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…
Measuring the 8621 Å Diffuse Interstellar Band in Gaia DR3 RVS Spectra: Obtaining a Clean Catalog by Marginalizing over Stellar Types
Andrew K. Saydjari, Ana Sofía M. Uzsoy, Catherine Zucker +2
Diffuse interstellar bands (DIBs) are broad absorption features associated with interstellar dust and can serve as chemical and kinematic tracers. Conventional measurements of DIBs…
The Solar Neighborhood in the Age of Gaia
Catherine Zucker, João Alves, Alyssa Goodman +2
Most of what we know about the formation of stars, and essentially everything we know about the formation of planets, comes from observations of our solar neighborhood within 2 kpc…
Characterizing the 3D Kinematics of Young Stars in the Radcliffe Wave
Alan J. Tu, Catherine Zucker, Joshua S. Speagle +5
We present an analysis of the kinematics of the Radcliffe Wave, a 2.7-kpc-long sinusoidal band of molecular clouds in the solar neighborhood recently detected via 3D dust mapping.…
The Dark Energy Camera Plane Survey 2 (DECaPS2): More Sky, Less Bias, and Better Uncertainties
A. K. Saydjari, E. F. Schlafly, D. Lang +10
Deep optical and near-infrared imaging of the entire Galactic plane is essential for understanding our Galaxy's stars, gas, and dust. The second data release of the DECam Plane Sur…
Spectroscopic Confirmation of a Population of Isolated, Intermediate-Mass YSOs
Michael A. Kuhn, Ramzi Saber, Matthew S. Povich +8
Wide-field searches for young stellar objects (YSOs) can place useful constraints on the prevalence of clustered versus distributed star formation. The Spitzer/IRAC Candidate YSO (…
Disconnecting the Dots: Re-Examining the Nature of Stellar "Strings" in the Milky Way
Catherine Zucker, J. E. G. Peek, Sarah R. Loebman
Recent analyses of Gaia data have resulted in the identification of new stellar structures, including a new class of extended stellar filaments called stellar "strings", first prop…
The Radcliffe Wave as the gas spine of the Orion Arm
Cameren Swiggum, João Alves, Elena D'Onghia +7
The Radcliffe Wave is a kpc long coherent gas structure containing most of the star-forming complexes near the Sun. In this Letter we aim to find a Galactic context for the…
The Magnetic Field in the Milky Way Filamentary Bone G47
Ian W. Stephens, Philip C. Myers, Catherine Zucker +21
Star formation primarily occurs in filaments where magnetic fields are expected to be dynamically important. The largest and densest filaments trace spiral structure within galaxie…
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,…
