Kavli Affiliate: Rodriguez Enrique Lopez | Summary:We report on polarimetric maps made with HAWC+/SOFIA toward Rho Oph A, the densest portion of the Rho Ophiuchi molecular complex. We employed HAWC+ bands C (89 $μ$m) and D (154 $μ$m). The slope of the polarization spectrum was investigated by defining the quantity R_DC = p_D/p_C, where p_C […]
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: 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: 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 […]
Kavli Affiliate: Philip H. Scherrer| First 5 Authors: P. H. Scherrer, P. H. Scherrer, , , | Summary:Fossat et al. (2017) recently reported detecting rotational splitting of g modes indirectly via the interaction with p modes observed directly by the GOLF instrument on SOHO. They concluded that the core of the Sun is rotating 3:8 […]
Kavli Affiliate: Hiroaki Aihara | Summary:We present the first measurement of cross-correlation between the lensing potential, reconstructed from cosmic microwave background (CMB) it polarization data, and the cosmic shear field from galaxy shapes. This measurement is made using data from the POLARBEAR CMB experiment and the Subaru Hyper Suprime-Cam (HSC) survey. By analyzing an 11~deg$^2$ […]
Kavli Affiliate: Rob Simcoe | First 5 Authors: Mansi M. Kasliwal, Scott Adams, Igor Andreoni, Michael Ashley, Nadia Blagorodnova | Summary: Opening up the dynamic infrared sky for systematic time-domain exploration would yield many scientific advances. Multi-messenger pursuits such as localizing gravitational waves from neutron star mergers and quantifying the nucleosynthetic yields require the infrared. […]
