Accelerated gas flow along Ophiuchus B44 filament: Breaking Position-Position-Velocity degeneracy
J. Alves, C. Zucker, C. Lada +15
(Abridged) Stellar feedback from massive stars in the Upper-Sco has been proposed to have reshaped the gas in the nearby Ophiuchus complex. In this framework, feedback organizes th…
Analytic Modeling of CO Surface-Density Profiles in the M31 Molecular Clouds
Eric Keto, Charles Lada, Jan Forbrich
We analyze CO observations of molecular clouds in the Andromeda galaxy (M31) with a new method to derive surface-density profiles and compare directly with projected solutions of t…
Origin of the IRAS Vela Shell: New Insights from 3D Dust Mapping
Bore Annie Gao, Catherine Zucker, Tirupati Kumara Sridharan +15
The IRAS Vela Shell (IVS) is a structure of enhanced FIR emission located towards the Gum Nebula, a prominent region of emission in the local Milky Way shaped by various…
HP2 Survey V. Ophiuchus: Filament formation in a dispersing cloud complex
João Alves, Marco Lombardi, Charles Lada
We search for potential ``birthmarks'' left from the formation of filamentary molecular clouds in the Ophiuchus complex. We use high dynamic-range column density and temperature ma…
