Stellar Morphology of Optically Dark or Faint Galaxies at with JWST
Arpita Ganguly, Mengyuan Xiao, Pascal A. Oesch +11
JWST offers an unprecedented view of optically dark or faint galaxies (OFGs), previously missed by HST. They are likely massive, heavily dust-obscured star-forming galaxies (SFGs)…
The Mass-Metallicity Relation and its Observational Effects at z~3-6
Zach Lewis, Michael V. Maseda, Anna de Graaff +21
The correlation between galaxy stellar mass and gas-phase metallicity, known as the mass-metallicity relation (MZR), gives key insights into the processes that govern galaxy evolut…
Exploring Cosmic Dawn with PANORAMIC II: Cosmic Variance and Galaxy Clustering at
Andrea Weibel, Christian Kragh Jespersen, Pascal A. Oesch +10
Observational campaigns with JWST have revealed a higher-than-expected abundance of UV-bright galaxies at , with various proposed theoretical explanations. A powerful c…
JWST's GLIMPSE: an overview of the deepest probe of early galaxy formation and cosmic reionization
Hakim Atek, John Chisholm, Vasily Kokorev +44
We present an overview of the JWST GLIMPSE program, highlighting its survey design, primary science goals, gravitational lensing models, and first results. GLIMPSE provides ultra-d…
The stellar mass function of quiescent and star-forming galaxies and its dependence on morphology in COSMOS-Web
Marko Shuntov, Olivier Ilbert, Claudia del P. Lagos +33
We study the stellar mass function (SMF) of quiescent and star-forming galaxies and its dependence on morphology in 10 redshift bins at using the COSMOS2025 catalog bui…
Little Red Dots host Black Hole Stars: A unified family of gas-reddened AGN revealed by JWST/NIRSpec spectroscopy
Anna de Graaff, Raphael E. Hviding, Rohan P. Naidu +34
We use the DAWN JWST Archive to construct and characterise a sample of 146 little red dots (LRDs) across 2.0<z<9.3, selecting all sources with v-shaped UV-optical continua from NIR…
JWST Spectroscopic Insights Into the Diversity of Galaxies in the First 500 Myr: Short-Lived Snapshots Along a Common Evolutionary Pathway
Guido Roberts-Borsani, Pascal Oesch, Richard Ellis +21
We investigate the nature and spectroscopic diversity of early galaxies from a sample of 41 sources at z>10 with JWST/NIRSpec prism observations. We compare the properties of stron…
Exploring Cosmic Dawn with PANORAMIC I: The Bright End of the UVLF at
Andrea Weibel, Pascal A. Oesch, Christina C. Williams +14
In its first two years of operation, the James Webb Space Telescope has enabled the discovery of a surprising number of UV-bright galaxies at . Their number density is…
Breaking Through the Cosmic Fog: JWST/NIRSpec Constraints on Ionizing Photon Escape in Reionization-Era Galaxies
Emma Giovinazzo, Pascal A. Oesch, Andrea Weibel +15
The escape fraction of Lyman continuum photons (fesc(LyC)) is the last key unknown in our understanding of cosmic reionization. Directly estimating the escape fraction (fesc) of io…
A systematic search for dormant galaxies at z~5-7 from the JWST NIRSpec archive
Alba Covelo-Paz, Corentin Meuwly, Pascal A. Oesch +6
JWST has revealed a population of ``dormant'' galaxies at that have recently halted their star formation and are characterized by weak emission lines and significant Balmer b…
A Cosmic Miracle: A Remarkably Luminous Galaxy at Confirmed with JWST
Rohan P. Naidu, Pascal A. Oesch, Gabriel Brammer +43
JWST has revealed a stunning population of bright galaxies at surprisingly early epochs, , where few such sources were expected. Here we present the most distant example of t…
A "Black Hole Star" Reveals the Remarkable Gas-Enshrouded Hearts of the Little Red Dots
Rohan P. Naidu, Jorryt Matthee, Harley Katz +48
The physical processes that led to the formation of billion solar mass black holes within the first 700 million years of cosmic time remain a puzzle. Several theoretical scenarios…
Constraints on the early Universe star formation efficiency from galaxy clustering and halo modeling of H and [O III] emitters
Marko Shuntov, Pascal A. Oesch, Sune Toft +13
We develop a theoretical framework to provide observational constraints on the early Universe galaxy-halo connection by combining measurements of the UV luminosity function (UVLF)…
A remarkable Ruby: Absorption in dense gas, rather than evolved stars, drives the extreme Balmer break of a Little Red Dot at
Anna de Graaff, Hans-Walter Rix, Rohan P. Naidu +25
The origin of the rest-optical emission of compact, red, high-redshift sources known as `little red dots' (LRDs) poses a major puzzle. If interpreted as starlight, it would imply t…
Gas outflows in two recently quenched galaxies at z = 4 and 7
F. Valentino, K. E. Heintz, G. Brammer +33
Outflows are a key element in the baryon cycle of galaxies, and their properties provide a fundamental test for our models of how star formation quenches in galaxies. Here we repor…
GLIMPSE: An ultra-faint 10 Pop III Galaxy Candidate and First Constraints on the Pop III UV Luminosity Function at
Seiji Fujimoto, Rohan P. Naidu, John Chisholm +32
Detecting the first generation of stars, Population III (PopIII), has been a long-standing goal in astrophysics, yet they remain elusive even in the JWST era. Here we present a nov…
