  • Dark matter from the inert Higgs doublet model 
    Treesukrat W.; Uttayarat P. (2019)
    Dark matter is a clear evidence of new physics beyond the Standard Model. In this work, we consider the inert doublet model where dark matter is a member of a new Higgs doublet. In this scenario, dark matter properties can ...
  • Effects of hydrogen peroxide on 304 stainless steel in high temperature water 
    Makjan S.; Boonsri P.; Channuie J.; Kanjana K. (2019)
    Hydrogen peroxide (H2O2), an oxidizer produced by water radiolysis, is considered one of the main contributors to corrosion of the stainless steel (SS) components in the cooling system of nuclear reactors. The detailed ...
  • Reverberation mapping of the disc wind in ultraluminous X-ray source NGC 5408 X-1 
    Loekkesee S.; Chainakun P.; Luangtip W. (2019)
    Recent observational evidences suggested that ultraluminous X-ray sources (ULXs) which are in supercritical accretion rate might release the outflowing wind and change the geometry to slim disc. However, the exact structure ...
  • Searching for the electron/positron pair halo of the Blazar H1426+428 using XMM-Newton 
    Kueathan A.; Luangtip W.; Eungwanichayapant A. (2019)
    Electron/positron pair halo is a physical phenomenon in which the very high energy gamma rays emitted from Blazar interact with cosmic infrared background (CIB) so that produce the electron/positron pairs; the produced ...
  • Thai national telescope studies of ultraluminous X-ray sources 
    Thongpoyai K.; Luangtip W.; Sawangwit U.; Roberts T.P.; Komonjinda S.; Dhillon V.S.; Marsh T.R. (2019)
    Ultraluminous X-ray sources (ULXs) are extra-galactic, non-nuclear sources with X-ray luminosity in excess of 1039 erg s-1. It has been thought that the majority of ULX populations are stellar-mass objects accreting matter ...
  • Two conserved angular momenta in schwarzschild spacetime geodesics 
    Musiri S. (2019)
    The present study investigated the geodesic paths in the 3+1 dimensional Schwarzschild spacetime. Four conserved parameters were found: The first is the conserved total energy: The second is the coordinate-invariant metrics: ...
