Warped Disk of Galaxy UGC 3697

The “Integral Sign” galaxy, UGC 3697 is an edge-on spiral galaxy with an unusually pronounced warp in both its stellar and gaseous disks. The neutral Hydrogen gas, represented in blue, is overlaid on an optical image of the stars of the galaxy. Unlike in normal spiral galaxies, the brightest concentration of neutral Hydrogen is not found near the center of UGC 3697 but along its western edge, where the Very Large Array (VLA) has detected a bright, extended region of emission. In addition, plumes of gas extend to considerable height above and below the disk of the galaxy.

The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.
	Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
	The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."
	AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
