The star-forming and ionizing properties of dwarf z 6-9 galaxies in JADES: insights on bursty star formation and ionized bubble growth
Chevallard, Jacopo; Carniani, Stefano; Bunker, Andrew J. +37 more
Reionization is thought to be driven by faint star-forming galaxies, but characterizing this population has long remained very challenging. Here, we utilize deep nine-band JADES (JWST Advanced Deep Extragalactic Survey)/NIRCam (Near-Infrared Camera) imaging to study the star-forming and ionizing properties of 756 $z\sim 6-9$ galaxies, including hu…
The galaxy UV luminosity function at z ≃ 11 from a suite of public JWST ERS, ERO, and Cycle-1 programs
Cullen, F.; McLure, R. J.; Dunlop, J. S. +8 more
We present a new determination of the evolving galaxy ultraviolet (UV) luminosity function (LF) over the redshift range 9.5 < z < 12.5 based on a wide-area (>250 arcmin2) data set of JWST NIRCam near-infrared imaging assembled from 13 public JWST surveys. Our relatively large-area search allows us to uncover a sample of 61 robu…
JWST PRIMER: a new multifield determination of the evolving galaxy UV luminosity function at redshifts z ≃ 9 - 15

We present a new determination of the evolving galaxy ultraviolet (UV) luminosity function (LF) over the redshift range
Galaxy build-up in the first 1.5 Gyr of cosmic history: insights from the stellar mass function at z 4-9 from JWST NIRCam observations
Pérez-González, Pablo G.; Santini, Paola; Dickinson, Mark +28 more
Combining the public JWST/NIRCam imaging programs CEERS, PRIMER, and JADES, spanning a total area of $\sim 500\, {\rm arcmin}^2$, we obtain a sample of $\gt $30 000 galaxies at $z_{\rm phot}\sim 4\!-\!9$ that allows us to perform a complete, rest-optical-selected census of the galaxy population at $z\gt 3$. Comparing the stellar mass $M_*$ and the…
EPOCHS VI: the size and shape evolution of galaxies since z 8 with JWST Observations
Conselice, C. J.; Adams, N. J.; Li, Q. +8 more
We present the results of a size and structural analysis of 1395 galaxies at 0.5 ≤ z ≲ 8 with stellar masses log (M*/M⊙)> 9.5 within the James Webb Space Telescope Public CEERS field that overlaps with the Hubble Space Telescope Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey EGS observations. We use GALFIT …
The UV continuum slopes of early star-forming galaxies in JADES
Chevallard, Jacopo; Carniani, Stefano; Bunker, Andrew J. +22 more
The power-law slope of the rest-ultraviolet (UV) continuum (fλ ∝ λβ) is a key metric of early star-forming galaxies, providing one of our only windows into the stellar populations and physical conditions of z ≳ 10 galaxies. Expanding upon previous studies with limited sample sizes, we leverage deep imaging from the JWST Advan…
Extreme emission line galaxies detected in JADES JWST/NIRSpec - I. Inferred galaxy properties
Charlot, Stéphane; Chevallard, Jacopo; Maseda, Michael V. +33 more
Extreme emission line galaxies (EELGs) exhibit large equivalent widths (EW) in their rest-optical emission lines ([O III]
The ultraviolet continuum slopes of high-redshift galaxies: evidence for the emergence of dust-free stellar populations at z > 10
Bowler, R. A. A.; Cullen, F.; McLure, R. J. +11 more
We present an analysis of the ultraviolet (UV) continuum slopes (β) for a sample of 172 galaxy candidates at 8 < zphot < 16 selected from a combination of JWST NIRCam imaging and COSMOS/UltraVISTA ground-based near-infrared imaging. Focusing primarily on a new sample of 121 galaxies at ⟨z⟩ ≃ 11 selected from ≃ 320 arcmin2
Fundamental scaling relationships revealed in the optical light curves of tidal disruption events
Ingram, Adam; van Velzen, Sjoert; Hammerstein, Erica +4 more
We present fundamental scaling relationships between properties of the optical/UV light curves of tidal disruption events (TDEs) and the mass of the black hole that disrupted the star. We have uncovered these relations from the late-time emission of TDEs. Using a sample of 63 optically selected TDEs, the latest catalogue to date, we observed flatt…
Insight from JWST/Near Infrared Camera into galaxy overdensities around bright Lyman-alpha emitters during reionization: implications for ionized bubbles at z 9
Charlot, Stéphane; Chen, Zuyi; Stark, Daniel P. +4 more
Several studies have detected Lyman-alpha (Ly Α) from bright ($M_{\small UV}\lesssim -21.5$) galaxies during the early stages of reionization despite the significantly neutral intergalactic medium. To explain these detections, it has been suggested that z > 7 Ly Α emitters (LAEs) inhabit physical Mpc (pMpc)-scale ionized regions powered by over…
