Abstract We review the observational foundations of the Λ CDM model, considered by most cosmologists as the standard model of cosmology. The Cosmological Principle, a key assumption of the model is shown to be verified with increasing accuracy. The fact that the Universe seems to have expanded from a hot and dense past is supported by many independent probes (galaxy redshifts, Cosmic Microwave Background, Big-Bang Nucleosynthesis and reionization). The explosion of detailed observations in the… Expand
The Intrinsic Bispectrum of the Cosmic Microwave Background
Cosmology, intended as the study of the origin and evolution of the Universe and its components, has advanced from being a philosophical discipline to a data-driven science. Much of this progress wasExpand
The Standard Model of Cosmology
Cosmologists are now converging towards a unified picture of the Universe, similar to when particle physicists built the standard model of particle physics. The standard model of cosmology depictsExpand
Large Scale Cosmological Anomalies and Inhomogeneous Dark Energy
A wide range of large scale observations hint towards possible modifications on the standard cosmological model which is based on a homogeneous and isotropic universe with a small cosmologicalExpand
On the interpretive role of theories of gravity and ‘ugly’ solutions to the total evidence for dark matter
Abstract Peter Kosso (2013) discusses the weak gravitational lensing observations of the Bullet Cluster and argues that dark matter can be detected in this system solely through the equivalenceExpand
Exploring cosmic homogeneity with the BOSS DR12 galaxy sample
In this study, we probe the transition to cosmic homogeneity in the Large Scale Structure (LSS) of the Universe using the CMASS galaxy sample of BOSS spectroscopic survey which covers the largestExpand
On the philosophy of cosmology
This paper gives an overview of significant issues in the philosophy of cosmology, starting off by emphasizing the uniqueness of the universe and the way models are used in description andExpand
A mysterious Universe: Revealing the bright and dark sides of the cosmos
Why is our universe as we observe it? Will it be the same forever? Understanding the nature of the main constituents of the universe is crucial to obtain a precise description of the way in which itExpand
Analysis of repulsive central universal force field on solar and galactic dynamics
Abstract Recent astrophysical observations hint toward the need for an extended theory of gravity to explain puzzles presented by the standard cosmological model such as the need for dark matter andExpand
Asymptotic solution for expanding universe with matter-dominated evolution
We applied the theory of regularly varying functions to the analysis of the cosmological parameters for the $\Lambda$CDM model with the matter dominated evolution. Carroll et al. proved in 1992 thatExpand
In this study, we probe the cosmic homogeneity with the BOSS CMASS galaxy sample in the redshift region of $0.43 < z < 0.7$. We use the normalised counts-in-spheres estimator $\mathcal{N}(<r)$ andExpand


Observational probes of cosmic acceleration
The accelerating expansion of the universe is the most surprising cosmological discovery in many decades, implying that the universe is dominated by some form of “dark energy” with exotic physicalExpand
The cosmological constant and cold dark matter
THE cold dark matter (CDM) model1–4 for the formation and distribution of galaxies in a universe with exactly the critical density is theoretically appealing and has proved to be durable, but recentExpand
Reconciling the local void with the CMB
In the standard cosmological model, the dimming of distant Type Ia supernovae is explained by invoking the existence of repulsive ''dark energy'' which is causing the Hubble expansion to accelerate.Expand
Signals from the epoch of cosmological recombination – Karl Schwarzschild Award Lecture 2008
The physical ingredients to describe the epoch of cosmological recombination are amazingly simple and well-understood. This fact allows us to take into account a very large variety of physicalExpand

It is confirmed that the vanishing of the dipole, quadrupole and octupole of the CMB is sufficient to impose homogeneity, and observations of the cosmic microwave background, galaxies and clusters are used to test homogeneity itself. Expand
Detection of polarization in the cosmic microwave background using DASI
The detection of polarization of the CMB with the Degree Angular Scale Interferometer (DASI) is reported, and its level and spatial distribution are in excellent agreement with the predictions of the standard theory. Expand
Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant
We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 " z " 0.62. The luminosity distances of these objects are determined by methods thatExpand
The removal of cusps from galaxy centres by stellar feedback in the early Universe
Numerical simulations show that random bulk motions of gas in small primordial galaxies will result in a flattening of the central dark matter cusp on relatively short timescales (∼108 years), which would have operated in all star-forming galaxies at redshifts z ≥ 10. Expand
The Evolution of the Universe
It is concluded first of all that the relative abundances of various atomic species must represent the most ancient archæological document pertaining to the history of the universe, and that it must have been established during the earliest stages of expansion. Expand
Kinematical and Chemical Vertical Structure of the Galactic Thick Disk. II. A Lack of Dark Matter in the Solar Neighborhood
We estimated the dynamical surface mass density Σ at the solar position between Z = 1.5 and 4 kpc from the Galactic plane, as inferred from the kinematics of thick disk stars. The formulation isExpand
