We present simultaneous observations of 12CO, 13CO and C180 J=1-0emission in 11 nearby (cz＜1000 km s-1) bright infrared g......
New background quasars in the vicinity of the Andromeda Galaxy discovered with the Guoshoujing Teles
We present preliminary analyses of spectra of quasar candidates in two Guoshoujing Telescope (GSJT, formerly named the L......
By analyzing Chandra X-ray data of a sample of 21 galaxy groups and 19galaxy clusters,we find that in 31 sample systems ......
We make use of the images from the Sloan Digital Sky Survey Stripe 82 (Stripe 82) to present an analysis of r band surfa......
Based on the coexistence of the Blandford-Znajek and magnetic coupling processes in black hole (BH)accretion disc, a mul......
Possible γ-ray emission of radio intermediate AGN Ⅲ Zw 2 and its implication on the evolution of jet
AGNs with hard γ-ray emission identified so far are radio-loud. Ⅲ Zw 2 is a radio intermediate AGN with a relativistic......
We collect a sample of 381(271 type Ⅰ)active galactic nuclei(AGNs)with XMM-Newton observations for an analysis of the d......
We study the ages of a large sample (1802) of nearly face-on disk low sur-face brightness galaxies (LSBGs) using the evo......
We analyze the optical spectrum of type 1 QSO SDSS J1425+3231. This object is interesting since its narrow emission line......
Flux-limited and volume-limited galaxy samples are constructed from theSloan Digital Sky Survey (SDSS) data releases DR4......
We study the regular or chaotic character of orbits in a 3D dynamical model,describing a triaxu1 galaxy surrounded by a ......
The external Compton (EC) model is used to study the high energy emission of some blazars,in which the external photon f......
We test the distance-duality (DD) relation by combining the angular diameter distance DA provided by two galaxy cluster ......
We report the discovery of a broad absorption line (BAL) of ～104 km s-1in width in the previously known BL Lac object PKS......
We identify new strong lensing clusters of galaxies from the Sloan Digital Sky Survey Ⅲ (SDSS DR8) by visually inspecti......
We report the discovery of Balmer broad absorption lines (BALs) in the quasar LBQS 1206+1052 and present a detailed anal......
Clusters of galaxies are the most massive objects in the Universe and precise knowledge of their mass structure is impor......
