Star formation and gas in the minor merger UGC 10214
D. Rosado-Belza, U. Lisenfeld, J. Hibbard +6
UGC 10214 is a minor merger in which a dwarf galaxy has interacted with a large spiral galaxy 250 Myr ago and produced a perturbed disk and a giant tidal tail. We use a multi…
Chemical and kinematic analysis of CN-strong Metal-poor Field Stars in LAMOST DR3
Baitian Tang, Chao Liu, J. G. Fernandez-Trincado +5
The large amount of chemical and kinematic information available in large spectroscopic surveys have inspired the search for chemically peculiar stars in the field. Though these me…
Ionization Profiles of Galactic HII Regions

Using Green Bank Telescope radio recombination line (RRL) data, we analyze the role of leaking radiation from HII regions in maintaining the ionization of the interstellar medium.…
Orbit properties of massive prolate galaxies in the Illustris simulation
Yougang Wang, Shude Mao, Hongyu Li +3
We explore orbit properties of 35 prolate-triaxial galaxies selected from the Illustris cosmological hydrodynamic simulation. We present a detailed study of their orbit families, a…
The origin of high velocity stars from Gaia and LAMOST
Cuihua Du, Hefan Li, Heidi Jo Newberg +4
Based on the second Gaia data (Gaia DR2) and spectroscopy from the LAMOST Data Release 5, we defined the high-velocity (HiVel) stars sample as those stars with $v_{\mathrm{gc}} > 0…
On the absence of dark matter in dwarf galaxies surrounding the Milky Way
Francois Hammer, Yanbin Yang, Jianling Wang +3
This paper presents an alternative scenario to explain the observed properties of the Milky Way dwarf Spheroidals (MW dSphs). We show that instead of resulting from large amounts o…
Polarimetric and photometric investigation of a dark globule LDN 1225: distance, extinction law, and magnetic fields
Chakali Eswaraiah, Shih-Ping Lai, Yuehui Ma +7
We present the results based on the optical -band polarization observations of 280 stars distributed towards the dark globule LDN\,1225. {\it Gaia} data release 2 parallaxes alo…
A Machine Learning Based Morphological Classification of 14,245 Radio AGNs Selected From The Best-Heckman Sample
Zhixian Ma, Haiguang Xu, Jie Zhu +8
We present a morphological classification of 14,245 radio active galactic nuclei (AGNs) into six types, i.e., typical Fanaroff--Riley Class I / II (FRI/II), FRI/II-like bent-tailed…
JCMT BISTRO survey: Magnetic Fields within the Hub-Filament Structure in IC 5146
Jia-Wei Wang, Shih-Ping Lai, Chakali Eswaraiah +130
We present the 850 m polarization observations toward the IC5146 filamentary cloud taken using the Submillimetre Common-User Bolometer Array 2 (SCUBA-2) and its associated polar…
Comparing galaxy morphology in hydrodynamical simulation and in semi-analytic model
Lan Wang, Dandan Xu, Liang Gao +3
We compare galaxy morphology predicted by the Illustris hydrodynamical simulation and a semi-analytic model (SAM) grafted in the halo merger trees from the Illustris-Dark matter si…
The Origins of Young Stars in the Direction of the Leading Arm of the Magellanic Stream: Abundances, Kinematics, and Orbits
Lan Zhang, Dana I. Casetti-Dinescu, Christian Moni Bidin +6
We explore the origins of the young B-type stars found by Casetti-Dinescu et al.(2014) at the outskirts of the Milky-Way disk in the sky region of Leading Arm of the Magellanic Str…
The spiral structure of the Milky Way
Ye Xu, Ligang Hou, Yuanwei Wu
The morphology and kinematics of the spiral structure of the Milky Way is a long-standing problem in astrophysics. In this review we firstly summarize various methods with differen…
The Environments of Luminous Radio - WISE Selected Infrared Galaxies
J. I. Penney, A. W. Blain, D. Wylezalek +17
We have observed the environments of a population of 33 heavily dust obscured, ultra-luminous, high-redshift galaxies, selected using WISE and NVSS at 1.3 with the Infra-Red Ar…
GD-1: the relic of an old metal-poor globular cluster
Guang-Wei Li, Brian Yanny, Yue Wu
Combining data from Gaia DR2, SDSS DR14 and LAMOST DR6, we update the fit to model of the properties of the stellar stream GD-1 and find that it has an age of Gyr, [Fe/H]…
