Discovery of A candidate Hypervelocity star originated from the Sagittarius Dwarf Spheroidal galaxy
Yang Huang, Qingzheng Li, Huawei Zhang +5
In this letter, we report the discovery of an intriguing HVS (J1443+1453) candidate that is probably from the Sagittarius Dwarf Spheroidal galaxy (Sgr dSph). The star is an old and…
Intrinsic Morphology of Ultra-diffuse Galaxies
Yu Rong, Xiao-Yu Dong, Thomas H. Puzia +10
With the published data of apparent axis ratios for 1109 ultra-diffuse galaxies (UDGs) located in 17 low-redshift (z~ 0.020 - 0.063) galaxy clusters and 84 UDGs in 2 intermediate-r…
Discovery of An Active Intermediate-Mass Black Hole Candidate in the Barred Bulgeless Galaxy NGC 3319
Ning Jiang, Tinggui Wang, Hongyan Zhou +7
We report the discovery of an active intermediate-mass black hole (IMBH) candidate in the center of nearby barred bulgeless galaxy . The point X-ray source revealed b…
Differences in Halo-Scale Environments between Type 1 and Type 2 AGNs at Low Redshift
Ning Jiang, Huiyuan Wang, Houjun Mo +3
Using low-redshift (z<0.09) samples of AGNs, normal galaxies and groups of galaxies selected from the Sloan Digital Sky Survey (SDSS), we study the environments of type 1 and type…
Anomalously Steep Reddening Law in Quasars: An Exceptional Example Observed in IRAS14026+4341
Peng Jiang, Hongyan Zhou, Tuo Ji +7
A fraction of the heavily reddened quasars require a reddening curve which is even steeper than that of the Small Magellanic Cloud. In this paper, we thoroughly characterize the an…
Dust reddening in star-forming galaxies
Ting Xiao, Tinggui Wang, Huiyuan Wang +3
We present empirical relations between the global dust reddening and other physical galaxy properties including the Halpha luminosity, Halpha surface brightness, metallicity and ax…
