A JWST Paschen-alpha Calibration of the Radio Luminosity-Star Formation Rate Relation at z~1.3
Nick Seymour, Catherine Hale, Imogen Whittam +17
As radio emission from normal galaxies is a dust-free tracer of star formation, tracing the star formation history of the Universe is a key goal of the SKA and ngVLA. In order to i…
Not all protoclusters host evolved galaxies: Evidence for reduced environmental effects in a lower halo mass protocluster at
Callum Witten, Pascal A. Oesch, Jake S. Bennett +5
The progenitors of present-day galaxy clusters offer crucial insight into how galaxies and large-scale structure co-evolve in the early Universe. We present JWST/NIRCam grism spect…
The slope and scatter of the star forming main sequence at z~5 : reconciling observations with simulations
Claudia Di Cesare, Jorryt Matthee, Rohan P. Naidu +17
Galaxies exhibit a tight correlation between their star-formation rate and stellar mass over a wide redshift range known as the star-forming main sequence (SFMS). With JWST, we can…
Lyman-alpha emission at the end of reionization: line strengths and profiles from MMT and JWST observations at z~5-6
Gonzalo Prieto-Lyon, Charlotte A. Mason, Victoria Strait +8
With JWST, it is now possible to use Lyman-Alpha (Ly) emission from galaxies beyond z>8 to trace neutral hydrogen in the intergalactic medium (IGM) as the Universe became reioni…
JWST+ALMA reveal the build up of stellar mass in the cores of dusty star-forming galaxies at Cosmic Noon
Sarah Bodansky, Katherine E. Whitaker, Ayesha Abdullah +14
Dusty star-forming galaxies have long been suspected to serve as the missing evolutionary bridge between the star-forming and quiescent phases of massive galaxy evolution. With the…
Stochastic star formation activity of galaxies within the first billion years probed by JWST
C. Carvajal-Bohorquez, L. Ciesla, N. Laporte +8
In this work, we aim at characterizing the burstiness level of high-redshift galaxy SFHs and its evolution. We implement a stochastic SFH in CIGALE using PSD, to estimate the burst…
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 "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)…
No [CII] or dust detection in two Little Red Dots at z > 7
Mengyuan Xiao, Pascal A. Oesch, Longji Bing +30
Little Red Dots (LRDs) are compact, point-like sources characterized by their red color and broad Balmer lines, which have been debated to be either dominated by active galactic nu…
An Hα view of galaxy build-up in the first 2 Gyr: luminosity functions at z~4-6.5 from NIRCam/grism spectroscopy
Alba Covelo-Paz, Emma Giovinazzo, Pascal A. Oesch +22
The Hα nebular emission line is an optimal tracer for recent star formation in galaxies. With the advent of JWST, this line has recently become observable at z>3 for the first time…
A massive, neutral gas reservoir permeating a galaxy proto-cluster after the reionization era
Kasper E. Heintz, Jake S. Bennett, Pascal A. Oesch +21
Galaxy clusters are the most massive, gravitationally-bound structures in the Universe, emerging through hierarchical structure formation of large-scale dark matter and baryon over…
JWST FRESCO: a comprehensive census of H+[OIII] emitters at 6.8<z<9.0 in the GOODS fields
R. A. Meyer, P. A. Oesch, E. Giovinazzo +27
We present the census of H+[OIII] 4960,5008 Åemitters at 6.8<z<9.0 from the JWST FRESCO survey over 124 arcmin in the GOODS-North and GOODS-South fields. Our unbiased spectr…
A First Look at Spatially Resolved Star Formation at with JWST FRESCO NIRCam Slitless Spectroscopy
Jasleen Matharu, Erica J. Nelson, Gabriel Brammer +19
We present the first results on the spatial distribution of star formation in 454 star-forming galaxies at using H-Alpha emission-line maps and F444W imaging tracing th…
FRESCO: The Paschen- Star Forming Sequence at Cosmic Noon
Chloe Neufeld, Pieter van Dokkum, Yasmeen Asali +17
We present results from the JWST First Reionization Epoch Spectroscopically Complete Observations survey (FRESCO) on the star forming sequence of galaxies at , around th…
New red giants in NGC 6791 and NGC 6819 using Kepler superstamps
A. Covelo-Paz, N. Themeßl, F. Espinoza-Rojas +1
Context. Stars that are members of stellar clusters are assumed to be formed at the same time and place from material with the same initial chemical composition. These additional c…
