First e-EVN + e-MERLIN + SRT science
| Submitter: | Aard Keimpema and Benito Marcote |
| Description: | The e-VLBI session of 18/19 September 2018 was an important milestone. For the very first time e-MERLIN, participating with three outstations, and the 64-m Sardinia Radio Telescope (SRT, Sr), joined forces with the e-EVN in a successful e-VLBI science observation. The inclusion of the SRT not only increases UV coverage, but also adds a tremendous amount of collecting area to the e-EVN. e-MERLIN, an array of seven radio telescopes located in the UK with baselines ranging between 10 and 217 km, perfectly complements the longer baselines of the e-EVN. The combination of the arrays substantially increases their sensitivity to emission on a wide range of scales and will open up new science cases. Besides the Mark II station at Jodrell Bank (Jb), which is also a regular EVN station, the e-MERLIN outstations at Cambridge (Cm), Knockin (Kn), and Defford (De) participated in this e-VLBI session. The other participating stations were Medicina (Mc), Effelsberg (Ef), Hartebeesthoek (Hh), Onsala (O8), Tianma (T6), Torun (Tr) and Westerbork (Wb). All stations were correlated in real time using the EVN Software Correlator at JIVE (SFXC). The figure shows fringes between Medicina (Mc) and all other stations in the e-VLBI session (12 in total), including the three e-MERLIN outstations, and the SRT. In total three experiments were observed, all at L band frequency (18 cm), totalling 26.5 hours of observing time. Many thanks, and congratulations, to the technical teams at Sardinia, Jodrell Bank and JIVE. |
