The properties of a large sample of low surface brightness galaxies from SDSS (2009)
Liang, Y. C., Zhong, G. H., Chen, X. Y., Gao, D., Hammer, F., Liu, F. S., ...
A large sample of low surface brightness (LSB) disk galaxies is selected from SDSS with B-band central surface brightness mu_0(B) from 22 to 24.5 mag arcsec^(-2). Some of their properties are...
SVOM: a new mission for Gamma-Ray Burst Studies (2009)
Gotz, D., Paul, J., Basa, S., Wei, J., Zhang, S. N., ...

Zhong, G. H., Liang, Y. C., Liu, F. S., Hammer, F., Hu, J. Y., Chen, X. Y., ...
We present the properties of a large sample (12,282) of nearly face-on low surface brightness (LSB) disk galaxies selected from the main galaxy sample of SDSS-DR4. These properties include B-band...
SDSS J121811.0+465501.2: a new Low Surface Brightness Galaxy with low metallicity (2007)
Liang, Y. C., Hu, J. Y., Liu, F. S., Liu, Z. T.
We serendipitously find a new nearby Low Surface Brightness (LSB) galaxy from SDSS database. We estimate oxygen abundance of its H II region SDSS J121811.0+465501.2 from electron temperature, as well...
The structure of the Galactic halo: SDSS versus SuperCOSMOS (2007)
Xu, Y., Deng, L. C., Hu, J. Y.
The halo structure at high Galactic latitudes near both the north and south poles is studied using SDSS and SuperCOSMOS data. For the south cap halo, the archive of the SuperCOSMOS photographic...
The asymmetric structure of the Galactic halo (2006)
Xu, Y., Deng, L. C., Hu, J. Y.
Using the stellar photometry catalogue based on the latest data release (DR4) of the Sloan Digital Sky Survey (SDSS), a study of the Galactic structure using star counts is carried out for selected...
Sun, B., Chen, J.R., Hu, J.Y., Li, X.J.
The stoichiometry of dioxygen uptake of Co complexes with 4',5'-bis-(5-chloro-2-hydroxyphenylmethylideneimino)benzo-12-crown-4 (la), 4',5'-bis(2-hydroxyphenylmethylideneimino)benzo-12-crown-4(1b),...
1RXS J232953.9+062814: a New SU UMa Dwarf Nova below the Period Minimum (2001)
Wei, J. Y., Jiang, X. J., Xu, D. W., Zhou, A. Y., Hu, J. Y.
1RXS J232953.9+062814 was identified as a cataclysmic variable by Wei et al. (1999). Four low-resolution spectra of 1RXS J232953.9+062814 were obtained by using the 2.16-m telescope of the National...
Deng, J. S., Qiu, Y. L., Hu, J. Y., Hatano, K., Branch, D.
Low resolution spectra of SN 1999dn at early times are presented and compared with synthetic spectra generated with the parameterized supernova synthetic-spectrum code SYNOW. We find that the spectra...
A High Peculiarity Rate for Type Ia SNe (1999)
Li, W. D., Filippenko, A. V., Riess, A. G., Hu, J. Y., Qiu, Y. L.
We have compiled a sample of 90 SNe Ia from 1997 to 1999 (up to SN 1999da) and studied the peculiarity rate of SN 1991T, SN 1991bg and SN 1986G-like objects. A Monte Carlo code is written to study...
The Type Ia Supernova 1997br in ESO 576-G40 (1999)
Li, W. D., Qiu, Y. L., Zhu, X. H., Hu, J. Y., Richmond, M. W., ...
The peculiar type Ia supernova SN 1997br in ESO 576-G40 was extensively observed at Beijing Astronomical Observatory and Lick Observatory. In this paper, we present and discuss the BVRI photometry...
Hajjou, M, Hill, K R, Subramaniam, S V, Hu, J Y, Raju, R
The mechanism of RNA-RNA recombination at the 3' nontranslated region (3'NTR) of the Sindbis virus (SIN) genome was studied by using nonreplicative RNA precursors. The 11.7-kb SIN genome was...
Hill, K R, Hajjou, M, Hu, J Y, Raju, R
Sindbis virus (SIN), a mosquito-transmitted animal RNA virus, carries a 11.7-kb positive-sense RNA genome which is capped and polyadenylated. We recently reported that the SIN RNA-dependent RNA...
