The Rise of Faint, Red AGN at : A Sample of Little Red Dots in the JWST Extragalactic Legacy Fields
Dale D. Kocevski, Steven L. Finkelstein, Guillermo Barro +54
We present a sample of 341 "little red dots" (LRDs) spanning the redshift range using data from the CEERS, PRIMER, JADES, UNCOVER and NGDEEP surveys. Unlike past use of…
Introducing a Real-time Interactive GUI Tool for Visualization of Galaxy Spectra
Ho-Hin Leung, Vivienne Wild, Adam Carnall +1
To aid the understanding of the non-linear relationship between galaxy properties and predicted spectral energy distributions (SED), we present a new interactive graphical user int…
The star formation histories of z~1 post-starburst galaxies
Vivienne Wild, Laith Taj Aldeen, Adam Carnall +11
We present the star formation histories of 39 galaxies with high quality rest-frame optical spectra at 0.5<z<1.3 selected to have strong Balmer absorption lines and/or Balmer break…
A census of star formation histories of massive galaxies at 0.6 < z < 1 from spectro-photometric modeling using Bagpipes and Prospector
Yasha Kaushal, Angelos Nersesian, Rachel Bezanson +12
We present individual star-formation histories of massive galaxies (log() > 10.5) from the Large Early Galaxy Astrophysics Census (LEGA-C) spectr…
The quenching time and timescale distribution of z~2 quiescent galaxies from precise colour distribution analysis
Vivienne Wild, Ho-Hin Leung, Adam Carnall +1
Understanding when and how galaxies quench their star formation is crucial for understanding the dominant physical processes at play. The spectral energy distribution (SED) of gala…
Confirmation and refutation of very luminous galaxies in the early universe
Pablo Arrabal Haro, Mark Dickinson, Steven L. Finkelstein +34
During the first 500 million years of cosmic history, the first stars and galaxies formed, seeding the Universe with heavy elements and eventually reionizing the intergalactic medi…
Uncovering the physical origin of the prominent Lyman- emission and absorption in GS9422 at
Chamilla Terp, Kasper E. Heintz, Darach Watson +5
We present a comprehensive spectro-photometric analysis of the galaxy GS9422 from the JADES GTO survey located at , anomalously showing a simultaneous strong Ly emissi…
RELICS: Properties of z>5.5 Galaxies Inferred from Spitzer and Hubble Imaging Including A Candidate z~6.8 Strong [OIII] Emitter
Victoria Strait, Marusa Bradac, Dan Coe +26
We present constraints on the physical properties (including stellar mass, age, and star formation rate) of 207 galaxy candidates from the Reionization Lens…
Chemical evolution of local post-starburst galaxies: Implications for the mass-metallicity relation
Ho-Hin Leung, Vivienne Wild, Michail Papathomas +5
We use the stellar fossil record to constrain the stellar metallicity evolution and star-formation histories of the post-starburst (PSB) regions within 45 local post-starburst gala…
High-Redshift Galaxy Candidates at as Revealed by JWST Observations of WHL0137-08
Larry D. Bradley, Dan Coe, Gabriel Brammer +25
We report the discovery of four galaxy candidates observed 450 - 600 Myr after the Big Bang with photometric redshifts between z ~ 8.3 - 10.2 measured using the JWST NIRCam imaging…
CAPERS-LRD-z9: A Gas Enshrouded Little Red Dot Hosting a Broad-line AGN at z=9.288
Anthony J. Taylor, Vasily Kokorev, Dale D. Kocevski +49
We present CAPERS-LRD-z9, a little red dot (LRD) which we confirm to be a broad-line AGN (BLAGN). First identified as a high-redshift LRD candidate from PRIMER NIRCam pho…
Remarkably Compact Quiescent Candidates at in JWST-CEERS
Lillian Wright, Katherine E. Whitaker, John R. Weaver +9
In this letter, we measure the rest-frame optical and near-infrared sizes of ten quiescent candidates at , first reported by Carnall et al. (2023a). We use James Webb Space…
