Galaxy Structures and External Perturbations in Gravitational Lenses
Yozo Kawano, Masamune Oguri, Takahiko Matsubara +1
In modeling strong gravitational lens systems, one often adopts simple models, such as singular isothermal elliptical density plus lowest-order external perturbation. However, such…
Criteria for the Formation of Population III Objects in the Ultraviolet Background Radiation
T. Kitayama, H. Susa, M. Umemura +1
We explore possibilities of collapse and star formation in Population III objects exposed to the external ultraviolet background (UVB) radiation. Assuming spherical symmetry, we so…
Radiation-Hydrodynamical Collapse of Pregalactic Clouds in the Ultraviolet Background
T. Kitayama, Y. Tajiri, M. Umemura +2
To elucidate the effects of the UV background radiation on the collapse of pregalactic clouds, we implement a radiation-hydrodynamical calculation, combining one-dimensional spheri…
Formation of intermediate-mass black holes in circumnuclear regions of galaxies
Yoshiaki Taniguchi, Yasuhiro Shioya, Takeshi G. Tsuru +1
Recent high-resolution X-ray imaging studies have discovered possible candidates of intermediate-mass black holes with masses of $M_\bullet \sim 10^{2-4} \MO$ in circumnuclear regi…
Globular cluster formation triggered by the initial starburst in galaxy formation
Yoshiaki Taniguchi, Neil Trentham, Satoru Ikeuchi
We propose and investigate a new formation mechanism for globular clusters in which they form within molecular clouds that are formed in the shocked regions created by galactic win…
Formation of Sub-galactic Clouds under UV Background Radiation
Tetsu Kitayama, Satoru Ikeuchi
The effects of the UV background radiation on the formation of sub-galactic clouds are studied by means of one-dimensional hydrodynamical simulations. The radiative transfer of the…
