  • Development of a digital zenith telescope for advanced astrometry 
    Hanada H.; Araki H.; Tazawa S.; Tsuruta S.; Noda H.; Asari K.; Sasaki S.; Funazaki K.; Satoh A.; Taniguchi H.; Kikuchi M.; Takahashi T.; Yamazaki A.; Ping J.; Kawano N.; Petrova N.; Gouda N.; Yano T.; Yamada Y.; Niwa Y.; Kono Y.; Iwata T. (2012)
    Like other optical astrometric techniques, the Photographic Zenith Tube (PZT) has played a key role in the past observations of the Earth rotation, and it also has a potential to be applied to several other observations ...
  • Development of a small telescope like PZT and effects of vibrations of mercury surface and ground noise 
    Hanada H.; Tsuruta S.; Asari K.; Araki H.; Noda H.; Tazawa S.; Kashima S.; Funazaki K.; Satoh A.; Taniguchi H.; Kato H.; Kikuchi M.; Sasaki H.; Hasegawa T.; Yano T.; Gouda N.; Kobayashi Y.; Yamada Y.; Iwata T.; Gusev A. (2017)
    © 2017, Pleiades Publishing, Ltd. A PZT type telescope for observations of gravity gradient and lunar rotation was developed, and a Bread Board Model (BBM) for ground experiments was completed. Some developments were made ...
  • Differential VLBI observations of two sub-satellites of SELENE (KAGUYA), OKINA and OUNA for lunar gravimetry 
    Hanada H.; Iwata T.; Kikuchi F.; Liu Q.; Matsumoto K.; Asari K.; Ishikawa T.; Ishihara Y.; Noda H.; Tsuruta S.; Petrova N.; Goossens S.; Harada Y.; Sasaki S.; Namiki N.; Kono Y.; Iwadate K.; Kameya O.; Jike T.; Shibata K.; Tamura Y.; Yahagi Y.; Masui W.; Tanaka K.; Maejima H.; Hong X.; Ping J.; Aili Y.; Ellingsen S.; Schlüter W. (2009)
    The Japanese lunar explorer SELENE (KAGUYA), which has been launched on Sep. 14th, 2007, utilizes VLBI observations in lunar gravimetry investigations. This can particularly improve the accuracy of the low degree gravitational ...
  • Direct guanylation of amino groups by cyanamide in water: Catalytic generation and activation of unsubstituted carbodiimide by scandium(iii) triflate 
    Tsubokura K.; Iwata T.; Taichi M.; Kurbangalieva A.; Fukase K.; Nakao Y.; Tanaka K. (2014)
    Guanylation proceeded efficiently upon treatment of the various amines with cyanamide in the presence of catalytic amounts of scandium(III) triflate under mild conditions. The method did not require the guanylation reagents ...
  • One-Pot Evolution of Ageladine A through a Bio-Inspired Cascade towards Selective Modulators of Neuronal Differentiation 
    Iwata T.; Otsuka S.; Tsubokura K.; Kurbangalieva A.; Arai D.; Fukase K.; Nakao Y.; Tanaka K. (2016)
    © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, WeinheimA bio-inspired cascade reaction has been developed for the construction of the marine natural product ageladine A and a de novo array of its N1-substituted derivatives. ...
  • Overview of differential VLBI observations of lunar orbiters in SELENE (Kaguya) for precise orbit determination and lunar gravity field study 
    Hanada H.; Iwata T.; Liu Q.; Kikuchi F.; Matsumoto K.; Goossens S.; Harada Y.; Asari K.; Ishikawa T.; Ishihara Y.; Noda H.; Tsuruta S.; Petrova N.; Kawano N.; Sasaki S.; Sato K.; Namiki N.; Kono Y.; Iwadate K.; Kameya O.; Shibata K.; Tamura Y.; Kamata S.; Yahagi Y.; Masui W.; Tanaka K.; Maejima H.; Hong X.; Ping J.; Shi X.; Huang Q.; Aili Y.; Ellingsen S.; Schlüter W. (2010)
    The Japanese lunar explorer SELENE (Kaguya), which was launched on September 14th, 2007, was the target of VLBI observations over the period November 2007 to June 2009. These observations were made in order to improve the ...
  • Picosecond accuracy VLBI of the two subsatellites of SELENE (KAGUYA) using multifrequency and same beam methods 
    Kikuchi F.; Liu Q.; Hanada H.; Kawano N.; Matsumoto K.; Iwata T.; Goossens S.; Asari K.; Ishihara Y.; Tsuruta S.; Ishikawa T.; Noda H.; Namiki N.; Petrova N.; Harada Y.; Ping J.; Sasaki S. (2009)
    Same beam very long baseline interferometry (VLBI) observations of the two subsatellites of SELENE (KAGUYA) are demonstrated for purpose of the precise gravimetry of the Moon. Same beam VLBI contributes a great deal to ...
