The JWST Advanced Deep Extragalactic Survey: Discovery of an Extreme Galaxy Overdensity at z = 5.4 with JWST/NIRCam in GOODS-S

The Astrophysical Journal
We report the discovery of an extreme galaxy overdensity at z = 5.4 in the GOODS-S field using James Webb Space Telescope (JWST)/NIRCam imaging from JADES and JEMS alongside JWST/NIRCam wide-field slitless spectroscopy from FRESCO.

IllustrisTNG in the HSC-SSP: No Shortage of Thin Disk Galaxies in TNG50

The Astrophysical Journal
We perform a thorough analysis of the projected shapes of nearby galaxies in both observations and cosmological simulations. We implement a forward-modeling approach to overcome the limitations in previous studies, which hinder accurate comparisons ...

Data-space Validation of High-dimensional Models by Comparing Sample Quantiles

The Astrophysical Journal Supplement Series
We present a simple method for assessing the predictive performance of high-dimensional models directly in data space when only samples are available.

On the Stellar Disk Vertical Scale Height of Edge-on Galaxies from S4G

The Astrophysical Journal
Disk galaxies viewed as thin planar structures resulting from the conservation of angular momentum of an initially rotating pregalactic cloud allow merely a first-order model of galaxy formation, but the presence of vertically extended structures has ...

A Study of the Merging Dwarf Galaxy VCC322

The Astrophysical Journal
Galaxy interactions and mergers can enhance or reduce star formation, but a complete understanding of the involved processes is still lacking. The effect of dwarf galaxy mergers is even less clear than their massive counterpart.
