The Clustering of Galaxies in the Completed SDSS-III Baryon Oscillation Spectroscopic Survey: Cosmic Flows and Cosmic Web from Luminous Red Galaxies
Metin Ata, Francisco-Shu Kitaura, Chia-Hsun Chuang +31
We present a Bayesian phase-space reconstruction of the cosmic large-scale matter density and velocity fields from the SDSS-III Baryon Oscillations Spectroscopic Survey Data Releas…
Exploring 21cm - Lyman Alpha emitter synergies for SKA
Anne Hutter, Pratika Dayal, Volker Müller +1
We study the signatures of reionization and ionizing properties of the early galaxies in the cross-correlations between the 21cm emission from the spin-flip transition of neutral h…
Bayesian inference of cosmic density fields from non-linear, scale-dependent, and stochastic biased tracers
Metin Ata, Francisco-Shu Kitaura, Volker Müller
We present a Bayesian reconstruction algorithm to generate unbiased samples of the underlying dark matter field from halo catalogues. Our new contribution consists of implementing…
Non-Gaussian inference from non-linear and non-Poisson biased distributed data
Metin Ata, Francisco-Shu Kitaura, Volker Müller
We study the statistical inference of the cosmological dark matter density field from non-Gaussian, non-linear and non-Poisson biased distributed tracers. We have implemented a Bay…
The cosmic web of the Local Universe: cosmic variance, matter content and its relation to galaxy morphology
Sebastian E. Nuza, Francisco-Shu Kitaura, Steffen Hess +2
We present, for the first time, a Local Universe (LU) characterization using high precision constrained -body simulations based on self-consistent phase-space reconstructions of…
The visibility of Lyman Alpha Emitters: constraining reionization, ionizing photons and dust
A. Hutter, P. Dayal, A. M. Partl +1
We build a physical model for high-redshift Lyman Alpha emitters (LAEs) by coupling state of the art cosmological simulations (GADGET-2) with a dust model and a radiative transfer…
Simulating extremely metal-poor gas and DLA metal content at redshift z=7
Umberto Maio, Benedetta Ciardi, Volker Mueller
We present the first theoretical study of metals in damped Ly-alpha (DLA) systems at redshift z=7. The features of cold, primordial gas are studied by means of N-body, hydro, chemi…
The evolution of HI and CIV quasar absorption line systems at 1.9 < z < 3.2
Tae-Sun Kim, Adrian M. Partl, Robert F. Carswell +1
We have investigated the distribution and evolution of ~3100 intergalactic HI absorbers with HI column densities log N(HI) = [12.75, 17.0] at 1.9 < z < 3.2, using 18 high resolutio…
Measuring the Cosmic Web
Volker Mueller, Kai Hoffmann, Sebastian E. Nuza
A quantitative study of the clustering properties of the cosmic web as a function of absolute magnitude and colour is presented using the SDSS Data Release 7 galaxy survey. Mark co…
Large scale environmental bias of the QSO line of sight proximity effect
Adrian M. Partl, Volker Müller, Gustavo Yepes +1
We analyse the proximity zone of the intergalactic matter around high-redshift quasars in a cosmological environment. In a box of 64 h-1 Mpc base length we employ dark matter only…
Enabling parallel computing in CRASH
Adrian M. Partl, Antonella Maselli, Benedetta Ciardi +2
We present the new parallel version (pCRASH2) of the cosmological radiative transfer code CRASH2 for distributed memory supercomputing facilities. The code is based on a static dom…
Wavelet analysis of the formation of the cosmic web
J. Einasto, G. Hütsi, E. Saar +6
According to the modern cosmological paradigm galaxies and galaxy systems form from tiny density perturbations generated during the very early phase of the evolution of the Univers…
Cosmological radiative transfer for the line-of-sight proximity effect
Adrian M. Partl, Aldo Dall'Aglio, Volker Müller +1
We study the proximity effect in the Ly-a forest around high redshift quasars as a function of redshift and environment employing a set of 3D radiative transfer simulations. The an…
