Mass Segregation in Star Clusters: Analytic Estimation of the Timescale
H. Mouri, Y. Taniguchi
Mass segregation in a star cluster is studied in an analytical manner. We consider a two-component cluster, which consists of two types of stars with different masses. Plummer's mo…
Gas Metallicity of Narrow-Line Regions in Narrow-Line Seyfert 1 Galaxies and Broad-Line Seyfert 1 Galaxies
Tohru Nagao, Takashi Murayama, Yasuhiro Shioya +1
We investigate gas metallicity of narrow-line regions in narrow-line Seyfert 1 galaxies (NLS1s) and broad-line ones (BLS1s) in order to examine whether or not there is a difference…
Subaru Deep Survey II. Luminosity Functions and Clustering Properties of Lya Emitters at z=4.86 in the Subaru Deep Field
M. Ouchi, K. Shimasaku, H. Furusawa +17
We report on early results from deep and wide-field narrow-band imaging on a 543 arcmin^2 area of the Subaru Deep Field. We find 87 Lya emitters (LAEs) at z=4.86(+/-0.03) which are…
A Multi-band Photometric Study of Tidal Debris in A Compact Group of Galaxies: Seyfert's Sextet
S. Nishiura, Y. Shioya, T. Murayama +4
In order to investigate the properties of the prominent tidal debris feature extending to the northeast of the compact group of galaxies Seyfert's Sextet, we analyzed multi-band (U…
Runaway Merging of Black Holes: Analytical Constraint on the Timescale
H. Mouri, Y. Taniguchi
Following the discovery of a black hole (BH) with a mass of 10^3-10^6 M(sun) in a starburst galaxy M82, we study formation of such a BH via successive merging of stellar-mass BHs w…
