High-resolution radio observations of nonthermal sources in the Rho Ophiuchus dark cloud.
Abstract
A portion of the Rho Ophiuchus dark cloud has been mapped with the VLA to investigate a possible radio counterpart to the COS-B γ-ray source 2CG353+16. The stronger two of the three sources detected have 21-cm hydrogen column densities and morphologies consistent with extragalactic sources. There is no radio counterpart to the γ-ray source detected. This negative result supports the possibility that the γ rays are emitted by the bulk mass of the cloud.
