Kavli Affiliate: W. L. Kimmy Wu | First 5 Authors: Dominic Beck, Ari Cukierman, W. L. Kimmy Wu, , | Summary: We investigate simulation-based bandpower covariance matrices commonly used in cosmological parameter inferences such as the estimation of the tensor-to-scalar ratio $r$. We find that upper limits on $r$ can be biased low by tens […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Robert T. Zellem, Bijan Nemati, Vanessa P. Bailey, Eric J. Cady, M. Mark Colavita | Summary: NASA’s next flagship mission, the Nancy Grace Roman Space Telescope, is a 2.4-meter observatory set to launch no later than May 2027. Roman features two instruments: the Wide Field Imager and […]
Kavli Affiliate: R. Morris | First 5 Authors: Jun-Hui Zhao, Mark R. Morris, W. M. Goss, , | Summary: Using the JVLA, we explored the Galactic center (GC) with a resolution of 0.05" at 33.0 and 44.6 GHz. We detected 64 hyper-compact radio sources (HCRs) in the central parsec. The dense group of HCRs can […]
Kavli Affiliate: R. Morris | First 5 Authors: J. R. Morris, , , , | Summary: Energy minimizing BPS equations and solutions are obtained for a class of models in Maxwell-scalar theory, where an abelian electric charge is immersed in an effective dielectric of a real scalar field. The first order BPS equations are developed […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Martijn de Vries, Roger W. Romani, , , | Summary: New X-ray and optical observations shed light on the remarkable X-ray filament of the Gamma-ray pulsar PSR~J2030+4415. Images of the associated H$alpha$ bow shock’s evolution over the past decade compared with its velocity structure provide an […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: LiteBIRD Collaboration, E. Allys, K. Arnold, J. Aumont, R. Aurlien | Summary: LiteBIRD, the Lite (Light) satellite for the study of B-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission for primordial cosmology and fundamental physics. The Japan Aerospace Exploration Agency (JAXA) […]
Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Shamganth Kumarapandian, Qasim Zeeshan Ahmed, Faheem A. Khan, , | Summary: Device-to-device (D2D) or Sidelink aided communication is regarded as one of the most promising technologies to improve the spectral efficiency of the 5G and beyond communication system. However, two main challenges exist: 1) the selection of […]
Kavli Affiliate: Sven Herrmann | First 5 Authors: Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer, Peter F. Barker, Angelo Bassi | Summary: The objective of the proposed MAQRO mission is to harness space for achieving long free-fall times, extreme vacuum, nano-gravity, and cryogenic temperatures to test the foundations of physics in macroscopic quantum experiments. This will […]
Kavli Affiliate: C. L. Kuo | First 5 Authors: P. M. Chichura, A. Foster, C. Patel, N. Ossa-Jaen, P. A. R. Ade | Summary: We present the first measurements of asteroids in millimeter wavelength (mm) data from the South Pole Telescope (SPT), which is used primarily to study the cosmic microwave background (CMB). We analyze […]
Kavli Affiliate: Steven Allen | First 5 Authors: Eric D. Miller, Catherine E. Grant, Marshall W. Bautz, Silvano Molendi, Ralph Kraft | Summary: The Wide Field Imager (WFI) flying on Athena will usher in the next era of studying the hot and energetic Universe. WFI observations of faint, diffuse sources will be limited by uncertainty […]
