Kavli Affiliate: Susan E. Clark | First 5 Authors: Enrique Lopez-Rodriguez, Rainer Beck, Susan E. Clark, Annie Hughes, Alejandro S. Borlaff | Summary: Galactic bars are frequent in disk galaxies and they may support the transfer of matter towards the central engine of active nuclei. The barred galaxy NGC 1097 has magnetic forces controlling the […]
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 […]
