Almost all Lagrangian torus orbits in are not Hamiltonian volume minimizing
Hiroshi Iriyeh, Hajime Ono
All principal orbits of the standard Hamiltonian -action on the complex projective space are Lagrangian tori.In this article, we prove that most of them are n…
Radioactive decay products in neutron star merger ejecta: heating efficiency and -ray emission
Kenta Hotokezaka, Shinya Wanajo, Masaomi Tanaka +3
The radioactive decay of the freshly synthesized -process nuclei ejected in compact binary mergers power optical/infrared macronovae (kilonovae) that follow these events. The li…
The Energy Spectrum of Cosmic Rays above 10 eV Measured by the Fluorescence Detectors of the Telescope Array Experiment in Seven Years
The Telescope Array Collaboration
The Telescope Array (TA) experiment is the largest detector to observe ultra-high-energy cosmic rays in the northern hemisphere. The fluorescence detectors at southern two stations…
Cohomology groups of homogeneous Poisson structures
Kentaro Mikami, Tadayoshi Mizutani
We generalize the notion of weight for Gelfan'd-Fuks cohomology theory of symplectic vector spaces to the homogeneous Poisson vector spaces, and try some combinatorial approach to…
Optical and Near-Infrared Polarimetry for a Highly Dormant Comet 209P/LINEAR
Daisuke Kuroda, Masateru Ishiguro, Makoto Watanabe +24
We conducted an optical and near-infrared polarimetric observation of the highly dormant Jupiter-Family Comet, 209P/LINEAR. Because of its low activity, we were able to determine t…
The Transient Accereting X-Ray Pulsar XTE J1946+274: Stability of the X-Ray Properties at Low Flux and Updated Orbital Solution
Diana M. Marcu-Cheatham, Katja Pottschmidt, Matthias Kühnel +19
We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J…
Fine-pitch semiconductor detector for the FOXSI mission
Shin-nosuke Ishikawa, Shinya Saito, Hiroyasu Tajima +11
The Focusing Optics X-ray Solar Imager (FOXSI) is a NASA sounding rocket mission which will study particle acceleration and coronal heating on the Sun through high sensitivity obse…
Construction of van der Waals magnetic tunnel junction using ferromagnetic layered dichalcogenide
Miho Arai, Rai Moriya, Naoto Yabuki +3
We investigate the micromechanical exfoliation and van der Waals (vdW) assembly of ferromagnetic layered dichalcogenide Fe0.25TaS2. The vdW interlayer coupling at the Fe-intercalat…
Duality-based calculations for transition probabilities in stochastic chemical reactions
Jun Ohkubo
An idea for evaluating transition probabilities in chemical reaction systems is proposed, which is efficient for repeated calculations with various rate constants. The idea is base…
New Identification of the Mixed-Morphology Supernova Remnant G298.6-0.0 with Possible Gamma-ray Association
Aya Bamba, Makoto Sawada, Yuto Nakano +4
We present an X-ray analysis on the Galactic supernova remnant (SNR) G298.6-0.0 with Suzaku. The X-ray image shows a center-filled structure inside the radio shell, implying this S…
Near-Infrared Polarimetry of the GG Tauri A Binary System
Yoichi Itoh, Yumiko Oasa, Tomoyuki Kudo +47
A high angular resolution near-infrared polarized-intensity image of the GG Tau A binary system was obtained with the Subaru Telescope. The image shows the circumbinary disk scatte…
Negative sign problem in continuous-time quantum Monte Carlo: optimal choice of single-particle basis for impurity problems
Hiroshi Shinaoka, Yusuke Nomura, Silke Biermann +2
The negative sign problem in quantum Monte Carlo (QMC) simulations of cluster impurity problems is the major bottleneck in cluster dynamical mean field calculations. In this paper…
Simulating Cherenkov Telescope Array observation of RX J1713.7-3946
T. Nakamori, H. Katagiri, H. Sano +29
We perform simulations of Cherenkov Telescope Array (CTA) observations of a young supernova remnant RX J1713.7-3946. This target is not only one of the brightest sources ever disco…
Emergence of charge degrees of freedom under high pressure in an organic dimer-Mott insulator -(BEDT-TTF)ICl
K. Hashimoto, R. Kobayashi, H. Okamura +7
To elucidate the pressure evolution of the electronic structure in an antiferromagnetic dimer-Mott (DM) insulator -(BEDT-TTF)ICl, which exhibits superconductivi…
Explicit biregular/birational geometry of affine threefolds: completions of A^3 into del Pezzo fibrations and Mori conic bundles
Adrien Dubouloz, Takashi Kishimoto
We study certain pencils of del Pezzo surfaces generated by a smooth del Pezzo surface S of degree less or equal to 3 anti-canonically embedded into a weighted projective space P a…
Stability of the Brascamp-Lieb constant and applications
Jonathan Bennett, Neal Bez, Taryn C. Flock +1
We prove that the best constant in the general Brascamp-Lieb inequality is a locally bounded function of the underlying linear transformations. As applications we deduce certain ve…
