Cosmic star formation history associated with QSO activity: an approach using the black hole to bulge mass correlation
Y. P. Wang, T. Yamada, Y. Taniguchi
The tight correlation between the masses of central black holes and their host spheroids in nearby galaxies and active galactic nuclei suggests that black hole growth is closely re…
Special Purpose Pulsar Telescope for the Detection of Cosmic Gravitational Waves
Shou-Guan Wang, Zong-Hong Zhu, Zhen-Long Zou +1
Pulsars can be used to search for stochastic backgrounds of gravitational waves of cosmological origin within the very low frequency band (VLF), to Hz. We propo…
Magnetic fields in AGNs and microquasars
A. F. Zakharov, N. S. Kardashev, V. N. Lukash +1
Observations of AGNs and microquasars by ASCA, RXTE, Chandra and XMM-Newton indicate the existence of wide X-ray emission lines of heavy ionized elements in their spectra. The emis…
Are there cosmological evolution trends on Gamma-Ray Burst features?
D. M. Wei, W. H. Gao
The variability of gamma-ray burst (GRB) is thought to be correlated with its absolute peak luminosity, and this relation had been used to derive an estimate of the redshifts of GR…
Subaru high resolution spectroscopy of complex metal absorption lines of QSO HS1603+3820
Toru Misawa, Toru Yamada, Masahide Takada-Hidai +4
We present a high resolution spectrum of the quasar, HS1603+3820 (z_em=2.542), observed with the High Dispersion Spectrograph (HDS) on Subaru Telescope. This quasar, first discover…
An accretion model for the growth of the central black hole associated with ionization instability in quasars
Y. Lu, K. S. Cheng, S. N. Zhang
A possible accretion model associated with the ionization instability of quasar disks is proposed to address the growth of the central black hole harbored in the host galaxy.The ma…
Spectral Energy Distributions and Age Estimates of 172 Globular Clusters in M31
Linhua Jiang, Jun Ma, Xu Zhou +3
In this paper we present CCD multicolor photometry for 172 globular clusters (GCs), taken from the Bologna catalog (Battistini et al. 1987), in the nearby spiral galaxy M31. The ob…
Can radiative cooling and nongravitational heating explain simultaneously the global X-ray properties of clusters and the unresolved cosmic X-ray background ?
Yan-Jie Xue, Xiang-Ping Wu
Using a simple analytic approach we address the question of whether radiative cooling, nongravitational heating and cooling plus heating models can simultaneously explain the obser…
Formation of bulges in very late-type galaxies from SSCs
Y. N. Fu, J. H. Huang, Z. G. Deng
The dynamical evolution of super star clusters (SSCs) moving in the background of a dark matter halo has been investigated as a possible event responsible for the formation of bulg…
Empirical Population Synthesis for 74 Blue Compact Galaxies
X. Kong
We have observed the largest optical spectra sample of 74 blue compact galaxies. Stellar population properties of them were derived by comparing the equivalent widths of strong abs…
Simultaneous Optical and X-ray Observations of Flares and Rotational Modulation on the RS CVn Binary HR 1099 (V711 Tau) from the MUSICOS 1998 Campaign
D. Garcia-Alvarez, B. H. Foing, D. Montes +2
We present simultaneous and continuous observations of the H, H, He {\sc i} D, Na {\sc i} D,D doublet and the Ca {\sc ii} H & K lines for the RS CVn system…
Statistical Shapes of the Highest Pulses in Gamma--Ray Bursts
Yi-Ping Qin, En-Wei Liang, Guang-Zhong Xie +1
The statistical shapes of the highest pulse have been studied by aligned method. A wavelet package analysis technique and a developed pulse--finding algorithm have been applied to…
Photometric Redshift Determination with the BATC Multicolor System
Lifang Xia, Xu Zhou, Jun Ma +6
In this paper, we present the methodology of photometric redshift determination with the BATC 15-color system by using hyperz program. Both simulated galaxies and real galaxies wit…
15 colour photometry of Landolt SA95 standard star field
Xu Zhou, Zhaoji Jiang, Jun Ma +6
In this paper, we present a set of photometric observations in 15 colors of stars in the Landolt covered by the system range from 300 nm to 1000 nm. Visual magnitudes of the stars…
Intrinsic Degeneracy of Gravitational Lens Time Delays: the case for a simple quadruple system in CDM cosmology
HongSheng Zhao, Bo Qin
A degeneracy in strong lens model is shown analytically. The observed time delays and quasar image positions might {\it not} uniquely determine the concentration and the extent of…
Multicolor photometry of 145 of the HII regions in M33
Linhua Jiang, Jun Ma, Xu Zhou +5
This paper is the first in a series presenting CCD multicolor photometry for 145 HII regions, selected from 369 candidate regions from Boulesteix et al. (1974), in the nearby spira…
Milestones in the Observations of Cosmic Magnetic Fields
J. L. Han, R. Wielebinski
Magnetic fields are observed everywhere in the universe. In this review, we concentrate on the observational aspects of the magnetic fields of Galactic and extragalactic objects. R…
Natural Inflation, Planck Scale Physics and Oscillating Primordial Spectrum
Xiulian Wang, Bo Feng, Mingzhe Li +2
In the ``natural inflation'' model, the inflaton potential is periodic. We show that Planck scale physics may induce corrections to the inflaton potential, which is also periodic w…
Masses, Accretion Rates and Inclinations of AGNs
W. Bian, Y. Zhao
We assume that the gravitational instability of standard thin accretion disks leads to the Broad Line Regions (BLRs), the B band luminosity comes from standard thin disk and the mo…
AE Aquarii: how CVs descend from supersoft binaries
K. Schenker, A. R. King, U. Kolb +2
AE Aquarii is a propeller system. It has the shortest spin period among cataclysmic variables, and this is increasing on a 10^7 yr timescale. Its UV spectrum shows very strong carb…
Dynamical limits on galactic winds, halo machos and intergalactic globular clusters
HongSheng Zhao
We argue that any violent galactic winds following early epoch of star bursts would significantly weaken the potentials of galaxies, and leave lasting signatures such as a lowered…
