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…
The Nearby Star Formation and Supernova Histories Reconstructed from Young Star Clusters
Cameren Swiggum, Catherine Zucker, Michelangelo Pantaleoni González +8
We reconstruct the recent star formation and core-collapse supernova (ccSN) histories of the Solar Neighborhood from the past trajectories of young star clusters. Using a \textit{G…
A comprehensive cluster census of Orion. An application of the Significance Mode Analysis (SigMA) algorithm
Alena Rottensteiner, Sebastian Ratzenböck, João Alves +2
Precise astrometric surveys and modern clustering algorithms are working in step to transform our view of star-forming regions. By revealing a much richer substructure than previou…
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 Rapid ASKAP Continuum Survey VII: Spectra and Polarisation In Cutouts of Extragalactic Sources (SPICE-RACS) Second Data Release -- Unveiling the Magnetised Sky
Alec J. M. Thomson, Timothy J. Galvin, Stefan W. Duchesne +18
We present the second data release (DR2) of Spectra and Polarisation in Cutouts of Extragalactic sources from RACS (SPICE-RACS). SPICE-RACS DR2 is derived from the third low-band e…
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…
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…
