II. Constitution

In the Asia-Pacific region, physicists are studying the universe in many ways, including：

1). Connecting theoretical models for the very early universe — cosmic inflation or an alternative scenario — with observable effects. Whatever happened in the first split-second after the Big Bang, it occurred while the universe was opaque to light, so physicists have to infer its properties indirectly. Some effects might show up in the CMB, while others might be visible in the large-scale structure of the universe. Inflation leaves an imprint on the fluctuations of mass and energy in the universe, which grow as spacetime expands.

2). Looking for signs of the first stars in the universe. These were likely much more massive than the average star around today, which made them unstable. The supernova explosions of these stars might be observable even that far away, either directly or indirectly through its effects on early galaxies.

3). Mapping the positions of galaxies to reconstruct the effects of dark energy. The Baryon Oscillation Survey in optical and radio wavelengths are ongoing projects to map baryon acoustic oscillations and understand the universe, from dark age, reionization to the acceleration.

4). Tracing the structure of galaxies as produced by dark matter, examining the dark matter property and also neutrino property through underground experiments. The next-generation Giant Magellan Telescope (GMT) and many underground experiments will provide a new realm for observing the effects of dark matter neutrinos.

5) Examining the exotic structure, the black hole and other compact stars in the universe. Black holes harbour some of the most remarkable predictions of General Relativity. The ground detection of gravitational waves marks a new era to test models of black hole formation, growth and evolution, models of gravitational-wave generation and propagation. Future gravitational wave observations on the ground and in the space will provide evidence for event horizons and ergoregions, test the theory of General Relativity, and may reveal the existence of new fundamental fields.

1) Pauchy Award: 
[Introduction]:
Woei-Yann Pauchy Hwang, a nuclear physicist turned cosmologist known for his significant contributions in weak interaction physics and in promoting physics research and education in Taiwan and the Asia-Pacific region, passed away in Taipei on May 6, 2018.
Pauchy led Taiwan’s astrophysics and high energy physics communities to establish the Center for Academic Excellence on Cosmology and Particle Astrophysics (CosPA). Further he launched the CosPA Symposia, in 2002, which, for the first time, provided a forum among cosmology and particle astrophysics colleagues in the Asia-Pacific region, now being held annually in different Asia-Pacific regions. Later the Asia-Pacific Organization for Cosmology and Particle Astrophysics (APCosPA.org) was established in 2011 and Pauchy was elected as its founding President (2011-2013).
Pauchy’s contribution to promoting physics in Asia-Pacific was unforgettable. He will be remembered as a remarkable physicist, a visionary leader and a devoted promoter of physics in the Asia-Pacific region. He lived up to the name he invented for himself, “Pauchy”, meaning “embracing misfortune” in Chinese. He will be dearly missed by all who had the good fortune to have known and worked with him.
Asia-Pacific Organization of Cosmology and Particle Astrophysics decided to establish “Pauchy Award” for the Promotion of Young Scientist start to select the winner in 2025.

[Selection Committee]:  Ming-Chung Chu （Coordinator）, Masahide Yamaguchi, Raymond Volkas, Chang Feng and Stefano Scopel.

[Selection Process]: 

[Benefactors]:  Sang Pyo Kim, Jen-Chieh Peng, Pauchy Hwang’s friends and family   


2) CosPA Awards:
CosPA awards were established to encourage young graduate students  in the research field of Gravitation, Cosmology and Particle-Astrophysics.

[Selection Committee and Selection Process]:  Chosen by the organization committee of each CosPA symposium

[Benefactors]:  Local organizer of each CosPA symposium

2) Call for application for Pauchy Award and CosPA Award


 

1) Scope:
Cosmology and astroparticle physics are some of the most active and inspiring areas of the physical sciences. The Asia-Pacific Organization of Cosmology and Particle Astrophysics promotes a common goal as APCTP, ‘development of fundamental physics research in the Asia-Pacific region’ in cooperation with member countries and regions and partner institutes. The AP CosPA Org focuses on advancing the research in cosmology and particle astrophysics, contributes to the human understanding of the universe.
