Abstract

The research and training team of the Department of Astrophysics (DAP), Vietnam National Space Center, is some twenty years old. Currently, we work in the fields of stellar physics and high-redshift galaxies using mm/sub-mm data observed by world-leading radio interferometers such as ALMA and NOEMA. In this report, we present the research team and its activities and give illustrations of the research work with emphasis on the use of archival data.

Highlights

  • Department of Astrophysics (DAP), formerly Vietnam Astrophysics Training Laboratory (VATLY), hosts a research team that was put together twenty years ago by Professor Pierre Darriulat at the Institute for Nuclear Science and Technology in Hanoi

  • A particle physicist and Research Director of CERN (European Organization for Nuclear Research) he brought to Vietnam detectors and fast electronics units that had been used in particle physics experiments at CERN and had been given to him to help with the development of scientific research in the country

  • These contributed useful information for neutrino oscillation experiments such as Super-Kamiokande that need to map the muon flux on the Earth surface in order to model what they expect to detect. Both atmospheric muons and neutrinos are decay products of pions in the cascade of secondary particles produced by primary ultra-high energy cosmic rays coming from outer space: muons are tracers of neutrinos

Summary

Introduction

DAP, formerly Vietnam Astrophysics Training Laboratory (VATLY), hosts a research team that was put together twenty years ago by Professor Pierre Darriulat at the Institute for Nuclear Science and Technology in Hanoi. These contributed useful information for neutrino oscillation experiments such as Super-Kamiokande that need to map the muon flux on the Earth surface in order to model what they expect to detect Both atmospheric muons and neutrinos are decay products of pions in the cascade of secondary particles produced by primary ultra-high energy cosmic rays coming from outer space: muons are tracers of neutrinos. The subjects are in the fields of high red-shift galaxies, evolved stars and star formation respectively This way of supervising students is truly beneficial both for the PhD students and the whole team, in particular for a young research team like ours.
