Mapping the SKA Simulated Skies with the S3-Tools
F. Levrier, R. J. Wilman, D. Obreschkow +3
The S3-Tools are a set of Python-based routines and interfaces whose purpose is to provide user-friendly access to the SKA Simulated Skies (S3) set of simulations, an effort led by…
Compactness of Cold Gas in High-Redshift Galaxies
Danail Obreschkow, Steve Rawlings
Galaxies in the early Universe were more compact and contained more molecular gas than today. In this paper, we revisit the relation between these empirical findings, and we quanti…
A Virtual Sky with Extragalactic HI and CO Lines for the SKA and ALMA
Danail Obreschkow, Hans-Rainer Kloeckner, Ian Heywood +2
We present a sky simulation of the atomic HI emission line and the first ten CO rotational emission lines of molecular gas in galaxies beyond the Milky Way. The simulated sky field…
Prediction of the Cosmic Evolution of the CO-Luminosity Functions
D. Obreschkow, I. Heywood, H. -R. Kloeckner +1
We predict the emission line luminosity functions (LFs) of the first 10 rotational transitions of CO in galaxies at redshift z=0 to z=10. This prediction relies on a recently prese…
Simulation of the Cosmic Evolution of Atomic and Molecular Hydrogen in Galaxies
D. Obreschkow, D. Croton, G. De Lucia +2
We present a simulation of the cosmic evolution of the atomic and molecular phases of the cold hydrogen gas in about 3e7 galaxies, obtained by post-processing the virtual galaxy ca…
The Cosmic Decline in the H2/HI-Ratio in Galaxies
D. Obreschkow, S. Rawlings
We use a pressure-based model for splitting cold hydrogen into its atomic (HI) and molecular (H2)components to tackle the co-evolution of HI, H2, and star formation rates (SFR) in…
