Feedback Discussion Circle {#feedback_discussion_circle}¶
Organizer:
Our goal is to discuss every aspect of feedback in galaxies, from star
formation, stellar and supernovae feedback, as well as connection with
IGM.
The content will be more like a journal club, where we discuss recent
papers dealing with feedback related issues. Important papers published
on feedback over the last years, especially review papers, are of course
of interest.
Obviously, we are all encouraged to present our own work when it is
related to the theme of feedback.
We can also have presentations (short) when one of us comes back from a
conference where feedback issues got addressed. Of course, all these
presentations etc…are meant to be informal.
Anyone aware of deadlines for proposal, conference, project (instrument,
research program, numerical tool etc…) that could be of interest is
encouraged to communicate.
When {#when}¶
Every other tuesday, from 11:30 to noon (30mn), in room Lavande (1st
floor)
Schedule {#schedule}¶
Next meeting is*tuesday Feb. 9th, 11:30am, room Lavande (1st floor).*
- During our kick-off meeting, we agreed that it would be good to start
by short (15mn max) introductions about how feedback is
understood/defined in our respective fields. Then we have 15mn to ask
questions and discuss.
We will start, by a 15mn review about stellar feedback (JCB),
illustrated by recent results.
Some News: {#some_news}¶
__Tuesday Feb. 9th:__ The first meeting took place this morning. The
pdf of the presentation on stellar feedback is available here:
stellar_feedback.pdf Our next meeting is scheduled on
Tuesday Feb. 23rd, room Tramontane (2nd floor). It would be good to have
an introduction on some different aspect of feedback. Any volunteer?
__Tuesday Feb. 23rd:__ It seems that most of the members of the
Feedback discussion circle could not make it for the meeting today. So
those of us who were present agreed that we should postpone the meeting
to the next schedule date, meaning Tuesday March 8th. This will give
everyone enough time to read the paper we were supposed to discuss:
http://arxiv.org/abs/1601.07559
__Tuesday March 8th:__We had a discussion about the paper originally
scheduled on Feb. 23rd. Related papers of interest for this topic of the
influence of single stars vs binaries in the context of reionization is
http://adsabs.harvard.edu/abs/2015MNRAS.453..960M Concerning the role
of binary models in spectral synthesis models
http://adsabs.harvard.edu/abs/2016MNRAS.457.4296W Next meeting is
scheduled for March 22nd.
__Tuesday April 19th:__ I presented a digest of a paper by P.
Crowther et al., about the massive stellar content of R136 in the LMC
(http://adsabs.harvard.edu/abs/2016MNRAS.458..624C),
where the origin of the HeII 1640\AA line is shown to be caused by the
very few, most massive stars in the cluster. A related paper to this is
http://arxiv.org/abs/1603.06974 where the same phenomenon is observed
in a blue compact dwarf galaxy (NGC 5253). Olivier Ilbert informed us
that next monday (Galaxy Evolution circle), Isabelle Pâris will present
a paper related to feedback by AGNs.
