Ir observations of the peculiar galaxy arp220


Play all audios:

ABSTRACT Observations from IRAS (the Infrared Astronomical Satellite) have shown that the peculiar galaxy Arp220 (=IC4553) has extreme IR properties1. Its IR luminosity is 100 times greater


than normal spirals and nearly equals that of the most luminous Seyfert known, Mkn231. Its optical appearance suggests that it is either a recent merger or that it has a prominent central


dust lane. Soifer _et al._1 have discussed whether a starburst or a Seyfert nucleus can better explain their observations. We report here 20-, 350- and 760-µm observations which constrain


the mass and size of the emitting region and compare Arp220 with the archetypal starburst galaxy M82. Access through your institution Buy or subscribe This is a preview of subscription
