Notes to Availability Přístup pouze pro oprávněné uživatele Audience Suitable for anybody starting from graduate or senior undergraduate student level in physics or astronomy. While the main target group is graduate students who want to start working on the topic, the text is equally suitable for active researchers who either aim to enter the topic or who are already experts in one of the fields involved but want to get introduced to other aspects of sterile neutrino Dark Matter. A basic knowledge of the standard models of particle physics and of cosmology is needed to understand the text, however, many aspects are briefly reviewed, too. Note Způsob přístupu: World Wide Web..

book
This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter, challenging some of the standard assumptions which may be true for some Dark Matter candidates but not for all. So, this can be seen either as an introduction to a specialized topic or an out-of-the-box introduction to the field of Dark Matter in general. No matter if you are a theoretical particle physicist, an observational astronomer, or a ground-based experimentalist, no matter if you are a grad student or an active researcher, you can benefit from this text, for a simple reason: a non-standard candidate for Dark Matter can teach you a lot about what we truly know about our standard picture of how the Universe works.
