Planck cold clumps in the Orionis complex: I. Discovery of an extremely young Class 0 protostellar object and a proto-brown dwarf candidate in a bright rimmed clump PGCC G192.32-11.88
Tie Liu, Qizhou Zhang, Kee-Tae Kim +37
We are performing a series of observations with ground-based telescopes toward Planck Galactic cold clumps (PGCCs) in the Orionis complex in order to systematically investigate…
A new method to measure the virial factors in the reverberation mapping of AGNs
H. T. Liu, H. C. Feng, J. M. Bai
Based on the gravitational redshift, one prediction of Einstein's general relativity theory, of broad optical emission lines in active galactic nuclei (AGNs), a new method is propo…
Discovery of two broad absorption line quasars at redshift about 4.75 using the Lijiang 2.4m telescope
WeiMin Yi, XueBing Wu, FeiGe Wang +3
The ultraviolet broad absorption lines have been seen in the spectra of quasars at high redshift, and are generally considered to be caused by outflows with velocities from thousan…
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope Quasar Survey: Quasar Properties from First Data Release
Y. L. Ai, Xue-Bing Wu, Jinyi Yang +20
We present preliminary results of the quasar survey in Large Sky Area Multi- Object Fiber Spectroscopic Telescope (LAMOST) first data release (DR1), which includes pilot survey and…
The star-formation history of low-mass disk galaxies: a case study of NGC\,300
Xiaoyu Kang, Fenghui Zhang, Ruixiang Chang +2
Since NGC300 is a bulge-less, isolated low-mass galaxy and has not experienced radial migration during its evolution history, it can be treated as an ideal laboratory to test simpl…
Kinematic properties of the dual AGN system J0038+4128 based on long-slit spectroscopy
Yang-Wei Zhang, Yang Huang, Jin-Ming Bai +2
The study of kiloparsec-scale dual active galactic nuclei (AGN) will provide important clues to understand the co-evolution between the host galaxies and their central supermassive…
Effects of turbulent dust grain motion to interstellar chemistry
J. X. Ge, J. H. He, H. R. Yan
Theoretical studies have revealed that dust grains are usually moving fast through the turbulent interstellar gas, which could have significant effects upon interstellar chemistry…
An ultra-luminous quasar at z=5.363 with a ten billion solar mass black hole and a Metal-Rich DLA at z~5
Feige Wang, Xue-Bing Wu, Xiaohui Fan +11
We report the discovery of an ultra-luminous quasar J030642.51+185315.8 (hereafter J0306+1853) at redshift 5.363, which hosts a super-massive black hole (SMBH) with $M_{BH} = (1.07…
The First Data Release (DR1) of the LAMOST general survey
A. -L. Luo, Y. -H. Zhao, G. Zhao +140
The Large sky Area Multi-Object Spectroscopic Telescope (LAMOST) General Survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and…
Influences of Radiation Pressures on Mass Estimates of Supermassive Black Holes in AGNs
H. T. Liu, H. C. Feng, J. M. Bai
In this paper, we investigate the influences of two continuum radiation pressures of the central engines on the black hole mass estimates for 40 active galactic nuclei (AGNs) with…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. IV. H Time Lags and Implications for Super-Eddington Accretion
Pu Du, Chen Hu, Kai-Xing Lu +13
We have completed two years of photometric and spectroscopic monitoring of a large number of active galactic nuclei (AGNs) with very high accretion rates. In this paper, we report…
Constraints on black hole massess with timescales of variations in blazars
H. T. Liu, J. M. Bai
In this paper, we investigated the issue of black hole masses and minimum timescales of jet emission for blazars. We proposed a sophisticated model that sets an upper limit to the…
The effects of binary interactions on parameter determinations for early-type galaxies
Yu Zhang, Jinzhong Liu, Fenghui Zhang
Based on stellar population models without (SSP) and with (BSP) binary interactions, we investigate the effects of binary interactions on parameter determinations for early-type ga…
Supermassive Black Holes with High Accretion Rates in Active Galactic Nuclei. III. Detection of Fe II Reverberation in Nine Narrow-Line Seyfert 1 Galaxies
Chen Hu, Pu Du, Kai-Xing Lu +8
This is the third in a series of papers reporting on a large reverberation-mapping campaign aimed to study the properties of active galactic nuclei (AGNs) with high accretion rates…
The Evolution of Interacting Spiral Galaxy NGC 5194
Xiaoyu Kang, Ruixiang Chang, Fenghui Zhang +2
NGC 5194 (M51a) is a grand-design spiral galaxy and undergoing interactions with its companion. Here we focus on investigating main properties of its star-formation history (SFH) b…
An ultra-luminous quasar with a twelve-billion-solar-mass black hole at redshift 6.30
Xue-Bing Wu, Feige Wang, Xiaohui Fan +10
So far, roughly 40 quasars with redshifts greater than z=6 have been discovered. Each quasar contains a black hole with a mass of about one billion solar masses (). T…
