Description
Most of the information concerning the ionized gas and star kinematics in the central regions of galaxies is 1-Dimensional. This hampers the study of the velocity fields, specially for the ionized gas which in many cases exhibits a kinematics strongly decoupled from that of the stars. Here we present the velocity fields for the ionized gas and the stars obtained from 2D fiber-spectroscopy in the central regions (12' 'times 9 ' ') of a sample of active (NGC 1052, NGC 1068, NGC 3516, NGC 4151, NGC 6500, M87) and non-active (M31, M32, NGC 7331) galaxies. These data will be useful to study and compare the stellar and ionized gas kinematics in galactic nuclei, overcoming the geometrical ambiguities common to 1D studies.

    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

    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

    ROSALIA: ROman Sky Analyst for Low surface brightness Imaging & 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
