Model-Independent Reconstruction of Quintessence Potential and Kinetic Energy from DESI DR2 and Pantheon+ Supernovae
Shengjia Wang, Tian-Nuo Li, Tonghua Liu +1
We present a model-independent reconstruction of the quintessence scalar field's dynamics-both its potential and kinetic energy-directly from the latest cosmological observations.…
Probing Cosmology with Weak Lensing Minkowski Functionals
Jan M. Kratochvil, Eugene A. Lim, Sheng Wang +3
In this paper, we show that Minkowski Functionals (MFs) of weak gravitational lensing (WL) convergence maps contain significant non-Gaussian, cosmology-dependent information. To do…
Cosmological Information in Weak Lensing Peaks
Xiuyuan Yang, Jan M. Kratochvil, Sheng Wang +3
Recent studies have shown that the number counts of convergence peaks N(kappa) in weak lensing (WL) maps, expected from large forthcoming surveys, can be a useful probe of cosmolog…
LSST Science Book, Version 2.0
LSST Science Collaboration, Paul A. Abell, Julius Allison +245
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade.…
Constraining Cosmology with High Convergence Regions in Weak Lensing Surveys
Sheng Wang, Zoltán Haiman, Morgan May
We propose to use a simple observable, the fractional area of "hot spots" in weak gravitational lensing mass maps which are detected with high significance, to determine background…
Challenges to the DGP Model from Horizon-Scale Growth and Geometry
Wenjuan Fang, Sheng Wang, Wayne Hu +3
We conduct a Markov Chain Monte Carlo study of the Dvali-Gabadadze-Porrati (DGP) self-accelerating braneworld scenario given the cosmic microwave background (CMB) anisotropy, super…
