A New Window on the Hα Luminosity Function and Star Formation Rate Density from 1.2 < z < 6.6 from JWST Medium-Band Photometry

Nicholas S. Martis, Chris Willott, Gregor Rihtaršič +23

We present the first self-consistent measurement of the Hα luminosity function over a wide redshift range, covering cosmic noon into the epoch of reionization. Our analysis utilize…

CANUCS/Technicolor Data Release 2: A Catalogue of Galaxy Structural Parameters in up to 29 HST+JWST bands and a Multi-Wavelength Exploration of the Galaxy Size-Mass Relation at

Maya Merchant, Lamiya A. Mowla, Georgios E. Magdis +23

We present James Webb Space Telescope (JWST) results of a morphological study of galaxies in the CAnadian NIRISS Unbiased Cluster (CANUCS) and Technicolor surveys, observed in 19 m…

A Population of Red Galaxies with Very Strong Emission Lines at Revealed by the NIRCam Medium Bands: ''Classic'' LRDs, Dusty Star-Forming Galaxies, and a Missing Population of LRDs

Sunna Withers, Adam Muzzin, Swara Ravindranath +16

The NIRCam medium-bands have proven to be efficient at identifying Emission Line Galaxies (ELGs) with high equivalent width (EW) H and [OIII]+H emission lines. In this pape…

Discovery of Ancient Globular Cluster Candidates in the Relic, a Quiescent Galaxy at

Katherine E. Whitaker, Sam E. Cutler, Rupali Chandar +31

Globular clusters (GCs) are some of the oldest bound structures in the Universe, holding clues to the earliest epochs of star formation and galaxy assembly. However, accurate age m…

GalSyn I: A Forward-Modeling Code for Synthetic Galaxy Observations from Hydrodynamical Simulations and First Data Release from IllustrisTNG

Abdurro'uf, Henry C. Ferguson, Samir Salim +9

We present GalSyn (Galaxy Synthesizer), a modular and flexible Python package for generating synthetic observations from hydrodynamical galaxy simulations. GalSyn generates synthet…

Finding the boundary: Using galaxy membership to inform galaxy cluster extent through machine learning

Christine Hao, Stephanie O'Neil, Mark Vogelsberger +3

The spatial extent of the environment's impact on galaxies marks a transitional region between cluster and field galaxies. We present a data-driven method to identify this region i…
