Extracting Galaxy Cluster Gas Inhomogeneity from X-ray Surface Brightness: A Statistical Approach and Application to Abell 3667
Hajime Kawahara, Erik D. Reese, Tetsu Kitayama +2
Our previous analysis indicates that small-scale fluctuations in the intracluster medium (ICM) from cosmological hydrodynamic simulations follow the lognormal distribution. In orde…
Properties of polycyclic aromatic hydrocarbons in local elliptical galaxies revealed by the Infrared Spectrograph on Spitzer
H. Kaneda, T. Onaka, I. Sakon +3
We performed mid-infrared spectroscopic observations of 18 local dusty elliptical galaxies by using the Infrared Spectrograph (IRS) on board Spitzer. We have significantly detected…
Suzaku broad-band spectroscopy of RX J1347.5-1145: constraints on the extremely hot gas and non-thermal emission
N. Ota, K. Murase, T. Kitayama +6
We present the results from the analysis of long Suzaku observations of the most X-ray luminous galaxy cluster RX J1347.5-1145 at z=0.451. Aims: We study physical properties of the…
A bright, dust-obscured, millimeter-selected galaxy beyond the Bullet Cluster (1E0657-56)
G. W. Wilson, D. Hughes, I. Aretxaga +24
Deep 1.1 mm continuum observations of 1E0657-56 (the "Bullet Cluster") taken with the millimeter-wavelength camera AzTEC on the 10-m Atacama Submillimeter Telescope Experiment (AST…
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…
