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…

Feedback and dynamical masses in high- galaxies: the advent of high-resolution NIRSpec spectroscopy

A. Saldana-Lopez, J. Chisholm, S. Gazagnes +11

Stellar feedback is an essential step in the baryon cycle of galaxies, but it remains unconstrained beyond Cosmic Noon. We study the ionized gas kinematics, dynamical mass and gas-…

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…

The Pitfalls of Using Lyman Alpha Damping Wings in High-z Galaxy Spectra to Measure the Intergalactic Neutral Hydrogen Fraction

Mason Huberty, Claudia Scarlata, Matthew J. Hayes +1

The Lyman Alpha damping wing is seen in absorption against the spectra of high-redshift galaxies. Modeling of this wing is a way to measure the volume neutral hydrogen fraction of…

A negligible contribution of two luminous ~ 7.5 galaxies to the ionizing photon budget of reionization

S. Gazagnes, J. Chisholm, R. Endsley +12

We present indirect constraints on the absolute escape fraction of ionizing photons () of the system GN 42912 which comprises two luminous galaxies ($M_{\rm…
