The SEDIGISM survey: Molecular cloud morphology. I. Classification and star formation
K. R. Neralwar, D. Colombo, A. Duarte-Cabral +22
We present one of the very first extensive classifications of a large sample of molecular clouds based on their morphology. This is achieved using a recently published catalogue of…
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…
Coherent control of magnetization precession by double-pulse activation of effective fields from magnetoacoustics and demagnetization
M. Mattern, F. -C. Weber, D. Engel +2
We demonstrate the coherent optical control of magnetization precession in a thin Ni film by a second excitation pulse which amplifies or attenuates the precession induced by a fir…
Probing the structure of a massive filament: ArTeMiS 350 and 450 micron mapping of the integral-shaped filament in Orion A
F. Schuller, Ph. André, Y. Shimajiri +18
(abridged) Within the Orion A molecular cloud, the integral-shaped filament (ISF) is a prominent, degree-long structure of dense gas and dust, with clear signs of recent and on-goi…
SEDIGISM: Structure, excitation, and dynamics of the inner Galactic interstellar medium
F. Schuller, T. Csengeri, J. S. Urquhart +41
The origin and life-cycle of molecular clouds are still poorly constrained, despite their importance for understanding the evolution of the interstellar medium. We have carried out…
The SEDIGISM survey: The influence of spiral arms on the molecular gas distribution of the inner Milky Way
D. Colombo, A. Duarte-Cabral, A. R. Pettitt +23
The morphology of the Milky Way is still a matter of debate. In order to shed light on uncertainties surrounding the structure of the Galaxy, in this paper, we study the imprint of…
A Kpc Scale Molecular Wave in the Inner Galaxy: Feather of the Milky Way?
V. S. Veena, P. Schilke, Ã. Sánchez-Monge +7
We report the discovery of a velocity coherent, kpc-scale molecular structure towards the Galactic center region with an angular extent of 30deg and an aspect ratio of 60:1. The ki…
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…
SEDIGISM: The kinematics of ATLASGAL filaments
M. Mattern, J. Kauffmann, T. Csengeri +13
Analysing the kinematics of filamentary molecular clouds is a crucial step towards understanding their role in the star formation process. Therefore, we study the kinematics of 283…
The SEDIGISM survey: Molecular cloud morphology. II. Integrated source properties
K. R. Neralwar, D. Colombo, A. Duarte-Cabral +21
The Structure, Excitation, and Dynamics of the Inner Galactic InterStellar Medium (SEDIGISM) survey has produced high (spatial and spectral) resolution CO (2-1) maps of the…
Emission of coherent THz magnons in an antiferromagnetic insulator triggered by ultrafast spin-phonon interactions
E. Rongione, O. Gueckstock, M. Mattern +17
Antiferromagnetic materials have been proposed as new types of narrowband THz spintronic devices owing to their ultrafast spin dynamics. Manipulating coherently their spin dynamics…
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…
OGHReS: Large-scale filaments in the outer Galaxy
D. Colombo, C. König, J. S. Urquhart +9
Filaments are a ubiquitous morphological feature of the molecular interstellar medium and are identified as sites of star formation. In recent years, more than 100 large-scale fila…
Understanding the Star Formation Efficiency in Dense Gas: Initial Results from the CAFFEINE Survey with ArTéMiS
M. Mattern, Ph. André, A. Zavagno +9
Despite recent progress, the question of what regulates the star formation efficiency in galaxies remains one of the most debated problems in astrophysics. According to the dominan…
