Efficient Ionizers with Low H+[OIII] Equivalent Widths: JADES Spectroscopy of a Peculiar High-z Population
Isaac H. Laseter, Michael V. Maseda, Charlotte Simmonds +15
Early JWST photometric studies discovered a population of UV faint () Lyman break galaxies with spectral energy distributions implying young ages ($…
A Glimpse of the New Redshift Frontier Through Abell S1063
Vasily Kokorev, Hakim Atek, John Chisholm +31
We report the discovery of two galaxy candidates at redshifts between in JWST observations from the GLIMPSE survey. These robust sources were identified using a combi…
A Little Red Dot at within a Large Galaxy Overdensity
Jan-Torge Schindler, Joseph F. Hennawi, Frederick B. Davies +11
The nature of "Little Red Dots" and their relation to other forms of accreting supermassive black holes remain an open question. Here we report the discovery of a Little Red Dot at…
The Burstiness of Star Formation at : A Huge Diversity in the Recent Star Formation Histories of Very UV-faint Galaxies
Ryan Endsley, John Chisholm, Daniel P. Stark +2
IRAC data have long implied that early () galaxies often have very high specific star formation rates (sSFR30 Gyr), but JWST data have shown that at leas…
A Quasar-Anchored Protocluster at z=6.6 in the ASPIRE Survey: I. Properties of [OIII] Emitters in a 10 Mpc Overdensity Structure
Jaclyn B. Champagne, Feige Wang, Haowen Zhang +25
ASPIRE (A SPectroscopic survey of bIased halos in the Reionization Era) is a quasar legacy survey primarily using \textit{JWST} to target a sample of 25 quasars with NIRCam s…
A negligible contribution of two luminous ~ 7.5 galaxies to the ionizing photon budget of reionization
S. Gazagnes, J. Chisholm, R. Endsley +12
We present indirect constraints on the absolute escape fraction of ionizing photons () of the system GN 42912 which comprises two luminous galaxies ($M_{\rm…
The case for super-Eddington accretion in JWST broad-line AGN during the first billion years
Erini Lambrides, Rebecca Larson, Kristen Garofali +23
A multitude of JWST studies reveal a surprising over-abundance of over-massive accreting super-massive black holes (SMBHs) -- leading to a deepening tension between theory and obse…
Silencing the Giant: Evidence of AGN Feedback and Quenching in a Little Red Dot at z = 4.13
Vasily Kokorev, John Chisholm, Ryan Endsley +8
The James Webb Space Telescope (JWST) has uncovered a ubiquitous population of dust-obscured compact sources at . Many of these objects exhibit signs of active galactic…
Deep rest-UV JWST/NIRSpec spectroscopy of early galaxies: the demographics of CIV and N-emitters in the reionization era
Michael W. Topping, Daniel P. Stark, Peter Senchyna +12
JWST has recently discovered a subset of reionization era galaxies with ionized gas that is metal poor in oxygen and carbon but heavily-enriched in nitrogen. This abundance pattern…
A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE): Broad-line AGN at revealed by JWST/NIRCam WFSS
Xiaojing Lin, Feige Wang, Xiaohui Fan +33
Low-luminosity AGNs with low-mass black holes (BHs) in the early universe are fundamental to understanding the BH growth and their co-evolution with the host galaxies. Utilizing JW…
High-Redshift Extragalactic Science with the Single Aperture Large Telescope for Universe Studies (SALTUS) Space Observatory
Justin Spilker, Rebecca C. Levy, Daniel Marrone +10
This paper presents an overview of the high-redshift extragalactic science case for the Single Aperture Large Telescope for Universe Studies (SALTUS) far-infrared NASA probe-class…
[Ne v] emission from a faint epoch of reionization-era galaxy: evidence for a narrow-line intermediate mass black hole
J. Chisholm, D. A. Berg, R. Endsley +16
Here we present high spectral resolution NIRSpec observations of GN42437, a low-mass (log(M), compact (pc), extreme starburst galaxy…
Primordial Rotating Disk Composed of 15 Dense Star-Forming Clumps at Cosmic Dawn
S. Fujimoto, M. Ouchi, K. Kohno +43
Early galaxy formation, initiated by the dark matter and gas assembly, evolves through frequent mergers and feedback processes into dynamically hot, chaotic structures. In contrast…
Extreme emission line galaxies detected in JADES JWST/NIRSpec I: inferred galaxy properties
Kit Boyett, Andrew J. Bunker, Emma Curtis-Lake +33
Extreme emission line galaxies (EELGs) exhibit large equivalent widths (EW) in their rest-optical emission lines ([OIII] or H rest-frame EW) which can be t…
Metal-poor star formation at with JWST: new insight into hard radiation fields and nitrogen enrichment on 20 pc scales
Michael W. Topping, Daniel P. Stark, Peter Senchyna +11
Nearly a decade ago, we began to see indications that reionization-era galaxies power hard radiation fields rarely seen at lower redshift. Most striking were detections of nebular…
