Eight-meter-wavelength Transient Array (ETA)

Overview: The Eight-meter-wavelength Transient Array (ETA) is a joint project of Virginia Tech Departments of Electrical & Computer Engineering and Physics. ETA is a radio telescope array operating in the band 29-47 MHz that continuously monitors virtually the entire sky for transients from a variety of high-energy astrophysical phenomena including primordial black holes, gamma ray bursts, supernovae, and compact object mergers. It is supported through an NSF Advanced Techniques & Instrumentation (ATI) grant and was hosted at the Pisgah Astronomical Research Institute (PARI) near Balsam Grove, NC from 2005 through 2008. A new mobile version of ETA is currently under construction. ETA people at VT currently include: Steve Ellingson (ECE), Cameron Patterson (ECE), John Simonetti (Physics), and students.

Quick Primer on ETA: Start with our URSI NRSM presentation "Searching for Low Frequency Radio Transients Using ETA" or Kshitija Deshpande's thesis for a description of the instrument and it's capabilities. Sean Cutchin's dissertation has the most recent results. Then check out Publications and Reports for more details on specific topics.
