Project Description: This project will use imaging data obtained with the James Webb Space Telescope to select photometrically galaxies with intense emission lines, using the complete sample of galaxies in the JADES survey. This work will allow identifying galaxies with significant presence of active galactic nuclei (AGN) as well as extreme starbursting galaxies, and complements a previous work that used the JADES data available in 2023. These measurements will be used to estimate the volume density of these types of objects and determine how these evolve compared to more local samples (SDSS, DESI).
NASA Relevance: This research uses data coming from two of the NASA flagship observatories - the James Webb and Hubble Space Telescopes - and seeks to understand how galaxies formed and evolved.
Work Description: The intern will analyze existing catalogs of distant galaxies with multi- band photometry to identify galaxies with strong emission lines. Matching galaxies to catalogs of galaxies with spectroscopic measurements, will allow using them as templates which can be used to classify galaxies without spectroscopic measurements. With these detections the intern will measure the space density of sources, after correcting for known selection biases. These will then be compared to estimates measured from low redshift samples.
