HASHTAG is large project on the James Clerk Maxwell Telescope to make the first ground-based sub-mm map of Andromeda as well as CO(J=3-2) of selected regions. These maps will be used to perform the most detailed analysis of cosmic dust and its relation to the ISM and star-formation across the entire galaxy.
The James Clark Maxwell Telescope (JCMT) is the world's largest single-dish sub-mm telescope. Its 15m dish is situated on the top of MauneaKea in Hawaii, one of the best observing sites in the world. Find out more on the JCMT website.
HASHTAG was allocated a total of 275 hours on the JCMT. We used 55 hours to observe the CO(J=3-2) line using the HARP instrument. The 220 hours from HASHTAG were combined with our former pilot project (35 hours) to map the entirity of Andromeda with SCUBA-2.
Andromeda (M31) is our neighest neighbour, and in many ways is similar to our own galaxy the Milky Way. Our view of the Milky Way can be problematic as our solar system is located inside the Galaxy's disk, however, in Andromeda we can view the entire galaxy.
HASHTAG includes over 80 reserachers from colloborators in Canada, China, Japan, South Korea, Taiwan, United Kingdom, and at the East Asian Observatory.
Our first paper on our SCUBA-2 dust continuum data has been accepted to ApJS. This paper outlines the pipelines we developed to make our maps of Andromeda from the ground.
Our first HASHTAG paper presents our HARP CO maps and investigates how the properties of the molecular gas varies across Andromeda.
