Optimizing high redshift galaxy surveys for environmental information
Tobias J. Looser, Simon J. Lilly, Larry P. T. Sin +3
We investigate the performance of group finding algorithms that reconstruct galaxy groups from the positional information of tracer galaxies that are observed in redshift surveys c…
Joint galaxy-galaxy lensing and clustering constraints on galaxy formation
Malin Renneby, Bruno M. B. Henriques, Stefan Hilbert +5
We compare predictions for galaxy-galaxy lensing profiles and clustering from the Henriques et al. (2015) public version of the Munich semi-analytical model of galaxy formation (SA…
Galaxy and Mass Assembly (GAMA): halo formation times and halo assembly bias on the cosmic web
Rita Tojeiro, Elizabeth Eardley, John A. Peacock +10
We present evidence for halo assembly bias as a function of geometric environment. By classifying GAMA galaxy groups as residing in voids, sheets, filaments or knots using a tidal…
A weak gravitational lensing recalibration of the scaling relations linking the gas properties of dark halos to their mass
Wenting Wang, Simon White, Rachel Mandelbaum +3
We use weak gravitational lensing to measure mean mass profiles around Locally Brightest Galaxies (LBGs). These are selected from the SDSS/DR7 spectroscopic and photometric catalog…
Satellite abundances around bright isolated galaxies II: radial distribution and environmental effects
Wenting Wang, Laura V. Sales, Bruno M. B. Henriques +1
We use the SDSS/DR8 galaxy sample to study the radial distribution of satellite galaxies around isolated primaries, comparing to semi-analytic models of galaxy formation based on t…
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…
