The Milky Way and the Local Group (MWLG)
  • Publication
    Integral field spectroscopy of selected areas of the Bright bar and Orion-S cloud in the Orion nebula
    We present integral field spectroscopy of two selected zones in the Orion nebula obtained with the Potsdam Multi-Aperture Spectrophotometer, covering the...
  • Publication
    Integral field spectroscopy of the brightest knots of HH 223 in L723
    HH 223 is the optical counterpart of a larger scale H2 outflow, driven by the protostellar source VLA 2A, in L723. Its poorly collimated and rather chaotic...
  • Publication
    Integrated-light analyses vs. colour-magnitude diagrams. II. Leo A: an extremely young dwarf in the Local Group
    Context. Most of our knowledge of the stellar component of galaxies is based on the analysis of distant systems and comes from integrated light data. It is...
  • Publication
    Interactions between large-scale radio structures and gas in a sample of optically selected type 2 quasars
    Context. The role of radio mode feedback in non radio-loud quasars needs to be explored in depth to determine its true importance. Its effects can be identified...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
