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…
The velocity field of the Scorpius-Centaurus OB association
S. Hutschenreuter, J. Alves, L. Posch +5
We present a non-parametric reconstruction of the three-dimensional velocity field of the Scorpius-Centaurus OB association (Sco- Cen). Using Gaia DR3 astrometry and radial velocit…
Direct measurement of ISM proper motion with image registration
M. Piecka, L. Posch, S. Meingast +3
To date, quantification of the on-sky motion for interstellar clouds have relied on proxies such as young stellar objects (YSO) and masers. We present the first direct measurement…
The TW Hydrae Association is a cluster chain of Sco-Cen
N. Miret-Roig, J. Alves, S. Ratzenböck +9
The TW Hydrae Association (TWA) is a young local association (YLA) about 50 pc from the Sun, offering a unique opportunity to study star and planet formation processes in detail. W…
