Implications of Broad [O III] 4364 and UV Line Emission in Two Little Red Dots at z ~ 7 - 8
Casey Papovich, Kaila Ronayne, Weida Hu +17
We present deep, NIRSpec G140M and G395M spectroscopy of Little Red Dots (LRDs) at z = 6.68 and z = 8.35. Both LRDs show broad Balmer and [O III] 4364 emission. The broad [O III…
Deep Spectroscopic Follow-Up of Maisie's Galaxy -- A Typical Galaxy in the Early Universe
Rebecca L. Larson, Taylor A. Hutchison, Steven L. Finkelstein +26
The first several years of JWST observations have yielded surprisingly large numbers of bright galaxies, with follow-up spectroscopy of many of these sources implying extrem…
JWST COSMOS-3D: Spectroscopic Census and Luminosity Function of [O III] Emitters at 6.75<z<9.05 in COSMOS
Romain A. Meyer, Feige Wang, Koki Kakiichi +38
We present a catalogue of spectroscopically selected [OIII]+Hb emitters at 6.75<z<9.05 and the resulting [OIII] 5008 Ã Luminosity Function (LF) in the COSMOS field. We leverage the…
COSMOS-Web: does halo mass alone shape the clustering of star-forming and quiescent galaxies?
Louise Paquereau, Clotilde Laigle, Henry Joy McCracken +29
While stellar mass correlates strongly with halo mass, it remains unclear whether halo mass alone governs galaxy star-formation activity, or whether secondary halo properties and e…
Hunting Wandering 3<z<8 Black Holes: Spatial Offsets in Ionization Ratio and Continuum Emission
Urvi Thakurdesai, Anthony J. Taylor, Steven L. Finkelstein +14
The early growth and assembly of supermassive black holes (SMBHs) remain key topics of interest in galaxy evolution. One of the scenarios predicted by theoretical models is that fr…
Dust in the Average Galaxy: Attenuation, Emission, and Opacity from
Caitlin M. Casey, Hollis B. Akins, Andrew J. Battisti +43
We present constraints on the dust emission and attenuation properties of galaxies across 0<z<7 using JWST imaging from the COSMOS-Web Survey combined with deep FIR/(sub)millimeter…
