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…

A Steep Decline in the Galaxy Space Density Beyond Redshift 9 in the CANUCS UV Luminosity Function

Chris J. Willott, Guillaume Desprez, Yoshihisa Asada +15

We present a new sample of 158 galaxies at redshift selected from deep \jwst\ NIRCam imaging of five widely-separated sightlines in the CANUCS survey. Two-thirds of the poi…

FRESCO: An extended, massive, rapidly rotating galaxy at z=5.3

Erica J. Nelson, Gabriel Brammer, Clara Gimenez-Arteaga +43

With the remarkable sensitivity and resolution of JWST in the infrared, measuring rest-optical kinematics of galaxies at has become possible for the first time. This study pi…

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…

CDM not dead yet: massive high-z Balmer break galaxies are less common than previously reported

Guillaume Desprez, Nicholas S. Martis, Yoshihisa Asada +15

Early JWST observations that targeted so-called double-break sources (attributed to Lyman and Balmer breaks at ), reported a previously unknown population of very massive, evo…

Bursty star formation and galaxy-galaxy interactions in low-mass galaxies 1 Gyr after the Big Bang

Yoshihisa Asada, Marcin Sawicki, Roberto Abraham +14

We use CANUCS JWST/NIRCam imaging of galaxies behind the gravitationally-lensing cluster MACS J0417.5-1154 to investigate star formation burstiness in low-mass ($M_\star\sim10^8\ M…
