Termination shocks in reconnection outflow jets: constraints from radio & EUV observations and numerical simulations

Alexander Warmuth, Leibniz Instituite for Astrophysics Potsdam (AIP)

The existence of fast-mode termination shocks in reconnection outflow jets has been predicted by theory and supported by the observation of stationary type II - like radio sources in the decimetric-metric regime. These classical observations will be reviewed and then compared to more recent microwave observations of a possible termination shock. The emphasis will be on how the observations can be used to constrain the shock parameters. Then, recent results from UV spectroscopy that could be attributed to termination shocks will be set into the context. The various observational characteristics will then be compared to the results of stat-of-the-art numerical simulations. Finally, the possible role of termination shocks for particle acceleration will be discussed.
