Breaking degeneracies with the Sunyaev-Zeldovich full bispectrum
Andrea Ravenni, Matteo Rizzato, Slađana Radinović +3
Non-Gaussian (NG) statistics of the thermal Sunyaev-Zeldovich (tSZ) effect carry significant information which is not contained in the power spectrum. Here, we perform a joint Fish…
The impact of signal-to-noise, redshift, and angular range on the bias of weak lensing 2-point functions
Amy J. Louca, Elena Sellentin
Weak lensing data follow a naturally skewed distribution, implying the data vector most likely yielded from a survey will systematically fall below its mean. Although this effect i…
KiDS-1000 Methodology: Modelling and inference for joint weak gravitational lensing and spectroscopic galaxy clustering analysis
B. Joachimi, C. -A. Lin, M. Asgari +24
We present the methodology for a joint cosmological analysis of weak gravitational lensing from the fourth data release of the ESO Kilo-Degree Survey (KiDS-1000) and galaxy cluster…
Galactic potential constraints from clustering in action space of combined stellar stream data
Stella Reino, Elena M. Rossi, Robyn E. Sanderson +4
Stream stars removed by tides from their progenitor satellite galaxy or globular cluster act as a group of test particles on neighboring orbits, probing the gravitational field of…
Extreme data compression while searching for new physics
Alan Heavens, Elena Sellentin, Andrew Jaffe
Bringing a high-dimensional dataset into science-ready shape is a formidable challenge that often necessitates data compression. Compression has accordingly become a key considerat…
Report from the Tri-Agency Cosmological Simulation Task Force
Nick Battaglia, Andrew Benson, Tim Eifler +8
The Tri-Agency Cosmological Simulations (TACS) Task Force was formed when Program Managers from the Department of Energy (DOE), the National Aeronautics and Space Administration (N…
