Research Interests

Studies of variable/transient sources

• Study of Galactic Plane radio variable sources
• Millimeter monitoring of X-ray binaries (CygX-3, SS433, LSI+61303, GRS1915+105)
• Variability study of Sgr A* at millimeter (+submillimeter)
  • Poster presented at IAU 303 "The Galactic Center: Feeding & Feedback in a Normal Galactic Nucleus" 2013 Sep30 - Oct4, Santa Fe New Mexico (pdf)
• GRBs

Other collaborations

• Study of vicinity of SgrA* using ALMA
• Study of galaxy clusters using Sunyaev-Zel'dovich Effect

Imaging simulations

• ACA simulations using GILDAS ALMA simulator
  ALMA Memo #488.1 "Wide-Field Imaging of ALMA with the Atacama Compact Array: Imaging Simulations"
• Also partly collaborated on ALMA imaging simulations of Sunyaev-Zel'dovich Effect (see Yamada et al. 2012, PASJ 64,102)

Software development

Current

• CASA
  Some of the stuffs that I am (or was) responsible for:
  • imaging
    • involving in imager refactor
    • clean mask handling including autoboxing
    • spectral line data cube handling: spectral coordinates, parallelization
    • task interface development for sdint (sdintimaging)
  • setjy
    • Updating JPL-Horizon ephemeris tables
    • Flux Standards Restructure
  • verification testing
  (OLD) other development references
