Mock Galaxy Surveys for HST and JWST from the IllustrisTNG Simulations
Gregory F. Snyder, Theodore Pena, L. Y. Aaron Yung +3
We present and analyze a series of synthetic galaxy survey fields based on the IllustrisTNG Simulation suite. With the Illustris public data release and JupyterLab service, we gene…
Morphological signatures of mergers in the TNG50 simulation and the Kilo-Degree Survey: the merger fraction from dwarfs to Milky Way-like galaxies
Alejandro Guzmán-Ortega, Vicente Rodriguez-Gomez, Gregory F. Snyder +2
Using the TNG50 cosmological simulation and observations from the Kilo-Degree Survey (KiDS), we investigate the connection between galaxy mergers and optical morphology in the loca…
Effects of feedback on galaxies in the VELA simulations: elongation, clumps and compaction
Daniel Ceverino, Nir Mandelker, Gregory F. Snyder +5
The evolution of star-forming galaxies at high redshifts is very sensitive to the strength and nature of stellar feedback. Using two sets of cosmological, zoom-in simulations from…
CEERS Key Paper III: The Diversity of Galaxy Structure and Morphology at z=3-9 with JWST
Jeyhan S. Kartaltepe, Caitlin Rose, Brittany N. Vanderhoof +58
We present a comprehensive analysis of the evolution of the morphological and structural properties of a large sample of galaxies at z=3-9 using early JWST CEERS NIRCam observation…
High Resolution HST Imaging Survey of Local Star-Forming Galaxies I: Spatially-Resolved Obscured Star Formation with H and Paschen- Recombination Lines
Clara Giménez-Arteaga, Gabriel B. Brammer, Danilo Marchesini +9
We present a sample of 24 local star-forming galaxies observed with broad- and narrow-band photometry from the Hubble Space Telescope, that are part of the GOALS survey of local lu…
Identifying Galaxy Mergers in Simulated CEERS NIRCam Images using Random Forests
Caitlin Rose, Jeyhan S. Kartaltepe, Gregory F. Snyder +23
Identifying merging galaxies is an important - but difficult - step in galaxy evolution studies. We present random forest classifications of galaxy mergers from simulated JWST imag…
