Matrix-Driven Quartic Overhauser (QOVR) Surfaces Structural Framework: Continuity Limitations, Computer Graphics Algorithms, and Software Implementation

Hakan Üstünel

This study introduces the spatial and analytical construction of the Quartic Overhauser (QOVR) surface generation framework designed to resolve boundary alignment and localized sha…

JWST absorption line spectroscopy with SPURS: ISM covering fractions and kinematics in individual galaxies at

Keerthi Vasan G. C., Peter Senchyna, Charlotte A. Mason +11

We present deep rest-ultraviolet (UV) spectra of six luminous -- 9 galaxies in the Abell-2744 field taken as part of the JWST Cycle 4 Large Program SPURS. The individual gala…

SPURS: Bursty Star Formation in an Extremely Luminous Weak Emission Line Galaxy at

Zuyi Chen, Daniel P. Stark, Charlotte A. Mason +8

JWST has revealed a population of super-luminous early galaxies with a volume density in excess of most expectations. The spectra reveal diverse properties: while some reveal stron…

SPURS: Evidence for Clumpy Neutral Envelopes and Ionized IGM Surrounding Little Red Dots in Abell 2744 from Ultra-Deep Rest-UV Spectroscopy

Mengtao Tang, Daniel P. Stark, Charlotte A. Mason +14

Rest-frame ultraviolet (UV) spectra of Little Red Dots (LRDs) often show Ly emission. Along with broad Balmer emission, LRDs are expected to produce broad Ly emission. Howe…

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…
