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…
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…
Spatially Resolved Star Formation relations in local LIRGs along the complete merger sequence
M. Sánchez-GarcÃa, T. DÃaz-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…
