Optical spectroscopic identification of candidate counterparts to four INTEGRAL sources
Abstract
For the purpose of the identification of their nature, we selected 4 unidentified INTEGRAL sources from the 3rd IBIS catalogue (Bird et al., astro-ph/ 0611493) for which a single NVSS radio source within the IBIS/INTEGRAL error box is found. Observations on northern hemisphere sources were performed on 2006 October 2 with the `G.D. Cassini' 1.5m telescope of the Astronomical Observatory of Bologna located in Loiano (Italy), and on 2006 November 14 and 27 with the 1.8m `Copernicus' telescope of the Astronomical Observatory of Asiago (Italy).
