SUMMARY:Speaker: Rupert Croft (CMU) - Title: Cosmological simulations\, AI and the high redshift Universe
DESCRIPTION:Research Progress Meeting \nDate: April 30\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Rupert Croft (CMU) \nTitle: Cosmological simulations\, AI and the high redshift Universe \nAbstract: AI assistance can turn complex astrophysical supercomputer simulations into easily accessible tools. I will introduce applications to cosmology\, including hybrid AI-physics codes\, and a agentic system that can set up and run a billion particle simulation in seconds. As a use case for this type of modelling\, I will explore the Lyman-alpha forest of intergalactic absorption in quasars and how it can both be gravitationally lensed\, and also used to make large-scale maps of the intergalactic radiation intensity. I will also present cold dark matter simulation predictions for the mysterious “little red dots” seen by the Webb telescope at high redshift. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Jo Dunkley (Princeton) - Title: Cosmology from the Cosmic Microwave Background
DESCRIPTION:Research Progress Meeting \nDate: May 7\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Jo Dunkley (Princeton) \nTitle: Cosmology from the Cosmic Microwave Background\n \nAbstract: The cosmic microwave background (CMB) is our earliest image of the universe. I will review what our current observations have told us about the current model for the universe. I will then talk about science plans for the Simons Observatory\, a new millimeter-wave observatory in Chile which has substantial Berkeley involvement. With its smaller telescopes we are seeking a signal imprinted by gravitational waves generated in the early universe. Its largest telescope will measure the finer scales of the CMB with increased sensitivity\, probing the initial conditions of the early universe as well as revealing the later-formed cosmic web of gas and dark matter. I will describe SO’s current status and show some early data. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Emanuele Castorina (University of Milan) - Title: Probing the nature of Dark Matter with the Large Scale Structure of the Universe
DESCRIPTION:Research Progress Meeting \nDate: May 14\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Emanuele Castorina (University of Milan) \nTitle: Probing the nature of Dark Matter with the Large Scale Structure of the Universe \nAbstract: In the standard cosmological model\, the main non-baryonic component is defined by its acronym: Cold Dark Matter (CDM). In this talk I will show how measurements of the clustering of galaxies on scales larger than roughly 10 Mpc can place leading constraints on the physical properties behind each one of the acronym’s letters\, provided non-linearities in the matter distribution due to new physics are properly modeled via effective theories. Worked out examples will include ultra-light axions\, strong kinetic coupling at late times\, and tests of the equivalence principle in the dark sector. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239
