Kavli Affiliate: George Efstathiou | First 5 Authors: George Efstathiou, Steven Gratton, , , | Summary: We revisit the observational constraints on spatial curvature following recent claims that the Planck data favour a closed Universe. We use a new and statistically powerful Planck likelihood to show that the Planck temperature and polarization spectra are consistent […]
Kavli Affiliate: Maria Elena Monzani | First 5 Authors: Venkitesh Ayyar, Wahid Bhimji, Maria Elena Monzani, Andrew Naylor, Simon Patton | Summary: High Energy Physics experiments like the LUX-ZEPLIN dark matter experiment face unique challenges when running their computation on High Performance Computing resources. In this paper, we describe some strategies to optimize memory usage […]
Kavli Affiliate: Eric Charles | First 5 Authors: Ke Fang, Arka Banerjee, Eric Charles, Yuuki Omori, | Summary: The origin of the bulk of the astrophysical neutrinos detected by the IceCube Observatory remains a mystery. Previous source-finding analyses compare the directions of IceCube events and individual sources in astrophysical catalogs. The source association method is […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Zack Li, Sigurd Naess, Simone Aiola, David Alonso, John W. Appel | Summary: One of the most important checks for systematic errors in CMB studies is the cross correlation of maps made by independent experiments. In this paper we report on the cross correlation between maps from […]
Kavli Affiliate: Angela Olinto | First 5 Authors: Martin Elvis, Jon Arenberg, David Ballantyne, Mark Bautz, Charles Beichman | Summary: Astrophysics spans an enormous range of questions on scales from individual planets to the entire cosmos. To address the richness of 21st century astrophysics requires a corresponding richness of telescopes spanning all bands and all […]
Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: Emanuele Castorina, Simon Foreman, Dionysios Karagiannis, Adrian Liu, Kiyoshi W. Masui | Summary: The Packed Ultra-wideband Mapping Array (PUMA) is a proposed low-resolution transit interferometric radio telescope operating over the frequency range 200 – 1100MHz. Its rich science portfolio will include measuring structure in the universe […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Shun-ichi Horigome, Kohei Hayashi, Masahiro Ibe, Miho N. Ishigaki, Shigeki Matsumoto | Summary: Dwarf spheroidal galaxies (dSphs) are promising targets of indirect detection experiments searching for dark matter (DM) at present universe. Toward robust prediction for the amount of signal flux originating in DM annihilation inside dSphs, […]
Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Josue Rodriguez, Gilbert Lopez, Samantha Crouch, Nicholas P. Breznay, Robert Kealhofer | Summary: Spin orbit assisted Mott insulators such as sodium iridate (Na$_2$IrO$_3$) have been an important subject of study in the recent years. In these materials, the interplay of electronic correlations, spin-orbit coupling, crystal field effects […]
Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Dacheng Lin, Jay Strader, Aaron J. Romanowsky, Jimmy A. Irwin, Olivier Godet | Summary: We recently discovered the X-ray/optical outbursting source 3XMM J215022.4-055108. It was best explained as the tidal disruption of a star by an intermediate-mass black hole of mass of a few tens of […]
Kavli Affiliate: Clarence Chang | First 5 Authors: Changjiang Liu, Vincent F. C. Humbert, Terence Bretz-Sullivan, Gensheng Wang, Deshun Hong | Summary: Amongst the rare-earth perovskite nickelates, LaNiO$_3$ (LNO) is an exception. While the former have insulating and antiferromagnetic ground states, LNO remains metallic and non-magnetic down to the lowest temperatures. It is believed that […]
