Brad Cenko: The Zwicky Transient Facility

May 25, 2018, 4:00 PM - 5:00 PM

Title: The Zwicky Transient Facility

Speaker:Brad Cenko, NASA

Abstract: Thanks in large part to Moore’s Law (applied both to Si-based CCD detectors and computational/storage capabilities), it has recently become possible to conduct sensitive optical imaging over large areas of the sky with a regular cadence. This “celestial cinematography” has revolutionized our picture of the transient and variable sky, with implications ranging from cosmology to the end fate of massive stars. In this talk I’ll describe the next great leap forward in wide-field optical imaging, the Zwicky Transient Facility (ZTF). A custom-built camera provides a 47 square degree field-of-view on the Palomar 48 inch Oschin Schmidt telescope, yielding more than an order of magnitude improvement in survey speed relative to its predecessor survey, the Palomar Transient Factory (PTF). ZTF achieved first light in October 2017, and I will provide an update on the project status and some early science results.

Title: The Puzzle of Liquid Water: New Insights for Physics, Chemistry, & Biology

Speaker:Eugene Stanley, Boston University 

Abstract: We will discuss recent progress in understanding water's 73 documented
anomalies. We will combine information provided by new experiments
and new simulations on water in bulk, nanoconfined, and biological
environments designed to test the hypothesis that liquid water has
behavior consistent with the novel phenomenon of “liquid polymorphism”
--- that at sufficiently low temperature water can exist in two
distinct phases. We will also briefly discuss how the general concept
of liquid polymorphism is proving useful in understanding anomalies in
other liquids, such as silicon, silica, and carbon, which have in
common that they are characterized by two characteristic length scales
in their interactions.
