e-MERLIN is an array of seven radio telescopes across the UK, connected to a powerful central correlator at Jodrell Bank Observatory (JBO) and operated as a dedicated radio interferometer to produce high-resolution images. With a maximum baseline length of 220 km, e-MERLIN provides a unique capability for microJansky sensitivity radio imaging, spectroscopy, polarisation and astrometry at 0.01-0.15-arcsec resolution in broad frequency bands centres at 1.5, 5 and 22 GHz (L, C and K bands).
e-MERLIN is addressing a broad range of scientific questions with its unique combination of angular resolution and sensitivity crucial for understanding:
- the history of star-formation and black hole growth as galaxies evolve
- the physical processes which govern the formation of stars
- the modes of activity in nearby galaxies
- the energetic processes in relativistic outflows from jets generated by black holes and compact objects
The e-MERLIN/VLBI National Facility provides the UK contribution to the European VLBI Network (EVN), which links telescopes across Europe and China for observations at milliarcsecond resolution. The EVN and JIVE pages outline the scientific, operational and technical capabilities.
The Jodrell Bank Centre for Astrophysics hosts the e-MERLIN/VLBI National Facility.
