Radio sources associated with emission-line galaxies in the Bootes void

VLA 20-cm continuum observations of eight emission-line galaxies in the Bootes void are presented. Five of the eight galaxies have weak (0.7-4.4 mJy) and compact radio emission. The radio and optical properties of these galaxies are compared with those of Seyferts and starburst galaxies in an effort...

Zusammenfassung:VLA 20-cm continuum observations of eight emission-line galaxies in the Bootes void are presented. Five of the eight galaxies have weak (0.7-4.4 mJy) and compact radio emission. The radio and optical properties of these galaxies are compared with those of Seyferts and starburst galaxies in an effort to understand the origin and nature of galaxy activity in such an underdense region. It is concluded that the radio and optical properties of these galaxies are remarkably similar to those of active galaxies in richer cluster environments. (Author)
