13:09:18 From Jason S : On this slide “Example current event”, what is the magnitude of the peak current density? (I assume units are microamps per m^2 ?) 13:09:47 From Frederick Wilder : There is a paper by Phan et al. where they have a formula whereby you can predict the electron temperature enhancement based on BL 13:10:33 From Frederick Wilder : GRL, 2013 13:10:41 From Prayash Sharma Pyakurel : doi:10.1002/grl.50917, 2013 13:34:27 From Tai Phan : I can answer Yi Hsin's question 13:41:13 From Prayash Sharma Pyakurel : We can discuss this at the end 13:42:36 From Julia Stawarz (she/her) : Yes, I agree and feel free to write something up in the chat as well if you would like to give people things to think about. 13:46:29 From M. Hasan Barbhuiya : @Drew Turner, Hi. In the region where you see electron remagnetization, what do the electron velocity distributions look like? 13:53:00 From Yi-Hsin Liu : Phan, yup~~ will like to know better about the selection criterion, during the discussion. 13:56:44 From Yi-Hsin Liu : Oops, I meant Tai. :P 13:57:40 From Richard Denton : Rick, can you tell if the whistlers are propagating in both directions? 13:58:33 From Frederick Wilder : I have not looked at that yet Richard - but it would be fairly simple to do! 13:59:02 From Richard Denton : I'm asking because of the presence of both beam and anisotropy. If driven by the anisotropy I think they should be going in both directions. 13:59:03 From Frederick Wilder : To expand on Naoki’s question - one thing that I forgot to mention is that whistler waves are seen all throughout the event, even far away from reconnecting current sheets 13:59:21 From Frederick Wilder : So the whistler waves may not necessarily be caused by reconnection 13:59:50 From Naoki Bessho : I see. Thanks! 14:00:48 From Frederick Wilder : But they *could* be caused by reconnection - it’s hard to tell - I’ve been doing more detailed analysis of the vdfs as well as cross-spacecraft comparisons, but that will have to wait for GEM :( 14:00:59 From Frederick Wilder : Richard - good point! 14:06:21 From Tai Phan : Yi Hsin, If the electron-only signatures are in an ion-scale current sheet, then one cannot tell the difference between crossing an ion diffusion region (close to the X-line) or electron-only reconnection. If the current sheet is of electron scale, then it would not be consistent with the IDR. More importantly, if standard (ion-coupled) reconnection were generally operating in the turbulent magnetosheath, the chance of crossing the exhaust would be much higher than crossing the IDR, but that does not seem to be the case in the statistics shown by Imogen and Julia. 14:11:57 From Owen Roberts : Hi Alex if I understood you are looking at the SDK something that is 'global' and comparing the power law index of the electron distribution. How are you calculating that the power law index, are you averaging distributions? Maybe you could look at 'local' quantities like LIM or PVI? 14:13:49 From Mojtaba Akhavan-Tafti : @Julia does your final slide/right plot indicate that the thinner CSs have stronger |J|? Thanks and great presentation! 14:14:12 From Alex Chasapis : @owen 14:14:53 From Alex Chasapis : I calculated the power-law index for every distribution and then for the comparison here used the average during each interval 14:16:04 From Julia Stawarz (she/her) : @Mojtaba I don’t think there was a clear correlation between the total current magnitude and the current sheet thickness. The figure was showing just the outflow speed (L component of the electron velocity) not the magnitude of all 3 components. 14:16:38 From Alex Chasapis : Yes a LIM type measure would be more appropriate for this comparison though 14:18:20 From William Matthaeus : @Mojtaba @Julia did the question pertain to the total integrated current or the peak current density? 14:19:12 From Julia Stawarz (she/her) : In my answer I was referring to the peak. 14:19:26 From Julia Stawarz (she/her) : The plot was also the peak outflow velocity 14:24:59 From Mojtaba Akhavan-Tafti : Thanks, @Julia! @Bill read my mind… It is interesting to determine how the CS total current (integrated value) compares across different reconnection events. 14:26:39 From Julia Stawarz (she/her) : @Mojtaba Yes, that is certainly something I could look at. 14:42:26 From Tak Chu Li : Tai, in the ion-scale current sheets, would it be possible that the development of ion jets is suppressed/weakened by pre-existing turbulent flows in the exhaust regions? On the other hand, I agree with San Lu that ion temperature could help to differentiate between EO and standard reconnection. 14:49:41 From Yi-Hsin Liu : Here is the observation of counter-streaming ions accelerated by Hall electric field within IDR by Wygant et al. 2005. I guess this could be used to distinguish regular vs. electron-only reconenction, if the MMS cross the diffusion region in the normal direction. https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2004JA010708 14:52:20 From Prayash Sharma Pyakurel : Thanks Yi-Hsin! 14:55:01 From Yi-Hsin Liu : Before people starts to disappear from this zoom. I like to announce the opening of postdoc position. :P https://apply.interfolio.com/85907 15:10:31 From Riddhi Bandyopadhyay : Thank you Julia and Prayash for organizing 15:10:44 From William Matthaeus : nice session!
