Our February 14 2025 GAAC meeting will feature a talk by University of Minnesota researcher Christina Andrade, core team member of the GRANDMA collaborative study of gravitational wave sources, and head of operations for the related Kilonova-Catcher citizen science project. A kilonova is a bright blast produced when two massive objects, two neutron stars, or a neutron star and a stellar-mass black hole, collide and merge. This enormous collision produces electromagnetic radiation as well as gravitational waves. The gravitational waves alert us and direct us to the kilonova, so that we can observe it with optical and infrared telescopes. These observations complement those by gravitational wave detectors like LIGO. For more information on the projects, see the University of Minnesota GRANDMA page here <https://experts.umn.edu/en/publications/the-grandma-network-in-preparation-for-the-fourth-gravitational-w>, and also the Kilonova Catcher citizen science project site here <http://kilonovacatcher.in2p3.fr/>. GRANDMA, of course, stands for Global Rapid Advanced Network Devoted to the Multi-messenger Addicts. This one will be fun, folks. Come get some entertaining and cutting-edge astronomy, with decaf and snacks, old friends and new, great conversation and free parking. I hope we'll see you there, 8:00 pm on Friday, February 14 at the Lanesville Community Center <https://maps.app.goo.gl/pntHAopkhrjho6XR9> or online.
