On the nature of the flares from three candidate tidal disruption events
Y. Lu, Z. Zheng, S. N. Zhang +1
The X-ray flares of NGC 5905, RX J1242.6-1119A, and RX J1624.9+7554 observed by Chandra in 2001 and 2002 have been suggested as the candidate tidal disruption events. The distinct…
Age constraints for an M31 globular cluster from SEDs-fit
Jun Ma, Yanbin Yang, David Burstein +4
We have constrained the age of the globular cluster S312 in the Andromeda galaxy (M31) by comparing its multicolor photometry with theoretical stellar population synthesis models.…
Making a Short Gamma-Ray Burst from a Long one: Implications for the Nature of GRB 060614
Bing Zhang, Bin-Bin Zhang, En-Wei Liang +3
The absence of a supernova accompanying the nearby long GRB 060614 poses a great puzzle about the progenitor of this event and challenges the current GRB classification scheme. Thi…
531 new spectroscopic redshifts from the CDFS and a test on the cosmological relevance of the GOODS-South field
C. D. Ravikumar, M. Puech, H. Flores +23
(Abbrev.) This paper prepares a series of papers analysing the Intermediate MAss Galaxy Evolution Sequence (IMAGES) up to z=1. Intermediate mass galaxies (MJ <=-20.3) are selected…
Optical Monitoring of BL Lacertae Object S5 0716+714 with a Novel Multi-Peak Interference Filter
Jianghua Wu, Xu Zhou, Jun Ma +3
We at first introduce a novel photometric system, which consists of a Schmidt telescope, an objective prism, a CCD camera, and, especially, a multi-peak interference filter. The mu…
Possible Streams of the Globular Clusters in the Galaxy
Shuang Gao, Bi-Wei Jiang, Yong-Heng Zhao
This paper aims to retrieve the ghost streams under the pre-assumption that all the globular clusters in our Galaxy were formed in the very early merge events. The results are base…
Characteristics of supernova remnant G351.7+0.8 and a distance argument against its association with PSR J1721-3532
W. W. Tian, M. Haverkorn, H. Y. Zhang
New images of the supernova remnant (SNR) G351.7+0.8 are presented based on 21cm HI-line emission and continuum emission data from the Southern Galactic Plane Survey (SGPS). SNR G3…
A comprehensive analysis of Swift/XRT data: I. Apparent spectral evolution of GRB X-ray tails
Bin-Bin Zhang, En-Wei Liang, Bing Zhang
An early steep decay component following the prompt GRBs is commonly observed in {\em Swift} XRT light curves, which is regarded as the tail emission of the prompt gamma-rays. Prom…
Candidate Milky Way Satellites in the Galactic Halo
C. Liu, J. Hu, H. Newberg +1
Sloan Digital Sky Survey (SDSS) DR5 photometric data with , are searched for new Milky Way companions or substructures in…
On Secular Resonances of Small Bodies in the Planetary Systems
Ji Jianghui, Liu Lin, Li Guangyu
We investigate the secular resonances for massless small bodies and Earth-like planets in several planetary systems. We further compare the results with those of Solar System. For…
Measuring Neutron Star Mass and Radius with Three Mass-Radius Relations
C. M. Zhang, H. X. Yin, Y. Kojima +5
We propose to determine the mass and the radius of a neutron star (NS) using three measurable mass-radius relationships, namely the ``apparent'' radius inferred from neutron star t…
