Kavli Affiliate: Claudio Ricci | First 5 Authors: Arghajit Jana, Neeraj Kumari, Prantik Nandi, Sachindra Naik, Arka Chatterjee | Summary: We study the nature of the changing-look Active Galactic Nucleus NGC 1566 during its June 2018 outburst. During the outburst, the X-ray intensity of the source rises up to ~25-30 times compared to its quiescent […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Satoshi Yamada, Yoshihiro Ueda, Atsushi Tanimoto, Masatoshi Imanishi, Yoshiki Toba | Summary: We perform a systematic X-ray spectroscopic analysis of 57 local ultra/luminous infrared galaxy systems (containing 84 individual galaxies) observed with Nuclear Spectroscopic Telescope Array and/or Swift/BAT. Combining soft X-ray data obtained with Chandra, XMM-Newton, Suzaku […]
Kavli Affiliate: Gregory Herczeg | First 5 Authors: Wooseok Park, Jeong-Eun Lee, Carlos Contreras Peña, Doug Johnstone, Gregory Herczeg | Summary: Variability in young stellar objects (YSOs) can be caused by various time-dependent phenomena associated with star formation, including accretion rates, geometric changes in the circumstellar disks, stochastic hydromagnetic interactions between stellar surfaces and inner […]
Kavli Affiliate: Gregory Herczeg | First 5 Authors: Yong-Hee Lee, Doug Johnstone, Jeong-Eun Lee, Gregory Herczeg, Steve Mairs | Summary: We present the four-year survey results of monthly submillimeter monitoring of eight nearby ($< 500 $pc) star-forming regions by the JCMT Transient Survey. We apply the Lomb-Scargle Periodogram technique to search for and characterize variability […]
Kavli Affiliate: Subo Dong | First 5 Authors: Di-Chang Chen, Jia-Yi Yang, Ji-Wei Xie, Ji-Lin Zhou, Subo Dong | Summary: The Kepler telescope has discovered over 4,000 planets (candidates) by searching ? 200,000 stars over a wide range of distance (order of kpc) in our Galaxy. Characterizing the kinematic properties (e.g., Galactic component membership and […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Nicole Arulanantham, Kevin France, Keri Hoadley, P. C. Schneider, Catherine C. Espaillat | Summary: Ultraviolet spectra of protoplanetary disks trace distributions of warm gas at radii where rocky planets form. We combine HST-COS observations of H2 and CO emission from 12 classical T Tauri stars to […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Manuel Arca Sedda, Stanislav Babak, Christopher P. L. Berry, Emanuele Berti | Summary: The science objectives of the LISA mission have been defined under the implicit assumption of a 4 yr continuous data stream. Based on the performance of LISA Pathfinder, it is […]
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: 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: Renxin Xu | First 5 Authors: Tingting Lin, Shuang Du, Renxin Xu, , | Summary: Magnetic field may distort neutron stars (NSs), but the effect has not been robustly tested through gravitational-wave observation yet due to the absence of a fast rotating Galactic magnetar. The central objects of Gamma-ray bursts (GRBs) could be […]
