The Next Generation Low Band Observatory

Friday October 27, 2017
3:30 pm


 Presenter:  Gregory Taylor, UNM, Physics and Astronomy
 Series:  Physics and Astronomy Colloquium
 Abstract:  Over the past decade there has been a resurgence in radio astronomy at low frequency (>300 MHz) with several new telescopes constructed and others being designed. The University of New Mexico currently operates the Long Wavelength Array (LWA) which consists of two dipole arrays of 256 elements each separated by 70 km in central New Mexico. An affiliated dipole array, the OVRO-LWA, is located in the Owens Valley in California and is operated by Caltech. We have also partnered with the National Radio Astronomy Observatory (NRAO) to add a new low frequency receiver system to the the Very Large Array (VLA). Using this new system we have demonstrated successful joint operation of the VLA and the two LWA stations in New Mexico to form the Expanded LWA (ELWA). Scientific results from these instruments have been encouraging with 44 LWA-related publications produced over the past 5 years covering a range of topics from studies of pulsars, planets, searches for exo-planets, meteors, solar and space weather, ionosphere/atmospheric studies, 21 cm cosmology, and most recently, searches for electromagnetic counterparts to gravitational wave events.

Given all the interest in science at low frequencies, we are proposing to partner with NRAO in order to deploy the 50-station Next Generation Low Band Observatory (ngLOBO). This will be carried out as an integral part of the Next Generation Very Large Array currently being designed as a 10-fold increase in sensitivity and resolution over the existing Very Large Array. I will provide some context and outline how the community can realize a great leap forward in scientific capability at low frequencies with ngLOBO.

Refreshments will be available before the colloquium, at 03:15 pm, in in the lobby of Dane Smith Hall.
