Kavli Affiliate: Robert Cameron | First 5 Authors: Mayukh Panja, Robert Cameron, Sami K. Solanki, , | Summary: There are no direct spatially resolved observations of spots on stars other than the Sun and starspot properties are inferred indirectly through lightcurves and spectropolarimetric data. We present the first self-consistent 3D radiative MHD computations of starspots […]
Kavli Affiliate: Shawn Henderson | First 5 Authors: Mayuri Sathyanarayana Rao, Maximiliano Silva-Feaver, Aamir Ali, Kam Arnold, Peter Ashton | Summary: The Simons Observatory (SO) is an upcoming polarization-sensitive Cosmic Microwave Background (CMB) experiment on the Cerro Toco Plateau (Chile) with large overlap with other optical and infrared surveys (e.g., DESI, LSST, HSC). To enable […]
Kavli Affiliate: Brian Lantz | First 5 Authors: Michael P. Ross, Krishna Venkateswara, Conor Mow-Lowry, Sam Cooper, Jim Warner | Summary: Modern gravitational-wave observatories require robust low-frequency active seismic isolation in order to keep the interferometer at its ideal operating conditions. Seismometers are used to measure both the motion of the ground and isolated platform. […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Noah Kurinsky, Daniel Baxter, Yonatan Kahn, Gordan Krnjaic, Peter Abbamonte | Summary: We respond to Robinson and Michaud’s (RM) comment (arXiv:2002.08893) on our recent preprint arXiv:2002.06937, in which we discuss recent excesses in low-threshold dark matter searches, and offer a potential unifying dark matter interpretation. We thank […]
Kavli Affiliate: Roger Blandford | First 5 Authors: Roger Blandford, Jo Dunkley, Carlos Frenk, Ofer Lahav, Alice Shapley | Summary: Cosmology now has a standard model – a remarkably simple description of the universe, its contents and its history. A symposium held last September in Cambridge, UK, gave this model a ‘health check’ and discussed […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, , , | Summary: We present a model for atmospheric wind circulation in binary millisecond pulsar (MSP) companions, showing how the optical light curve (LC) and radial velocities (RV) are sensitive to the wind flow, causing LC orbital phase shifts and […]
Kavli Affiliate: Eli Rykoff | First 5 Authors: DES Collaboration, Tim Abbott, Michel Aguena, Alex Alarcon, Sahar Allam | Summary: We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same shear and source photometric redshifts […]
Kavli Affiliate: Roger D. Blandford | First 5 Authors: Noemie Globus, Roger D. Blandford, , , | Summary: Biological molecules chose one of two structurally, chiral systems which are related by reflection in a mirror. It is proposed that this choice was made, causally, by magnetically polarized and physically chiral cosmic-rays, which are known to […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Hao Chen, Rupak Mahapatra, Glenn Agnolet, Michael Nippe, Minjie Lu | Summary: The detection of a single quantum of energy with high efficiency and low false positive rate is of considerable scientific interest, from serving as single quantum sensors of optical and infra-red photons to enabling the […]
Kavli Affiliate: Noah Kurinsky | First 5 Authors: , , , , | Summary: We present a novel unifying interpretation of excess event rates observed in several dark matter direct-detection experiments that utilize single-electron threshold semiconductor detectors. Despite their different locations, exposures, readout techniques, detector composition, and operating depths, these experiments all observe statistically significant […]
