ALMA observations reveal no preferred outflow--filament and outflow--magnetic field orientations
T. Baug, Ke Wang, Tie Liu +12
We present a statistical study on the orientation of outflows with respect to large-scale filaments and the magnetic fields. Although filaments are widely observed toward Galactic…
The growth of bulges and discs in relatively HI-rich galaxies: indication from HI scaling relations
Xinkai Chen, Jing Wang, Xu Kong +3
We study the relation between the properties of the bulge/disc components and the HI mass fraction of galaxies. We find that at fixed stellar mass, disc colours are correlated with…
Kinematic signatures of reverberation mapping of close binaries of supermassive black holes in active galactic nuclei. II. Atlas of two-dimensional transfer functions
Yu-Yang Songsheng, Ming Xiao, Jian-Min Wang +1
Most large galaxies harbor supermassive black holes (SMBHs) in their centers, and galaxies merge. Consequently, binary SMBHs should be common in galactic nuclei. However, close bin…
A PRESTO-based Parallel Pulsar Search Pipeline Used for FAST Drift Scan Data
Qiuyu Yu, Zhichen Pan, Lei Qian +9
We developed a pulsar search pipeline based on PRESTO (PulsaR Exploration and Search Toolkit). This pipeline simply runs dedispersion, FFT (Fast Fourier Transformation), and accele…
SDSS-IV MaNGA: Internal mass distributions and orbital structures of early-type galaxies and their dependence on environment
Yunpeng Jin, Ling Zhu, R. J. Long +3
In our earlier 2019 paper, we evaluated the reliability of Schwarzschild's orbit-superposition dynamical modelling method in estimating the internal mass distribution, intrinsic st…
DEEM, a versatile platform of FRD measurement for highly multiplexed fibre systems in astronomy
Yunxiang Yan, Qi Yan, Gang Wang +6
We present a new method of DEEM, the direct energy encircling method, for characterising the performance of fibres in most astronomical spectroscopic applications. It's a versatile…
A modified method for determining the FRD and length properties of optical fibres in astronomy
Yunxiang Yan, Gang Wang, Weimin Sun +4
Focal ratio degradation (FRD) is a major contributor to throughput and light loss in a fibre spectroscopic telescope system. We combine the guided mode theory in geometric optics a…
Hot subdwarf stars identified in Gaia DR2 with spectra of LAMOST DR6 and DR7 I. Single-lined spectra
Zhenxin Lei, Jingkun Zhao, Péter Németh +1
182 single-lined hot subdwarf stars are identified by using spectra from the sixth and seventh data release (DR6 and DR7) of the Large Sky Area Multi-Object Fibre Spectroscopic Tel…
A catalog of galaxy clusters identified from SCUSS, SDSS, and unWISE
Jinghua Gao, Hu Zou, Xu Zhou +1
This paper presents the identification of galaxy clusters from the photometric redshift catalog based on three imaging surveys of SCUSS, SDSS, and unWISE. By applying a fast cluste…
TOI 564 b and TOI 905 b: Grazing and Fully Transiting Hot Jupiters Discovered by TESS
Allen B. Davis, Songhu Wang, Matias Jones +46
We report the discovery and confirmation of two new hot Jupiters discovered by the Transiting Exoplanet Survey Satellite (TESS): TOI 564 b and TOI 905 b. The transits of these two…
X-ray spectral and flux variability of the microquasar GRS 1758-258 on timescales from weeks to years
Maria Hirsch, Katja Pottschmidt, David M. Smith +12
We present the spectral and timing evolution of the persistent black hole X-ray binary GRS 1758-258 based on almost 12 years of observations using the Rossi X-ray Timing Explorer P…
OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf
Shota Miyazaki, Takahiro Sumi, David P. Bennett +92
We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…
Revealing The CO X-factor In Dark Molecular Gas through Sensitive ALMA Absorption Observations
Gan Luo, Di Li, Ningyu Tang +11
Carbon-bearing molecules, particularly CO, have been widely used as tracers of molecular gas in the interstellar medium (ISM). In this work, we aim to study the properties of molec…
Machine Learning Regression of extinction in the second Data Release
Yu Bai, JiFeng Liu, YiLun Wang +1
Machine learning has become a popular tool to help us make better decisions and predictions, based on experiences, observations and analysing patterns within a given data set witho…
The GBT Diffuse Ionized Gas Survey: Tracing the Diffuse Ionized Gas around the Giant HII Region W43
Matteo Luisi, L. D. Anderson, Bin Liu +4
The Green Bank Telescope (GBT) Diffuse Ionized Gas Survey (GDIGS) is a fully-sampled radio recombination line (RRL) survey of the inner Galaxy at C-band (4-8 GHz). We average toget…
Lithium-rich Giants in LAMOST Survey. I. The Catalog
Qi Gao, Jian-Rong Shi, Hong-Liang Yan +5
Standard stellar evolution model predicts a severe depletion of lithium (Li) abundance during the first dredge up process (FDU). Yet a small fraction of giant stars are still found…
Flash ionization signatures in the type Ibn supernova SN 2019uo
Anjasha Gangopadhyay, Kuntal Misra, Daichi Hiramatsu +26
We present photometric and spectroscopic observations of the type Ibn supernova (SN) 2019uo, the second ever SN Ibn with flash ionization (He II, C III, N III) features in its earl…
Triggering mechanism and material transfer of a failed solar filament eruption
X. L. Yan, Z. K. Xue, X. Cheng +6
Soar filament eruptions are often associated with solar flares and coronal mass ejections (CMEs), which are the major impacts on space weather. However, the fine structures and the…
Probing black hole accretion tracks, scaling relations and radiative efficiencies from stacked X-ray active galactic nuclei
Francesco Shankar, David H. Weinberg, Christopher Marsden +25
The masses of supermassive black holes at the centres of local galaxies appear to be tightly correlated with the mass and velocity dispersions of their galactic hosts. However, the…
Cosmological constraints on ultra-light axion fields
Jiangang Kang, Yan Gong, Gong Cheng +1
Ultra-light axions (ULAs) with mass less than 10^-20 eV have interesting behaviors that may contribute to either dark energy or dark matter at different epochs of the Universe. Its…
