Symposium S8
26-27 June 2019
Resolving the Ionized ISM
News:
Registration is now open for contributed talks and posters!
Aims and scope
The ionized interstellar medium
(ISM) plays a crucial role in the cycling of baryons within galaxy
disks. Newly formed massive stars inject radiative and mechanical
energy that serves to both trigger and suppress additional star
formation, and in their end phase chemically enrich the local
environment. These processes are traced through the ionized gas
emission lines, which provide diagnostic information on the physical
conditions (dynamics, chemical abundance, ionization state, density) of
the ISM. With the revolution in optical spectroscopy brought about by
the advent of many new integral field spectographs (e.g. MUSE, KCWI),
newly established large sample surveys (e.g. CALIFA, MaNGA, SAMI) and
planned upcoming emission line surveys (PHANGS, SDSSV/LVM, SIGNALS), we
can now resolve in detail the structure of the ionized ISM across many
galaxies in the Local Volume with a wealth of emission line diagnostics.
This allows us to connect the large scale galaxy environments (spiral
arm, interarm, bar) with the small scale (<100pc) physics.
This symposium aims to bring together Galactic and extragalactic
observers, as well as simulators and modelers, working at the sub-100 pc
scales that resolve individual HII regions and other ionization
structures. The two key topics we will address are mapping gas phase
metallicities (both across disks in 2D and within individual resolved
HII regions) and resolving the ionization structure of HII regions and
diffuse ionized gas. We will place these results in the context of
cutting edge simulations and photoionization models, and prepare for the
advances that will be enabled by future surveys.
