An alien flyover
| Submitter: | Oleg Smirnov |
| Description: | This is a simulation of a rapidly-moving source as would be seen by the VLA. The source starts at the center and moves to the bottom right in a straight line. The three frames correspond to apparent source motions of 0.1, 0.25, and 2.5 arcmin per hour. The observation time is 8 hours. MFS was used to make the images. Cognoscenti will recognize a slowly rotating instantaneous VLA point spread function (PSF). What are the chances that such an alien fly-over would be spotted by astronomers, rather than eliminated from the data as 'interference'? This simulation was produced by the attendees of the ongoing MeqTree Workshop, during only their second day of exercises. |
