Five E+A (post-starburst) galaxies as Brightest Cluster Galaxies
Feng-Shan Liu, Zhong-Lue Wen, Jin-Lin Han +1
Brightest Cluster Galaxies (BCGs) are mostly elliptical galaxies and very rarely have prominent star formation. We found that five out of 8,812 BCGs are E+A (i.e. post-starburst) g…
Tycho SN 1572: A Naked Ia Supernova Remnant without Associated Ambient Molecular Cloud
Wenwu Tian, Denis A. Leahy
The historical supernova remnant (SNR) Tycho SN 1572 originates from the explosion of a normal Type Ia supernova which is believed to have originated from a carbon-oxygen white dwa…
Estimation of absorption line indices of early-type galaxies using colours
Zhongmu LI, Ruheng LI, Ruxi LI
Context. Absorption line indices are widely used to determine the stellar population parameters such as age and metallicity of galaxies, but it is not easy to obtain the line indic…
A Sino-German 6 cm polarization survey of the Galactic plane III. The region from 10 degree to 60 degree longitude
X. H. Sun, W. Reich, J. L. Han +4
(Abridged) We have conducted a total intensity and polarization survey of the Galactic plane at 6 cm using the Urumqi 25 m telescope for the Galactic longitude range of 10 deg<l<60…
Color Behavior Of BL Lacertae Object OJ 287 During Optical Outburst
Yan Dai, Jianghua Wu, Zong-Hong Zhu +2
This paper aims to study the color behavior of the BL Lac object OJ 287 during optical outburst. According to the revisit of the data from the OJ-94 monitoring project and the anal…
Forming Protostars in Molecular Clouds with Shocked Envelope Expansion and Core Collapse
Yu-Qing Lou, Yang Gao
Spectral observations of molecular line profiles reveal the so-called `blue profiles' for double-peaked molecular lines with stronger blue and weaker red peaks as notable features…
Li - O anti-correlation in NGC 6752: evidence for Li-enriched polluting gas
Z. -X. Shen, P. Bonifacio, L. Pasquini +1
Elemental correlations and anti-correlations are known to be present in globular clusters (GCs) owing to pollution by CNO cycled gas. Because of its fragility Li is destroyed at th…
Quantifying Kinematic Substructure in the Milky Way's Stellar Halo
Xiang-Xiang Xue, Hans-Walter Rix, Brian Yanny +13
We present and analyze the positions, distances, and radial velocities for over 4000 blue horizontal-branch (BHB) stars in the Milky Way's halo, drawn from SDSS DR8. We search for…
The Galactic halo magnetic field revisited
Xiaohui Sun, Wolfgang Reich
Recently, Sun et al. (2008) published new Galactic 3D-models of magnetic fields in the disk and halo of the Milky Way and the distribution of cosmic-ray electron density by taking…
Does M31 result from an ancient major merger?
F. Hammer, Y. B. Yang, J. L. Wang +3
The numerous streams in the M31 halo are currently assumed to be due to multiple minor mergers. Here we use the GADGET2 simulation code to test whether M31 could have experienced a…
Could the Magellanic Clouds be tidal dwarves expelled from a past-merger event occurring in Andromeda?
Yanbin YANG, Francois HAMMER
The Magellanic Clouds are often considered as outliers in the satellite system of the Milky Way because they are irregular and gas-rich galaxies. From their large relative motion,…
The Prevalence of Narrow Optical Fe II Emission Lines in Type 1 Active Galactic Nuclei
Xiao-Bo Dong, Luis C. Ho, Jian-Guo Wang +4
From detailed spectral analysis of a large sample of low-redshift active galactic nuclei (AGNs) selected from the Sloan Digital Sky Survey, we demonstrate---statistically for the f…
Calibration of radii and masses of open clusters with a simulation
A. Ernst, A. Just, P. Berczik +1
Context: A recent new approach to apply a simple dynamical mass estimate of tidally limited star clusters is based on the identification of the tidal radius in a King profile with…
Compact Binaries in Star Clusters II - Escapers and Detection Rates
J. M. B. Downing, M. J. Benacquista, M. Giersz +1
We use a self-consistent Monte Carlo treatment of stellar dynamics to investigate black hole binaries that are dynamically ejected from globular clusters to determine if they will…
Photometric identification of blue horizontal branch stars
Kester W. Smith, Coryn A. L. Bailer-Jones, Rainer J. Klement +1
We investigate the performance of some common machine learning techniques in identifying BHB stars from photometric data. To train the machine learning algorithms, we use previousl…
Higher order moment models of dense stellar systems: Applications to the modeling of the stellar velocity distribution function
Justus Schneider, Pau Amaro-Seoane, Rainer Spurzem
Dense stellar systems such as globular clusters, galactic nuclei and nuclear star clusters are ideal loci to study stellar dynamics due to the very high densities reached, usually…
Radio sources with ultra-high polarization
H. Shi, H. Liang, J. L. Han +1
A sample of 129 unresolved radio sources with ultrahigh linear polarization (>30 per cent) has been selected from the NRAO VLA Sky Survey. Such high average linear polarization is…
The stellar content of the Hamburg/ESO survey VI. The metallicity distribution of main-sequence turnoff stars in the Galactic halo
H. N. Li, N. Christlieb, T. Schörck +7
We determine the metallicity distribution function (MDF) of the Galactic halo based on metal-poor main-sequence turnoff-stars (MSTO) which were selected from the Hamburg/ESO object…
Distribution of satellite galaxies in high redshift groups
Yougang Wang, Changbom Park, Ho Seong Hwang +1
We use galaxy groups at redshifts between 0.4 and 1.0 selected from the Great Observatories Origins Deep Survey (GOODS) to study the color-morphological properties of satellite gal…
