The Exoplanet Mass-Ratio Function from the MOA-II Survey: Discovery of a Break and Likely Peak at a Neptune Mass
D. Suzuki, D. P. Bennett, T. Sumi +26
We report the results of the statistical analysis of planetary signals discovered in MOA-II microlensing survey alert system events from 2007 to 2012. We determine the survey sensi…
Faint source star planetary microlensing: the discovery of the cold gas giant planet OGLE-2014-BLG-0676Lb
N. J. Rattenbury, D. P. Bennett, T. Sumi +85
We report the discovery of a planet --- OGLE-2014-BLG-0676Lb --- via gravitational microlensing. Observations for the lensing event were made by the MOA, OGLE, Wise, RoboNET/LCOGT,…
Topological defects in open string field theory
Toshiko Kojita, Carlo Maccaferri, Toru Masuda +1
We show how conformal field theory topological defects can relate solutions of open string field theory for different boundary conditions. To this end we generalize the results of…
Chemical evolution of the Universe at 0.7 < z < 1.6 derived from abundance diagnostics of the broad-line region of quasars
Hiroaki Sameshima, Yuzuru Yoshii, Kimiaki Kawara
We present an analysis of Mg II and Fe II UV emission lines for archival Sloan Digital Sky Survey (SDSS) quasars to explore diagnostics of the magnesium-to-iron abund…
Correlation effect in SrLaRuO studied by soft x-ray photoemission spectroscopy
Ikuto Kawasaki, Yumi Sakon, Shin-ichi Fujimori +3
To clarify how the electronic state of Sr1-xLaxRuO3 evolves with La doping, we conducted photoemission (PES) experiments using soft x-rays. The spectral shape of the Ru 4d derived…
J-GEM Follow-Up Observations of The Gravitational Wave Source GW151226
Michitoshi Yoshida, Yousuke Utsumi, Nozomu Tominaga +35
We report the results of optical--infrared follow-up observations of the gravitational wave (GW) event GW151226 detected by the Advanced LIGO in the framework of J-GEM (Japanese co…
