The 1st Japan-Taiwan Joint Seminar on Single-Dish mm/Submm Telescope Studies
Dear all,
We, the organizers of the Japan-Taiwan Joint Seminar on Single-Dish mm/Submm Telescope Studies, are pleased to announce the first online seminar. This first joint seminar is part of the monthly Large Submillimeter Telescope (LST) Seminar series in Japan, which began in November 2021.
The seminar aims to foster discussion on various research directions for current and future single-dish telescopes and to strengthen collaboration among researchers in the field. As a reminder, the next seminar will be held this Thursday, July 10th. We are pleased to share the presentation title from our speaker, Yao-Lun Yang (RIKEN), and the Zoom access information below. Please feel free to forward this email to anyone who might be interested.

“PRIMA: Future of Far-Infrared Astronomy for Star Formation”
Understanding the origin of solar-type planetary systems remains one of the fundamental questions in astronomy. These systems form within dense, dusty clouds, where high extinction presents a significant challenge for direct observational studies of the physical and chemical processes at the onset of star and planet formation. Over the past decades, most studies have relied on submillimeter and millimeter interferometric observations — primarily using ALMA — to probe the cold dust and gas (~10–100 K), helping to constrain the structures and chemistry of planet-forming disks. More recently, the JWST has enabled unprecedented sensitivity at mid-infrared wavelengths, allowing us to characterize hot gas and dust (>1000 K). However, the bulk of the energy emitted by protostars and protoplanetary disks lies in the far-infrared regime (100–1000 K) — a spectral window that was once accessible through missions such as ISO, AKARI, SOFIA, and Herschel, but is no longer covered by current observatories. The PRobe far-Infrared Mission for Astrophysics (PRIMA) is a proposed mission designed to uniquely fill this observational gap.
PRIMA aims to probe the dominant components of gas and dust in star-forming regions, with a particular focus on protostellar and protoplanetary systems. In this talk, I will introduce the PRIMA mission concept and the efforts currently led by the Japanese astronomical community. I will also present several key science cases in star formation that PRIMA’s 24–235 μm imaging and spectroscopic capabilities can uniquely address. Additionally, I will highlight the synergy between PRIMA and the LST. Finally, I will share opportunities for researchers to get involved in the PRIMA project and contribute to its scientific goals.
