Next Monthly Meeting:
How do Galaxies Get their Shapes?
Dr. Angela Collier
Thursday, April 15th 7:00 via Zoom
Astronomers classify galaxies into three categories, based on their morphology: elliptical, spiral and irregular. Each type of galaxy spans a wide range of size, kinematic properties, and chemical makeup. The appearances of galaxies are shaped over billions of years by interactions with other galaxies and internal dynamical processes. While we do not know for sure how galaxies form to take these different shapes observed today we can find clues in galactic simulations. I will discuss the current state of the field and my own work on dark matter interactions within galaxies.
Angela Collier is a theoretical physicist who explores the role of dark matter interactions in large scale secular dynamics through analytical calculations and numerical simulations. She currently works at JILA and CU Boulder as a research postdoctoral fellow in the Eccentric Dynamics Group. She is originally from eastern Kentucky.

LAS Joins Boulder County Parks & Open Space to Observe International Dark Sky Week
International Dark Sky Week, April 5-12, is set aside to discover more about the constellations, planets, and celestial objects above our heads, and the dark skies that make these possible to see. Light pollution often obliterates our ability to see the skies, and causes harm in various ways to both humans and wildlife.
Boulder County Parks & Open Space is teaming up with the Longmont Astronomical Society to bring you daily emails April 5-9 with fun facts about dark skies, sky views, and ways you can help combat light pollution.
You can sign up to receive emails on the Boulder County Events webpage.
Learn more about how to be dark-sky friendly on our Light Pollution page.
