Full Description
Astronomy in Focus presents selected contributions from the scientific Focus Meetings chosen to be held at IAU General Assemblies. This edition is for the XXXI General Assembly for which the non-business sessions were held in Busan, 2-11 August 2022 following a one-year delay in consequence of the COVID pandemic. Focus Meetings are proposed by groups of scientists with an aim to promote cross-disciplinary interactions while maintaining a well-defined focus on a particular topic. They often address a new scientific area or an emerging field. At the IAU XXXI General Assembly, ten focus meetings complemented the scientific program of seven Symposia that are published separately. The Focus Meetings represented here cover dark and quiet sky protection, together with phenomena related to the Solar System and exoplanets, stars and star clusters, relativistic jets, the intracluster medium, and cosmic shear.
