SUMMARY:Speaker: Kirit Karkare (Boston University) - Title: On-Chip Millimeter-Wave Spectroscopy for Line Intensity Mapping: SuperSpec and SPT-SLIM
DESCRIPTION:Research Progress Meeting \nDate: February 12\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Kirit Karkare\, Boston University \nTitle: On-Chip Millimeter-Wave Spectroscopy for Line Intensity Mapping: SuperSpec and SPT-SLIM \nAbstract: Answering outstanding questions in cosmology – such as understanding the nature of inflation\, dark energy\, and reionization – requires observations of ever-increasing volumes of the universe. In this talk I will discuss how we can use line intensity mapping (LIM) of far-IR emission lines to measure large volumes at high redshift. This technique is enabled by advances in millimeter-wave spectrometer technology. I will present two on-chip spectrometer projects: SuperSpec\, which pioneered the concept and was deployed to the Large Millimeter Telescope\, and SPT-SLIM\, a pathfinder LIM experiment at the South Pole. Both projects saw first light in 2025. I will discuss what we’re learning from their first observations and outline the path towards large\, dense focal planes with the sensitivity required for next-generation cosmology. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239
