2 Very Large Array What is it? Located in Southern New Mexico at 2100 m altitude Composed of 27 antennas (25 meters) reconfigurable on baselines 35m (Darray) to 36km (A-array, 1 arcsecond resolution at 1.4 GHz). Changes happen every ~4 months.
3 Very Large Array 1972 Approved by Congress 1975 First Antenna put into place 1980 Full science operations ($80 million) 2001 Complete electronics upgrade approved by NSF 2012 Jansky VLA full science operations

6 Radio Astronomy Powerhouse Present from 1980 to The Success Present of the VLA ~12,000 refereed papers with ~500,000 citations ~500 PhD theses The VLA has been among the most productive telescopes ever!
7 Karl G. Jansky Very Large Array (JVLA) Full frequency coverage from 1 to 50GHz. Provided by 8 wide frequency bands with cryogenic receivers. Up to 8GHz instantaneous bandwidth per polarization. New WIDAR correlator. Designed, funded, and constructed by Canada (HIA/DRAO). Unprecedented flexibility in matching resources to attain science goals. Noise-limited, full field imaging in all Stokes parameters for most observational fields. New software for telescope operations, etc. Credit: van Moorsel
