Monthly Meeting – Public Invited

 

Abstract:

Galaxy clusters are the most massive gravitationally bound objects in the universe. Their hot ionized gas scatters photons of the cosmic microwave background, creating a microwave spectrum distortion (called the Thermal Sunyaev-Zeldovich Effect) which recent experiments have used to identify thousands of clusters. Velocities of these clusters with respect to the cosmic rest frame can be probed using a related hot-gas scattering effect (the Kinematic Sunyaev-Zeldovich Effect) or a subtle gravitational lensing effect (the transverse lensing effect). I will describe these effects and their detection prospects in upcoming cosmic microwave background experiments. Velocities of galaxy clusters reflect the growth of structure in the universe, and so provide one route to probing whether the accelerating expansion of the universe is due to some mysterious dark energy or to a modification of general relativity on cosmological scales.

Bio:

Arthur Kosowsky is Professor and Chair of Physics and Astronomy at the University of Pittsburgh. He received his Ph.D. from the University of Chicago in 1994 and spent three years as a Junior Fellow at Harvard University before taking a faculty job at Rutgers University. He moved to Pittsburgh in 2005. Major research interests have included the cosmic microwave background radiation, properties of the universe, and gravitational waves. Kosowsky was a founding member of the Atacama Cosmology Telescope collaboration and the Simons Observatory collaboration.

Sky Meadows State Park Lyrid Meteor Shower Viewing @ Sky Meadows State Park

RSVP here.

This family-friendly event, made possible by the Friends of Sky Meadows, provides a relaxing opportunity to learn the importance of dark sky conservation, have a chance to view the Lyrid meteor shower while having the unique experience of being in the park after dark. Begin the evening with a kid-friendly segment exploring the nocturnal animals that call Sky Meadows home. Join NASA JPL Ambassadors and members of the Northern Virginia Astronomy Club (NOVAC) as they discuss the natural phenomenon of a meteor shower. Explore steps you can take back home to reduce light pollution with the International Dark-Sky Association. Later in the evening view the Lyrid Meteor Shower with the Northern Virginia Astronomy Club as they guide visitors through the night sky.

Tickets are $30 per vehicle (no more than 6 people per ticket). Water and breakfast will be provided, additional snacks available for purchase. Alcohol is prohibited.
