Constraints on the Intracluster Dust Emission in the Coma Cluster of Galaxies (2009)
Kitayama, T., Ito, Y., Okada, Y., Kaneda, H., Takahashi, H., Ota, N., ...
We have undertaken a search for the infrared emission from the intracluster dust in the Coma cluster of galaxies by the MIPS on board Spitzer. Our observations yield the deepest mid and far-infrared...
Kaneda, H., Onaka, T., Sakon, I., Kitayama, T., Okada, Y., Suzuki, T.
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 polycyclic...
Ota, N., Murase, K., Kitayama, T., Komatsu, E., Hattori, M., Matsuo, H., ...
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 hot (~20 keV) gas...
A bright, dust-obscured, millimeter-selected galaxy beyond the Bullet Cluster (1E0657-56) (2008)
Wilson, G. W., Hughes, D., Aretxaga, I., Ezawa, H., Austermann, J. E., Doyle, S., ...
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 (ASTE), have revealed...
A bright, dust-obscured, millimetre-selected galaxy beyond the Bullet Cluster (1E0657−56) (2008)
Wilson, G. W., Hughes, D. H., Aretxaga, I., Ezawa, H., Austermann, J. E., Doyle, S., ...
Kaneda, H., Onaka, T., Kitayama, T., Okada, Y., Sakon, I.
We report on mid- and far-IR Spitzer observations of 7 nearby dusty elliptical galaxies by using the Multiband Imaging Photometer (MIPS) and Infrared Spectrograph (IRS). Our sample galaxies are known...
DIOS: the Diffuse Intergalactic Oxygen Surveyor (2006)
Ohashi, T., Ishida, M., Sasaki, S., Ishisaki, Y., Mitsuda, K., Yamasaki, N. Y., ...
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, cooled with mechanical...
The Structure and Evolution of Early Cosmological HII Regions (2004)
Kitayama, T., Yoshida, N., Susa, H., Umemura, M.
We study the formation and evolution of HII regions around the first stars formed at z=10-30. We use a one-dimensional Lagrangian hydrodynamics code which self-consistently incorporates radiative...
Kitayama, T., Komatsu, E., Ota, N., Kuwabara, T., Suto, Y., Yoshikawa, K., ...
Foreseeing the era of high spatial resolution measurements of the Sunyaev-Zel'dovich effect (SZE) in clusters of galaxies, we present a prototype analysis of this sort combined with Chandra X-ray...
Observing H2 Emission in Forming Galaxies (2003)
We study the H2 cooling emission of forming galaxies, and discuss their observability using the future infrared facility SAFIR. Forming galaxies with mass >10^11 Msun emit most of their gravitational...
A new measurement of the X-ray temperature function of clusters of galaxies (2002)
Ikebe, Y., Reiprich, T.H, Böhringer, H., Tanaka, Y., Kitayama, T.
We present a newly measured X-ray temperature function of galaxy clusters using a complete flux-limited sample of 61 clusters. The sample is constructed with the total survey area of 8.14 steradians...
Criteria for the Formation of Population III Objects in the Ultraviolet Background Radiation (2001)
Kitayama, T., Susa, H., Umemura, M., Ikeuchi, S.
We explore possibilities of collapse and star formation in Population III objects exposed to the external ultraviolet background (UVB) radiation. Assuming spherical symmetry, we solve...
Radiation-Hydrodynamical Collapse of Pregalactic Clouds in the Ultraviolet Background (2000)
Kitayama, T., Tajiri, Y., Umemura, M., Susa, H., Ikeuchi, S.
To elucidate the effects of the UV background radiation on the collapse of pregalactic clouds, we implement a radiation-hydrodynamical calculation, combining one-dimensional spherical hydrodynamics...

Mechanisms of pain sensitization and the treatments
Dohi, Toshihiro, Morita, K., Abdin, M.J., Kitayama, T., Motoyama, N., Zohn, R.
Hyperalgesia and allodynia, major symptoms of neuropathic pain can results after nerve injury or chronic inflammation. Trigeminal neuropathic pain resulting from alterations in peripheral and central...
