Line intensity mapping (LIM) is an emerging observational technique with the potential to greatly enhance our understanding of both cosmology and astrophysics. By probing the large-scale structure of the universe in three dimensions across a wide range of scales and cosmic epochs, LIM offers the ability to tackle many unresolved questions in cosmology, such as the physics of inflation, the properties of neutrinos, the nature of dark matter and dark energy, and the theory of gravity. In astrophysics, LIM observations at different wavelengths enable us to investigate various phases of the interstellar and intergalactic medium, providing valuable insights into the processes behind reionization and galaxy formation. Performing intensity mapping in different wavelengths would enable us to obtain robust detection of LIM signals and assure their cosmological/astrophysical origin, and enhance the scientific return of individual observations. Despite its promise, LIM is still a relatively young field, which naturally comes with a range of instrumental, observational, and theoretical challenges that need to be addressed. The success of LIM as a reliable probe in both astrophysics and cosmology therefore depends heavily on the collaboration of experts across these areas.
LIM25 conference, the 9th edition of a series that began in 2016 (last two at Max-Planck Institute for Astrophysics, Germany (2023), and University of Illinois, NCSA, USA (2024)), seeks to bring together specialists from various disciplines central to LIM research. The event will focus on addressing current challenges, showcasing recent advances, discussing obstacles encountered during early experiments, and exploring prospects for large-scale surveys. By fostering these interactions, the conference will help to maximize LIM’s potential as a powerful tool for both cosmology and astrophysics, while cultivating a vibrant, collaborative scientific community.
The event will be held in person and we anticipate an audience of 70–100 participants.
