MSA-3D: Rotation Curves and Dark Matter Fractions at z~0.5-1.7 with JWST/NIRSpec
Juan M. Espejo Salcedo, Danail Obreschkow, Karl Glazebrook +17
We present rotation curves and inner mass distributions for 30 star-forming galaxies at , observed with JWST/NIRSpec as part of the MSA-3D Cycle 1 survey. Combining spat…
JWST Spectroscopic Insights Into the Diversity of Galaxies in the First 500 Myr: Short-Lived Snapshots Along a Common Evolutionary Pathway
Guido Roberts-Borsani, Pascal Oesch, Richard Ellis +21
We investigate the nature and spectroscopic diversity of early galaxies from a sample of 41 sources at z>10 with JWST/NIRSpec prism observations. We compare the properties of stron…
Consistent Gas-Phase Temperatures and Metallicities from UV and Optical Nebular Emission: A Reliable Foundation from z=0 to Cosmic Dawn
Erin Huntzinger, Yuguang Chen, Tucker Jones +6
The rest-frame UV spectra of star-forming galaxies are increasingly important as they become one of the primary windows to probe the physical properties of cosmic dawn (z>8) galaxi…
Joint Optical and Infrared Observations of N and O Reveal the Dust-Obscured Gas in Haro 3
Yuguang Chen, Tucker Jones, Ryan L. Sanders +22
Accurate chemical compositions of star-forming regions are a critical diagnostic tool to characterize the star formation history and gas flows which regulate galaxy formation. Howe…
JWST & ALMA Joint Analysis with [OII]3726,3729, [OIII]4363, [OIII]88m, and [OIII]52m: Multi-Zone Evolution of Electron Densities at and Its Impact on Metallicity Measurements
Yuichi Harikane, Ryan L. Sanders, Richard Ellis +8
We present a JWST and ALMA detailed study of the ISM properties of high-redshift galaxies. Our JWST/NIRSpec IFU spectroscopy targeting three galaxies at detects key rest-fr…
MSA-3D: Uncovering Weak AGNs and Resolved Outflows in Disguise in Star-Forming Galaxies
Namrata Roy, Alaina Henry, Tucker Jones +11
We present spatially resolved rest-optical spectroscopy of 38 star-forming galaxies at 0.5 < z < 1.7 from the JWST/NIRSpec MSA-3D survey, which uses slit-stepping to build IFU-like…
