Modelling Lyman a forest cross-correlations with LyMAS

© 2016 The Authors. We use the Lya Mass Association Scheme (LyMAS) to predict cross-correlations at z = 2.5 between dark matter haloes and transmitted flux in the Lya forest, and compare to crosscorrelations measured for quasars and damped Lya systems (DLAs) from the Baryon Oscillation Spectroscopic Survey (BOSS) by Font-Ribera et al. We calibrate LyMAS using Horizon-AGN hydrodynamical cosmological simulations of a (100 h -1 Mpc) 3 comoving volume. We apply this calibration to a (1 h -1 Gpc) 3 simulation realized with 2048 3 dark matter particles. In the 100 h -1 Mpc box, LyMAS reproduces the halo-flux correlations computed from the full hydrodynamic gas distribution very well. In the 1 h -1 Gpc box, the amplitude of the large-scale cross-correlation tracks the halo bias b h as expected. We provide empirical fitting functions that describe our numerical results. In the transverse separation bins used for the BOSS analyses, LyMAS cross-correlation predictions follow linear theory accurately down to small scales. Fitting the BOSS measurements requires inclusion of random velocity errors; we find best-fitting rms velocity errors of 399 and 252 km s-1 for quasars and DLAs, respectively. We infer bias-weighted mean halo masses of M h /10 12 h -1 M⊙ = 2.19 +0.16 -0.15 and 0.69 +0.16 -0.14 for the host haloes of quasars and DLAs, with ~0.2 dex systematic uncertainty associated with redshift evolution, intergalactic medium parameters, and selection of data fitting range.

Radio continuum surveys and galaxy evolution: Modelling and simulations

Proceedings of Science 20-23-October-2015 (2016)

A Slyz, J Devriendt, M Jarvis, Y Dubois, C Pichon

We predict the evolution of the radio continuum sky at 1.4 GHz from the Horizon-AGN Adaptive Mesh Refinement (AMR) cosmological hydrodynamical simulation of a cubic volume of the Universe 100h -1 Mpc on a side. With empirically motivated models for the radio continuum emission due to both star formation and Active Galactic Nuclei (AGN), we estimate the contribution of each of these processes to the local radio continuum luminosity function (LF) and describe its evolution up to redshift 4. Despite the simplicity of these models, we find that our predictions for the local luminosity function are fairly consistent with Mauch & Sadler (2007) observations, with the faint end of the luminosity function dominated by star forming galaxies and the bright end by radio loud AGNs. At redshift one, a decent match to Smolcic et al. (2009) VLA data in the COSMOS field can only be achieved when we account for radio continuum emission from AGNs. We predict that the strongest evolution across the peak epoch of cosmic activity happens for low luminosity star forming galaxies L1:4GHz < 10 22 WHz -1 , whose contribution rises until z2 and declines at higher redshifts. The contribution of low luminosity AGNs L1:4GHz < 10 22 W Hz -1 steadily declines from z = 0 throughout the redshift range, whilst that of radio loud objects with luminosities in the range 10 22 W Hz -1 < L 1:4GHz < 10 24 W Hz -1 rises dramatically until z = 4. Finally, high-luminosity radio loud AGNs, with L1:4GHz > 10 24 W Hz -1 show surprisingly little evolution from z = 0 to z = 4.
