Sample interview questions: Explain any experience you have with analyzing data from astronomical surveys.
Sample answer:
-
Experience with Analyzing Data from the Sloan Digital Sky Survey (SDSS):
- Utilized Python and SQL to extract and process large datasets from the SDSS database.
- Developed custom data analysis pipelines to identify and characterize galaxies, quasars, and other astronomical objects.
- Performed statistical analysis to investigate the properties of these objects and their relationship to the large-scale structure of the universe.
-
Experience with Analyzing Data from the Dark Energy Survey (DES):
- Contributed to the DES collaboration’s effort to measure the expansion history of the universe using data from the DES camera.
- Used machine learning algorithms to classify galaxies and measure their redshifts from DES images.
- Developed methods to correct for systematic errors in the data and estimate the cosmological parameters from the DES measurements.
-
Experience with Analyzing Data from the Atacama Large Millimeter Array (ALMA):
- Utilized the ALMA data reduction software to process raw ALMA observations of molecular gas in galaxies.
