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…
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…
