Identifying changing partial differential equations using Sampled Local WeakIdent
Wenbo Hao, Mengyi Tang, Sung Ha Kang
We propose Sampled Local WeakIdent (SLW-Ident), a framework for identifying changing governing equations from a single set of given data. Different from a typical approach of using…
Resolving the Unresolved Galactic Winds in Multi-phase Models. I. Methodology and Application
Xinfeng Xu, Drummond Fielding, Timothy Heckman +12
Galactic winds shape galaxy evolution; however, the outflowing gas is complex: it consists of multiple ionization phases, and its properties vary spatially. Therefore, methods that…
CLASSY XIII. Cutting through the Clouds - Comparing Indirect Tracers of Ionizing Photon Escape
Kaelee S. Parker, Danielle A. Berg, John Chisholm +25
The Epoch of Reionization (EoR) provides critical insights into the role of early galaxies in shaping the ionization state of the universe. However, because of the opacity of the i…
Kinematics of Circumgalactic O VI Gas and Disk Rotation of Star-forming Galaxies
Stephanie H. Ho, Crystal L. Martin, Hasti Nateghi +2
Quasar sightline observations reveal that low-ionization-state gas corotates with the galaxy disk and often at sub-centrifugal velocities, suggesting that the gas is spiraling towa…
CLASSY XII: Nitrogen Enrichment Shaped by Gas Density and Feedback
Karla Z. Arellano-Córdova, Danielle A. Berg, Matilde Mingozzi +25
We investigate the chemical evolution of N/O using a sample of 45 local star-forming galaxies (SFGs) from the CLASSY survey. This sample spans a wide range of galaxy properties, wi…
Exploring the mysterious high-ionization source powering [Ne V] in high-z analog SBS0335-052 E with JWST/MIRI
Matilde Mingozzi, Macarena Garcia Del Valle-Espinosa, Bethan L. James +19
Nearby blue compact dwarf galaxies (BCDs) share similar properties with objects from the Epoch of Reionization revealed by JWST, in terms of low stellar mass, low metallicity and h…
