Cosmological radiative transfer codes comparison project – I. The static density field tests

- I. Iliev, B. Ciardi,
+24 authors Rikkyo U. Lanl - Physics
- 8 March 2006

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 time… Expand

Simulating Cosmic Reionization at Large Scales I: the Geometry of Reionization

- I. Iliev, G. Mellema,
+7 authors U. T. Austin - Physics
- 7 December 2005

We present the first large-scale radiative transfer simulat ions of cosmic reionization, in a simulation volume of (100 h 1 Mpc) 3 . This is more than a 2 orders of magnitude improvement over… Expand

The halo mass function through the cosmic ages

In this paper we investigate how the halo mass function evolves with redshift, based on a suite of very large (with N_p = 3072^3 - 6000^3 particles) cosmological N-body simulations. Our halo… Expand

Self-regulated reionization

- I. Iliev, G. Mellema, P. Shapiro, Ue-Li Pen Cita, S. University, U. Texas
- Physics
- 22 July 2006

Recently, we have presented the first, truly large-scale radiative transfer simulations of inhomogeneous cosmic reionization which resolve all the possible halo sources down to the dwarf galaxy mass… Expand

C2-ray: A new method for photon-conserving transport of ionizing radiation

- G. Mellema, I. Iliev,
+10 authors Austin - Physics

Upper limits on the 21 cm Epoch of Reionization power spectrum from one night with LOFAR

- A. H. Patil, S. Yatawatta,
+25 authors S. Wijnholds - Physics
- 28 February 2017

We present the first limits on the Epoch of Reionization 21 cm H I power spectra, in the redshift range z = 7.9–10.6, using the Low-Frequency Array (LOFAR) High-Band Antenna (HBA). In total, 13.0 hr… Expand

On the use of Lyα emitters as probes of reionization

- H. Jensen, P. Laursen, G. Mellema, I. Iliev, J. Sommer-Larsen, P. Shapiro
- Physics
- 18 June 2012

We use numerical simulations to study the effects of the patchiness of a partly reionized intergalactic medium (IGM) on the observability of Lyα emitters (LAEs) at high redshifts (z ≳ 6). We present… Expand

Simulating cosmic reionization at large scales – II. The 21-cm emission features and statistical signals

- G. Mellema, I. Iliev,
+5 authors U. Austin - Physics
- 19 March 2006

We present detailed predictions for the redshifted 21-cm signal from the epoch of reionization. These predictions are obtained from radiative transfer calculations on the results of large-scale (100… Expand

The Inhomogeneous Background Of H2-Dissociating Radiation During Cosmic Reionization

- K. Ahn, P. Shapiro, I. Iliev, G. Mellema, U. Pen
- Physics
- 6 July 2008

The first, self-consistent calculations are presented of the cosmological, H2-dissociating UV background produced during the epoch of reionization by the sources of reionization. Large-scale… Expand

Topology and Sizes of HII Regions during Cosmic Reionization

- Martina M. Friedrich, G. Mellema, M. Alvarez, P. Shapiro, I. Iliev
- Physics
- 10 June 2010

We use the results of large-scale simulations of reionization to explore methods for characterizing the topology and sizes of HII regions during reionization. We use four independent methods for… Expand
