Outflows from active galactic nuclei: The BLR-NLR metallicity correlation
Pu Du, Jian-Min Wang, Chen Hu +4
The metallicity of active galactic nuclei (AGNs), which can be measured by emission line ratios in their broad and narrow line regions (BLRs and NLRs), provides invaluable informat…
A statistical study of gaseous environment of Spitzer interstellar bubbles
L. G. Hou, X. Y. Gao
The expansion of interstellar bubbles is suggested to be an important mechanism of triggering material accumulation and star formation. In this work, we study the gaseous environme…
GSH 90-28-17: a Possible Old Supernova Remnant
L. Xiao, M. Zhu
GSH 90-28-17 is a high-latitude galactic HI supershell, identified in the HI supershell catalogs with a velocity of \kms. We used the new Arecibo GALFA-HI survey d…
The Link Between Ejected Stars, Hardening and Eccentricity Growth of Super Massive Black Holes in Galactic Nuclei
Long Wang, Peter Berczik, Rainer Spurzem +1
The hierarchical galaxy formation picture suggests that super massive black holes (MBHs) observed in galactic nuclei today have grown from coalescence of massive black hole binarie…
A Sino-German 6cm polarisation survey of the Galactic plane - VIII. Small-diameter sources
W. Reich, X. H. Sun, P. Reich +3
Information of small-diameter sources is extracted from the Sino-German 6cm polarisation survey of the Galactic plane carried out with the Urumqi 25-m telescope. We performed two-d…
Three-dimensional Microlensing
Shude Mao, Hans J. Witt, Jin H. An
We study three-dimensional microlensing where two lenses are located at different distances along the line of sight. We formulate the lens equation in complex notations and recover…
Triggered massive and clustered stars formation by together H II regions G38.91-0.44 and G39.30-1.04
Jin-Long Xu, Jun-Jie Wang, Xiao-Lan Liu
We present the radio continuum, infrared, and CO molecular observations of infrared dark cloud (IRDC) G38.95-0.47 and its adjacent H II regions G38.91-0.44 (N74), G38.93-0.39 (N75)…
Stochastic stellar cluster IMFs: Models and impact on integrated cluster parameter determination
P. Anders, R. Kotulla, R. de Grijs +1
Stellar clusters are regularly used to study the evolution of their host galaxy. Except for a few nearby galaxies, these studies rely on the interpretation of integrated cluster pr…
Exploring the total Galactic extinction with SDSS BHB stars
Hai-Jun Tian, Chao Liu, Jing-Yao Hu +2
Aims: We used 12,530 photometrically-selected blue horizontal branch (BHB) stars from the Sloan Digital Sky Survey (SDSS) to estimate the total extinction of the Milky Way at the h…
Substructure in bulk velocities of Milky Way disk stars
Jeffrey L. Carlin, James DeLaunay, Heidi Jo Newberg +11
We find that Galactic disk stars near the anticenter exhibit velocity asymmetries in both the Galactocentric radial and vertical components across the mid-plane as well as azimutha…
Thermal and non-thermal emission in the Cygnus X region
W. F. Xu, X. Y. Gao, J. L. Han +1
Radio continuum observations detect non-thermal synchrotron and thermal bremsstrahlung radiation. Separation of the two different emission components is crucial to study the proper…
When is an axisymmetric potential separable?
J. An
An axially symmetric potential psi(R,z)=psi(r,theta) is completely separable if the ratio s:k is constant. Here r*s=d^2(r^2*psi)/dr/d(theta) and k=d^2(psi)/dR/dz. If beta=s/k, then…
The James Clerk Maxwell Telescope Nearby Galaxies Legacy Survey IX: CO Observations of NGC 2976 and NGC 3351
Boon-Kok Tan, J. Leech, D. Rigopoulou +20
We present CO \textit{J=32} maps of NGC 2976 and NGC 3351 obtained with the James Clerk Maxwell Telescope (JCMT), both early targets of the JCMT Nearby Galaxy L…
No compelling evidence of significant early star cluster disruption in the Large Magellanic Cloud
Richard de Grijs, Simon P. Goodwin, Peter Anders
Whether or not the rich star cluster population in the Large Magellanic Cloud (LMC) is affected by significant disruption during the first few x 10^8 yr of its evolution is an open…
A Schwarzschild model of the Galactic bar with initial density from N-body simulations
Yougang Wang, Shude Mao, Richard J. Long +1
Using the potential from N-body simulations, we construct the Galactic bar models with the Schwarzschild method. By varying the pattern speed and the position angle of the bar, we…
SIGGMA: A Survey of Ionized Gas in the Galaxy, Made with the Arecibo Telescope
B. Liu, T. Mclntyre, Y. Terzian +5
A Survey of Ionized Gas in the Galaxy, made with the Arecibo telescope (SIGGMA) uses the Arecibo L-band Feed Array (ALFA) to fully sample the Galactic plane (30 < l < 75 and -2 < b…
Numerical Simulation of a possible origin of the positive radial metallicity gradient of the thick disk
Awat Rahimi, Kenneth Carrell, Daisuke Kawata
We analyze the radial and vertical metallicity and [alpha/Fe] gradients of the disk stars of a disk galaxy simulated in a fully cosmological setting with the chemodynamical galaxy…
