What Can Gamma Ray Bursts Teach Us About Dark Energy?
Dan Hooper, Scott Dodelson
It has been suggested that Gamma Ray Bursts (GRB) may enable the expansion rate of our Universe to be measured out to very high redshifts ($z \gsim 5$) just as type Ia supernovae h…
Learning from the Scatter in Type Ia Supernovae
Scott Dodelson, Alberto Vallinotto
Type Ia Supernovae are standard candles so their mean apparent magnitude has been exploited to learn about the redshift-distance relationship. Besides intrinsic scatter in this sta…
Reduced Shear Power Spectrum
Scott Dodelson, Charles Shapiro, Martin White
Measurements of ellipticities of background galaxies are sensitive to the reduced shear, the cosmic shear divided by where is the projected density field. We compute th…
Precision of Inflaton Potential Reconstruction from CMB Using the General Slow-Roll Approximation
Kenji Kadota, Scott Dodelson, Wayne Hu +1
Through a principal component analysis, we study how accurately CMB observables can constrain inflaton potentials in a model independent manner. We apply the general slow-roll appr…
Second Order Geodesic Corrections to Cosmic Shear
S. Dodelson, E. W. Kolb, S. Matarrese +2
We consider the impact of second order corrections to the geodesic equation governing gravitational lensing. We start from the full second order metric, including scalar, vector an…
The Weak Lensing Bispectrum
Scott Dodelson, Pengjie Zhang
Weak gravitational lensing of background galaxies offers an excellent opportunity to study the intervening distribution of matter. While much attention to date has focused on the t…
