TL;DR: In this article, the authors make use of existing multi-wavelength data including recently available far-IR continuum and mm spectral line (H2O Southern Galactic Plane Survey and Millimetre Astronomy Legacy Team 90 GHz Survey) data and present new, deep, multiple-filter, near-IR (Very Large Telescope/NACO) observations to study G0.253 + 0.016.

TL;DR: In this paper, the authors present the UH Research Archive for Astronomy & Astrophysics (UHRA) for personal research, educational, and non-commercial purposes only.

TL;DR: In this paper, the Gaia DR2 distances of about 700 selected young stellar objects in the benchmark giant molecular cloud Orion A were used to infer its 3D shape and orientation, and they found that Orion A is not the fairly straight filamentary cloud that we see in (2D) projection, but instead a cometary-like cloud oriented toward the Galactic plane, with two distinct components: a denser and enhanced star-forming (bent) Head, and a lower density and star-formation quieter ∼75 pc long Tail.

TL;DR: In this article, the authors used the mid-infrared DR2 distances of about 700 young stellar objects in the benchmark giant molecular cloud Orion A to infer its 3D shape and orientation, and found that Orion A is not the fairly straight filamentary cloud that we see in (2D) projection, but instead a cometary-like cloud oriented toward the Galactic plane, with two distinct components: a denser and enhanced star-forming (bent) Head, and a lower density and star-formation quieter $75 pc long Tail.

TL;DR: In this article, the authors make use of existing multi-wavelength data including recently available far-IR continuum (Herschel/Hi-GAL) and mm spectral line (HOPS and MALT90) data and present new, deep, multiple-filter, near-IR (VLT/NACO) observations to study G0.253+0.016.
