Join us on March 11th as the UW-Milwaukee Coffeeshop Astrophysics group presents: Who Hid the Sun?

On Monday, April 8, 2024, the Moon will pass between the Earth and the Sun, creating a total solar eclipse whose path will cross over North America. In this talk, the members of UW-Milwaukee's Coffeeshop Astrophysics group will prepare you for this extraordinary astronomical event! Come learn about what happens during an eclipse, the differences between solar and lunar eclipses, how they have influenced various cultures, what role they have played in history, and how we can safely view it.

Pratyusava Baral grew up in Kolkata, India and earned his undergraduate degree from Presidency University. He joined UWM in the spring of 2021. As a member of the LIGO Scientific Collaboration, Pratyusava works on detecting gravitational waves. He uses methods of parameter estimation to learn more about the black holes and neutron stars that create these ripples in spacetime. In his free time, Pratyusava likes to hike and paint.

Leith Benali is a 1st year graduate student from Warrenton, Virginia. He got his Bachelor's degree in Physics with a minor in mathematics at George Mason University. Driven by curiosity about the nature of the universe, Leith will soon join the NANOGrav collaboration to study low-frequency gravitational waves. Outside of physics, Leith loves to cook/bake, practice martial arts, and play trombone.

Join us on February 12th as Milwaukee Riverkeeper's Cheryl Nenn presents: State of Milwaukee's Rivers and Lake Michigan

Cheryl Nenn, Riverkeeper for Milwaukee Riverkeeper, will discuss the current state of Milwaukee's rivers, including the current status of water quality, habitat restoration, and fish passage efforts. She will also touch on a generational opportunity to clean up historic contaminants from the Milwaukee River Estuary Area of Concern, including over 20 planned habitat and beach restoration projects. The talk will also explore how many emerging contaminants threaten local water quality - including pharmaceuticals, personal care products, PFAS and road salt.
