Large Size Scatter of Passively Evolving Lensed Galaxies at z~2 in CLASH
Lulu Fan, Yang Chen, Xinzhong Er +3
In a systematic search over 11 cluster fields from Cluster Lensing And Supernova survey with Hubble (CLASH) we identify ten passively evolving massive galaxies at redshift z~2.We d…
The Tianlai project: a 21cm cosmology experiment
Xuelei Chen
In my talk at the 2nd Galileo-Xu Meeting, I presented several different topics in 21cm cosmology for which I have done research. These includes the 21cm signature of the first star…
Semi-Numerical Simulation of Reionization with Semi-Analytical Modeling of Galaxy Formation
Jie Zhou, Qi Guo, Gaochao Liu +3
In a semi-numerical model of reionization, the evolution of ionization fraction is simulated approximately by the ionizing photon to baryon ratio criterion. In this paper we incorp…
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 $…
Seven-Year Multi-Color Optical Monitoring of BL Lacertae Object S5 0716+714
Yan Dai, Jianghua Wu, Zong-Hong Zhu +4
We have monitored the BL Lac object S5 0716+714 in five intermediate optical wavebands from 2004 September to 2011 April. Here we present the data that include 8661 measurements wh…
Gravitational lensing properties of isothermal universal halo profile
Xinzhong Er
N-body simulations predict that dark matter halos with different mass scales are described by a universal model, the Navarro-Frenk-White (NFW) density profiles. As a consequence of…
Delayed Onset and Fast Rise of Prompt Optical-UV Emission from Gamma-Ray Bursts in Molecular Clouds
Xiao-Hong Cui, Zhuo Li, Li-Ping Xin
Observations imply that long γ-ray bursts (GRBs) are originated from explosions of massive stars, therefore they may occur in the molecular clouds where their progenitors were born…
Effects of tidally enhanced stellar wind on the horizontal branch morphology of globular clusters
Zhen-Xin Lei, Xue-Fei Chen, Feng-Hui Zhang +1
Metallicity is the first parameter to influence the horizontal branch (HB) morphology of globular clusters (GCs). It has been found, however, that some other parameters may also pl…
The 2MASS Tully-Fisher Survey : Mapping the Mass in the Universe
T. Hong, L. Staveley-Smith, K. Masters +5
The 2MASS Tully-Fisher Survey (2MTF) aims to measure Tully-Fisher (TF) distances for all bright inclined spirals in the 2MASS Redshift Survey (2MRS) using high quality HI widths an…
A Model for the Correlation of Hard X-ray Index with Eddington Ratio in Black Hole X-ray Binaries
ErLin Qiao, B. F. Liu
Observations show that there is a positive correlation between Eddington ratio and hard X-ray index for , and there is an anti-correlation between and $Γ…
Simulations of the galaxy population constrained by observations from z=3 to the present day: implications for galactic winds and the fate of their ejecta
Bruno Henriques, Simon White, Peter Thomas +4
We apply Monte Carlo Markov Chain (MCMC) methods to large-scale simulations of galaxy formation in a LambdaCDM cosmology in order to explore how star formation and feedback are con…
Current helicity constraints in solar dynamo models
D. Sokoloff, H. Zhang, D. Moss +5
We investigate to what extent the current helicity distribution observed in solar active regions is compatible with solar dynamo models. We use an advanced 2D mean-field dynamo mod…
Sequential clustering of star formation in IC 1396
Ya Fang Huang, Jin Zeng Li
We present in this paper a comprehensive study of the H II region IC 1396 and its star formation activity, in which multi-wavelength data ranging from the optical to the near- and…
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…
Multi-Wavelength Study of a Complete IRAC 3.6micron-Selected Galaxy Sample: a Fair Census of Red and Blue Populations at Redshifts 0.4-1
J. -S. Huang, S. M. Faber, C. N. A. Willmer +14
We present a multi-wavelength study of a 3.6 m-selected galaxy sample in the Extended Groth strip. The sample is complete for galaxies with stellar mass \Msun and re…
Rossby Wave Instability in Accretion Discs with Large-Scale Poloidal Magnetic Fields
Cong Yu, Dong Lai
We study the effect of large-scale magnetic fields on the non-axisymmetric Rossby wave instability (RWI) in accretion discs. The instability develops around a density bump, which i…
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 generic method to constrain the dark matter model parameters from Fermi observations of dwarf spheroids
Yue-Lin Sming Tsai, Qiang Yuan, Xiaoyuan Huang
Observation of gamma-rays from dwarf galaxies is an effective way to search for particle dark matter. Using 4-year data of Fermi-LAT observations on a series of Milky Way satellite…
