First ECHO paper

Our first paper about the drone calibrator is out on the arxiv today!  Using data from our field tests last year we measured the stability and accuracy of the beam maps. The repeatability compared well to measurements made using satellites (thats the plot on the right) and the measurements matched up well with the models. There were a few issues though. …

First map of MWA tile!

Last week the ECHO team took the (relatively) short drive from Tempe up to Prescott, Arizona and Embry Riddle Aeronautical University to do some more testing at a new location.  The Embry-Riddle Physics department has put together a very nice campus observatory which is predominantly devoted to radio science, both astronomy and aerospace. Under the leadership of Professor Andri …

ECHO Echo echo

This semester I start work in earnest on a new project thats been simmering in the background, the External Calibrator for Hydrogen Observatories (ECHO) an experimental method to provide an airborne calibration source for wide-field radio arrays observing Hydrogen at cosmological distances. In particular, accurate maps of the primary beam (the response of the receiver …
