RUBIES: A Spectroscopic Census of Little Red Dots; All V-Shaped Point Sources Have Broad Lines
Raphael E. Hviding, Anna de Graaff, Tim B. Miller +16
The physical nature of Little Red Dots (LRDs) - a population of compact, red galaxies revealed by JWST - remains unclear. Photometric samples are constructed from varying selection…

Measuring Emission Lines with JWST-MegaScience Medium-Bands: A New Window into Dust and Star Formation at Cosmic Noon
Brian Lorenz, Katherine A. Suess, Mariska Kriek +23
We demonstrate the power of JWST-NIRCam medium-band photometry to measure emission line fluxes and study dust and star formation properties of galaxies at cosmic noon. In this work…

UNCOVER/MegaScience: No Evidence of Environmental Quenching in a z2.6 Proto-cluster
Richard Pan, Katherine A. Suess, Danilo Marchesini +22
Environmental quenching -- where interactions with other galaxies and/or the intra-cluster medium (ICM) suppress star formation in low-mass galaxies -- has been well-established as…
