Samenvatting

This book introduces the phenomenology of gravitational lensing in an accessible manner and provides a thorough discussion of the related astrophysical applications. It is intended for advanced undergraduates and graduate students who want to start working in this rapidly evolving field. This includes also senior researchers who are interested in ongoing or future surveys and missions such as DES, Euclid, WFIRST, LSST.

The reader is guided through many fascinating topics related to gravitational lensing like the structure of our galaxy, the searching for exoplanets, the investigation of dark matter in galaxies and galaxy clusters, and several aspects of cosmology, including dark energy and the cosmic microwave background.

The author, who has gained valuable experience as academic teacher, guides the readers towards the comprehension of the theory of gravitational lensing and related observational techniques by using simple codes written in python. This approach, beyond facilitating the understanding of gravitational lensing, is preparatory for learning the python programming language which is gaining large popularity both in academia and in the private sector.

        Wat is een AI-book?

        Een AI-book is niet een boek dat geschreven is door AI maar een boek dat verrijkt is met AI. Het maakt de inhoud van een boek interactief via WhatsApp, zodat je ermee kunt chatten. Zie het als een razend slimme assistent die het boek perfect begrijpt en er alles uit onthouden heeft. Jij kunt deze assistent alles vragen. Vraag bijvoorbeeld hoe je iets kunt toepassen op jouw persoonlijke situatie, om een korte samenvatting, of wat de belangrijkste inzichten zijn. AI-books zijn alleen te gebruiken via WhatsApp, je hoeft er geen aparte app voor te installeren.
