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 evolution of velocity dispersion in the Sco-Cen OB association

Josefa E. Großschedl, João Alves, Sebastian Ratzenböck +4

We study how the stellar velocity dispersion within the Scorpius-Centaurus OB association (Sco-Cen) has evolved over approximately 20 million years, from its formation to the prese…

Precise determination of circumstellar disk lifetimes: Disk evolution in a single star-forming region

Fabian A. Polnitzky, Sebastian Ratzenböck, Josefa E. Großschedl +1

Determining how long circumstellar disks last is key to understanding the timescale of planet formation. Typically, this is done by measuring the fraction of young stars with infra…

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…

The late Miocene Be anomaly and the possibility of a supernova

E. Maconi, J. Alves, J. Großschedl +3

Recent measurements of cosmogenic Be in deep-ocean ferromanganese crusts from the Central and Northern Pacific have revealed an anomalous concentration between 11.5 and 9.0…

The Solar System's passage through the Radcliffe wave during the middle Miocene

E. Maconi, J. Alves, C. Swiggum +14

Context. As the Solar System orbits the Milky Way, it encounters various Galactic environments, including dense regions of the interstellar medium (ISM). These encounters can compr…
