e-MERLIN/VLBI National Facility


e-MERLIN requests proposals from the international astronomical community for observations to be made during Cycle-4. Proposals are competitively peer-reviewed under standard STFC rules by the PATT e-MERLIN Time Allocation Committee. Allocation will be made on the basis of scientific merit and technical feasibility alone. During e-MERLIN operations ~50% of observing time has been allocated to large legacy projects and most of the remaining time will be allocated via PATT to standard proposals solicited prior to each observing semester.

e-MERLIN provides high resolution (12-150mas) and high sensitivity (~[7]-14 microJy [inc. Lovell Telescope] in Cycle-4) imaging at cm wavelengths as well as polarimetry, spectroscopy and astrometry. Cycle-4 observations will commence in September 2016.

Developments during Cycle-4:Following testing and commissioning, the introduction of the full 2GHz bandwidth at C and K-Band is scheduled for delivery during the Cycle-4 observing period*. PATT observations made after this development may benefit from this extra bandwidth once it becomes available, however, this will be offered initially on a shared-risk basis. All proposals should be justified assuming the current available bandwidth of 512MHz. K-Band observations are also offered on a best-efforts basis. New K-Band receivers with improved sensitivity are being installed during Cycles 3 and 4.
