IAU Symposium 377 @ Kuala Lumpur, Malaysia. The first IAU conference in Southeast Asia since 1990. The conference will be held in a hybrid mode.
A comparative study of surviving dwarf galaxies versus what we have uncovered of cannibalized dwarf galaxies.
succeed (or not) at predicting the observed properties of galaxies
as inferred from both local group and high-redshift observations.
Malaysia has never previously hosted an IAU (International Astronomical Union) conference, neither have Malaysia’s neighboring countries: Cambodia, Singapore, Thailand, and Vietnam. Indonesia last held one in 1990, about 30 years ago. Together, these Southeast Asian countries are home to about 500 million people, a larger population than the EU. This conference aims to provide an opportunity to grow the international astronomical community.
The fields of Galactic archaeology and near-field cosmology have been revolutionized by a plethora of rich data from virtually every observational domain. This breadth from the most ancient field of astronomy (astrometry) to one of the newest (asteroseismology). We now know the precise kinematics, detailed chemical abundances, and approximate ages for millions of stars across much of the Milky Way, from the Bulge to the Solar Neighbourhood through to the Halo. This incredible bounty of astronomical data is accompanied by increasingly sophisticated astrophysical models in hierarchical galaxy assembly, galactic dynamics, stellar evolution, and nucleosynthetic yields.
These resources have led to an emerging picture of the Milky Way's first three billion years. The first phase of star-formation was likely dominated by metal-poor ([Fe/H] <= -3.0) gas and stars, whose chemical abundances represent a zoo in their suggested diversity of early chemical polluters. Some brief time later, the Milky Way formed its first globular clusters, its Bulge, and its Thick Disk, with the earliest phases of that epoch likely having been dominated by globular clusters. Simultaneous to these developments, the early Milky Way experienced several significant accretion events, such as the recently discovered systems Gaia-Enceladus and Sequoia. We can trace these structures dynamically, and chemically, and we may even be able to identify which globular clusters belonged to them. These accretion and dissolution events stand in contrast to the Milky Way’s puzzlingly quiescent state today.
In parallel to these developments in Galactic astronomy, the field of galaxy formation is also undergoing a revolution due to high-redshift data from Atacama Large Millimeter/submillimeter Array (ALMA). This progress will soon be accelerated by data from the Christmas 2021 launch of the James Webb Space Telescope (JWST). The question of how galaxies form and evolve will be constrained by a deluge of information from the earliest epochs, which will be both challenging and fascinating to analyze, interpret, and understand. We will ascertain the spread in abundances of gas at the same early cosmological epoch, the structural state of galaxies when the progenitors of globular clusters are driving the first significant star formation events, and the mass distribution of star formation events at high redshift. JWST will also probe the stellar mass functions of low-metallicity stellar populations, enabling new insights into the physical processes that drive the formation of stars and the resulting chemical enrichment of the universe.
Magnificent data (from both the Local Group and the high-redshift Universe) and state-of-the-art models are optimally insightful when used together. Given recent developments, the time is now to bring in experts from these three areas (Galactic astronomy, high-redshift astronomy, and theory and modeling of galaxy formation and evolution). The conference will enable a more holistic understanding of the Milky Way's and all disk galaxies’ early star formation and structural assembly.

The Global Malaysian Astronomy Convention, a conference celebrating works from Malaysian astronomers worldwide, will be held around the same time. Join us there too.
Everything you need to know about Malaysia.
Malaysia is a tropical country, in fact Kuala Lumpur is located a mere 4 degrees north from the equator. The typical temperature is 30 Celcius (85 F) in the daytime and 25 Celcius (75 F) at night. But Malaysians hate heat as much as you, so the country is filled, literally, with air conditioners. So you should wear casual when you go outside, but just wear as you usually would indoors. In fact, most Malaysian shopping malls are notoriously cold with the AC, so bring your autumn jacket.
We are proud to be a multi-ethnic country. The multi-ethnicity is largely because Malaysia (in particular, the Strait of Malacca) was the central hub of commerce in the 1400-1500s. Many Chinese and Indians came here to do business and subsequently stayed here since. During the colonial time (Malaysia was basically colonized by everyone - Portugese, Spanish, Dutch, British), many Chineses and Indians were also brought here by the colonizers (especially British) to build the railroads. The current racial composition is about 65% Malay, 25% Chinese, 7% Indian, and a small population of indigenous people (about 0.7% in the peninsula and 11% in the Borneo island).
The organizers are still frantically gathering information on this question.
Durian is commonly known as the "king of all fruits," but is also highly polarized. Some people find it extraordinarily fragrant, and some find it pungent beyond belief. In fact, Singapore bans durian across all public transport because it is too smelly. Durian was produced mostly in Malaysia and Thailand, but it has gained popularity in large parts of Asia in recent years. Some countries are so into durian that durian is made into almost everything imaginable -- durian pizza, durian milkshake, durian mooncake, durian puff. You name it. And yes, you can use durian as a physical defense weapon (Google it).
Since Malaysian is a multi-ethnic country, most Malaysians speak about 2-5 languages (including dialects). Nearly all Malaysians speak decent English and Malay (part of the Austronesian [Malayo-Polynesian] language family). On top of that, most Malaysian Chinese also speak proper Mandarin and at least a few dialects (mainly Cantonese, Hokkien, Hakka in Kuala Lumpur). Many Malaysian Indians also speak fluent Tamils and sometimes Hindu. It should be noted that, while most Malaysians can speak proper English (after all, we were part of the British colony until 1957 -- and yes, you might find older generation to speak fluent English because of that), it is not uncommon for Malaysians to mix three or more languages (in a single sentence!) in verbal communication. And that can be confusing if you are not used to it.
Food. Here is a non-exhaustive list: Nasi Lemak (Malay), Laksa (Malay), Rendang (Malay), Satay (Malay), Roti Canai (Indian), Roti Tissue (Indian), Nasi Briyani (Indian), Chow Kuay Teow (Chinese), Hokkien Mee (Chinese), Popiah (Chinese), Pan Mee (Chinese). You can thank us later.
The living expense in Kuala Lumpur (even being one of the most expensive cities in Malaysia) is still highly affordable. You can get a decent restaurant meal at about 5 USD, and probably even cheaper in a night market. A metro ticket is about 1 USD, and a short taxi ride is about 5 USD.
Since Malaysia is a multi-cultural country with a vast population of international travelers, most foreigners do not find any problem traveling in Malaysia. We do note that different people in Malaysia might have different restrictions. For example, Muslims cannot drink alcohol. That said, alcohol is accessible for other populations in Malaysia (and hence foreigners). There is also a decent population of vegetarians in Malaysia (e.g., Buddhism). The important thing is to be mindful -- for instance, you might want to consider other places than an alcohol bar when bringing your ethnic Malay friends for a science chat. But need not worry, Malaysians are very easy to get along with because of our upbringing -- we are very used to discussing our differences openly and restrictions (if any).
