Line Intensity mapping as a cosmology probe
Line intensity mapping is a relatively new observational technique, and it is aimed at detecting and probing the properties of faint and/or extended sources. I will describe the Intensity Mapping Technique focusing on its advantages compared to traditional galaxy surveys. Moreover, I will discuss the challenges associated with probing light emission with Line-IM, such as technical requirements, foreground removal and signal analysis. Intensity Mapping missions were initially taught of as a new potentially powerful cosmology probe. I will present some of the cosmology constraints which are the aim of current and future Intensity Mapping missions.
