21cmEMUv3: a hybrid diffusion-LSTM emulator of 21cmFAST summary observables
Daniela Breitman, Andrei Mesinger, Steven G. Murray +2
We are witnessing a surge in observations of the cosmic dawn (CD) and epoch of reionisation (EoR), driving an increasing demand for fast and robust theoretical interpretation frame…
Characterizing Lyman alpha emission from high-redshift galaxies
Samuel Gagnon-Hartman, Andrei Mesinger, Ivan NikoliÄ +2
The Lyman (Ly) line from high-redshift galaxies is a powerful probe of the Epoch of Reionization (EoR). Neutral hydrogen in the intergalactic medium (IGM) can significantl…
Mapping reionization bubbles in the JWST era II: inferring the position and characteristic size of individual bubbles
Ivan NikoliÄ, Andrei Mesinger, Charlotte A. Mason +5
The James Webb Space Telescope (JWST) is discovering an increasing number of galaxies well into the early stages of the Epoch of Reionization (EoR). Many of these galaxies are clus…
Inferring reionization and galaxy properties from the patchy kinetic Sunyaev-Zel'dovich signal
Ivan NikoliÄ, Andrei Mesinger, Yuxiang Qin +1
The patchy kinetic Sunyaev-Zel'dovich (kSZ) signal is an integral probe of the timing and morphology of the epoch of reionization (EoR). Recent observations have claimed a low sign…
Mapping reionization bubbles in the JWST era I: empirical edge detection with Lyman alpha emission from galaxies
Ting-Yi Lu, Charlotte A. Mason, Andrei Mesinger +7
Ionized bubble sizes during reionization trace physical properties of the first galaxies. JWST's ability to spectroscopically confirm and measure Lyman-alpha (Ly) emission in s…
The importance of stochasticity in determining galaxy emissivities and UV LFs during cosmic dawn and reionization
Ivan NikoliÄ, Andrei Mesinger, James E. Davies +1
The stochastic nature of star formation and photon propagation in high-redshift galaxies can result in sizable galaxy-to-galaxy scatter in their properties. Ignoring this scatter b…
