WALLABY pilot survey: Blinded by the light -- discovery of a fourth member in the ESO 179-013 system

Rayssa Guimarães Silva, Marco Grossi, Denise R. Gonçalves +12

We present new ASKAP/WALLABY HI observations of the nearby dwarf galaxy system ESO 179-013 (Kathryn's Wheel), the nearest known collisional ring galaxy, located 10 Mpc away in the…

A Morphology Catalog of Galaxies in CEERS: Evolution in the Size and Color Gradients of Galaxies Since Cosmic Dawn

Elizabeth J. McGrath, Steven L. Finkelstein, Guillermo Barro +42

We present measurements of morphological parameters from fitting 53,885 galaxies detected to a magnitude limit of F356W in the CEERS NIRCam imaging with galfit in six broad…

Direct Abundance Maps and Radial Metallicity Gradients of two Galaxies at z~4-5 in the GARDEN Survey

L. Stanghellini, S. A. Kassin, C. Pacifici +26

We investigate galaxies in the GARDEN (Galaxies at All Redshifts Deciphered and Explained with the NIRSpec MSA) survey that exhibit auroral emission lines, enabling spatially resol…

HELM's deep: Highly Extincted Low-Mass galaxies seen by JWST

L. Bisigello, G. Gandolfi, A. Grazian +25

The dust content of star-forming galaxies is generally positively correlated with their stellar mass. However, some recent JWST studies have shown the existence of a population of…

Beyond the Monsters: A More Complete Census of Black Hole Activity at Cosmic Dawn

Madisyn Brooks, Jonathan R. Trump, Raymond C. Simons +19

JWST has revealed an abundance of low-luminosity active galactic nuclei (AGN) at high redshifts (), pushing the limits of black hole (BH) science in the early Universe. Resu…

statmorph-lsst: Quantifying and correcting morphological biases in galaxy surveys

Elizaveta Sazonova, Cameron R. Morgan, Michael Balogh +16

Quantitative morphology provides a key probe of galaxy evolution across cosmic time and environments. However, these metrics can be biased by changes in imaging quality - resolutio…
