MEDUSA: Minkowski functionals estimated from Delaunay tessellations of the three-dimensional large-scale structure
Martha Lippich, Ariel G. Sánchez
Minkowski functionals (MFs) are a set of statistics that characterise the geometry and topology of the cosmic density field and contain complementary information to the standard tw…
KiDS-1000 Cosmology: constraints beyond flat CDM
Tilman Tröster, Marika Asgari, Chris Blake +26
We present constraints on extensions to the flat CDM cosmological model by varying the spatial curvature , the sum of the neutrino masses , the dark energy equati…
KiDS-1000 Cosmology: Multi-probe weak gravitational lensing and spectroscopic galaxy clustering constraints
Catherine Heymans, Tilman Tröster, Marika Asgari +31
We present a joint cosmological analysis of weak gravitational lensing observations from the Kilo-Degree Survey (KiDS-1000), with redshift-space galaxy clustering observations from…
Redshift-space effects in voids and their impact on cosmological tests. Part I: the void size function
Carlos M. Correa, Dante J. Paz, Ariel G. Sánchez +3
Voids are promising cosmological probes. Nevertheless, every cosmological test based on voids must necessarily employ methods to identify them in redshift space. Therefore, redshif…
The Completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: BAO and RSD measurements from anisotropic clustering analysis of the Quasar Sample in configuration space between redshift 0.8 and 2.2
Jiamin Hou, Ariel G. Sánchez, Ashley J. Ross +27
We measure the anisotropic clustering of the quasar sample from Data Release 16 (DR16) of the Sloan Digital Sky Survey IV extended Baryon Oscillation Spectroscopic Survey (eBOSS).…
