October 6-9, 2019
Thank you for a great response to the workshop! The initial registration deadline has passed. The Science Organizing Committee is finalizing a talk and meeting schedule.
However, we do still have several spaces available for the workshop for poster presentations / general participants. You are welcome to continue registering for the meeting until we reach our 50-person limit. We will also stream the meeting to allow for remote participation. Instructions for this remote participation will be posted on this website closer to the meeting.
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. A summary of that meeting can be found in PASP: https://iopscience.iop.org/article/10.1086/316537/pdf.
This workshop will be provide ample time for discussion, several review talks, and posters for 50 participants. Registration will be open on this site between July 1 and August 1. Scientific rationale, proposed topics, and travel instructions can be found below.
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.
Topics to be discussed:
- The WIM in our Galaxy
- The WIM in other galaxies
- Optical/UV observations of the WIM
a. H-alpha surveys
b. He I, [NII], [SII], etc.
- Radio and sub-mm observations of the WIM
a. Pulsar and FRB observations
b. Radio recombination lines
c. Radio polarimetry
- Infrared observations of the WIM
a. Fine-structure transitions ([CII], [NII], etc.)
- Theory and simulations
a. Ionization of the WIM
b. Distribution and dynamics of the WIM
c. Heating of the WIM
- Relationship to other ISM components
- Future WIM surveys
Structure of the Workshop
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 the evening of Sunday, October 6 through the afternoon of Wednesday, October 9. 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 are no planned proceedings for this workshop other than a review summary in PASP.
The easiest way to get here is to follow the directions on our “Getting Here” page. Please do note that some GPS systems do not always give the best route to the Green Bank Observatory, and nothing beats the good old-fashioned paper map for navigation.
In the event of an emergency, the nearest hospital is the Pocahontas Memorial Hospital in Buckeye, WV.
Schedule for the Workshop
On 10/6/2019, we will begin poster set-up at 5:00 p.m. and run into the evening
The full schedule for the workshop is available now (via shared Google Doc). There will be space and time for poster presentations.
The workshop will end at 1:00 p.m. on 10/9/2019

The number of participants is limited to 50. The initial registration deadline has passed, but we will continue to accept registrations for participants or poster presentations. Once we reach 50 registrations, the system will stop accepting new registrations. As of the initial August 1st registration deadline, we had ~40 registrations.
There is a fee for this event set at $250 / person which will cover meals, lodging, and incidental expenses. The registration fee can be paid in person at the workshop in October or billed afterwards.
You will not be billed at the time of registration, so the amount due at registration is $0.00.
