Abstract:
I will present the results of our search for Radio Recombination Lines using the Low Frequency Array (LOFAR). Our goal is to study the cold gas component of the interstellar medium of galaxies, for which low-frequency radio recombination lines can provide a unique and sensitive probe. They can be used to determine physical properties of the gas, such as temperature and density. The frequency coverage, resolution and sensitivity of LOFAR has opened up a new way to study the cool diffuse gas in Galactic and extragalactic sources out to cosmological distances.
In preparations for the future SKA, I will also present the efforts of our team FORSKA-Sweden in identifying neutral hydrogen emission from galaxies in a large simulated datacube using machine-learning techniques within the SKA Data Challenge 2.
