Quasar Spectroscopy Sound: Analyzing Intergalactic and Circumgalactic Media via Data Sonification

Document Thumbnail

In this paper, we present sonification approaches to support research in astrophysics, using sound to enhance the exploration of the intergalactic medium and the circumgalactic medium. Astrophysicists often analyze matter in these media using a technique called absorption line spectroscopy. Our sonification approaches convey key spectral features identified via this technique, including the presence and width of spectral absorption lines within a region of the Universe, the relationship of a particular redshift location with respect to the absorption peak of a spectral absorption line, and the density of gas at various regions of the Universe. In addition, we introduce Quasar Spectroscopy Sound, a novel software tool that enables researchers to perform these sonification techniques on cosmological data sets, potentially accelerating the discovery and classification of matter in the intergalactic medium and circumgalactic medium.
