| An extreme scattering event caught in real time |
| by Keith Bannister (CASS) |
| These two panels show the multi-frequency
light curve (top) and corresponding dynamic spectrum (bottom) of an Extreme
Scattering Event, detected by the ATCA in 2014, and reported in Science
(Bannister
et al. 2016). The data comprise 104 spectra obtained over about 1 year
with approximately 3 day sampling. With these data, and complementary VLBI
data, we were able to rule out a number of ESE models, and compute a 1D cut
through the electron column density. Reference: Bannister et al. 2016, Science 351, 354 --- See also yesterday's ADAP. |
