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 $…
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…
Massive Galaxies Form Early and Gray: Stellar Assembly and Dust Attenuation at from CAPERS
Katherine Chworowsky, Steven L. Finkelstein, Anthony J. Taylor +27
The stellar mass assembly of massive galaxies in the first few billion years of cosmic history remains a central challenge in galaxy formation. Galaxies with $M_\star \gtrsim 10^{1…
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…
NGDEEP: A New Non-Parametric Measure of Local Star-Formation and Attenuation at Cosmic Noon
Grace M. Forrey, Raymond C. Simons, Jonathan R. Trump +6
We introduce a new non-parametric technique to quantify the spatially-resolved relationship between the local star-formation rate (SFR) and dust attenuation. We then apply it to 14…
A first look at a complete view of spatially resolved star formation at 1<z<1.8 with JWST NGDEEP+FRESCO slitless spectroscopy
Jasleen Matharu, Lu Shen, Irene Shivaei +15
[abridged] The previously inaccessible star formation tracer Pa can now be spatially resolved by JWST NIRCam slitless spectroscopy in distant galaxies up to cosmic noon. In the…
Galaxies in the Epoch of Reionization Are All Bark and No Bite -- Plenty of Ionizing Photons, Low Escape Fractions
Casey Papovich, Justin W. Cole, Weida Hu +27
Early results from JWST suggest that epoch-of-reionization (EoR) galaxies produce copious ionizing photons, which, if they escape efficiently, could cause reionization to occur too…
Extended Enriched Gas in a Multi-Galaxy Merger at Redshift 6.7
Weida Hu, Casey Papovich, Lu Shen +5
Recent JWST observations have uncovered high-redshift galaxies characterized by multiple star-forming clumps, many of which appear to be undergoing mergers. Such mergers, especiall…
NGDEEP: The Star Formation and Ionization Properties of Galaxies at
Lu Shen, Casey Papovich, Jasleen Matharu +23
We use JWST/NIRISS slitless spectroscopy from the Next Generation Deep Extragalactic Exploratory Public (NGDEEP) Survey to investigate the physical condition of star-forming galaxi…
Characterizing the Average Interstellar Medium Conditions of Galaxies at 5.6-9 with UV and Optical Nebular Lines
Weida Hu, Casey Papovich, Mark Dickinson +30
Ultraviolet (UV; rest-frame A) spectra provide a wealth of diagnostics to characterize fundamental galaxy properties, such as their chemical enrichment, the nature…
The Next Generation Deep Extragalactic Exploratory Public Near-Infrared Slitless Survey Epoch 1 (NGDEEP-NISS1): Extra-Galactic Star-formation and Active Galactic Nuclei at 0.5 < z < 3.6
Nor Pirzkal, Barry Rothberg, Casey Papovich +48
The Next Generation Deep Extragalactic Exploratory Public (NGDEEP) survey program was designed specifically to include Near Infrared Slitless Spectroscopic observations (NGDEEP-NIS…
CEERS: 7.7 m PAH Star Formation Rate Calibration with JWST MIRI
Kaila Ronayne, Casey Papovich, Guang Yang +33
We test the relationship between UV-derived star formation rates (SFRs) and the 7.7 m polycyclic aromatic hydrocarbon (PAH) luminosities from the integrated emission of galaxies…
NGDEEP Epoch 1: Spatially Resolved H Observations of Disk and Bulge Growth in Star-Forming Galaxies at 0.6-2.2 from JWST NIRISS Slitless Spectroscopy
Lu Shen, Casey Papovich, Jasleen Matharu +21
We study the H equivalent width, EW(H), maps of 19 galaxies at in the Hubble Ultra Deep Field (HUDF) derived from NIRISS slitless spectroscopy as part of the…
