Kavli Affiliate: Alexander Ji | First 5 Authors: Alexander P. Ji, Anna Frebel, , , | Summary: The ultra-faint dwarf galaxy Reticulum II was enriched by a rare and prolific r-process event, such as a neutron star merger. To investigate the nature of this event, we present high-resolution Magellan/MIKE spectroscopy of the brightest star in […]
Kavli Affiliate: Julia R. Greer | First 5 Authors: Xiaoyue Ni, Haolu Zhang, Danilo B. Liarte, Louis W. McFaul, Karin A. Dahmen | Summary: The transition from elastic to plastic deformation in crystalline metals shares history dependence and scale-invariant avalanche signature with other non-equilibrium systems under external loading: dilute colloidal suspensions, plastically-deformed amorphous solids, granular […]
Kavli Affiliate: Philip H. Scherrer | First 5 Authors: J. Todd Hoeksema, Charles S. Baldner, Rock I. Bush, Jesper Schou, Philip H. Scherrer | Summary: The Helioseismic and Magnetic Imager (HMI) instrument is a major component of NASA’s Solar Dynamics Observatory (SDO) spacecraft. Since beginning normal science operations on 1 May 2010, HMI has operated […]
Kavli Affiliate: Alyosha Molnar | First 5 Authors: Mayank Gupta, Arjun Jauhari, Kuldeep Kulkarni, Suren Jayasuriya, Alyosha Molnar | Summary: Light field imaging is limited in its computational processing demands of high sampling for both spatial and angular dimensions. Single-shot light field cameras sacrifice spatial resolution to sample angular viewpoints, typically by multiplexing incoming rays […]
Kavli Affiliate: Barbara Baird | First 5 Authors: Eshan D. Mitra, Samuel C. Whitehead, David Holowka, Barbara Baird, James P. Sethna | Summary: Lipid phase heterogeneity in the plasma membrane is thought to be crucial for many aspects of cell signaling, but the physical basis of participating membrane domains such as "lipid rafts" remains controversial.
