The Magnetized Universe: From planet-forming disks to the high-redshift universe
Josep M Girart, Gary Fuller, Wouter Vlemmings +32
The interstellar medium (ISM) is magnetized at all scales and phases in our Galaxy and other galaxies across the Universe. Spectro-polarimetric millimetre observations are essentia…
Bridging the gap between stars and planets
Aina Palau, Dimitris Stamatellos, Matthew Bate +58
The formation mechanisms of brown dwarfs (BDs) and free-floating planets (FFPs) are poorly constrained. The two main competing scenarios include the star-like scenario, where these…
Star Formation across the Galaxy
Alvaro Sanchez-Monge, Henrik Beuther, Maryvonne Gerin +41
Star formation is both a multi-scale and highly dynamic process. It is regulated by the combination of gravity, turbulence, feedback and magnetic fields, which connect more than si…
Before fragmentation: from uniform clouds to stellar clusters
A. Giannetti, T. Pillai, J. Kauffmann +4
Our study of the early stages of fragmentation in massive clumps has revealed a striking anomaly: of the CoCoA sample exhibit no fragmentation at all. These sources coul…
Accurate proper motions of the protostellar system VLA1623-2417
Ricardo Hernández Garnica, Laurent Loinard, Carlos Carrasco-González +9
We present a detailed astrometric analysis of the quadruple protostellar system VLA1623-2417, deriving accurate absolute proper motions for components A, B, and W, as well as, for…
How Should We Understand the Core Mass Function? A memo of the CMF2IMF conference at ESO Garching
Fengwei Xu, Roberto Galvan-Madrid, Kaho Morii +4
The origin of the stellar initial mass function (IMF) remains one of the central questions in astronomy. Nearly three decades ago, the resemblance between the core mass function (C…
The efficiency per free-fall time as a ratio of the Star Formation Rate to the gas-infall rate in collapsing cores: dependence on the core definition, accretion, and radial structure
Fabián Quesada-Zúñiga, Manuel Zamora-Avilés, Enrique Vázquez-Semadeni +3
A parameter used to characterise star formation activity in MCs is the efficiency per free-fall time, , although commonly referred to as an efficiency, it is formally t…
Estimating the Luminosities of Protostars with Limited Infrared Photometry
Michael M. Dunham, Aina Palau, Nuria Huélamo +3
The luminosities of protostars provide one of the only indirect methods of measuring their masses and mass accretion rates in their earliest stages of evolution. Accurate measureme…
Comparing the Relation inside a Giant Molecular Cloud
Carlos G. Román-Zúñiga, Aina Palau, Javier Ballesteros-Paredes +3
In this paper we present a simple analysis around scaling relations derived from the Schmidt conjecture for star-forming molecular clouds, at the intra-cloud scale. Using a hierarc…
On the relation between magnetic field strength and gas density in the interstellar medium. II. Density uncertainties and diffuse gas constraints
David Whitworth, Amit Seta, Ralph E. Pudritz +4
The relationship between magnetic field strength and gas density is essential to understand the interstellar medium and star formation. Zeeman measurements in dense atomic and mole…
The ALMA-QUARKS survey: Investigating Thermal Feedback of Massive Protostars in Hot Molecular Cores
Dezhao Meng, Tie Liu, Jarken Esimbek +33
We identify a sample of 83 spatially resolved hot molecular cores (HMCs) in the QUARKS survey, aiming at investigating thermal feedback from massive stars. Using CHCN\,(12--11)…
Unveiling the First O-Type Bloated Star Candidate through ALMA and EVLA Observations

We present high-angular-resolution () VLA Ku-band (12--18 GHz) observations of two explosive molecular outflows (EMOs), DR 21 and G5.89, in a search for runaway s…
Synthetic polarization observations of magnetized pillars in HII regions: Assessing the reliability of the Davis-Chandrasekhar-Fermi method
Luis Andrés Hernández-Cruz, Manuel Zamora-Avilés, Abraham Luna +6
We investigated the morphology and strength of magnetic fields in pillar-shaped structures at the boundaries of HII regions by combining three-dimensional radiation-magnetohydrodyn…
The ALMA-QUARKS Survey: III. Clump-to-core fragmentation and search for high-mass starless cores
