HURACAN: A comparison of stellar and interstellar proper motions inside L1688

M. Piecka, J. Alves, A. Rottensteiner +3

The assumption that molecular clouds are kinematically coupled to the young stellar populations forming within them is observationally still poorly constrained. With the transverse…

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…

Kinematics of young stellar objects in NGC 2024 based on infrared proper motions

Alena Rottensteiner, Monika G. Petr-Gotzens, Stefan Meingast +6

The most recently formed young stellar objects (YSOs) in active star forming regions are excellent tracers of their parent cloud motion. Their positions and dynamics provide insigh…

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 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…

Towards a complete picture of the Sco-Cen outflow

M. Piecka, S. Hutschenreuter, J. Alves

Previous studies have shown strong evidence that the Sun is crossing an outflow originating from the Sco-Cen OB association. Understanding this outflow's origin and structure illum…

VISIONS: The VISTA Star Formation Atlas -- I. Survey overview

Stefan Meingast, João Alves, Hervé Bouy +37

VISIONS is an ESO public survey of five nearby (d < 500 pc) star-forming molecular cloud complexes that are canonically associated with the constellations of Chamaeleon, Corona Aus…

The star formation history of the Sco-Cen association. Coherent star formation patterns in space and time

Sebastian Ratzenböck, Josefa E. Großschedl, João Alves +13

We reconstruct the star formation history of the Sco-Cen OB association using a novel high-resolution age map of the region. We develop an approach to produce robust ages for Sco-C…
