Extending Recovery of the Primordial Matter Power Spectrum
Jaiyul Yoo, David H. Weinberg, Jeremy L. Tinker +2
The shape of the primordial matter power spectrum Plin(k) encodes critical information on cosmological parameters. At large scales, the observable galaxy power spectrum Pobs(k) is…
Complete Treatment of Galaxy Two-Point Statistics: Gravitational Lensing Effects and Redshift-Space Distortions
Jaiyul Yoo
We present a coherent theoretical framework for computing gravitational lensing effects and redshift-space distortions in an inhomogeneous universe and investigate their impacts on…
Improved estimation of cluster mass profiles from the cosmic microwave background
Jaiyul Yoo, Matias Zaldarriaga
We develop a new method for reconstructing cluster mass profiles and large-scale structure from the cosmic microwave background (CMB). By analyzing the likelihood of CMB lensing, w…
From Galaxy-Galaxy Lensing to Cosmological Parameters
Jaiyul Yoo, Jeremy L. Tinker, David H. Weinberg +3
Galaxy-galaxy lensing measures the mean excess surface density DS(r) around a sample of lensing galaxies. We develop a method for combining DS(r) with the galaxy correlation functi…
Constraints on Planetary Companions in the Magnification A=256 Microlensing Event: OGLE-2003-BLG-423
Jaiyul Yoo, D. L. DePoy, A. Gal-Yam +16
We develop a new method of modeling microlensing events based on a Monte Carlo simulation that incorporates both a Galactic model and the constraints imposed by the observed charac…
OGLE-2003-BLG-262: Finite-Source Effects from a Point-Mass Lens
Jaiyul Yoo, D. L. DePoy, A. Gal-Yam +16
We analyze OGLE-2003-BLG-262, a relatively short, t_E=12.5+-0.1day, microlensing event generated by a point-mass lens transiting the face of a K giant source in the Galactic bulge.…
The End of the MACHO Era: Limits on Halo Dark Matter from Stellar Halo Wide Binaries
Jaiyul Yoo, Julio Chaname, Andrew Gould
We simulate the evolution of halo wide binaries in the presence of MAssive Compact Halo Objects (MACHOs) and compare our results to the sample of wide binaries of Chaname & Gould (…
