The THRILS Factor: Investigating the properties of Little Red Dots (LRDs) at 3<z<6 with JWST/NIRSpec
Ananya Ganapathy, Rebecca L. Larson, Erini Lambrides +20
JWST has uncovered a class of objects called LRDs, whose nature is still widely debated. In this work, we present a comprehensive spectroscopic analysis of nine LRDs in the Extende…
The Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
C3PO: A Lyα Emitting Galaxy at
Weida Hu, Casey Papovich, Taylor A. Hutchison +6
We present deep, hr, JWST NIRSpec G140M and G395M observations of a previously known galaxy C3PO-8447 at . Our new NIRSpec data from the Carbon-3 plus Oxygen (C3PO…
Skyfire: A Spectroscopic Census of Little Red Dots and Broad-Line AGN in the CEERS Field
Dale D. Kocevski, Anthony J. Taylor, Masafusa Onoue +24
We present the Skyfire program, a 21-hour Cycle 3 JWST/NIRSpec survey with the G395M medium-resolution grating covering five pointings in the Extended Groth Strip. The survey is de…
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…
