Clumpy star formation and an obscured nuclear starburst in the luminous dusty z=4 galaxy GN20 seen by MIRI/JWST

A. Bik, J. Álvarez-Márquez, L. Colina +28

Dusty star-forming galaxies emit most of their light at far-IR to mm wavelengths as their star formation is highly obscured. Far-IR and mm observations have revealed their dust, ne…

The impact of environment on size: Galaxies are 50% smaller in the Fornax Cluster compared to the field

Nushkia Chamba, Matthew Hayes, The LSST Dark Energy Science Collaboration

Size is a fundamental parameter for measuring the growth of galaxies and the role of the environment on their evolution. However, the conventional size definitions used for this pu…

Nebular C IV 1550 Imaging of the Metal-Poor Starburst Mrk 71: Direct Evidence of Catastrophic Cooling

M. S. Oey, Amit N. Sawant, Ashkbiz Danehkar +10

We use the Hubble Space Telescope ACS camera to obtain the first spatially resolved, nebular imaging in the light of C IV 1548,1551 by using the F150LP and F165LP filters. These ob…

An almost dark galaxy with the mass of the Small Magellanic Cloud

Mireia Montes, Ignacio Trujillo, Ananthan Karunakaran +9

Almost Dark Galaxies are objects that have eluded detection by traditional surveys such as the Sloan Digital Sky Survey (SDSS). The low surface brightness of these galaxies ((…

UV-Bright Star-Forming Clumps and Their Host Galaxies in UVCANDELS at 0.5 z 1

Alec Martin, Yicheng Guo, Xin Wang +32

Giant star-forming clumps are a prominent feature of star-forming galaxies (SFGs) and contain important clues on galaxy formation and evolution. However, basic demographics of clum…
