Magnification as a Tool in Weak Lensing
Alberto Vallinotto, Scott Dodelson, Pengjie Zhang
Weak lensing surveys exploit measurements of galaxy ellipticities. These measurements are subject to errors which degrade the cosmological information that can be extracted from th…
Weighing the spatial and temporal fluctuations of the dark universe
Pengjie Zhang, Rachel Bean, Michele Liguori +1
A generic prediction of the standard cosmology, based on general relativity (GR), dark matter and the cosmological constant (and more generally, smooth dark energy), is that, the t…
A discriminating probe of gravity at cosmological scales
Pengjie Zhang, Michele Liguori, Rachel Bean +1
The standard cosmological model is based on general relativity and includes dark matter and dark energy. An important prediction of this model is a fixed relationship between the g…
