The Effect of Assembly Bias on Redshift Space Distortions
Nelson Padilla, Sergio Contreras, Idit Zehavi +2
We study potential systematic effects of assembly bias on cosmological parameter constraints from redshift space distortion measurements. We use a semi-analytic galaxy formation mo…
Correcting for Fibre Assignment Incompleteness in the DESI Bright Galaxy Survey
Alex Smith, Jian-hua He, Shaun Cole +11
The Dark Energy Spectroscopic Instrument (DESI) Bright Galaxy Survey (BGS) will be a survey of bright, low redshift galaxies, which is planned to cover an area of ~14,000 sq deg in…
The PAU Survey: Early demonstration of photometric redshift performance in the COSMOS field
M. Eriksen, A. Alarcon, E. Gaztanaga +22
The PAU Survey (PAUS) is an innovative photometric survey with 40 narrow bands at the William Herschel Telescope (WHT). The narrow bands are spaced at 100Å intervals covering the r…
The PAU Survey: Spectral features and galaxy clustering using simulated narrow band photometry
L. Stothert, P. Norberg, C. M. Baugh +14
We present a mock catalogue for the Physics of the Accelerating Universe Survey (PAUS) and use it to quantify the competitiveness of the narrow band imaging for measuring spectral…
The impact of assembly bias on the halo occupation in hydrodynamical simulations
M. Celeste Artale, Idit Zehavi, Sergio Contreras +1
We investigate the variations in galaxy occupancy of the dark matter haloes with the large-scale environment and halo formation time, using two state-of-the-art hydrodynamical cosm…
Galaxy Tagging: photometric redshift refinement and group richness enhancement
P. R. Kafle, A. S. G. Robotham, S. P. Driver +4
We present a new scheme, , for refining the photometric redshift measurements of faint galaxies by probabilistically tagging them to observed galaxy groups constructed…
