Description
The Milky Way and Andromeda galaxies are the largest members of the Local Group, and their evolution is affected by the evolution of their host as a whole. At the same time, they themselves play an important role in the evolution of the Local Group. Considerable information can be obtained for the Local Group, but little is known about the distances and the full star-formation history of its galaxies. RGB and AGB stars are the keys to trace the full star-formation history of nearby galaxies. These stars are usually the most prominent population of dwarf spheroidal galaxies, but it has been shown (Gallart et al. 1994; Aparicio & Gallart 1994) that they are also observable in dwarf irregular galaxies. This will open the door to the study of the earliest star-formation processes taking place in these galaxies. The star-formation history of the Local Group galaxies is a crucial piece of information for answering basic questions about the evolutionary history of the group.

    Workshop summary: Kaons@CERN 2023

    Kaon physics is at a turning point - while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscape needs to be defined. With HIKE, KOTO-II and LHCb-Phase-II on the table and under scrutiny, it is a very good moment in time to take stock and contemplate about the

    3.5 years of observing exoplanet day sides with CHEOPS

    Characterising Exoplanets Satellite (CHEOPS) is the first ESA exoplanet space mission. The satellite carries a 30cm telescope, optimised to deliver exquisite (ppm-level) photometry of bright exoplanetary systems at optical wavelengths. CHEOPS has spent approximately 20% of its observing time during its 3.5-year long nominal mission studying

    Finding Water Worlds with Transit Timing Variations

    Models predict that planets with water-rich compositions may be common around low-mass stars, but definitive evidence for the existence of water worlds has remained elusive. Precise mass and radius measurements for small planets allow us to identify candidate water worlds that have bulk densities too low to be consistent with a rocky composition
