    Internal kinematics of dwarf satellites of MW/M31-like galaxies in TNG50
    We present a kinematic study of a thousand of dwarf satellites of MW/M31-like hosts from the IllustrisTNG50 simulation. Internal kinematics were derived for all...

    Internal rotation of Milky Way dwarf spheroidal satellites with Gaia Early Data Release 3
    We present an analysis of the kinematics of 14 satellites of the Milky Way (MW). We use proper motions (PMs) from the Gaia Early Data Release 3 (EDR3) and line...

    Intrinsic Colors and Ages of Extremely Red Elliptical Galaxies at High Redshift
    In order to know the formation epoch of the oldest elliptical galaxies as a function of mass and observed redshift, a statistical analysis of 333 extremely red...

    Investigating Phosphorus Abundances in a Sample of APOGEE-2 Bulge Globular Clusters
    Phosphorus-enhanced (P-rich; [P/Fe] ≳ +0.8) giants have been found among mildly metal-poor field stars, but in only one star in a globular cluster (GC), M4 (NGC...

    Ionization correction factors for sodium, potassium, and calcium in planetary nebulae
    We use a large grid of photoionization models that are representative of observed planetary nebulae (PNe) to derive ionization correction factors (ICFs) for...

    Ionized gas diagnostics from protoplanetary discs in the Orion nebula and the abundance discrepancy problem
    We present results from integral field spectroscopy of a field located near the Trapezium Cluster using the Potsdam Multi-Aperture Spectrophotometer (PMAS). The...

    Ionized gas in the XUV disc of the NGC 1512/1510 system
    We present deep, intermediate-resolution, optical spectroscopy of 136 genuine UV-bright regions located in both the inner and outer regions of NGC 1512. This...

    IRAS 17423-1755 (Hen 3-1475) Revisited: An O-rich High-mass Post-asymptotic Giant Branch Star
    The high-resolution (R ~ 600) Spitzer/IRS spectrum of the bipolar protoplanetary nebula (PN) IRAS 17423-1755 is presented in order to clarify the dominant...

    Iron and s-elements abundance variations in NGC 5286: comparison with `anomalous' globular clusters and Milky Way satellites
    We present a high-resolution spectroscopic analysis of 62 red giants in the Milky Way globular cluster (GC) NGC 5286. We have determined abundances of...
