Search for interactions between ejections of GRS 1915+105 and its environment

Abstract

To unravel the effect of likely interactions between the energetic ejections of the galactic superluminal source GRS 1915+105 and its surrounding interstellar medium, we observed its environment. Two IRAS sources are symmetrically placed with respect to GRS 1915+105, and are aligned with the sub-arcsec ejections of this source. We analyzed these two sources IRAS 19124+1106 and IRAS 19132+1035 through near-infrared, millimeter and centimeter wavelengths. The evidence for these regions being interaction zones seems inconclusive.Comment: 4 pages, 3 figures, to appear in Proceedings of X-ray Astronomy '999 - Stellar Endpoints, AGN and the Diffuse Background, 2000.
