Astrophysical Lessons from Gravitational-wave Detections

Zoom

Sharan Banagiri, Northwestern University

The last decade has seen the rapid rise of gravitational-wave astronomy, made possible by the astonishingly sensitive LIGO and Virgo gravitational-wave detectors. The number of gravitational wave detections has skyrocketed and each year seems to promise something new. Sharan will give a brief introduction to gravitational-wave astronomy and then will describe the latest discoveries and what they tell us about the universe; including the first intermediate-mass black holes ever detected and the first potential neutron star black-hole binaries. Sharan will then give an outlook for the future and what new things we can expect over the next decade.

Urban Astrophotography 101: Planetary Imaging

Zoom

Thursdays, 7 PM. Sept. 30; Oct. 7, 14, 21, 28; Nov. 4

Urban AP 101 teaches the use of Planetary Cameras and software (cameras and software designed specifically for this purpose) which go to the next level – pulling surprising detail from small amateur telescopes, even from the heart of the city. We expand on material of previous UAP classes but now focus on telescope astro cams, not on DSLR cameras.

Introduction to Night Sky Photography

Zoom

Tuesdays, 7 PM. Oct. 26 (NEW), Nov. 2, 16 (field day), 23, 30; Dec. 7

Don’t put your camera away when the sun sets! Learn how to shoot the night sky with landscapes with a digital SLR or mirrorless camera and ordinary lenses (not through telescopes). How to shoot well composed and exposed starscapes, night sky landscapes, eclipses, the moon, astronomical phenomena. This will be an in-depth course about wide field night sky photography.
