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.

    Study of basaltic asteroids through their phase curves
    Introduction Classified as type-V, the basaltic asteroids of the Main Belt (MB), for the most part, are connected to Vesta's dynamic family. However, since the discovery of the V-type asteroid (1459) Magnya in the outer MB, several new asteroids have been found in different regions, including V-types from inner regions not belonging to the Vesta

    NEOMIR: ESA's space-based infrared mission for NEO detection and early warning
    The Near-Earth Object Mission in the Infra-Red (NEOMIR) is the first ESA's space-based mission fully dedicated to discovering near-Earth objects (NEOs), with a focus to detect and raise early warning for the smaller objects that are coming from the Sun direction, thus nearly impossible to be detected by ground-based optical survey. NEOMIR is

    Upgrading the polarisation modulation unit of the Gregor Infrared Spectrograph
    The Gregor Infrared Spectrograph (GRIS) is installed at the Gregor telescope at Observatorio del Teide, Spain. The instrument started observations in 2012 and underwent several upgrades in the following years. Currently, it is experiencing the most significant upgrade so far, which includes, among other things, adding two optical channels to
