Description
It is shown on the basis of a complete sample of Virgo cluster galaxies and a larger set of varied data from the literature that ellipticals, early-type dwarfs, and bulges of S0s and spiral form two distinct families in the plane of the effective parameters mu(e) and R(e). While the 'normal' family encompasses all galaxies fainter than M(B) of -19.3, the 'bright' family is made up of the brightest cluster members and by the host galaxies of QSOs. The existence of this dichotomy bears on the use of the fundamental plane to probe extragalactic distances.

    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

    Measuring the Masses of the TOI-700 Planets with ESPRESSO

    Over the past three decades, astronomers have discovered that small, rocky planets in temperate orbits are common around our neighboring stars. Whether or not these planets can maintain atmospheres is an open question in the field. Recently, considerable attention in this search has been focused on M dwarfs stars, as their small sizes make it

    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
