Black Holes in our Universe

SPEAKER: Joshua Tan

Black Holes are, surprisingly, found in something of abundance in our universe from sizes that are only a little larger than our Sun to sizes that rival the masses of galaxies. I’ll share with you the evidence that we have for all these different kinds of black holes and discuss some of the many mysteries that remain for why and how these most exotic things in the universe exist and continue to excite our imaginations.

Speaker Bio:

Prof. Tan is an optical astronomer by training, intensely interested in short-period binary millisecond pulsars. Aside from that, open problems in binary modeling, neutron star physics, and three-body dynamics occupy most of his research thinkspace. Recently, he became entangled with a project to commission a research and teaching telescope at Grand Mesa Observatory outside of Grand Junction, Colorado with remote access observing from New York City, either from the Astrophysics Division at the American Museum of Natural History or from the comfort of the observer’s own home! The telescope is now operational and contributing light curves to the database of the American Association of Variable Star Observers.

The live meeting will be at Mesa Room Central Library.

The meeting will also be via Zoom for those who need or want to participate remotely. You will have to pre-register to participate via Zoom. Contact us here to register.

We hope to see everyone (either live or online)
