A Supernova factory in the merger system Arp 299

  title={A Supernova factory in the merger system Arp 299},
  author={Susan Gale Neff and James Scott Ulvestad and Stacy H. Teng},
  journal={The Astrophysical Journal},
We have imaged the nearby galaxy merger Arp 299 at arcsecond and milliarcsecond resolution, using both the Very Large Array (VLA) and the Very Long Baseline Array. The large-scale radio emission from the merger contains five bright, compact radio sources embedded in diffuse emission, with diameters less than 200 pc. Supernova rates of 0.1-1 yr-1 are required to produce the VLA-detected radio emission in these sources. Two of the compact VLA radio sources, designated source A and source D, have… Expand
Radio Emission from Young Supernovae and Supernova Remnants in Arp 299

Serendipitous discovery of the long-sought active galactic nucleus in Arp 299-A
Context. The dusty nuclear regions of luminous infra-red galaxies (LIRGs) are heated by either an intense burst of massive star formation, an active galactic nucleus (AGN), or a combination of both.Expand

Core collapse supernovae and starbursts
Core-collapse supernovae are the endproducts of massive stars, and yield radio events whose brightness depends on the intensity of the interaction experienced by the supernova ejecta with theExpand
Optical detection of the radio supernova SN 2000ft in the circumnuclear region of the luminous infrared galaxy NGC 7469
