Survey of Profile Parameters of the Diffuse Interstellar Band. From Uniform Profiles to Doppler Splitting and Blueshifts
M. Piecka, S. Hutschenreuter, J. Alves
The diffuse interstellar band (DIB) at 6196 A exhibits notable profile variations across the Milky Way. This study addresses three open issues: the unusual broadening of the DIB pr…
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 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…
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…
