radio-loud active galactic nucleus (AGN). The inner 2.6 kpc of the galaxy appears to be overrun by shocks from

Modeling the Radial Color Profile of M31

open access: yesOpen Astronomy, 2003
We present a preliminary study of a fragment of the radial color profile of the spiral galaxy M 31 in terms of 2-D model accounting for internal extinction in the disk. The two stellar population disk model was assumed.
