The Mass-Concentration-Redshift Relation of Cold Dark Matter Halos
Aaron D. Ludlow, Julio F. Navarro, Raul E. Angulo +4
We use the Millennium Simulation series to investigate the mass and redshift dependence of the concentration of equilibrium cold dark matter (CDM) halos. We extend earlier work on…
Galaxy formation on the largest scales: The impact of astrophysics on the BAO peak
Raul E. Angulo, Simon D. M. White, Volker Springel +1
We investigate the effects of galaxy formation on the baryonic acoustic oscillations (BAO) peak by applying semi-analytic modelling techniques to the Millennium-XXL, a $3 \times 10…
Planck 2013 results. XXX. Cosmic infrared background measurements and implications for star formation
Planck Collaboration, P. A. R. Ade, N. Aghanim +238
We present new measurements of CIB anisotropies using Planck. Combining HFI data with IRAS, the angular auto- and cross frequency power spectrum is measured from 143 to 3000 GHz, a…
Modelling Element Abundances in Semi-analytic Models of Galaxy Formation
Robert M. Yates, Bruno Henriques, Peter A. Thomas +3
We update the treatment of chemical evolution in the Munich semi-analytic model, L-GALAXIES. Our new implementation includes delayed enrichment from stellar winds, supernovae type…
Estimating gas masses and dust-to-gas ratios from optical spectroscopy
Jarle Brinchmann, Stéphane Charlot, Guinevere Kauffmann +3
We present a method to estimate the total gas column density, dust-to-gas and dust-to-metal ratios of distant galaxies from rest-frame optical spectra. The technique exploits the s…
Evolution of Galaxies and their Environments at z = 0.1 to 3 in COSMOS
N. Scoville, S. Arnouts, H. Aussel +43
Large-scale structures (LSS) out to z are measured in the Cosmic Evolution Survey (COSMOS) using extremely accurate photometric redshifts (photoz). The Ks-band selected sam…
Planck 2013 results. XVIII. Gravitational lensing-infrared background correlation
Planck Collaboration, P. A. R. Ade, N. Aghanim +223
The multi-frequency capability of the Planck satellite provides information both on the integrated history of star formation (via the cosmic infrared background, or CIB) and on the…
Galactic accretion and the outer structure of galaxies in the CDM model
Andrew P. Cooper, Richard D'Souza, Guinevere Kauffmann +5
We have combined the semi-analytic galaxy formation model of Guo et al. (2011) with the particle-tagging technique of Cooper et al. (2010) to predict galaxy surface brightness prof…
Planck 2013 results. XXI. All-sky Compton parameter power spectrum and high-order statistics
Planck Collaboration, P. A. R. Ade, N. Aghanim +235
We have constructed the first all-sky map of the thermal Sunyaev-Zeldovich (tSZ) effect by applying specifically tailored component separation algorithms to the 100 to 857 GHz freq…
Planck 2013 results. XVII. Gravitational lensing by large-scale structure
Planck Collaboration, P. A. R. Ade, N. Aghanim +235
On the arcminute angular scales probed by Planck, the CMB anisotropies are gently perturbed by gravitational lensing. Here we present a detailed study of this effect, detecting len…
Planck 2013 results. VI. High Frequency Instrument data processing
Planck Collaboration, P. A. R. Ade, N. Aghanim +235
We describe the processing of the 531 billion raw data samples from the High Frequency Instrument (hereafter HFI), which we performed to produce six temperature maps from the first…
Numerical resolution limits on subhalo abundance matching
Qi Guo, Simon White
Subhalo abundance matching (SHAM) inserts galaxies into dark matter only simulations of the growth of cosmic structure in a way that requires minimal assumptions about galaxy forma…
The Mass Profile and Accretion History of Cold Dark Matter Halos
Aaron D. Ludlow, Julio F. Navarro, Michael Boylan-Kolchin +6
We use the Millennium Simulation series to study the relation between the accretion history (MAH) and mass profile of cold dark matter halos. We find that the mean density within t…
The Growth in Size and Mass of Cluster Galaxies since z=2
Chervin F. P. Laporte, Simon D. M. White, Thorsten Naab +1
We study the formation and evolution of Brightest Cluster Galaxies starting from a population of quiescent ellipticals and following them to . To this end, we use a suit…
Exploring the non-linear density field in the Millennium simulations with tessellations - I. The probability distribution function
Biswajit Pandey, Simon D. M. White, Volker Springel +1
We use the Delaunay Tessellation Field Estimator (DTFE) to study the one-point density distribution functions of the Millennium (MS) and Millennium-II (MS-II) simulations. The DTFE…
