Little Red Dots as Intermediate Mass, Super-Eddington Engines: Insights from Type IIn Supernovae and The 1837-1856 Great Eruption of Carinae
Rohan P. Naidu, Jorryt Matthee, Anna de Graaff +20
JWST's Little Red Dots (LRDs) display a unique constellation of features that do not occur simultaneously in any other class of galaxies or AGN. Here we observe that many of these…
Black Hole Stars Across the Universe: Identifying Central Engine Dominated Little Red Dots at
Andrea Weibel, Rohan P. Naidu, Pascal A. Oesch +16
Photometric selections of Little Red Dots (LRDs) largely rely on identifying their ``V-shaped'' spectral energy distribution (SED). Recent work suggests this V-shape stems from a c…

Stellar masses of optically dark galaxies: uncertainty introduced by the attenuation law and star-formation histories
Yash Lapasia, Sandro Tacchella, Francesco D'Eugenio +11
Recent studies using JWST have suggested that some high-redshift galaxies may be ultra-massive, thereby challenging standard models of early galaxy formation. We analyse the stella…
