The SEDIGISM survey: first data release and overview of the Galactic structure
F. Schuller, J. S. Urquhart, T. Csengeri +57
The SEDIGISM (Structure, Excitation and Dynamics of the Inner Galactic Interstellar Medium) survey used the APEX telescope to map 84 deg^2 of the Galactic plane between l = -60 deg…
The SEDIGISM survey: Molecular clouds in the inner Galaxy
A. Duarte-Cabral, D. Colombo, J. S. Urquhart +57
We use the 13CO(2-1) emission from the SEDIGISM high-resolution spectral-line survey of the inner Galaxy, to extract the molecular cloud population with a large dynamic range in sp…
SEDIGISM-ATLASGAL: Dense Gas Fraction and Star Formation Efficiency Across the Galactic Disk
J. S. Urquhart, C. Figura, J. R. Cross +32
By combining two surveys covering a large fraction of the molecular material in the Galactic disk we investigate the role the spiral arms play in the star formation process. We hav…
How do different spiral arm models impact the ISM and GMC population?
Alex R. Pettitt, Clare L. Dobbs, Junichi Baba +4
The nature of galactic spiral arms in disc galaxies remains elusive. Regardless of the spiral model, arms are expected to play a role in sculpting the star-forming interstellar med…
The power of co-ordinate transformations in dynamical interpretations of Galactic structure
Jason A. S. Hunt, Kathryn V. Johnston, Alex R. Pettitt +3
DR2 has provided an unprecedented wealth of information about the positions and motions of stars in our Galaxy, and has highlighted the degree of disequilibria in the disc.…
Birth Sites of Young Stellar Associations and Recent Star Formation in a Flocculent Corrugated Disk
Alice C. Quillen, Alex R. Pettitt, Sukanya Chakrabarti +3
With backwards orbit integration we estimate birth locations of young stellar associations and moving groups identified in the solar neighborhood that are younger than 70 Myr. The…
Massive core/star formation triggered by cloud-cloud collision: Effect of magnetic field
Nirmit Sakre, Asao Habe, Alex R. Pettitt +1
We study effect of magnetic field on massive dense core formation in colliding unequal molecular clouds by performing magnetohydrodynamic simulations with sub-parsec resolution (0.…
