KiDS+VIKING-450 and DES-Y1 combined: Mitigating baryon feedback uncertainty with COSEBIs
Marika Asgari, Tilman Tröster, Catherine Heymans +12
We present cosmological constraints from a joint cosmic shear analysis of the Kilo-Degree Survey (KV450) and the Dark Energy Survey (DES-Y1), conducted using Complete Orthogonal Se…
The SPTpol Extended Cluster Survey
L. E. Bleem, S. Bocquet, B. Stalder +135
We describe the observations and resultant galaxy cluster catalog from the 2770 deg SPTpol Extended Cluster Survey (SPT-ECS). Clusters are identified via the Sunyaev-Zel'dovich…
Cosmology from large-scale structure: Constraining CDM with BOSS
Tilman Tröster, Ariel. G. Sánchez, Marika Asgari +9
We reanalyse the anisotropic galaxy clustering measurement from the Baryon Oscillation Spectroscopic Survey (BOSS), demonstrating that using the full shape information provides cos…
Modelling baryonic feedback for survey cosmology
Nora Elisa Chisari, Alexander J. Mead, Shahab Joudaki +10
Observational cosmology in the next decade will rely on probes of the distribution of matter in the redshift range between to elucidate the nature of dark matter and dark e…
KiDS+VIKING-450 and DES-Y1 combined: Cosmology with cosmic shear
S. Joudaki, H. Hildebrandt, D. Traykova +12
We present a combined tomographic weak gravitational lensing analysis of the Kilo Degree Survey (KV450) and the Dark Energy Survey (DES-Y1). We homogenize the analysis of these two…
Implications of a transition in the dark energy equation of state for the and tensions
Ryan E. Keeley, Shahab Joudaki, Manoj Kaplinghat +1
We explore the implications of a rapid appearance of dark energy between the redshifts () of one and two on the expansion rate and growth of perturbations. Using both Gaussian p…
