galaxy images

After—but totally unrelated to—my rant about IGM interactions, Jacqueline van Gorkom (Columbia) emailed me regarding the possibility of detecting with SDSS data the tidal features in spiral galaxies that are undergoing IGM interactions in Virgo! So I made her some images, including this one (below), of a galaxy that is plausibly interacting with the IGM in Virgo.

The image is tiny not because the galaxy is tiny (it is several arcminutes in size) but rather because the image is matched in coordinates (pointing, rotation, and scale) to an HI map that van Gorkom and collaborators have made.
