Kavli Affiliate: Kiyoshi W. Masui | First 5 Authors: The CHIME/FRB Collaboration, Bridget C. Andersen, Kevin Bandura, Mohit Bhardwaj, P. J. Boyle | Summary: The origin of fast radio bursts (FRBs), millisecond-duration flashes of radio waves that are visible at distances of billions of light-years, remains an open astrophysical question. Here we report the detection […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: D. Kandel, Roger W. Romani, Hongjun An, , | Summary: In a multi-orbit (100 ks) $mathrm{it XMM-Newton}$ exposure of the original black widow pulsar, PSR J1959+2048, we measure the strong orbital modulation caused by intrabinary shock (IBS) emission. The IBS light curve peak appears asymmetric, which […]
Kavli Affiliate: Ran Wang | First 5 Authors: , , , , | Summary: This paper develops a data-based approach to the closed-loop output feedback control of nonlinear dynamical systems with a partial nonlinear observation model. We propose an information state based approach to rigorously transform the partially observed problem into a fully observed problem […]
Kavli Affiliate: Jeffrey J. McMahon | First 5 Authors: Sumit Dahal, John W. Appel, Rahul Datta, Michael K. Brewer, Aamir Ali | Summary: The Cosmology Large Angular Scale Surveyor (CLASS) observes the polarized cosmic microwave background (CMB) over the angular scales of 1$^circ lesssim theta leq$ 90$^circ$ with the aim of characterizing primordial gravitational waves […]
Kavli Affiliate: Ke Wang | First 5 Authors: Jue Jiang, Weiwei Zhao, Fei Wang, Renzhong Du, Ludi Miao | Summary: When a ferromagnet is placed in contact with a superconductor, owing to incompatible spin order, the Cooper pairs from the superconductor cannot survive more than one or two nanometers inside the ferromagnet. This is confirmed […]
Kavli Affiliate: Peter W. Graham | First 5 Authors: William DeRocco, Peter W. Graham, Saarik Kalia, , | Summary: The axion is a well-motivated candidate for the inflaton, as the radiative corrections that spoil many single-field models are avoided by virtue of its shift symmetry. However, axions generically couple to gauge sectors. As the axion […]
Kavli Affiliate: Daniel Needleman | First 5 Authors: Stanislav Lukyanenko, Won-Dong Jang, Donglai Wei, Robbert Struyven, Yoon Kim | Summary: The developmental process of embryos follows a monotonic order. An embryo can progressively cleave from one cell to multiple cells and finally transform to morula and blastocyst. For time-lapse videos of embryos, most existing developmental […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Vir B. Bulchandani, Manas Kulkarni, Joel E. Moore, Xiangyu Cao, | Summary: We show that the quasiparticle kinetic theory for quantum and classical Calogero models reduces to the free-streaming Boltzmann equation. We reconcile this simple emergent behaviour with the strongly interacting character of the model by […]
Kavli Affiliate: Jonathan L. Rosner | First 5 Authors: Marek Karliner, Jonathan L. Rosner, , , | Summary: The BESIII Collaboration has observed a candidate for a $c bar c s bar u$ tetraquark $Z_{cs}$ at $(3982.5^{+1.8}_{-2.6} pm 2.1)$ MeV and width $(12.8^{+5.3}_{-4.4} pm 3.0)$ MeV, while the LHCb Collaboration has observed a $Z_{cs}$ candidate […]
Kavli Affiliate: Tom Melia | First 5 Authors: Andrew J. Larkoski, Tom Melia, , , | Summary: Despite being the overwhelming majority of events produced in hadron or heavy ion collisions, minimum bias events do not enjoy a robust first-principles theoretical description as their dynamics are dominated by low-energy quantum chromodynamics. In this paper, we […]
