Strong rest-UV emission lines in a "little red dot" AGN at : Early SMBH growth alongside compact massive star formation?

Hollis B. Akins, Caitlin M. Casey, Danielle A. Berg +11

JWST has now revealed a population of broad-line AGN at characterized by a distinctive SED shape, with very red rest-frame optical and very blue rest-frame UV continuum. Whil…

Crimson Behemoth: a Massive Clumpy Structure Hosting a Dusty AGN at

Takumi S. Tanaka, John D. Silverman, Yurina Nakazato +40

The current paradigm for the co-evolution of galaxies and their supermassive black holes postulates that dust-obscured active galactic nuclei (AGNs) represent a transitional phase…

A photo-z cautionary tale: Redshift confirmation of COSBO-7 at z=2.625

Shuowen Jin, Nikolaj B. Sillassen, Jacqueline Hodge +21

Photometric redshifts are widely used in studies of dusty star-forming galaxies (DSFGs), but catastrophic photo- failure can undermine all redshift-dependent results. Here we re…

Dust in Little Red Dots

Caitlin M. Casey, Hollis B. Akins, Vasily Kokorev +5

JWST has revealed a ubiquitous population of ``little red dots'' (LRDs) at , selected via their red rest-frame optical emission and compact morphologies. They are though…

ACOSMOS: Measuring the cosmic dust-attenuated star formation rate density at

Benjamin Magnelli, Sylvia Adscheid, Tsan-Ming Wang +14

[Abridged] In recent years, conflicting results have provided an uncertain view of the dust-attenuated properties of star-forming galaxies (SFGs). To solve this, we used the…
