“…The search took place over a range of angular scales and at many frequencies. The interpretation paper, from Wright et al (1992), reports "The observed anisotropy is consistent with all previously measured upper limits and with a number of dynamical models of structure formation. There was a remarkable and steady advance that drove the development of new detector technologies: masers, heterodyne systems, bolometers, and new ways of observing the cosmos.…”

“…A joint analysis of the CfA/PPS power spectrum gave a best fit CDM shape parameter Γ = 0.34±0.1 [31]. Similarly, a joint analysis of the CfA/SSRS samples in [169] showed a power spectrum consistent with CDM models with Γ ≈ 0.2 and bias within 20% of unity when normalized to COBE [596,694] CMB fluctuations at the largest scales. A recent analysis [487] of the redshift-space large-scale (k < ∼ 0.3 h/Mpc) power spectrum of the Updated Zwicky catalog [208], which includes CfA2 and SSRS, was done using the quadratic estimator and decorrelation techniques (see Sects.…”

We review the formalism and applications of non-linear perturbation theory (PT) to understanding the large-scale structure of the Universe. We first discuss the dynamics of gravitational instability, from the linear to the non-linear regime. This includes Eulerian and Lagrangian PT, non-linear approximations, and a brief description of numerical simulation techniques. We then cover the basic statistical tools used in cosmology to describe cosmic fields, such as correlations functions in real and Fourier space, probability distribution functions, cumulants and generating functions. In subsequent sections we review the use of PT to make quantitative predictions about these statistics according to initial conditions, including effects of possible non Gaussianity of the primordial fields. Results are illustrated by detailed comparisons of PT predictions with numerical simulations. The last sections deal with applications to observations. First we review in detail practical estimators of statistics in galaxy catalogs and related errors, including traditional approaches and more recent developments. Then, we consider the effects of the bias between the galaxy distribution and the matter distribution, the treatment of redshift distortions in three-dimensional surveys and of projection effects in angular catalogs, and some applications to weak gravitational lensing. We finally review the current observational situation regarding statistics in galaxy catalogs and what the future generation of galaxy surveys promises to deliver.

Aims. We propose a new description of astronomical dust emission in the spectral region from the far-infrared to millimeter wavelengths. Methods. Unlike previous classical models, this description explicitly incorporates the effect of the disordered internal structure of amorphous dust grains. Our model is based on results from solid state physics used to interpret laboratory data. The model takes into account the effect of absorption by disordered charge distribution, as well as the effect of absorption by localized two level systems. Results. We review constraints on the various free parameters of the model from theory and laboratory experimental data. We show that, for realistic values of the free parameters, the shape of the emission spectrum will exhibit very broad structures whose shape will change in a non trivial way with the temperature of dust grains. The spectral shape also depends upon the parameters describing the internal structure of the grains. This opens new perspectives for identifying the nature of astronomical dust from the observed shape of the FIR/mm emission spectrum. A companion paper will provide an explicit comparison of the model with astronomical data.
