Quiescent Galaxies at from CAPERS spectroscopy and their Number densities
Lu Shen, Weida Hu, Casey Papovich +28
Recent JWST observations have revealed an overabundance of quiescent galaxies at high redshift. Photometric methods, such as photometry-derived sSFRs, colors, and synthetic $…
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…
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…
An emerging baryon cycle in a galaxy 500 million years after the Big Bang
Shengzhe Wang, Xin Wang, Hang Zhou +17
The emergence of stellar feedback as a regulator of galaxy growth marks a fundamental transition in cosmic history. At early times, rapid gas accretion and collapse may induce inte…
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…
The quasi-star model for Little Red Dots: potential and challenges
Fabrizio Gentile, Mauro Giavalisco, Emanuele Daddi +25
(Abridged) Little Red Dots (LRDs) are a class of sources discovered by JWST observationally defined by a "V-shaped" rest-frame UV-Optical SED, a compact or unresolved morphology, a…
Using Ly Transmitted Spectrum to Probe IGM Transmission and Identify Ionized Structures in Cosmic Reionization
Weida Hu, Casey Papovich, Lu Shen +16
We present a study of intergalactic medium (IGM) transmission at using high-signal-to-noise JWST/NIRSpec prism spectroscopy of 143 galaxies at from the CAPE…
Extreme Emission Line Galaxies in CEERS Are Powered by Star Formation, not AGN
Kelcey Davis, Madisyn Brooks, Jonathan R. Trump +28
We present a spectroscopic study of photometrically identified extreme emission-line galaxies (EELGs) with observed-frame equivalent widths (EWs) >5000 A of either H alpha or H bet…
