Interstellar dust in 3D at parsec-scale resolution out to 1.25 kiloparsecs in distance
Gordian Edenhofer MPA, Munich, DE | |
| Interstellar dust traces the mass in the ISM and is a crucial catalyst for star formation. To study the structure of the ISM and the conditions for star formation, we need to study the distribution of dust in 3D. However, we only observe interstellar dust in 2D projections. In this talk I will discuss how we can use astrometic data namely distance and extinction information from Gaia to de-project our 2D view of the sky to 3D. I will present a 3D map of interstellar dust extending out to 1.25 kiloparsecs in distance from the Sun. The 3D map improves upon previous high resolution 3D maps in terms of covered volume and resolution. It reveals previously undiscovered faint molecular clouds at high latitudes and far away distances, and significantly improves the dynamic range with which we resolve nearby molecular clouds. | |
