Voids in Redshift Space
Masatoshi Shoji, Jounghun Lee
We study the ellipticity probability distribution function (PDF) of voids in redshift space with galaxies as tracers of the shapes of voids. We find that the redshift space distort…
Massive Neutrinos in Cosmology: Analytic Solutions and Fluid Approximation
Masatoshi Shoji, Eiichiro Komatsu
We study the evolution of linear density fluctuations of free-streaming massive neutrinos at redshift of z<1000, with an explicit justification on the use of a fluid approximation.…
Disk-Jet Connection in the Radio Galaxy 3C 120
Ritaban Chatterjee, Alan P. Marscher, Svetlana G. Jorstad +33
We present the results of extensive multi-frequency monitoring of the radio galaxy 3C 120 between 2002 and 2007 at X-ray, optical, and radio wave bands, as well as imaging with the…
Third-order Perturbation Theory With Non-linear Pressure
Masatoshi Shoji, Eiichiro Komatsu
We calculate the non-linear matter power spectrum using the 3rd-order perturbation theory without ignoring the pressure gradient term. We consider a semi-realistic system consistin…
How Polarization and Scattering can reveal Geometries, Dynamics, and Feeding of Active Galactic Nuclei
R. W. Goosmann, C. M. Gaskell, M. Shoji
Gaskell et al. (2007) introduced polarization reverberation mapping as a new technique to explore the structure of active galactic nuclei. We present modeling results for the time-…
Extracting Angular Diameter Distance and Expansion Rate of the Universe from Two-dimensional Galaxy Power Spectrum at High Redshifts: Baryon Acoustic Oscillation Fitting versus Full Modeling
Masatoshi Shoji, Donghui Jeong, Eiichiro Komatsu
We present a method for extracting the angular diameter distances, , and the expansion rates, , of the universe from the {\it two-dimensional} Baryon Acoustic Oscillations…
