Seminars

The UHH Research Park includes the headquarters for the East Asian Observatory, the Caltech Submillimeter Observatory, Subaru, Gemini, UKIRT, the Smithsonian Submillimeter Array and the Institute for Astronomy, plus the astronomers at the University of Hawaii at Hilo. We are one of the major centres for astronomy in the world and encourage all visitors to the JCMT to take advantage of the proximity of these institutes, and give a seminar while in Hilo. Your talk will be advertised at each of the above institutes.

Upcoming Seminar:

Title: Decoding the ISM in M31 Across Wavelengths: From Dust Properties to Anomalous Microwave Emission
Speaker: Sihan Jiao (National Astronomical Observatories, Chinese Academy of Sciences)
Abstract:
The interstellar medium (ISM) is a multi-phase ecosystem that can be probed through continuum emission across a wide range of wavelengths. In this talk, I present a multiwavelength investigation of the ISM in the Andromeda galaxy (M31). Using deep JCMT/SCUBA-2 observations, we construct a comprehensive catalog of 572 giant molecular clouds (GMCs), including 189 inter-arm GMCs, and examine their properties and star formation efficiency. By incorporating longer-wavelength data at 1.15 mm from IRAM 30 m/NIKA2, we further constrain the dust surface density, temperature, and emissivity index, revealing variations in these dust properties at GMC scales. Finally, we hunt for anomalous microwave emission (AME) in M31 using VLA observations, constructing a sample of 23 AME candidates and planning to investigate their possible emission mechanisms.

Where and How:

EAO seminars are (usually) held in the second floor conference room at the East Asia Observatory, 660 N. A’ohoku Place, Hilo, Hawaii. Please note that access to EAO is possible only through the main entrance (through the side doors facing Subaru). However since COVID we encourage astronomers to join via zoom.

We stream all of our seminars through the Zoom video conferencing application. If you would like to view the seminar via Zoom, links are sent out on the seminar mailing list (see below) or you may contact the helpdesk in advance of the talk and we will make sure that the option is available to you.

A full list of past seminar speakers can be found below for the current and previous years. These pages also contain links to PDF copies of the seminar slides, video recordings of the seminars, and other materials, when available.

To join the Seminar e-mail list:

EAO Seminars are sent out via eaoseminar@eaobservatory.org. If you wish to join this seminar list please send an e-mail to helpdesk@eaobservatory.org.
