Cosmological radiative transfer codes comparison project – I. The static density field tests
Radiative transfer (RT) simulations are now at the forefront of numerical astrophysics. They are becoming crucial for an increasing number of astrophysical and cosmological problems; at the same timeExpand
The building blocks of the full body ownership illusion
It is found that the illusion of ownership can be generated when the virtual body has a realistic skin tone and spatially substitutes the real body seen from a first person perspective, and the processing of incongruent perceptual cues can be modulated by the level of the illusion. Expand
Over my fake body: body ownership illusions for studying the multisensory basis of own-body perception
A conceptualization based on Bayesian causal inference is proposed for addressing how the authors' nervous system could infer whether an object belongs to their own body, using multisensory, sensorimotor, and semantic information, and how this can account for several experimental findings. Expand
CRASH: A radiative transfer scheme
We present a largely improved version of crash, a 3D radiative transfer code that treats the effects of ionizing radiation propagating through a given inhomogeneous H/He cosmological density field onExpand
The visibility of Lyman α emitters during reionization
We present the first Lyman α emitter (LAE) study that combines: (i) cosmological smoothed particle hydrodynamic (SPH) simulations run using GADGET-2, (ii) radiative transfer simulations (CRASH) andExpand
Sliding perspectives: dissociating ownership from self-location during full body illusions in virtual reality
It is argued that changes in the perceived self-location are associated to the dynamical representation of peripersonal space encoded by visuotactile neurons, and results speak in favor of visuo-proprioceptive neuronal populations being a driving trigger in full body ownership illusions. Expand
Prospects for detecting the 21 cm forest from the diffuse intergalactic medium with LOFAR
We discuss the feasibility of the detection of the 21 cm forest in the diffuse intergalactic medium (IGM) with the radio telescope LOFAR. The optical depth to the 21 cm line has been derived usingExpand
The Lyα forest around high-redshift galaxies
Motivated by the relative lack of neutral hydrogen around Lyman-break galaxies deduced from recent observations, we investigate the properties of the Lya forest around high-redshift galaxies. TheExpand
Radiative transfer effects on the Lyα forest
Strong observational evidence for a fluctuating ultraviolet background (UVB) has been accumulating through a number of studies of the H I and He II Lyα forest as well as accurate intergalactic mediumExpand
On the size of H II regions around high-redshift quasars
We investigate the possibility of constraining the ionization state of the intergalactic medium (IGM) close to the end of reionization (z ≈ 6) by measuring the size of H II regions in high-z quasarExpand
