A 3D View of Orion: I. Barnard's Loop
Michael M. Foley, Alyssa Goodman, Catherine Zucker +11
Barnard's Loop is a famous arc of H emission located in the Orion star-forming region. Here, we provide evidence of a possible formation mechanism for Barnard's Loop and compare…
Star formation near the Sun is driven by expansion of the Local Bubble
Catherine Zucker, Alyssa A. Goodman, João Alves +8
For decades we have known that the Sun lies within the Local Bubble, a cavity of low-density, high-temperature plasma surrounded by a shell of cold, neutral gas and dust. However,…
On the Three-Dimensional Structure of Local Molecular Clouds
Catherine Zucker, Alyssa Goodman, João Alves +9
We leverage the 1 pc spatial resolution of the Leike et al. 2020 3D dust map to characterize the three-dimensional structure of nearby molecular clouds ( pc). We st…
The Per-Tau Shell: A Giant Star-Forming Spherical Shell Revealed by 3D Dust Observations
Shmuel Bialy, Catherine Zucker, Alyssa Goodman +6
A major question in the field of star formation is how molecular clouds form out of the diffuse Interstellar Medium (ISM). Recent advances in 3D dust mapping are revolutionizing ou…
Evidence for Radial Expansion at the Core of the Orion Complex with Gaia EDR3
Cameren Swiggum, Elena D'Onghia, João Alves +6
We present a phase-space study of two stellar groups located at the core of the Orion complex: Briceño-1 and Orion Belt Population-near (OBP-near). We identify the groups with the…
