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-…
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…
Nowhere Left to Hide: Uncovering All of the Massive Young Embedded Star Clusters in the Antennae with JWST
Rupali Chandar, Miranda Caputo, Paul Goudfrooij +15
The Antennae galaxies merger produces the brightest infrared emission of any galaxy within ~20 Mpc, mostly from intense star formation taking place in supergiant molecular cloud co…
Spatially Resolved Star Formation relations in local LIRGs along the complete merger sequence
M. Sánchez-García, T. Díaz-Santos, L. Barcos-Muñoz +25
We investigate the properties of the interstellar medium (ISM) at ~100 pc scales in a sample of 27 nearby luminous infrared galaxies (LIRGs) spanning the entire merger sequence. In…
SIMLA: The Spitzer Infrared Spectrograph Mapping Legacy Archive
Grant P. Donnelly, Cory M. Whitcomb, Lindsey Hands +9
We present the Spitzer/IRS Mapping Legacy Archive (SIMLA); a complete set of mid-infrared spectral cubes built from low-resolution mapping-mode fixed-target observations from Spitz…
JWST Observations of Starbursts: PAHs Closely Trace the Cool Phase of M82's Galactic Wind
Sebastian Lopez, Colton Ring, Adam K. Leroy +30
Stellar feedback drives multiphase gas outflows from starburst galaxies, but the interpretation of dust emission in these winds remains uncertain. To investigate this, we analyze n…
Resolving Emission from Small Dust Grains in the Blue Compact Dwarf II Zw 40 with JWST
Thomas S. -Y. Lai, Sara Duval, J. D. T. Smith +15
We present James Webb Space Telescope (JWST) Near Infrared Spectrograph (NIRSpec) and Mid-infrared Instrument (MIRI) integral-field spectroscopy of the nearby blue compact dwarf II…
Polycyclic Aromatic Hydrocarbons (PAHs) in the High-redshift Universe: Prospect of the PRIMA FIRESS low-resolution spectroscopy
Ilsang Yoon, Brandon Hensley, Thomas S. -Y. Lai +6
The integrated luminosity from the features of the polycyclic aromatic hydrocarbons (PAHs) exceeds the luminosity from atomic and molecular emission lines in the star-forming regio…
Detection of Deuterated Hydrocarbon Nanoparticles in the Whirlpool Galaxy, M51
B. T. Draine, Karin Sandstrom, Daniel A. Dale +29
Deuteration of hydrocarbon material, including polycyclic aromatic hydrocarbons (PAHs), has been proposed to account for the low gas-phase abundances of D in the interstellar mediu…
JWST Observations of Starbursts: Relations between PAH features and CO clouds in the starburst galaxy M 82
V. Villanueva, A. D. Bolatto, R. Herrera-Camus +22
We present a study of new 7.7-11.3 m data obtained with the James Webb Space Telescope Mid-InfraRed Instrument in the starburst galaxy M 82. In particular, we focus on the depen…
A Spectroscopically Calibrated Prescription for Extracting PAH Flux from JWST MIRI Imaging
Grant P. Donnelly, Thomas S. -Y. Lai, Lee Armus +24
We introduce a prescription for estimating the flux of the 7.7 micron and 11.3 micron\ polycyclic aromatic hydrocarbon (PAH) features from broadband JWST/MIRI images. Probing PAH f…
The Metallicity Dependence of PAH Emission in Galaxies I: Insights from Deep Radial Spitzer Spectroscopy
Cory M. Whitcomb, J. -D. T. Smith, Karin Sandstrom +9
We use deep Spitzer mid-infrared spectroscopic maps of radial strips across three nearby galaxies with well-studied metallicity gradients (M101, NGC 628, and NGC 2403) to explore t…
The Impact of an AGN on PAH Emission in Galaxies: the Case of Ring Galaxy NGC 4138
G. P. Donnelly, J. D. T. Smith, B. T. Draine +5
We present a focused study of radially-resolved varying PAH emission in the low-luminosity AGN-host NGC 4138 using deep Spitzer/IRS spectral maps. Using new model PAH spectra, we i…
Radio Jet Feedback on the Inner Disk of Virgo Spiral Galaxy Messier 58
Patrick M. Ogle, Ivan E. Lopez, Victoria Reynaldi +10
Spitzer spectral maps reveal a disk of highly luminous, warm (>150 K) H2 in the center of the massive spiral galaxy Messier 58, which hosts a radio-loud AGN. The inner 2.6 kpc of t…
Direct Far-Infrared Metal Abundances (FIRA) I: M101
C. Lamarche, J. D. Smith, K. Kreckel +12
Accurately determining gas-phase metal-abundances within galaxies is critical as metals strongly affect the physics of the interstellar medium (ISM). To date, the vast majority of…
