(2019, <a href="http://arxiv.org/abs/1901.01132" class="">http://arxiv.org/abs/1901.01132</a>). Stellar feedback modules including stellar winds, ionizing radiation, and supernovae are further documented in Wall’s thesis (https://www.dropbox.com/s/c0qh1no85y1jnxf/J_Wall-Thesis_final.pdf?dl=0) and a paper in preparation.

The SOC consists of Joshua Wall, Steven McMillan, and myself. We encourage attendance by early career researchers including students who might find it useful, and ask recipients of this announcement to distribute it further to potential attendees. <br class=""><br class="">There will be no fee for participation in this workshop, thanks to support from the CCA, including provision of daily breakfasts and lunches, and an evening reception on Wednesday.<br class=""><br class="">Please send expressions of interest in participation to Mordecai-Mark Mac Low (mordecai@amnh.org), with a short description of any particular research goals.
