Effects of dark-matter density profiles on bulge formation in very late-type galaxies
Jie-Hao Huang, Zu-Gan Deng, Yan-Ning Fu
The dynamical evolution of super star clusters has been investigated in dark matter halos depicted with a cuspy- or soft-core density profile. The simulations show that (1) exponen…
Soft X-ray Properties of ULIRGs Based on a Large and Complete Sample
X. -Y. Xia, Th. Boller, Z. -G. Deng +1
We report on the results of the cross-correlation of a sample of 903 Ultraluminous IRAS galaxies (ULIRGs) with the ROSAT-All Sky Survey Bright Source Catalogue and the ROSAT archiv…
An HST Surface Photometric Study of Ultraluminous Infrared Galaxies
Z. Zheng, H. Wu, S. Mao +3
We study the surface photometry for 13 single-nucleus ultraluminous IRAS galaxies (ULIRGs), selected from a parent sample of 58 galaxies obtained in a Hubble Space Telescope snapsh…
Ultraluminous IRAS galaxy 10026+4347
X. -Y. Xia, Shude Mao, H. Wu +4
We study optical and X-ray properties of the ultraluminous IRAS galaxy 10026+4347. This galaxy is a narrow-line QSO with very strong FeII emission. Three optical spectra were taken…
