Systematic Errors in the Hubble Constant Measurement from the Sunyaev-Zel'dovich effect
Hajime Kawahara, Tetsu Kitayama, Shin Sasaki +1
The Hubble constant estimated from the combined analysis of the Sunyaev-Zel'dovich effect and X-ray observations of galaxy clusters is systematically lower than those from other me…
The Habitat Segregation between Lyman Break Galaxies and Lyman alpha Emitters around a QSO at z~5
Nobunari Kashikawa, Tetsu Kitayama, Mamoru Doi +3
We carried out a target survey for Lyman break galaxies (LBGs) and Lyman alpha emitters (LAEs) around QSO SDSS J0211-0009 at z=4.87. The deep and wide broadband and narrowband imag…
Early Cosmological HII/HeIII Regions and Their Impact on Second-Generation Star Formation
Naoki Yoshida, S. Peng Oh, Tetsu Kitayama +1
(Abridged) We present the results of three-dimensional radiation-hydrodynamics simulations of the formation and evolution of early HII/HeIII regions around the first stars. Cooling…
DIOS: the Diffuse Intergalactic Oxygen Surveyor
T. Ohashi, M. Ishida, S. Sasaki +14
We present our proposal for a small X-ray mission DIOS (Diffuse Intergalactic Oxygen Surveyor), consisting of a 4-stage X-ray telescope and an array of TES microcalorimeters, coole…
