Cosmology with High-redshift Galaxy Survey: Neutrino Mass and Inflation
Masahiro Takada, Eiichiro Komatsu, Toshifumi Futamase
(abridged) High-z galaxy redshift surveys open up exciting possibilities for precision determinations of neutrino masses and inflationary models. The high-z surveys are more useful…
Systematic Errors in Future Weak Lensing Surveys: Requirements and Prospects for Self-Calibration
Dragan Huterer, Masahiro Takada, Gary Bernstein +1
We study the impact of systematic errors on planned weak lensing surveys and compute the requirements on their contributions so that they are not a dominant source of the cosmologi…
Can the Steep Mass Profile of A1689 Be Explained by a Triaxial Dark Halo?
Masamune Oguri, Masahiro Takada, Keiichi Umetsu +1
The steep mass profile of A1689 derived from recent detailed lensing observations is not readily reconciled with the low concentration halos predicted by the standard CDM model. Ho…
