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…
GLIMPSED: Direct evidence for a fast active galactic nucleus-driven outflow from a z=6.64 little red dot host galaxy
Damien Korber, Rui Marques-Chaves, Daniel Schaerer +15
We report the discovery of GLIMPSED-329380, a z=6.64 galaxy behind Abell S1063, which shows signs of an extreme ionised outflow driven by an active galactic nucleus (AGN). The deep…
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,…
GLIMPSE-DDT spectroscopic properties of faint-end galaxies at : Towards first metal enrichment, dust production, and ionizing photon production
Yoshihisa Asada, Seiji Fujimoto, John Chisholm +16
Ultra-faint galaxies at high- are fundamental elements of the early galaxy assembly, and spectroscopic characterization of this population is essential to understand the earlies…
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…
GLIMPSE-D: Metallicity Decline in Faint Galaxies: Implications for [O III]+Hb Luminosity Function and Reionisation Budget
Damien Korber, Daniel Schaerer, Rui Marques-Chaves +13
We report the measurement of the R3=[O III]5008/Hb ratios for 54 galaxies in the GLIMPSE-D survey. Thanks to gravitational lensing, our sample includes galaxies with -20 < Muv < -1…
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…
Tracing The Start and End of Cosmic Reionization -- Exploring The Role of Ionizing Sources as drivers
Arghyadeep Basu
This thesis investigates the Epoch of Cosmic Reionization (EoR), a key period in the early Universe when the first luminous sources formed and their radiation transformed the inter…
Probing Helium Reionization Through the Hyperfine Transition Line
Arghyadeep Basu, Benedetta Ciardi, Enrico Garaldi
We investigate the hyperfine transition of as a promising probe of the IGM during the final stages of helium reionization. Utilising the most recent helium re…
Influence of the Spectral Energy Distribution of Reionization-Era Sources on the Lyman- Forest
Arghyadeep Basu, Benedetta Ciardi, James S. Bolton +2
Interpreting Lyman- forest properties during the epoch of reionization requires assumptions about the spectral energy distribution (SED) of ionizing sources. These are often sim…
Variability of the UV luminosity function with SPICE
Arghyadeep Basu, Aniket Bhagwat, Benedetta Ciardi +1
We investigate the variability of the UV luminosity function (UVLF) at using the SPICE suite of cosmological, radiation-hydrodynamic simulations, which include three distin…
Helium Reionization from Empirical Quasar Luminosity Functions before and after JWST
Arghyadeep Basu, Enrico Garaldi, Benedetta Ciardi
Recently, models of the quasar luminosity function (QLF) rooted on large observational compilations have been produced that, unlike their predecessors, feature a smooth evolution w…
