Discovery of a Boxy Peanut Shaped Bulge in the Near Infrared
Abstract
We report on the discovery of a boxy/peanut shaped bulge in the highly inclined Seyfert 2 galaxy NGC 7582. The peanut shape is clearly evident in near infrared JHK images but obscured by extinction from dust in visible BVR images. This suggests that near-infrared imaging surveys will discover a larger number of boxy/peanut morphologies than visible surveys, particularly in galaxies with heavy extinction such as NGC 7582. If the peanut in NGC 7582 is the same age as the starburst, it would have formed quickly; on a timescale of less than sim 10^8 years.Keywords
