The Importance of Dust Distribution in Ionizing-photon Escape: NIRCam and MIRI Imaging of a Lyman Continuum-emitting Galaxy at z ∼ 3.8

The Astrophysical Journal Letters
We present deep JWST/NIRCam and MIRI imaging of Ion1, a previously confirmed Lyman continuum (LyC)-emitting galaxy at z _spec  = 3.794. Together with existing Hubble Space Telescope imaging, these new observations from the JWST Advanced Deep ...

New Observational Recipes for Measuring Dynamical States of Galaxy Clusters

The Astrophysical Journal
During cluster assembly, a cluster’s virialization process leaves behind signatures that can provide information on its dynamical state. However, no clear consensus yet exists on the best way to achieve this.

CLASSY. X. Highlighting Differences between Partial Covering and Semianalytic Modeling in the Estimation of Galactic Outflow Properties

The Astrophysical Journal
Feedback-driven massive outflows play a crucial role in galaxy evolution by regulating star formation and influencing the dynamics of surrounding media. Extracting outflow properties from spectral lines is a notoriously difficult process for a number of ...

Comparing Inside-out and Outside-in Quenching Modes in MaNGA Observation and MaNGIA Simulation

The Astrophysical Journal
This study probes the inside-out and outside-in quenching status of galaxies to understand the internal and external quenching sources responsible and their roles in galaxy evolution.
