    Infrared standards for ISO. I. A new calibration of mid infrared photometry
    We present N, 8.7 mu m, 9.8 mu m 12.5 mu m and Q bolometry of 26 stars which were observed on the IRTF. These are primarily K giants which have been well...

    Initial mass function variability from the integrated light of diverse stellar systems
    We present a uniform analysis of the stellar initial mass function (IMF) from integrated light spectroscopy of 15 compact stellar systems (11 globular clusters...

    Inner bars also buckle. The MUSE TIMER view of the double-barred galaxy NGC 1291
    Double bars are thought to be important features for secular evolution in the central regions of galaxies. However, observational evidence about their origin...

    Insights into formation scenarios of massive early-type galaxies from spatially resolved stellar population analysis in CALIFA
    We perform spatially resolved stellar population analysis for a sample of 69 early-type galaxies (ETGs) from the CALIFA integral field spectroscopic survey...

    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...

    Integral field spectroscopy of the gravitational lens HE1104-1805
    We present integral field spectroscopy of the double imaged quasar HE1104-1805 taken with the optical fiber system INTEGRAL-WYFFOS at the WHT telescope. From...

    Integral field spectroscopy supports atmospheric optics to reveal the finite outer scale of the turbulence
    Context. The spatial coherence wavefront outer scale (ℒ 0) characterizes the size of the largest turbulence eddies in Earth's atmosphere, determining low...

    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...

    Interlocking Resonance Patterns in Galaxy Disks
    We have developed a method for finding dynamical resonances in disk galaxies using the change in sense of the radial component of the in-plane velocity at a...
