Dust and gas power-spectrum in M33 (HERM33ES)
F. Combes, M. Boquien, C. Kramer +18
Power spectra of de-projected images of late-type galaxies in gas and/or dust emission are very useful diagnostics of the dynamics and stability of their interstellar medium. Previ…
Arp 220: A Post-Starburst Galaxy With Little Star Formation Outside of It's Nuclear Disks
R. Chandar, M. Caputo, S. Linden +8
The ultra-luminous infrared galaxy Arp2 20 is a late-stage merger with several tidal structures in the outskirts and two very compact, dusty nuclei that show evidence for extreme s…
