Abstract (from CDS):

Since its launch the INTEGRAL observatory has discovered a variety of hard X-ray sources in the Galactic plane. Using GMRT, we have made repeated observations of these sources to search for the radio counterparts of seventeen of them at low frequencies. The source positions were taken from the various ATEL and IAUC announcements reporting their discovery. Possible radio counterparts for seven of these sources, IGR J06074+2205, IGR J15479-4529, IGR J16479-4514, IGR J17091-3624, IGR J18027-1455, IGR J18539+0727 and IGR J21247+5058 were detected within 3σ of the positional uncertainty derived from the INTEGRAL observations. The offset in the radio position was calculated using the positions mentioned in the ATEL. We have also analyzed the available NVSS images for some of these fields at 1.4GHz along with our observations. In this paper we present the radio images and the best fit positions for the positive detections. The X-ray variability for some of the sources within the time scales of 100s to 1ks as seen in the RXTE/PCA light curves suggests their Galactic origin and possible binary nature. We discuss briefly the characteristics of these sources from the available information at different wave bands.
