Kavli Affiliate: Claude Canizares | Summary:X-ray absorption fine structure (XAFS) in the 0.2-2 keV band is a crucial component in multi-wavelength studies of dust mineralogy, size, and shape — parameters that are necessary for interpreting astronomical observations and building physical models across all fields, from cosmology to exoplanets. Despite its importance, many fundamental questions about […]
Kavli Affiliate: Rafe Schindler | Summary:We present new Gemini/GMOS optical spectroscopy of 16 extreme variability quasars (EVQs) that dimmed by more than 1.5 mag in the $g$ band between the Sloan Digital Sky Survey (SDSS) and the Dark Energy Survey (DES) epochs (separated by a few years in the quasar rest frame). The quasar sample […]
Kavli Affiliate: Naoshi Sugiyama | Summary:Neutral hydrogen (H$_rm I$) intensity mapping is capable of measuring redshift evolution of H$_rm I$ density parameter $Ω_rm H_rm I$, which is an important parameter to understand structure formation in the post-reionization epoch. Future H$_rm I$ observation with Square Kilometre Array (SKA) can significantly improve constraints on the parameter. However, […]
Kavli Affiliate: Graham Fleming | Summary:We investigate the spatial properties of sources from the GAIA catalogue previously identified as being members of the Taurus star forming region and which appear in the Spitzer catalogue. We study an area of sky of 10×15 deg, centred on Right Ascension (2000.0) = 68.5 deg and Declination (2000.0)= 27.0 […]
Kavli Affiliate: Richard Berry | Summary:The bacterial flagellar motor is an ion-powered transmembrane protein complex which drives swimming in many bacterial species. The motor consists of a cytoplasmic ‘rotor’ ring and a number of ‘stator’ units, which are bound to the cell wall of the bacterium. Recently, it has been shown that the number of […]
Kavli Affiliate: Eric Peng | First 5 Authors: The MSE Science Team, Carine Babusiaux, Maria Bergemann, Adam Burgasser, Sara Ellison | Summary: (Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unveil the composition and dynamics of the faint Universe and […]
Kavli Affiliate: Jin Suntivich | Summary:Electrides are ionic crystals in which the electrons prefer to occupy free space, serving as anions. Because the electrons prefer to be in the pockets, channels, or layers to the atomic orbitals around the nuclei, it has been challenging to find electrides with partially filled d-shells, since an unoccupied d-shell […]
Kavli Affiliate: Jin Suntivich | First 5 Authors: Padtaraporn Chanhom, Kevin E. Fritz, Lee Burton, Jan Kloppenburg, Yaroslav Filinchuk | Summary: Electrides are ionic crystals in which the electrons prefer to occupy free space, serving as anions. Because the electrons prefer to be in the pockets, channels, or layers to the atomic orbitals around the […]
Kavli Affiliate: Robert Rosner | Summary:We present a scheme by which a probabilistic forecasting system whose predictions have poor probabilistic calibration may be recalibrated by incorporating past performance information to produce a new forecasting system that is demonstrably superior to the original, in that one may use it to consistently win wagers against someone using […]
