  16. ZARAH DAN DAYA 2017, UNIVERSITI MALAYA, 26TH DECEMBER 2017 NEAR FUTURE • East Asia Observatory (EAO) • Establishing Malaysia as “Observer” status; with UM as main contact point • EAO operates the 15-m JCMT and Subaru Telescope (optical and near IR astronomy), and Submillimetre Array SMA (eight 6-meter radio telescopes array)

  17. ZARAH DAN DAYA 2017, UNIVERSITI MALAYA, 26TH DECEMBER 2017 EAST ASIA OBSERVATORY • The East Asian Observatory (EAO) is incorporated by the East Asian Core Observatories Organization (EACOA) for the purpose of pursuing joint projects in astronomy within the East Asian region. • The EACOA consists of • Academia Sinica Institute of Astronomy and Astrophysics (ASIAA), Taiwan • Korea Astronomy and Space Science Institute (KASI), Korea • National Astronomical Observatories, Chinese Academy of Sciences (NAOC), China • National Astronomical Observatory of Japan (NAOJ), Japan

  18. ZARAH DAN DAYA 2017, UNIVERSITI MALAYA, 26TH DECEMBER 2017 EAST ASIA OBSERVATORY • The EAO currently operates the James Clerk Maxwell Telescope (JCMT), which is the largest single dish telescope designed to operate at submillimeter wavelengths (from 1987) at 215-680 GHz. • The 15 meter telescope is located on the summit of Hawaii’s Mauna Kea.

  19. ZARAH DAN DAYA 2017, UNIVERSITI MALAYA, 26TH DECEMBER 2017 EAST ASIA OBSERVATORY • The EAO currently operates the James Clerk Maxwell Telescope (JCMT), which is the largest single dish telescope designed to operate at submillimeter wavelengths (from 1987) at 215-680 GHz. • The 15 meter telescope is located on the summit of Hawaii’s Mauna Kea. • The JCMT was once owned by the UK Science and Technology Facilities Council (STFC) and was supported by the National Research Council (NRC) of Canada. • The STFC and NRC have withdrawn funding from the JCMT with effect from 15 th January 2015, and ownership of JCMT has been transferred to the University of Hawaii. • The EAO operates JCMT on behalf of the University of Hawaii since the 1 st March 2015.

  20. ZARAH DAN DAYA 2017, UNIVERSITI MALAYA, 26TH DECEMBER 2017 EAST ASIA OBSERVATORY • In 2017, the EAO began to share in the access of the Subaru Telescope, which is the 8.3m national optical telescope of Japan operated by NAOJ on the summit of Mauna Kea. • In 2017, the EAO also began to share in the access of the Submillimeter Array, which is an 8-element radio interferometer operated by ASIAA and the Smithsonian Astrophysical Observatory also on Mauna Kea. • On 3rd July 2017, EAO began discussions with UM to incorporate Malaysia as EAO “observer” • Malaysia will be given free access to EAO supported instruments • Malaysia will be considered for observation time • Malaysia will have open access to all EAO survey programs

  21. ZARAH DAN DAYA 2017, UNIVERSITI MALAYA, 26TH DECEMBER 2017 SCIENCE WITH EAST ASIA OBSERVATORY • The submillimetre waveband provides a unique window on the most active phases of galaxy formation in the distant universe. • The most actively star-forming galaxies, at all redshifts, are highly obscured by dust and as a result are bright far-infrared sources. • Such systems are cosmologically important as they host a large fraction of the total star formation at high redshifts (Z >1–3) and dominate the extragalactic submillimetre sky, first detected by SCUBA. • JCMT is equipped with SCUBA-2, a continuation from SCUBA (Submillimetre Common-User Bolometer Array: which is second only to the Hubble Space Telescope in terms of publication of high-impact astronomical research) • Its goal of detecting the thousands of high-redshift starbursts and active galactic nuclei needed to understand the significance of the dust-obscured phase in the growth of galaxies and super-massive black holes.

  22. ZARAH DAN DAYA 2017, UNIVERSITI MALAYA, 26TH DECEMBER 2017 SCIENCE WITH EAST ASIA OBSERVATORY • The North Ecliptic Pole (NEP) is one of the most frequently visited areas on the sky because of easy accessibility to the space missions. We now have extensive data sets covering almost all wavelengths from UV to radio for a region centered at the NEP. • With SCUBA-2, JCMT aims to make Spectral Energy Distribution (SED) surveys with focus on infrared fitting, and covering spectroscopic optical and radio observations. • The plan is to observe the entire large of around 4 square degrees centered on NEP with SCUBA-2 850μm to fill the gap between the Herschel 500μm and ground-based radio data at 21cm. • By adding the new data from the survey, it is hoped that the following outstanding questions regarding the evolution of the galaxies may be answered: What is the origin of the Cosmic Infrared Background? Is it due to the very first population of stars, the intracluster halo stars or something else?

  23. ZARAH DAN DAYA 2017, UNIVERSITI MALAYA, 26TH DECEMBER 2017 SCIENCE WITH EAST ASIA OBSERVATORY • The JCMT plays a leading role in tracing the distribution and physical properties of the molecular gas and dust in nearby galaxies. • Multi-frequency spectral line data from the JCMT have been essential for investigating the density and temperature of the molecular gas and their variations with environment • The JCMT Nearby Galaxies Legacy Survey (NGLS) is the largest survey (155 galaxies) of molecular gas with sub-kiloparsec resolution. • The NGLS provides resolved measures of the gas-to-dust mass ratio and a recalibration of the CO-to-H2 conversion factor in galaxies. • These properties are essential to building a complete understanding of the links between star formation and the dense interstellar medium in present-day galaxies.

  24. ZARAH DAN DAYA 2017, UNIVERSITI MALAYA, 26TH DECEMBER 2017 SCIENCE WITH EAST ASIA OBSERVATORY • Other JCMT Nearby Galaxies Legacy Survey (NGLS) goals include: • Comparing galaxies with similar morphologies and luminosities in the field and in the Virgo cluster to determine the effects of cluster membership; • Using CO rotation curves to trace the dark matter distribution and the frequency of occurrence of nuclear gas concentrations which may feed central starbursts or black holes • Subaru: Large scale surveys at optical and near IR, compliments JCMT especially focusing on SMBH. • SMA: Radio galaxy surveys at 180-418 GHz
