Multiphase Analysis of (U)LIRG Nuclear Activity (MAUNA). I. Spatially Resolved Optical Emission-Line Diagnostics

Justin A. Kader, Vivian U, Marina Bianchin +33

We present resolved optical integral-field spectroscopy of the 32 luminous and ultraluminous infrared galaxy systems of the Multiphase Analysis of (U)LIRG Nuclear Activity (MAUNA)…

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…

Star Formation and Nebular Attenuation from Pa, Br, and Br in Massive Dust-obscured Galaxies at Cosmic Noon using JWST

Virginia Vanicek, Jed McKinney, Alexandra Pope +14

Near-infrared hydrogen recombination lines can provide robust star-formation rates if the effects of dust attenuation continue to diminish towards longer wavelengths. To quantify n…

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/NIRSpec Reveals Diverse Nuclear Environments in Dwarf Galaxies Hosting AGN

Thomas Bohn, Archana Aravindan, Gabriela Canalizo +18

Dwarf galaxies, in the CDM framework, are expected to dominate the galaxy number density at all redshifts. As such, studying AGN in these systems, including characterizing their…

The HII Regions' Molecular Law of Star Formation

Daniela Calzetti, Drew Lapeer, Robert C. Kennicutt +28

We combine imaging data from the HST, JWST, and ground-based millimeter facilities to investigate the correlation between star formation rate (SFR) and molecular gas at the ~100 pc…
