Kavli Affiliate: Philip H. Scherrer | First 5 Authors: M. Cristina Rabello-Soares, Richard S. Bogart, Philip H. Scherrer, , | Summary: We analyze the effect of a sunspot in its quiet surroundings applying a helioseismic technique on almost three years of Helioseismic and Magnetic Imager (HMI) observations obtained during solar cycle 24 to further study […]
Kavli Affiliate: Stuart Marshall | First 5 Authors: Alastair Murray, Stuart Marshall, Leroy Cronin, , | Summary: How do we estimate the probability of an abundant objects’ formation, with minimal context or assumption about is origin? To explore this we have previously introduced the concept of pathway assembly (as pathway complexity), in a graph based […]
Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: It is suggested that the exact value of the cosmological constant could be derived from first principles, based on entanglement of the Standard Model field vacuum with emergent holographic quantum geometry. For the observed value of the cosmological constant, geometrical […]

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: 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: Mikhail Kapranov | First 5 Authors: Michael Finkelberg, Mikhail Kapranov, Vadim Schechtman, , | Summary: We consider the category of perverse sheaves on a complex vector space smooth with respect to a stratification given by an arrangement of hyperplanes with real equations. As shown in an earlier wotk of two of the authors, […]
Kavli Affiliate: Maria T. Zuber | First 5 Authors: Christopher E. Carr, Noelle C. Bryan, Kendall N. Saboda, Srinivasa A. Bhattaru, Gary Ruvkun | Summary: Parabolic flights provide cost-effective, time-limited access to "weightless" or reduced gravity conditions experienced in space or on planetary surfaces, e.g. the Moon or Mars. These flights facilitate fundamental research – […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Gordan Krnjaic, , , , | Summary: Freeze-in dark matter (DM) mediated by a light ($ll$ keV) weakly-coupled dark-photon is an important benchmark for the emerging low-mass direct detection program. Since this is one of the only predictive, detectable freeze-in models, we investigate how robustly such testability […]
Kavli Affiliate: Tadashi Orita | First 5 Authors: Shin-nosuke Ishikawa, Tadayuki Takahashi, Shin Watanabe, Noriyuki Narukage, Satoshi Miyazaki | Summary: We have developed a system combining a back-illuminated Complementary-Metal-Oxide-Semiconductor (CMOS) imaging sensor and Xilinx Zynq System-on-Chip (SoC) device for a soft X-ray (0.5-10 keV) imaging spectroscopy observation of the Sun to investigate the dynamics of […]
