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…
Observing the redshifted 21 cm signal around a bright QSO at
Qing-Bo Ma, Benedetta Ciardi, Koki Kakiichi +3
We use hydrodynamics and radiative transfer simulations to study the 21~cm signal around a bright QSO at . Due to its powerful UV and X-ray radiation, the QSO quickly in…
The Tessellation-Level-Tree: characterising the nested hierarchy of density peaks and their spatial distribution in cosmological N-body simulations
Philipp Busch, Simon D. M. White
We use the Millennium and Millennium-II simulations to illustrate the Tessellation-Level-Tree (TLT), a hierarchical tree structure linking density peaks in a field constructed by v…
The globular cluster system of the Auriga simulations
Timo L. R. Halbesma, Robert J. J. Grand, Facundo A. Gómez +5
We investigate whether the galaxy and star formation model used for the Auriga simulations can produce a realistic globular cluster (GC) population. We compare statistics of GC can…
