JWST Views of Extraplanar Gas and Dust in NGC891

I am involved in a Cycle 1 JWST program to use near- and mid-infrared data from JWST to measure the extraplanar gas and dust properties of the edge-on galaxy NGC891. Stay tuned for more updates about this project!

Extraplanar Diffuse Ionized Gas (eDIG) in Edge-On Galaxies

Levy et al. 2019

We directly and kinematically measure eDIG in a sample of edge-on CALIFA galaxies, and investigate the ionization and origin of this phase. Photometrically and kinematically detected eDIG is commonplace in these galaxies.

eDIG in Intermediate Inclination Galaxies

Levy et al. 2018

We use a novel method of comparing the molecular and ionized gas rotation curves to kinematically measure extraplanar diffuse ionized gas (eDIG) in intermediate inclination galaxies from the EDGE-CALIFA survey. We find that the majority of our sample shows evidence for eDIG, meaning this phase is ubiquitous in star-forming galaxies.
