A mapping study of L1174 with 13CO J=2-1 and 12CO J=3-2: star formation triggered by a Herbig Ae/Be star
J. H. Yuan, Y. Wu, J. Z. Li +2
We have carried out a comprehensive study of the molecular conditions and star-forming activities in dark cloud L1174 with multi-wavelength data. Mapping observations of L1174 in $…
The Origem Loop
X. Y. Gao, J. L. Han
The Origem Loop in the Galactic anticentre was discovered in 1970s and suggested to be a large supernova remnant. It was argued later to be a chance superposition of unrelated radi…
Magnetic fields in our Milky Way Galaxy and nearby galaxies
JinLin Han
Magnetic fields in our Galaxy and nearby galaxies have been revealed by starlight polarization, polarized emission from dust grains and clouds at millimeter and submillimeter wavel…
A Metal-Strong and Dust-Rich Damped \lya Absorption System toward the Quasar SDSS J115705.52+615521.7
Jian-Guo Wang, Hong-Yan Zhou, Jian Ge +7
(Abridged for arXiv) We report the discovery of an unusual, extremely dust-rich and metal-strong damped \lya absorption system (DLA) at a redshift toward the quasar…
The SEGUE K giant survey II: A Catalog of Distance Determinations for the SEGUE K giants in the Galactic Halo
Xiang-Xiang Xue, Zhibo Ma, Hans-Walter Rix +13
We present an online catalog of distance determinations for K giants, most of which are members of the Milky Way's stellar halo. Their medium-resolution spectra from SDS…
Pulsars as excellent probes for the magnetic structure in our Milky Way
JinLin Han
In this invited talk, I first discuss the advantages and disadvantages of many probes for the magnetic fields of the Milky Way. I conclude that pulsars are the best probes for the…
Made-to-measure galaxy models - III Modelling with Milky Way observations
R. J. Long, Shude Mao, Juntai Shen +1
We demonstrate how the Syer & Tremaine made-to-measure method of stellar dynamical modelling can be adapted to model a rotating galactic bar. We validate our made-to-measure change…
Metallicity Gradients of Thick Disk Dwarf Stars
Kenneth Carrell, Yuqin Chen, Gang Zhao
We examine the metallicity distribution of the Galactic thick disk using F, G, and K dwarf stars selected from the Sloan Digital Sky Survey, Data Release 8. Using the large sample…
S-stars in the Galactic center and hypervelocity stars in the Galactic halo: two faces of the tidal breakup of stellar binaries by the central massive black hole?
Fupeng Zhang, Youjun Lu, Qingjuan Yu
In this paper, we investigate the link between the hypervelocity stars (HVSs) discovered in the Galactic halo and the S-stars moving in the Galactic center (GC), under the hypothes…
Does the dwarf galaxy system of the Milky Way originate from Andromeda?
Sylvain Fouquet, François Hammer, Yanbin Yang +2
The Local Group is often seen to be a quiescent environment without significant merger events. However an ancient major merger may have occurred in the most massive galaxy. Numeric…
Triggered Star Formation from Bubbles S51, N68, and N131
Chuan-Peng Zhang, Jun-Jie Wang
We investigated the environment of the infrared dust bubbles S51, N68, and N131 from catalogue of Churchwell et al. (2006), and searched for evidence of triggered star formation.
Determining neutron star masses with weak microlensing
Lanlan Tian, Shude Mao
The masses of stars including stellar remnants are almost exclusively known from binary systems. In this work, we study gravitational microlensing of faint background galaxies by i…
A New Model for the Milky Way Bar
Yougang Wang, Hongsheng Zhao, Shude Mao +1
We use Schwarzschild's orbit-superposition technique to construct self-consistent models of the Galactic bar. Using minimisation, we find that the best-fit Galactic bar model…
The Gravitational Potential Near the Sun From SEGUE K-dwarf Kinematics
Lan Zhang, Hans-Walter Rix, Glenn van de Ven +3
To constrain the Galactic gravitational potential near the Sun (1.5 kpc), we derive and model the spatial and velocity distribution for a sample of 9000 K-dwarfs that have sp…
Modes of clustered star formation
S. Pfalzner, T. Kaczmarek, C. Olczak
The realization that most stars form in clusters, raises the question of whether star/planet formation are influenced by the cluster environment. The stellar density in the most pr…
Star formation associated with the infrared dust bubble N68
Chuan-Peng Zhang, Jun-Jie Wang
We investigated the environment of the infrared dust bubble N68 and searched for evidence of triggered star formation in its surroundings. We performed a multiwavelength study of t…
A new determination of the local dark matter density from the kinematics of K dwarfs
Silvia Garbari, Chao Liu, Justin I. Read +1
We apply a new method to determine the local disc matter and dark halo matter density to kinematic and position data for \sim2000 K dwarf stars taken from the literature. Our metho…
Radio perspectives on the Monoceros SNR G205.5+0.5
L. Xiao, M. Zhu
The Monoceros Loop (SNR G205.5+0.5) is a large shell-type supernova remnant located in the Rosette Complex region. It was suggested to be interacting with the Rosette Nebula. We ai…
Detailed comparison of Milky Way models based on stellar population synthesis and SDSS star counts at the north Galactic pole
Shuang Gao, Andreas Just, Eva K. Grebel
We test the ability of the TRILEGAL and Besancon models to reproduce the CMD of SDSS data at the north Galactic pole (NGP). We show that a Hess diagram analysis of colour-magnitude…
Astrophysical Applications of Gravitational Microlensing
Shude Mao
Since the first discovery of microlensing events nearly two decades ago, gravitational microlensing has accumulated tens of TBytes of data and developed into a powerful astrophysic…
