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…
JWST Observations of Starbursts: A Young Bubble in NGC 253's Central Starburst
Kaitlyn E. Sheriff, Elisabeth A. C. Mills, Xinyu Mai +31
We present a multi-wavelength analysis of a young bubble in the nuclear starburst of NGC 253 using new JWST MIRI-MRS observations together with archival ALMA (100, 350, 690 GHz) an…
JWST Observations of Starbursts: Molecular Hydrogen Excitation and Disequilibrium in M82
Sara E. Duval, J. D. T. Smith, Alberto D. Bolatto +24
Emission from the pure rotational transitions of H traces warm molecular gas, providing insight into its temperature distribution and local heating conditions. We have extended…
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…
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…
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…
The Young Ages of 70 μm-dark Clumps Inferred from Carbon Chain Chemistry
Kadin Worthen, Brian E. Svoboda, David S. Meier +4
The physical conditions of the earliest environment of high-mass star formation are currently poorly understood. To that end, we present observations of the carbon chain molecules…
Spatially-resolved spectro-photometric SED Modeling of NGC 253's Central Molecular Zone I. Studying the star formation in extragalactic giant molecular clouds
Pedro K. Humire, Subhrata Dey, Tommaso Ronconi +29
Studying the interstellar medium in nearby starbursts is essential for understanding the physical mechanisms driving these objects, thought to resemble young star-forming galaxies.…
Turbulent Pressure Heats Gas and Suppresses Star Formation in Galactic Bar Molecular Clouds
Andy Nilipour, Juergen Ott, David S. Meier +6
The Central Molecular Zone (CMZ) of the Milky Way is fed by gas inflows from the Galactic disk along almost radial trajectories aligned with the major axis of the Galactic bar. How…
Neural Network Constraints on the Cosmic-Ray Ionization Rate and Other Physical Conditions in NGC 253 with ALCHEMI Measurements of HCN and HNC
Erica Behrens, Jeffrey G. Mangum, Serena Viti +15
We use a neural network model and ALMA observations of HCN and HNC to constrain the physical conditions, most notably the cosmic-ray ionization rate (CRIR, zeta), in the Central Mo…
JWST Observations of Starbursts: Massive Star Clusters in the Central Starburst of M82
Rebecca C. Levy, Alberto D. Bolatto, Divakara Mayya +25
We present a near infrared (NIR) candidate star cluster catalog for the central kiloparsec of M82 based on new JWST NIRCam images. We identify star cluster candidates using the F25…
JWST Observations of Starbursts: Cold Clouds and Plumes Launching in the M82 Outflow
Deanne B. Fisher, Alberto D. Bolatto, John Chisholm +28
In this paper we study the filamentary substructure of 3.3 m PAH emission from JWST/NIRCam observations in the base of the M82 star-burst driven wind. We identify plume-like sub…
Physical Properties of the Southwest Outflow Streamer in the Starburst Galaxy NGC 253 with ALCHEMI
Min Bao, Nanase Harada, Kotaro Kohno +19
The physical properties of galactic molecular outflows are important as they could constrain outflow formation mechanisms. We study the properties of the southwest (SW) outflow str…
The ALCHEMI atlas: principal component analysis reveals starburst evolution in NGC 253
Nanase Harada, David S. Meier, Sergio Martín +24
Molecular lines are powerful diagnostics of the physical and chemical properties of the interstellar medium (ISM). These ISM properties, which affect future star formation, are exp…
