The study of the flux, spectrum, and directional distribution of cosmic rays arriving to Earth provides unique information in the fields of Astrophysics and Space Physics. At energies above $\sim 1\,$GeV, the best way to study cosmic rays is by detecting, at ground level, the secondary particles produced by cosmic rays in the atmosphere, including neutrons. One standard type of neutron...
Solar and lunar eclipses are astronomical phenomena which is an excellent topic for introducing astronomy to primary school students. We have used Minecraft which is a popular game about placing blocks to construct anything and can make a simple model of the Sun, Moon and Earth easily. The background knowledge of Pratom 6 students (grade 6) has already had about the position of them on Earth...
We present BV Photometry for the globular clusters (GCs) M3 (NGC 5272), M 92(NGC 6341) and M107 (NGC 6171), which are analyzed by Aperture Photometry Tool (APT). All of optical images were taken by 2.4m Telescope at Thai National Observatory in Chiang Mai, Thailand. The magnitudes of stars in three globular clusters were determined. Furthermore, the luminosity of each star was converted based...
We study the prediction of the gamma ray signal generated from Galactic halo dark matter (DM) annihilation. The study focuses on the electron and positron pair production resulting from self-conjugate dark matter particles. We use Milky Way (MW) DM density profile measurement from literatures which are fitted with NFW, Burkett and Einasto models. The most important radiative process in the...
We have analyzed photometric and spectroscopic data of HE0345+0056 which is an AGN in our ongoing variability monitoring program. Our well defined parent quasar sample is drawn from the Hamburg/ESO survey and observed in several broad- (B,V,R) and narrow-band filters with the Thai Robotic telescope in Chile.Our aim is to use photometric reverberation mapping techniques to study the BLR of...
Jupiter is the most gigantic planet in the solar system and yet, generating the most intense and enormous magnetosphere. VIPAL magnetic field model is chosen to simulate Jupiter’s magnetic field model. VIPAL was constructed based on observations by Pioneer and Voyager spacecrafts. This model appears to have a lot of benefits. For example, it can be used to analyze auroral emission in Jupiter’s...
