Astro Seminar: "Beyond Pluto: The Hunt for Planet X"
Scott Sheppard (Carnegie Institution for Science)
The Kuiper Belt, which has Pluto as the largest member, is a region of comet like objects just beyond Neptune. This belt of objects has an outer edge, which we are now only able to explore in detail. For the past…
ABO Seminars: "Label-free Optical Micro Imaging of Tissue Histology in Vivo"
Xingde Li (Johns Hopkins University)
This seminar will focus on our recent progresses on developing high-resolution biophotonic imaging technologies, particularly the second-generation optical coherence tomography (OCT) endoscopy and multiphoton…
Department Colloquium: "The Universe as a Lab for Fundamental Physics: Results from Spider and Future Suborbital Missions"
William Jones (Princeton) Hosted by James Aguirre
I will describe our recent results from observations of the Cosmic Microwave Background, including a status report on the recent flight of the Spider experiment, a balloon borne CMB polarimeter. I will also discuss…
Condensed Matter seminar: "Wavefront Shaping for in vivo Brain Imaging"
Na Ji, Janelia Research Campus
There are about the same number of stars in our galaxy as there are neurons in our brain. To study stars and neurons using optical imaging, we face similar challenges of image degradation by aberrations and…
Condensed Matter seminar: “Do entangled polymers possess a shear banding instability?”
Peter Olmsted, Georgetown University
The original Doi-Edwards theory (1978) predicted that long entangled polymers should become unstable to homogeneous shear flow for shear rates exceeding the relaxation (reptation) time. At the time this seemed to…
Astro Seminar: "A Possible First Detection of High-Redshift Population III Stars"
Eli Visbal (Columbia)
The recent observation of CR7 (Sobral et al. 2015), the brightest Lyman-alpha emitter at z~7, could be the first detection of Pop III stars (i.e. stars formed from primordial/extremely metal-poor gas). CR7 has strong…
Department Colloquium: "Physics Opportunities at Future Circular Colliders"
Liantao Wang (U of Chicago) Hosted by Joe Kroll
Following the discovery of the Higgs boson, there has been a lot discussion about the next step in high energy physics. Among different options, a couple of newly proposed next generation circular colliders,…
