Crowded Field 3D Spectroscopy

The quantitative spectroscopy of stellar objects in complex environments is mainly limited by the ability of separating the object from the background. Standard slit spectroscopy, restricting the field of view to one dimension, is obviously not the proper technique in general. The emerging Integral Field (3D) technique with spatially resolved spectra of a two-dimensional field of view provides ...

Near–Infrared Spectroscopy and Young Stellar Populations

Over the past decade, tremendous progress has been made in applying the techniques of MK classification to spectra obtained from 1–5 μm. This spectral region is rich in atomic and molecular features which are temperature and luminosity sensitive providing a powerful technique to study intrinsically red and/or heavily dust embedded stellar populations. We will summarize recent work with particul...

3D Force Field Spectroscopy

With recent advances in instrumentation and experimental methodology, noncontact atomic force microscopy is now being frequently used to measure the atomic-scale interactions acting between a sharp probe tip and surfaces of interest as a function of three spatial dimensions, via the method of three-dimensional atomic force microscopy (3D-AFM). In this chapter, we discuss the different data coll...

EAGLE Spectroscopy of Resolved Stellar Populations Beyond the Local Group

We give an overview of the science case for spectroscopy of resolved stellar populations beyond the Local Group with the European Extremely Large Telescope (E-ELT). In particular, we present science simulations undertaken as part of the EAGLE Phase A design study for a multi–integral-field-unit, near-infrared spectrograph. EAGLE will exploit the unprecedented primary aperture of the E-ELT to de...

Near-infrared spectroscopy of stellar populations in nearby spiral galaxies

We present high spatial resolution, medium spectral resolution near-infrared (NIR) Hand K-band long-slit spectroscopy for a sample of 29 nearby (z < 0.01) inactive spiral galaxies, to study the composition of their NIR stellar populations. These spectra contain a wealth of diagnostic stellar absorption lines, e.g., Mg I 1.575 μm, Si I 1.588 μm, CO (6–3) 1.619 μm, Mg I 1.711 μm, Na I 2.207 μm, C...
