<br class="">
We are happy to announce a workshop on the Warm Ionized Medium (WIM)
in Galaxies to be held at the Green Bank Observatory in Green Bank,
WV from October 6-9, 2019. A similar meeting was held twenty years
ago in Green Bank in September 1999, with many of the recipients of
this message in attendance. A summary of that meeting can be found
in PASP: <a class="moz-txt-link-freetext" href="https://iopscience.iop.org/article/10.1086/316537/pdf">https://iopscience.iop.org/article/10.1086/316537/pdf</a>.<br class="">
<br class="">
This workshop will provide ample time for discussion, several review
talks, and posters for ~50 participants. Registration will be open
between July 1 and August 1 at the following link:
<a class="moz-txt-link-freetext" href="https://greenbankobservatory.org/event-details/?ee=1880">https://greenbankobservatory.org/event-details/?ee=1880</a>. The
meeting will run from approximately 5 pm on Sunday, October 6
through 1 pm on Wednesday, October 9.<br class="">

<b class="">SCIENTIFIC RATIONALE:</b><br class="">
<br class="">
The warm ionized medium, also called diffuse ionized gas, is a major
component of the Galactic interstellar medium and is clearly
important in other galaxies as well. In the twenty years since our
previous workshop, understanding on the ionization, heating, cooling
and overall dynamics of this gas has remained challenging. With
several new Galactic surveys, the wealth of extragalactic data, and
the advances in theoretical and computational models in the past few
decades a workshop to reevaluate our understanding of the warm
ionized medium is timely.<br class="">
<br class="">
Below are some potential topics to be discussed:<br class="">
<br class="">
1. The WIM in our Galaxy<br class="">
2. The WIM in other Galaxies<br class="">
3. Optical/UV observations of the WIM<br class="">
a. H-alpha surveys<br class="">
b. He I, [NII], [SII], etc.<br class="">
4. Radio and sub-mm observations of the WIM<br class="">
a. pulsar observations (dispersion measure)<br class="">
b. radio recombination lines (emission measure)<br class="">
5. Infrared observations of the WIM<br class="">
a. fine-structure transitions ([CII], [NII], etc.)<br class="">
6. Theory<br class="">
a. ionization of the WIM<br class="">
b. distribution/dynamics of the WIM<br class="">
c. heating of the WIM<br class="">
7. Relationship to other ISM components<br class="">
<br class="">
<br class="">
<b class="">STRUCTURE OF THE WORKSHOP:</b><br class="">
<br class="">
In the tradition of past Green Bank Workshops the total number of
participants will be limited (~50 people) which allows for candid
discussions. The workshop will be held from Sunday evening to
Wednesday afternoon. Only a limited number of talks will be given
which will allow ample time for discussion. Talks given will focus
on new results and general reviews. There will be space and time
for poster presentations. The detailed schedule of the workshop,
including the date, the number of talks, the length of each talk,
etc., will be determined at a later date. There are no planned
proceedings for this workshop other than a review summary in PASP. <br class="">
<br class="">
Clear skies, and we hope to see you in Green Bank! Please feel free
to share this invitation with your students and collaborators.<br class="">
