Sparks: The Magellan/FIRE survey from starburst to post-starburst
Dalya Baron, David J. Setton, Yilun Ma +5
Rapid transitions from starburst to quiescence constitute a key evolutionary pathway in galaxy formation. Post-starburst galaxies trace this brief phase, exhibiting optical spectra…
The X-Ray Dot: Exotic Dust or a Late-Stage Little Red Dot?
Raphael E. Hviding, Anna de Graaff, Hanpu Liu +15
JWST's "Little Red Dots" (LRDs) are increasingly interpreted as active galactic nuclei (AGN) obscured by dense thermalized gas rather than dust as evidenced by their X-ray weakness…
The Discovery of Little Red Dots in the Local Universe: Signatures of Cool Gas Envelopes
Xiaojing Lin, Xiaohui Fan, Zheng Cai +25
JWST observations have revealed a population of high-redshift "little red dots" (LRDs) that challenge conventional AGN models. We report the discovery of three local LRDs at $z = 0…
The Balmer Break and Optical Continuum of Little Red Dots from Super-Eddington Accretion
Hanpu Liu, Yan-Fei Jiang, Eliot Quataert +2
The physical origin of Little Red Dots (LRDs)--compact extragalactic sources with red rest-optical continua and broad Balmer lines--remains elusive. The redness of LRDs is likely i…
What you see is what you get: empirically measured bolometric luminosities of Little Red Dots
Jenny E. Greene, David J. Setton, Lukas J. Furtak +27
New populations of red active galactic nuclei (known as ``Little Red Dots'') discovered by JWST exhibit remarkable spectral energy distributions. Leveraging X-ray through far-infra…
Counting Little Red Dots at with Ground-based Surveys and Spectroscopic Follow-up
Yilun Ma, Jenny E. Greene, David J. Setton +13
Little red dots (LRDs) are a population of red, compact objects discovered by JWST at . At , they are roughly 100 times more abundant than UV-selected quasars. However,…
