Titre : Gravitational Lensing Type de document : texte imprimé Auteurs : Scott Dodelson, Auteur Editeur : Cambridge ; New York ; Melbourne [UK ; USA] : Cambridge University Press (CUP) Année de publication : cop. 2017 Importance : 1 vol. (XII-224 p.-[8] p. de pl.) Présentation : ill. en noir et en coul. Format : 25 cm ISBN/ISSN/EAN : 978-1-107-12976-4 Note générale : Sommaire : 1. Overview . - 2. Deflection of Light. - 3. Multiple Images. - 4. Magnification. - 5. Microlensing. - 6. Weak Lensing : Galaxy Shapes .- 7. Mass from Shapes. - 8. Cosmic Shear. - 9. Lensing of the Cosmic Microwave Background. -- PPN 203407997 Langues : Anglais (eng) Tags : Lentilles gravitationnelles Rayonnement du fond du ciel Matière sombre Distances (cosmologie) Exoplanètes Galaxies -- Amas Gravitational lenses Cosmic background radiation GREAT [GRavitational lEnsing Accuracy Testing] Dark matter Cosmological distances MACHO [Massive compact Halo Object] Extrasolar planets Galaxy -- Clusters Index. décimale : 521.1 Gravitation (mécanique céleste) Résumé : Gravitational lensing is a consequence of general relativity, where the gravitational force due to a massive object bends the paths of light originating from distant objects lying behind it. Using very little general relativity and no higher level mathematics, this text presents the basics of gravitational lensing, focusing on the equations needed to understand the phenomena. It then applies them to a diverse set of topics, including multiply imaged objects, time delays, extrasolar planets, microlensing, cluster masses, galaxy shape measurements, cosmic shear, and lensing of the cosmic microwave background. This approach allows undergraduate students and others to get quickly up to speed on the basics and the important issues. The text will be especially relevant as large surveys such as LSST and Euclid begin to dominate the astronomical landscape. Designed for a one semester course, it is accessible to anyone with two years of undergraduate physics background.

Titre : Modern cosmology Type de document : texte imprimé Auteurs : Scott Dodelson, Auteur ; Fabian Schmidt, Auteur Mention d'édition : 3rd edition Année de publication : 2026, cop. 2026 Importance : 1 volume (xvi-502 p.) Présentation : ill. en coul., couv. ill. en coul. Format : 24 cm ISBN/ISSN/EAN : 978-0-443-28828-9 Note générale : PPN 284648914 Langues : Anglais (eng) Tags : Cosmologie Astrophysique Big bang Matière noire (astronomie) Cosmology Astrophysics Big bang theory Dark matter (Astronomy) Index. décimale : 523.01 Astrophysique Résumé : Résumé : Modern Cosmology, Third Edition, provides a detailed introduction to the field of cosmology. Beginning with the smooth, homogeneous universe described by a Friedmann-Lemaître-Robertson-Walker metric, this trusted resource includes careful treatments of dark energy, Big Bang nucleosynthesis, recombination, and dark matter. The reader is then introduced to perturbations about an FLRW universe: their evolutionwith the Einstein-Boltzmann equations, their primordial generation by inflation, and their observational consequences: the acoustic peaks in the CMB; the E/B decomposition in polarization, gravitational lensing of the CMB, and large-scale structure; and the BAOstandard ruler and redshift-space distortions in galaxy clustering. Not least, it also covers nonlinear structure formation including perturbations theory and simulations. The revised third edition adds presentations on emerging probes and concludes with a substantially updated chapter on data analysis. Modern Cosmology, Thirs Edition, shows how current observations are rapidly revolutionizing our picture of the universe and supplies the readers with all the tools needed to work in cosmology.
