Population gradient in Sextans dSph: Comprehensive mapping of a dwarf galaxy by Suprime-Cam
S. Okamoto, N. Arimoto, E. Tolstoy +5
We present the deep and wide and photometry of the Sextans dwarf spheroidal galaxy (dSph) taken by Suprime-Cam imager on the Subaru Telescope, which extends out to the ti…
Observation of thundercloud-related gamma rays and neutrons in Tibet
H. Tsuchiya, K. Hibino, K. Kawata +19
During the 2010 rainy season in Yangbajing (4300 m above sea level) in Tibet, China, a long-duration count enhancement associated with thunderclouds was detected by a solar neutron…
Upper limits on the solar-neutron flux at the Yangbajing neutron monitor from BATSE-detected solar flares
H. Tsuchiya, H. Miyasaka, E. Takahashi +11
The purpose of this work is to search the Yangbajing neutron monitor data obtained between 1998 October and 2000 June for solar neutrons associated with solar flares. Using the ons…
Stellar Populations of Elliptical Galaxies in Virgo Cluster I. : The Data and Stellar Population Analysis
Y. Yamada, N. Arimoto, A. Vazdekis +1
We have determined spectroscopic ages of elliptical galaxies in the Virgo cluster using spectra of very high signal-to-noise ratio (S/N/A > 100). We observed 8 galaxies with the Su…
