Investigation of the FIR-Radio correlation at small scales in the Galaxy
... In my PhD. Project I will study these correlations, most notably, the far-infrared and radio continuum correlation on scales corresponding to the size of small molecular clouds. I will also study the possibility that the correlation between CO and far-infrared luminosities is caused by strong select ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
