Determination of Time Dependence in the Temperature Structure of Ionized Interstellar Gas
It is well known that the temperature structure of ionized interstellar gas departs considerably from homogeneity. This is detected in the form of ``temperature...
Determining Magnesium and Silicon Abundances from CARMENES Spectra
The study of chemical abundances of stars that host planets is critical to our current un- derstanding of the structure, formation, evolution of rocky planets...
Determining the Local Black Hole Mass Function from the Pitch Angles of Nearby Spiral Galaxies
We present pitch angle measurements of a nearly complete sample of nearby spiral galaxies. Using these results along with the relationship between supermassive...
Determining the population of Cataclysmic Variables in the Globular Cluster NGC2808
Close binaries, and in particular cataclysmic variables (CVs), play a vital role in the dynamical evolution of globular clusters. It is, therefore, important to...
Development and capabilities of the ISOPHOT interactive analysis (PIA), a package for calibration and astronomical analysis.
The ISOPHOT Interactive Analysis PIA, is a calibration, scientific analysis and visualization tool for accessing and processing ISOPHOT data. ISOPHOT is one of...
Development of a 35-micron slicer-based Integral Field Unit for high-resolution 2D solar spectroscopy
Integral Field Spectropolarimetry (IFS) makes feasible the simultaneous measurement of a 2D field with the use of an Integral Field Unit (IFU). Slicer-based...
Development of a field-of-view scanning system (FoV-SS): test results and lessons learned
Here is presented the tests results and the lessons learnt concerning an opto-mechanical device to scan the GREGOR telescope field of view. The scanning is done...
