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…

The SPHINX public data release. II. Using low-ionisation absorption lines and dust attenuation to predict Lyman continuum escape

Valentin Mauerhofer, Jérémy Blaizot, Thibault Garel +11

Low-ionisation state (LIS) absorption lines, such as SiII 1526, are widely used to trace the properties of the interstellar medium (ISM) in galaxies. These lines provide crucial in…

CLASSY XIV: The Nitrogen Exception -- Multi-Phase Enrichment and Feedback in High- Analogs

Bethan L. James, Valentina Abril-Melgarejo, Karla Z. Arellano-Córdova +13

We present a first-of-its-kind analysis of the metal content across two interstellar medium (ISM) phases in a sample of 31 local star-forming galaxies from the COS Legacy Archive S…

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…

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…

SDSS-IV MaStar: Quantification and Abatement of Interstellar Absorption in the Largest Empirical Stellar Spectral Library

Kate H. R. Rubin, Kyle B. Westfall, Claudia Maraston +6

We assess the impact of CaII 3934,3969 and NaI 5891,5897 absorption arising in the interstellar medium (ISM) on the SDSS-IV MaNGA Stellar Library (MaStar) and produce corrected spe…
