Title: Probing the Extraplanar Diffuse Ionized Gas Properties of M33
Abstract: In disk galaxies, extraplanar diffuse ionized gas layers have
important implications for the transfer of mass and energy between the
disk, halo, and intergalactic environment due to star formation
feedback. However, there is not yet enough evidence to determine
whether the dynamics of these layers are best described by equilibrium
or non-equilibrium models. While studies of the kinematics of these
layers have focused on high-inclination galaxies, understanding their
three-dimensional dynamics will require studies of their kinematics in
low- and moderate-inclination galaxies. Here, we propose SparsePak IFU
emission-line spectroscopy of the extraplanar diffuse ionized gas in the
nearby, moderately-inclined disk galaxy M33 ($D \sim 0.9$ Mpc; $i \sim
54^{\circ}$). We propose SparsePak IFU observations at low spectral
resolution ($R \sim 4000$) to enable future kinematic observations at
high spectral resolution ($R \sim 10000$) by verifying the detection of
diffuse ionized gas, determining pointings of particular interest, and
developing an effective approach to sky subtraction.
