2017 Spring Science Colloquia
Amy Reines  (National Optical Astronomy Observatory)
The origin of supermassive black holes remains a major outstanding issue in modern astrophysics. These monster black holes reside in the nuclei of essentially every massive galaxy and power the most luminous quasars at the edge of the observable Uni ...

2017 Spring Science Colloquia
Jessica Lu  (University of California Berkeley)
Our Galaxy most likely hosts 10^8-10^9 million stellar mass black holes. The exact number and mass function of these black holes contains important information regarding our Galaxy's star formation history, stellar mass function, and the fate of very ...

2017 Spring Science Colloquia
Renee Hlozek  (Dunlap Institute, University of Toronto)
CMB cosmology is currently undergoing a data-rich epoch, with measurements on small scales from experiments like the Atacama Cosmology Telescope (ACT) and its polarisation instrument, ACTPol, adding to measurements on larger scales by Planck, WMAP an ...

2017 Spring Science Colloquia
Mike Brown  (California Institute of Technology)
The recent suggestion of evidence for a massive ninth planet in the outer solar system has set off a worldwide search to find the latest member of our planetary family. I will discuss the evidence for the planet and show how we are working to constra ...

2017 Spring Science Colloquia
Eliza Kempton  (Grinnell College)
Discoveries of extrasolar planets over the last two decades have reshaped our understanding of how planetary systems form. Super-Earths – planets intermediate in size/mass between Earth and Neptune – do not exist in our Solar System, and the discove ...

2017 Spring Science Colloquia
Nikole Lewis (STSCI)
The past year has seen a bumper crop of Earth-sized exoplanets orbiting nearby stars, targets ripe for exoplanet characterization studies. The seven planets in the TRAPPIST-1 system, located 12 pc from our solar system, represent the largest number ...

2017 Spring Science Colloquia
Roberto Abraham (University of Toronto)
In this talk I will describe some early results from the Toronto/Yale/Harvard Dragonfly Telephoto Array (a.k.a. Dragonfly), a robotic imaging system optimized for the detection of extended ultra low surface brightness structures. Dragonfly is compris ...

2017 Spring Science Colloquia
Jim Fuller (California Institute of Technology))
Internal stellar magnetic fields are inaccessible to direct observations and little is known about their amplitude, geometry and evolution. I will discuss how strong magnetic fields in the cores of red giant stars can be identified with asteroseismol ...
