Angling for x-ray pulsar geometry with polarimetry

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Victor Doroshenko, Juri Poutanen, Sergey Tsygankov, Valery Suleimanov, Matteo Bachetti | Summary: Using observations of X-ray pulsar Her X-1 by the Imaging X-ray Polarimetry Explorer, we report on a highly significant detection of the polarization signal from an accreting neutron star. The observed degree of the […]

Functional network properties derived from widefield calcium imaging differ with wakefulness and across cell type

Kavli Affiliate: Michael Crair | Authors: David O’Connor, Francesca Mandino, Xilin Shen, Corey Horien, Xinxin Ge, Peter Herman, Michael Crair, Xenophon Papademetris, Evelyn MR Lake and Robert Todd Constable | Summary: To improve bench-to-bedside translation, it is integral that knowledge flow bidirectionally from – animal models to humans, and vice versa. This will be facilitated […]

Possibilities and Limitations of Kinematically Identifying Stars from Accreted Ultra-Faint Dwarf Galaxies

Kavli Affiliate: Anna Frebel | First 5 Authors: Kaley Brauer, Hillary D. Andales, Alexander P. Ji, Anna Frebel, Mohammad K. Mardini | Summary: The Milky Way has accreted many ultra-faint dwarf galaxies (UFDs), and stars from these galaxies can be found throughout our Galaxy today. Studying these stars provides insight into galaxy formation and early […]

An entanglement perspective on the quantum approximate optimization algorithm

Kavli Affiliate: Joel E. Moore | First 5 Authors: Maxime Dupont, Nicolas Didier, Mark J. Hodson, Joel E. Moore, Matthew J. Reagor | Summary: Many quantum algorithms seek to output a specific bitstring solving the problem of interest–or a few if the solution is degenerate. It is the case for the quantum approximate optimization algorithm […]

ET White Paper: To Find the First Earth 2.0

Kavli Affiliate: Subo Dong | First 5 Authors: Jian Ge, Hui Zhang, Weicheng Zang, Hongping Deng, Shude Mao | Summary: We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time, the occurrence rate and the orbital distributions of Earth-sized […]
