Simulations of Dust Content and Attenuation in Galaxies
Dhruv T. Zimmerman, Jed McKinney, Desika Narayanan +10
Correctly modeling the dust attenuation law in galaxies is essential to properly inferring their growth and physical properties. With the rapid discovery of galaxies by JWST…
Population III Host Candidates at : Strong He II and Absent UV Metal Lines in HETDEX Ly Emitters
Mahan Mirza Khanlari, Dustin Davis, Karl Gebhardt +15
Population III (Pop III) stars are expected to produce extremely hard ionizing spectra, yet direct evidence for their signature--strong narrow He II emission with wea…
JWST Reveals a Candidate Supermassive Black Hole Binary at z=4.3 in the Brightest Sub-millimeter Galaxy in COSMOS-Web
Jed McKinney, Ansh Gupta, Julian B. Munoz +13
We present JWST/NIRSpec PRISM and G395M grating spectroscopy for AzTEC-1, a massive sub-mm bright galaxy at in the COSMOS extragalactic field. The PRISM spectrum reveals s…
How can we finally see the first light? Status and perspective in the search for Population III stars
Alessandra Venditti, Daniel Schaerer, Erik Zackrisson +26
Finding the first (Population III or Pop III) stars is one of the fundamental quests of astronomy, aiming to deliver the missing link in how stars form at early cosmic times. Yet t…
When galaxies burst: enhanced shot-noise for line-intensity mapping in the JWST era
Ely D. Kovetz, Hovav Lazare, Sarah Libanore +2
Recent JWST observations indicate that star formation at is more stochastic than previously assumed, with rms log-SFR scatter dex at $M_h\!\sim\!10^{11}M…
A Glimpse of the Low-Mass End of the Direct Mass-Metallicity Relation at
Tiger Yu-Yang Hsiao, John Chisholm, Danielle A. Berg +22
The competition between metal synthesis and feedback from massive stars establishes the mass-metallicity relation (MZR) at low-redshifts. Examining this relation at higher redshift…
A GLIMPSE of the 99%: a census of the faintest galaxies during the epoch of reionization and its implications for galaxy formation models
Hakim Atek, Iryna Chemerynska, Lukas J. Furtak +19
We present a comprehensive study of the galaxy UV luminosity function (UVLF) at leveraging deep JWST observations from the GLIMPSE survey. Thanks to gravitational lensing,…
Catching the Nebular Needle in a Polluted Haystack: Line-emission Signatures from Population III-forming Pockets around Massive Galaxies at the End of Reionization
Alessandra Venditti, Luca Graziani, Raffaella Schneider +10
Finding the first generation of (Population III or Pop III) stars is one of the most ambitious and exciting challenges of astrophysics. JWST opened concrete prospects for their det…
Little Red Dots as Globular Clusters in Formation
John Chisholm, Danielle A. Berg, Michael Boylan-Kolchin +7
Little Red Dots (LRDs), among the most enigmatic high-redshift discoveries by JWST, are commonly believed to be powered by accreting supermassive black holes. Here, we explore the…
A GLIMPSE into the UV Continuum Slopes of the Faintest Galaxies in the Epoch of Reionization
Michelle C. Jecmen, John Chisholm, Hakim Atek +23
As observations have yet to constrain the ionizing properties of the faintest (M > -16) galaxies, their contribution to cosmic reionization remains unclear. The rest-fra…
Semi-analytical approach to Ly multiple-scattering in 21-cm signal simulations
Jordan Flitter, Julian B. Muñoz, Andrei Mesinger
A crucial physical quantity in determining the 21-cm signal during cosmic dawn is the inhomogeneous background of Ly photons originating from the first galaxies. As these photon…
Relatively Fast and Reasonably Furious: Evidence for Increased Burstiness in Smaller Halos at Cosmic Dawn
Julian B. Muñoz, John Chisholm, Guochao Sun +7
We introduce an effective framework to model star-formation burstiness and use it to jointly fit galaxy UV luminosity functions (UVLFs), clustering, and H/UV ratios, providing t…
