High-z Quasars in the R_h=ct Universe
Fulvio Melia
One cannot understand the early appearance of 10^9 solar-mass black holes without invoking anomalously high accretion rates or the creation of exotically massive seeds, neither of…
A Study on the Chemical Properties of Blue Compact Dwarf Galaxies
Yinghe Zhao, Yu Gao, Qiusheng Gu
In this paper, we report our studies on the gaseous and chemical properties of a relatively large sample (53 members) of blue compact dwarf galaxies (BCDs). The results of correlat…
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…
The dependence of tidal stripping efficiency on the satellite and host galaxy morphology
Jiang Chang, Andrea V. Maccio', Xi Kang
In this paper we study the tidal stripping process for satellite galaxies orbiting around a massive host galaxy, and focus on its dependence on the morphology of both satellite and…
Evidence for CO shock excitation in NGC 6240 from Herschel SPIRE spectroscopy
R. Meijerink, L. E. Kristensen, A. Weiss +28
We present Herschel SPIRE FTS spectroscopy of the nearby luminous infrared galaxy NGC 6240. In total 20 lines are detected, including CO J=4-3 through J=13-12, 6 H2O rotational lin…
Correlation between Line Width and Line Flux of Double-Peaked Broad Halpha of 3C390.3
XueGuang Zhang
In this manuscript, we carefully check the correlation between the line width and the line flux of the double-peaked broad H of the well-known mapped AGN 3C390.3, in order to sh…
AGN host galaxies at redshift z~0.7: peculiar or not?
Asmus Boehm, Lutz Wisotzki, Eric F. Bell +21
We perform a quantitative morphological comparison between the hosts of Active Galactic Nuclei (AGN) and quiescent galaxies at intermediate redshifts (z~0.7). The imaging data are…
Constraining dark energy using observational growth rate data
K. Shi, Y. F. Huang, T. Lu
Observational growth rate data had been derived from observations of redshift distortions in galaxy redshift surveys. Here we use the growth rate data to place constraints on the d…
The Stellar and Gas Kinematics of the LITTLE THINGS Dwarf Irregular Galaxy NGC 1569
Megan Johnson, Deidre A. Hunter, Se-Heon Oh +5
In order to understand the formation and evolution of dIm galaxies, one needs to understand their three-dimensional structure. We present measurements of the stellar velocity dispe…
The effect of Warm Dark Matter on galaxy properties: constraints from the stellar mass function and the Tully-Fisher relation
Xi Kang, Andrea V. Macciò, Aaron A. Dutton
In this paper we combine high resolution N-body simulations with a semi analytical model of galaxy formation to study the effects of a possible Warm Dark Matter (WDM) component on…
A comprehensive comparison of cosmological models from latest observational data
Ke Shi, Yongfeng Huang, Tan Lu
We investigate in detail some popular cosmological models in light of the latest observational data, including the Union2.1 supernovae compilation, the baryon acoustic oscillation…
Statistical interpretation of the spatial distribution of current 130 GeV gamma-ray line signal within the dark matter annihilation scenario
Rui-Zhi Yang, Qiang Yuan, Lei Feng +2
Recently, several groups identified a tentative -ray line signal with energy GeV in the central Galaxy from the Fermi-LAT data. %The morphology study shows that the s…
Bulk flow of halos in ΛCDM simulation
Ming Li, Jun Pan, Liang Gao +10
Analysis of the Pangu N-body simulation validates that the bulk flow of halos follows a Maxwellian distribution which variance is consistent with the prediction of the linear theor…
Peculiar Velocity Decomposition, Redshift Space Distortion and Velocity Reconstruction in Redshift Surveys - I. The Methodology
Pengjie Zhang, Jun Pan, Yi Zheng
Massive spectroscopic surveys will measure the redshift space distortion (RSD) induced by galaxy peculiar velocity to unprecedented accuracy. We develop a new method to improve the…
The Dynamical State and Mass-Concentration Relation of Galaxy Clusters
Aaron D. Ludlow, Julio F. Navarro, Ming Li +3
We use the Millennium Simulation series to study how the dynamical state of dark matter halos affects the relation between mass and concentration. We find that a large fraction of…
Influence of baryons on spatial distribution of matter: higher order correlation functions
Xiaojun Zhu, Jun Pan
Baryonic physical processes could leave non-negligible imprint on cosmic matter distribution pattern. Series of high precision simulation data sets with identical initial condition…
