Image simulations of highly magnified clumpy galaxies
Irene Mini, Massimo Meneghetti, Matteo Messa +5
We present ClumPyLen, a Python-based simulator designed to produce realistic mock observations of strongly lensed, high-redshift, clumpy star-forming galaxies. The tool models gala…
The Spatial Evolution of Star Clusters in NGC 628 with JWST
Anne S. M. Buckner, Ana Duarte-Cabral, Angela Adamo +23
We examine the spatial distribution of star clusters in NGC 628 using the statistical tool INDICATE to quantify clustering tendencies. Our sample, based on HST and JWST observation…
The Calibration of Short Wavelength Polycyclic Aromatic Hydrocarbon Emission as Star Formation Rate Indicators with JWST
