Tiivistelmä
I study the relation of galaxy interactions and their central B/P/X/bl structures. I use a sample of 1413 galaxies from Stripe 82 region chosen by their angular diameter. I create "postage stamp" images in i-band, multi-band and unsharp masked i-band for the identification of the different interaction types and central structures. I use my own observations as well as catalog data to find any significant relations between different parameters. I find 217 X-shapes and 49 barlenses. This is small amount of barlenses compared to previous studies. I suspect that the deficiency in barlenses is caused by a lack of depth and resolution. The most statistically significant difference between the interacting and non-interacting galaxies is that in Milky Way luminosity and brighter high-inclination galaxies there is X-shapes in half of the non-interacting galaxies, while among interacting galaxies there is X-shapes only in fifth of the bright, high-inclination galaxies.
