Galaxy clustering and galaxy bias in a Lambda CDM universe
formation large-scale structure of universe
2014/12/24
We investigate galaxy clustering and the correlations between galaxies and mass in the ΛCDM cosmological model (inflationary cold dark matter with Ωm = 0.4, ΩΛ = 0.6, h = 0.65, n = 0.95, and σ8 = 0.8)...
Galaxies in a simulated Lambda CDM Universe - I. Cold mode and hot cores
cooling fl ows feedback cluster
2014/12/23
We study the formation of galaxies in a large volume (50 h−1 Mpc, 2 × 2883 particles) cosmological simulation, evolved using the entropy and energy-conserving smoothed particle hydrodynamics (SP...
Galaxies in a simulated Lambda CDM universe - II. Observable properties and constraints on feedback
feedback cluster
2014/12/23
We compare the properties of galaxies that form in a cosmological simulation without strong feedback to observations of the z= 0 galaxy population. We confirm previous findings that models without str...
Collapse thresholds for the formation of CDM haloes in the ellipsoidal collapse model
cosmology: dark matter – methods: numerical
2011/10/20
In the excursion set approach to structure formation initially spherical regions of the linear density field collapse if the average density contrast within them exceeds some critical value, \delta_c....
The ATLAS3D Project-- VIII: Modelling the Formation and Evolution of Fast and Slow Rotator Early-Type Galaxies within $Λ$CDM
galaxies elliptical and lenticular cD – galaxies formation – galaxies evolution – galaxies structure
2011/10/21
We propose a simple model for the origin of fast and slow rotator early-type galaxies (ETG) within the hierarchical $\Lambda$CDM scenario, that is based on the assumption that the mass fraction of ste...
Redshift and distances in a ΛCDM cosmology with non-linear inhomogeneities
cosmology: theory, relativity, large-scale structure of Universe, super- novae: general
2011/10/13
In this paper we study the effects of inhomogeneities on light propagation in a flat {\Lambda}CDM background. To this end we use exact solutions of Einstein's equations (Meures & Bruni 2011) where, st...
Dynamical neutrino masses in the generalized Chaplygin gas scenario with mass varying CDM

2010/11/10
Neutrinos coupled to an underlying scalar field in the scenario for unification of mass varying
dark matter and cosmon-like dark energy is examined. In the presence of a tiny component of mass varyin...
An exact cosmological solution of a Scalar-Tensor Gravity theory compatible with the $\Lambda$CDM model
exact cosmological solution Scalar-Tensor Gravity theory compatible $\Lambda$CDM model
2010/11/15
consider the massive Scalar-Tensor theory in the Jordan frame F() = K22,Z() = 1, and U() = (1/2)m22, F() corresponds to a constant Brans-Dicke parameter !BD = 1/4K2. The constaint of the solar s...

不同方案下中国CDM的成本－效益分析：基于CGE的实证模拟
CDM 成本-效益分析 减排方案 中国CDM政策
2008/7/6
中国CO2减排进行成本-效益的经济影响分析是有意义的。首先，提出国家层次和部门层次CO2减排成本和效益的概念及计算方法；第二，提出4种减排方案（经济-技术进步、能源结构改善、SO2排放控制与碳税），并就减排成本、效益与减排的总经济影响进行了减排方案与正常排放（BAU）方案的比较，以及减排方案之间的比较；第三，根据上述结果，对中国CDM项目的规划、设置、谈判和实施提出建议。
Strong Limits on the Possible Decay of the Vacuum Energy into CDM or CMB Photons
the Vacuum Energy CDM CMB Photons
2010/10/18
We investigate models that suggest that the vacuum energy could decay into cold dark matter (CDM) or into a homogeneous distribution of thermalized cosmic microwave background (CMB) photons. We show t...
