BL Lac Objects in the Sloan Digital Sky Survey (SDSS)
A. C. Gupta, W. Yuan, X. Dong +3
We collected a sample of 661 confirmed and 361 possible BL Lac candidates from the recent catalog of BL Lac objects (Veron-Cetty & Veron 2006). We searched these sources in the rec…
Broad-line AGNs with Candidate Intermediate-mass Black holes in the Sloan Digital Sky Survey
Xiaobo Dong, Tinggui Wang, Weimin Yuan +5
We have conducted a systematic search of AGNs with IMBHs from the SDSS DR4. As results we found 245 candidates of broad-line AGN with M_{BH}<10^6 \Msun estimated from the luminosit…
Systematic study of a large sample of NLS1 galaxies from SDSS: first results
Weimin Yuan, Hongyan Zhou, Tinggui Wang +6
This proceedings contribution summarizes first results obtained from a systematic study of 2011 NLS1 galaxies, as presented in Zhou et al. (2006, ApJS 166, 128). The sample was com…
Observations of AGNs using PACT
D. Bose, V. R. Chitnis, P. R. Vishwanath +5
We report our observations on 4 AGNs viz, Mkn421, Mkn501, 1ES1426+428 and ON231 belonging to a sub-class called blazars. The observations were carried out using the Pachmarhi Array…
Blue Straggler Stars in Galactic Open Clusters and the Simple Stellar Population Model
Y. Xin, L. Deng, Z. Han
Blue straggler stars present as secure members in the Galactic open clusters form a major challenge to the conventional picture of evolutionary population synthesis based on the st…
New, nearby bright southern ultracool dwarfs
T. R. Kendall, H. R. A. Jones, D. J. Pinfield +5
We report the discovery of twenty-one hitherto unknown bright southern ultracool dwarfs with spectral types in the range M7 to L5.5, together with new observations of a further thr…
An inner disk below the ADAF: the intermediate spectral state of black hole accretion
B. F. Liu, ; F. Meyer, E. Meyer-Hofmeister
Aims: The hard and soft spectral states of black hole accretion are understood as connected with ADAF accretion (truncated disk) and standard disk accretion, respectively. However,…
Orbital Evolution of Algol Binaries with a Circumbinary Disk
Wen-Cong Chen, Xiang-Dong Li, Sheng-Bang Qian
It is generally thought that conservative mass transfer in Algol binaries causes their orbits to be wider, in which the less massive star overflows its Roche-lobe. The observed dec…
Binary Stellar Population Synthesis Study of Elliptical Galaxies
Zhongmu Li, Fenghui Zhang, Zhanwen Han
We determine relative stellar ages and metallicities mainly for about 80 elliptical galaxies in low and high density environments via the latest binary stellar population (BSP) syn…
Envelope Expansion with Core Collapse. III. Similarity Isothermal Shocks in a Magnetofluid
Cong Yu, Yu-Qing Lou, Fu-Yan Bian +1
We explore MHD solutions for envelope expansions with core collapse (EECC) with isothermal MHD shocks in a quasi-spherical symmetry and outline potential astrophysical applications…
Relative spectral lag: an new redshift indicator to measure the cosmos with gamma-ray bursts
Zhi-Bin Zhang, Jia-Gan Deng, Rui-Jing Lu +1
Using 64 ms count data for long gamma-ray bursts (2.6s), we analyze the quantity, relative spectral lag (RSL), which is defined as , where is t…
Superhumps Behavior during Normal Outbursts in ER UMa: Spectroscopy and Photometry
Yinghe Zhao, Zongyun Li, Xiaoan Wu +4
We have taken a 4-day spectroscopic observation and have been conducting a 13-day photometric study of the SU UMa-type dwarf nova, ER Ursae Majoris. The mean -amplitude for the…
Constraints on SN Ia progenitor time delays from high-z SNe and the star formation history
F. Förster, C. Wolf, Ph. Podsiadlowski +1
We re-assess the question of a systematic time delay between the formation of the progenitor and its explosion in a type Ia supernova (SN Ia) using the Hubble Higher-z Supernova Se…
