JWST Observations of Starbursts: The motion of dust - PAH kinematics of M82 and NGC 253 with JWST/MIRI spectroscopy
Fergus R. Donnan, Karin Sandstrom, Alberto D. Bolatto +27
We present an analysis of dust kinematics in the local starburst galaxies M82 (NGC 3034) and NGC 253 using Polycyclic Aromatic Hydrocarbon (PAH) features observed with JWST/MIRI sp…
The Lifecycle and Emission Properties of PAHs in Cosmological Hydrodynamic Galaxy Formation Simulations
Desika Narayanan, Paul Torrey, Massimiliano Parente +16
We present the first cosmological model for the lifecycle and luminous properties of PAHs in galaxies as they evolve from z=6-->0. We model 40 zoom-in galaxies, coupled with an on-…
Survival of very small carbonaceous dust grains in the inner-CGM of NGC 891 from JWST/MIRI MRS
Jérémy Chastenet, Ilse De Looze, Karl D. Gordon +26
We present new spectroscopic observations of the inner circumgalactic medium (CGM) of NGC 891 taken with the Mid-Infrared Imager/Medium Resolution Spectroscopy instrument onboard J…
JWST Observations of Starbursts: Dust Processing in the M82 Superwind
Serena A. Cronin, Alberto D. Bolatto, Helena M. Richie +39
We present JWST MIRI and NIRCam imaging of the inner ~5 kpc of the M82 superwind at 0.05-0.375'' (~0.9-6.5 pc) resolution. Targeted filters probe emission from polycyclic aromatic…
Effects of Numerical Resolution on Simulated Cloud-Wind Interactions
Hannah Leary, Helena M. Richie, Evan Schneider
Mixing by hydrodynamical instabilities plays a key role in cloud-wind interactions, causing cloud destruction in the adiabatic limit and facilitating cloud survival with efficient…
PAH Emission Spectra and Band Ratios for Arbitrary Radiation Fields with the Single Photon Approximation
Helena M. Richie, Brandon S. Hensley
We present a new method for generating emission spectra from polycyclic aromatic hydrocarbons (PAHs) in arbitrary radiation fields. We utilize the single-photon limit for PAH heati…
Dust Evolution in Simulated Multiphase Galactic Outflows
Helena M. Richie, Evan E. Schneider
We present the first large-scale, high-resolution simulations of dusty, star formation feedback-driven galactic outflows. Using the Cholla hydrodynamics code, we investigate dust s…
Resolution Dependence of Cloud-Wind Simulations
Hannah J. Leary, Evan Schneider, Helena M. Richie
Using a set of wind-tunnel simulations, we investigate the effect that numerical resolution has on cloud evolution and acceleration. We also consider the role of wind speed in both…
JWST MIRI and NIRCam observations of NGC 891 and its circumgalactic medium
Jérémy Chastenet, Ilse De Looze, Monica Relaño +37
We present new JWST observations of the nearby, prototypical edge-on, spiral galaxy NGC 891. The northern half of the disk was observed with NIRCam in its F150W and F277W filters.…
Dust Survival in Galactic Winds
Helena M. Richie, Evan E. Schneider, Matthew W. Abruzzo +1
We present a suite of high-resolution numerical simulations to study the evolution and survival of dust in hot galactic winds. We implement a novel dust framework in the Cholla hyd…
Disk Instabilities Caused the 2018 Outburst of AG Draconis
Helena M. Richie, W. M. Wood-Vasey, Lou Coban
Symbiotic binary AG~Draconis (AG~Dra) has an well-established outburst behavior based on an extensive observational history. Usually, the system undergoes a 9--15~yr period of quie…
