Resolving the heart of the Wolf-Rayet binary Apep with ALMA
S. del Palacio, W. Vlemmings, M. Fernández-López +5
The Wolf-Rayet (WR) phase is a critical stage in the evolution of massive stars. During this phase, the stars experience a large mass loss in the form of fast winds that are enrich…
The dominance of turbulence over magnetism in the formation of massive star cluster seeds
Junhao Liu, Patricio Sanhueza, Piyali Saha +32
High-mass stars form in protoclusters, where gravo-magnetic processes shape collapsing clouds and clumps to be elongated preferentially perpendicular to magnetic (B) fields. Yet it…
Multi-band ALMA Polarization Observations of BHB07-11 Reveal Aligned Dust Grains in Complex Spiral Arm Structures
Austen Fourkas, Leslie W. Looney, Zhe-Yu Daniel Lin +8
Polarization-mode observations from the Atacama Large Millimeter/submillimeter Array (ALMA) are powerful tools for studying the dust grain populations in circumstellar disks. Many…
First results from ALPPS: a sub-Alfvénic streamer in SVS13A
P. C. Cortes, J. E. Pineda, T. -H. Hsieh +22
We present the first results from the ALMA Perseus Polarization Survey (ALPPS), focusing on the magnetic field in the SVS13A circumbinary disk. The dataset includes full-Stokes dus…
Magnetic Fields in the Pillars of Creation
Adwitiya Sarkar, Leslie W. Looney, Marc W. Pound +7
Due to dust grain alignment with magnetic fields, dust polarization observations of far-infrared emission from cold molecular clouds are often used to trace magnetic fields, allowi…
L1448 IRS3B: Dust Polarization Aligned with Spiral Features, Tracing Gas Flows
Leslie W. Looney, Zhe-Yu Daniel Lin, Zhi-Yun Li +11
Circumstellar disk dust polarization in the (sub)millimeter is, for the most part, not from dust grain alignment with magnetic fields but rather indicative of a combination of dust…
Magnetic Fields in Massive Star-forming Regions (MagMaR). V. The Magnetic Field at the Onset of High-mass Star Formation
Patricio Sanhueza, Junhao Liu, Kaho Morii +36
A complete understanding of the initial conditions of high-mass star formation and what processes determine multiplicity require the study of the magnetic field (B-field) in young,…
ALMA-IMF XV: The core mass function in the high-mass star-formation regime
F. Louvet, P. Sanhueza, A. Stutz +38
The stellar initial mass function (IMF) is critical to our understanding of star formation and the effects of young stars on their environment. On large scales, it enables us to us…
Magnetic Fields in Massive Star-forming Regions (MagMaR): Unveiling an Hourglass Magnetic Field in G333.46-0.16 using ALMA
Piyali Saha, Patricio Sanhueza, Marco Padovani +33
The contribution of the magnetic field to the formation of high-mass stars is poorly understood. We report the high-angular resolution (, 870 au) map of the…
ALMA-IMF XII: Point-process mapping of 15 massive protoclusters
P. Dell'Ova, F. Motte, A. Gusdorf +29
A crucial aspect in addressing the challenge of measuring the core mass function, that is pivotal for comprehending the origin of the initial mass function, lies in constraining th…
MagMar III -- Resisting the Pressure, Is the Magnetic Field Overwhelmed in NGC6334I?
Paulo C. Cortes, Josep M. Girart, Patricio Sanhueza +23
We report on ALMA observations of polarized dust emission at 1.2 mm from NGC6334I, a source known for its significant flux outbursts. Between five months, our data show no substant…
Protoplanetary Disk Polarization at Multiple Wavelengths: Are Dust Populations Diverse?
Rachel E. Harrison, Zhe-Yu Daniel Lin, Leslie W. Looney +4
Millimeter and sub-millimeter observations of continuum linear dust polarization provide insight into dust grain growth in protoplanetary disks, which are the progenitors of planet…
ALMA-IMF XIII: NH kinematic analysis on the intermediate protocluster G353.41
R. H. Álvarez-Gutiérrez, A. M. Stutz, N. Sandoval-Garrido +23
The ALMA-IMF Large Program provides multi-tracer observations of 15 Galactic massive protoclusters at matched sensitivity and spatial resolution. We focus on the dense gas kinemati…
Aligned Grains and Scattered Light Found in Gaps of Planet-Forming Disk
Ian W. Stephens, Zhe-Yu Daniel Lin, Manuel Fernandez-Lopez +8
Polarized (sub)millimeter emission from dust grains in circumstellar disks was initially thought to be due to grains aligned with the magnetic field. However, higher resolution mul…

Daniel J. Díaz-González, Roberto Galván-Madrid, Adam Ginsburg +17
We present the combination of ALMA-IMF and single-dish continuum images from the Mustang-2 Galactic Plane Survey (MGPS90) at 3 millimeters and the Bolocam Galactic Plane Survey (BG…
Eccentric Dust Ring in the IRS 48 Transition Disk
Haifeng Yang, Manuel Fernandez-Lopez, Zhi-Yun Li +4
Crescent-shaped structures in transition disks hold the key to studying the putative companions to the central stars. The dust dynamics, especially that of different grain sizes, i…
