Infrared Study of Fullerene Planetary Nebulae
We present a study of 16 planetary nebulae (PNe) where fullerenes have been detected in their Spitzer Space Telescope spectra. This large sample of objects...
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...
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...
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...
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...
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...
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...
