First e-VLBI observations of GRS1915+105
We present results from the first successful open call electronic very-long-baseline interferometry (e-VLBI) science run, observing the X-ray binary GRS 1915+105. e-VLBI science allows the rapid production of VLBI radio maps, within hours of an observation rather than weeks, facilitating a decision...

| description | We present results from the first successful open call electronic very-long-baseline interferometry (e-VLBI) science run, observing the X-ray binary GRS 1915+105. e-VLBI science allows the rapid production of VLBI radio maps, within hours of an observation rather than weeks, facilitating a decision for follow-up observations. A total of six telescopes observing at 5 GHz across the European VLBI Network (EVN) were correlated in real time at the Joint Institute for VLBI in Europe (JIVE). Constant data rates of 128 Mbps were transferred from each telescope, giving 4 TB of raw sampled data over the 12 hours of the whole experiment. Throughout this, GRS 1915+105 was observed for a total of 5.5 h, producing 2.8 GB of visibilities of correlated data. A weak flare occurred during our observations, and we detected a slightly resolved component of 2.7 × 1.2 ms with a position angle of 140°± 2°. The peak brightness was 10.2 mJy per beam, with a total integrated radio flux of 11.1 mJy. |
