A CRASH simulation of the contribution of binary stars to the epoch of reionization
Qing-Bo Ma, Silvia Fiaschi, Benedetta Ciardi +2
We use a set of 3D radiative transfer simulations to study the effect that a large fraction of binary stars in galaxies during the epoch of reionization has on the physical propert…
Investigating X-ray sources during the epoch of reionization with the 21 cm signal
Qing-Bo Ma, Benedetta Ciardi, Marius B. Eide +3
Heating of neutral gas by energetic sources is crucial for the prediction of the 21 cm signal during the epoch of reionization (EoR). To investigate differences induced on statisti…
Large scale simulations of H and He reionization and heating driven by stars and more energetic sources
Marius B. Eide, Benedetta Ciardi, Luca Graziani +3
We present simulations of cosmic reionization and reheating from to , investigating the role of stars (emitting soft UV-photons), nuclear black holes (BHs, with power-l…
Opening Reionization: Quantitative Morphology of the Epoch of Reionization and Its Connection to the Cosmic Density Field
Philipp Busch, Marius B. Eide, B. Ciardi +1
We introduce a versatile and spatially resolved morphological characterisation of binary fields, rooted in the opening transform of mathematical morphology. We subsequently apply i…
Probing the high-z IGM with the hyperfine transition of He
Shivan Khullar, Qingbo Ma, Philipp Busch +3
The hyperfine transition of He at 3.5cm has been thought as a probe of the high-z IGM since it offers a unique insight into the evolution of the helium component of the gas…
X-ray background and its correlation with the 21 cm signal
Q. Ma, B. Ciardi, M. B. Eide +1
We use high resolution hydrodynamical simulations to study the contribution to the X-ray background from high- energetic sources, such as X-ray binaries, accreting nuclear black…
The Epoch of IGM heating by early sources of X-rays
Marius Berge Eide, Luca Graziani, Benedetta Ciardi +3
Observations of the 21 cm line from neutral hydrogen indicate that an Epoch of Heating (EoH) might have preceded the later Epoch of Reionization (EoR). Here we study the effects on…
The Concerted Impact of Galaxies and QSOs on the Ionization and Thermal State of the Intergalactic Medium
Koki Kakiichi, Luca Graziani, Benedetta Ciardi +4
We present a detailed analysis of the ionization and thermal structure of the intergalactic medium (IGM) around a high-redshift QSO using a large suite of cosmological, multi-frequ…
