The nature of red dwarf galaxies
Yu Wang, Xiaohu Yang, H. J. Mo +5
Using dark matter halos traced by galaxy groups selected from the Sloan Digital Sky Survey Data Release 4, we find that about 1/4 of the faint galaxies ($\rmag >-17.05$, hereafter…
The Gravitational Shear--Intrinsic Ellipticity Correlation Functions of Luminous Red Galaxies in Observation and in the CDM Model
Teppei Okumura, Y. P. Jing
We examine whether the gravitational shear--intrinsic ellipticity (GI) correlation function of the luminous red galaxies (LRGs) can be modeled with the distribution function of a m…
An accretion disc-corona model for X-ray spectra of active galactic nuclei
Xinwu Cao
The hard X-ray emission of active galactic nuclei (AGN) is believed to originate from the hot coronae above the cold accretion discs. The hard X-ray spectral index is found to be c…
Modeling Nonlinear Evolution of Baryon Acoustic Oscillations: Convergence Regime of N-body Simulations and Analytic Models
Takahiro Nishimichi, Akihito Shirata, Atsushi Taruya +10
We use a series of cosmological N-body simulations and various analytic models to study the evolution of the matter power spectrum in real space in a ΛCold Dark Matter universe. We…
The Apparent "Angular Size - Frequency" Dependence in ~3000 Parsec-scale Extragalactic Jets
J. Yang, L. I. Gurvits, S. Frey +1
The upper envelope of the amplitude of the VLBI visibility function usually represents the most compact structural pattern of extragalactic radio sources, in particular, the "core-…
A Modified Stratified Model for 3C 273 Jet
Wen-Po Liu, Zhi-Qiang Shen
We present a modified stratified jet model to interpret the observed spectral energy distributions of knots in 3C 273 jet. Based on the hypothesis of the single index of the partic…
Trigonometric Parallaxes of Massive Star Forming Regions: IV. G35.20-0.74 and G35.20-1.74
B. Zhang, X. W. Zheng, M. J. Reid +4
We report trigonometric parallaxes for the high-mass star forming regions G35.20-0.74 and G35.20-1.74, corresponding to distances of 2.19 (+0.24 -0.20) kpc and 3.27 (+0.56 -0.42) k…
The distribution of ejected subhalos and its implication for halo assembly bias
Huiyuan Wang, H. J. Mo, Y. P. Jing
Using a high-resolution cosmological -body simulation, we identify the ejected population of subhalos, which are halos at redshift but were once contained in more massive…
A Magnetohydrodynamic Model for the Formation of Episodic Jets
Feng Yuan, Jun Lin, Kinwah Wu +1
Episodic ejection of plasma blobs have been observed in many black hole systems. While steady, continuous jets are believed to be associated with large-scale open magnetic fields,…
Alignment between galaxies and large-scale structure
A. Faltenbacher, Cheng Li, Simon D. M. White +3
Based on the Sloan Digital Sky Survey DR6 (SDSS) and Millennium Simulation (MS) we investigate the alignment between galaxies and large-scale structure. For this purpose we develop…
Accurate universal models for the mass accretion histories and concentrations of dark matter halos
D. H. Zhao, Y. P. Jing, H. J. Mo +1
A large amount of observations have constrained cosmological parameters and the initial density fluctuation spectrum to a very high accuracy. However, cosmological parameters chang…
Self calibration of gravitational shear-galaxy intrinsic ellipticity correlation in weak lensing surveys
Pengjie Zhang
The galaxy intrinsic alignment is a severe challenge to precision cosmic shear measurement. We propose to self-calibrate the induced gravitational shear-galaxy intrinsic ellipticit…
Self-Similar Solution of Hot Accretion Flows with Ordered Magnetic Field and Outflow
De-Fu Bu, Feng Yuan, Fu-Guo Xie
Observations and numerical magnetohydrodynamic (MHD) simulations indicate the existence of outflows and ordered large-scale magnetic fields in the inner region of hot accretion flo…
Alignments of Group Galaxies with Neighboring Groups
Yougang Wang, Changbom Park, Xiaohu Yang +2
Using a sample of galaxy groups found in the Sloan Digital Sky Survey Data Release 4, we measure the following four types of alignment signals: (1) the alignment between the distri…
The Correlation of Star Formation Quenching with Internal Galaxy Properties and Environment
Taysun Kimm, Rachel S. Somerville, Sukyoung K. Yi +8
We investigate the correlation of star formation quenching with internal galaxy properties and large scale environment (halo mass) in empirical data and theoretical models. We make…
Multi-frequency investigation of the parsec- and kilo-parsec-scale radio structures in high-redshift quasar PKS 1402+044
J. Yang, L. I. Gurvits, A. P. Lobanov +2
We investigate the frequency-dependent radio properties of the jet of the luminous high-redshift (z = 3.2) radio quasar PKS 1402+044 (J1405+0415) by means of radio interferometric…
Rapidly spinning massive black holes in active galactic nuclei: evidence from the black hole mass function
Xinwu Cao, Fan Li
The comparison of the black hole mass function (BHMF) of active galactic nuclei (AGN) relics with the measured mass function of the massive black holes in galaxies provides strong…
Origin of the X-ray Emission in the Nuclei of FR Is
Qingwen Wu, Feng Yuan, Xinwu Cao
We investigate the X-ray origin in FRIs using the multi-waveband high resolution data of eight FR I sources, which have very low Eddington ratios. We fit their multi-waveband spect…

A critical review of the evidence for M32 being a compact dwarf satellite of M31 rather than a more distant normal galaxy
C. K. S. Young, M. J. Currie, R. J. Dickens +2
Since Baade's photographic study of M32 in the mid 1940s, it has been accepted as an established fact that M32 is a compact dwarf satellite of M31. The purpose of this paper is to…
