Description
Considering that the recent history of E-S0 galaxies can be approximated by Pure Luminosity Evolution (PLE), we have examined a set of PLE models in order to delimit the epoch in which the majority of the red galaxy population moved away from this simple evolution framework. The models assume that they were assembled and formed most of their stars at a given formation redshift (z f), and that they have evolved without merging or substantial dust obscuration since then. Comparing the model predictions with real data, we conclude that most of E-S0’s at low and intermediate luminosities must have been progressively built up at 1 < z < 2, being the bulk of formation at z ˜ 1. 5, as recently claimed by several observational studies.

    The Aligned Orbit of a Hot Jupiter around the M Dwarf TOI-4201
    Measuring the obliquities of stars hosting giant planets may shed light on the dynamical history of planetary systems. Significant efforts have been made to measure the obliquities of FGK stars with hot Jupiters, mainly based on observations of the Rossiter–McLaughlin effect. In contrast, M dwarfs with hot Jupiters have hardly been explored because

    Einasto Gravitational Potentials have Difficulty to Hold Spherically Symmetric Stellar Systems with Cores
    It was known that an ideal spherically symmetric stellar system with isotropic velocities and an inner core cannot reside in a Navarro, Frenk, and White (NFW) gravitational potential. The incompatibility can be pinned down to the radial gradient of the NFW potential in the very center of the system, which differs from zero. The gradient is

    ROSALIA: ROman Sky Analyst for Low surface brightness Imaging &amp; Astronomy
    Diffuse emission in the outskirts of galaxies, such as stellar tidal streams, galaxy stellar halos and intracluster light, provides important constraints on the structure and evolution of the Universe. However, such low surface brightness diffuse emission can be up to thousands of times dimmer (>29 AB mag/[square arcseconds]) than the sky
