Magnetic Fields in Massive Star-forming Regions (MagMaR). IX. Radiative Torque Alignment and Disruption in NGC6334I

Vineet Rawat, Thiem Hoang, Patricio Sanhueza +18

Intense radiation from high-mass stars is expected to significantly affect dust grain alignment and evolution through RAdiative Torques (RATs). We investigate this effect in a mass…

HOTDISK. Finding Massive Protostellar Disks with Water and Refractory Molecular Species

Kai Yang, Yichen Zhang, Kei E. I. Tanaka +16

We present high-angular-resolution (, au) ALMA Band~6 observations from the HOTDISK project (Hot-Origin Tracer survey of DISKs of massive pro…

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…

Digging into the Interior of Hot Cores with ALMA (DIHCA). VI. The Formation of Low-mass Multiple Systems in High-mass Cluster-forming Regions

Qiuyi Luo, Patricio Sanhueza, Stella S. R. Offner +14

Most stars form in multiple systems, with profound implications in numerous astronomical phenomena intrinsically linked to multiplicity. However, our knowledge about the process on…

Digging into the Interior of Hot Cores with ALMA (DIHCA). VII. Disk candidates around high-mass stars and evidence of anisotropic infall

Fernando A. Olguin, Patricio Sanhueza, Yoko Oya +19

We study the kinematics of condensations in 30 fields forming high-mass stars with ALMA at a high-resolution of ~0.08'' on average (~230 au). The presence of disks is important for…

MAGellanic Outflow and chemistry Survey (MAGOS): Hot cores in the LMC

Takashi Shimonishi, Kei E. I. Tanaka, Yichen Zhang +3

The Large Magellanic Cloud (LMC) provides a key laboratory for exploring the diversity of star formation and interstellar chemistry under subsolar metallicity conditions. We presen…

Deep Andromeda JCMT-SCUBA2 Observations. The Submillimeter Maps and Giant Molecular Clouds

Sihan Jiao, Jingwen Wu, Hauyu Baobab Liu +23

We have carried out unprecedentedly deep, nearly confusion-limited JCMT-SCUBA2 mapping observations on the nearest spiral galaxy, M31 (Andromeda). The 850 m image with a 5…

Magnetic Fields in Massive Star-forming Regions (MagMaR). VI. Magnetic Field Dragging in the Filamentary High-mass Star-forming Region G35.20--0.74N due to Gravity

Jihye Hwang, Patricio Sanhueza, Josep Miquel Girart +27

We investigate the magnetic field orientation and strength in the massive star-forming region G35.20-0.74N (G35), using polarized dust emission data obtained with the Atacama Large…

Massive extended streamers feed high-mass young stars

Fernando A. Olguin, Patricio Sanhueza, Adam Ginsburg +13

Stars are born in a variety of environments that determine how they gather gas to achieve their final masses. It is generally believed that disks are ubiquitous around protostars a…

Subclustering and Star Formation Efficiency in Three Protoclusters in the Central Molecular Zone

Suinan Zhang, Xing Lu, Adam Ginsburg +21

We present so far the highest resolution (0.04") ALMA 1.3 mm continuum observations of three massive star-forming clumps in the Central Molecular Zone, namely 20 km s…

ALMA observations of massive clouds in the central molecular zone: slim filaments tracing parsec-scale shocks

Kai Yang, Xing Lu, Yichen Zhang +22

The central molecular zone (CMZ) of our Galaxy exhibits widespread emission from SiO and various complex organic molecules (COMs), yet the exact origin of such emission is uncertai…

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,…

Magnetic Fields in Massive Star-forming Regions (MagMaR) IV: Tracing the Magnetic Fields in the O-type protostellar system IRAS 165474247

Luis A. Zapata, Manuel Fernández-López, Patricio Sanhueza +24

The formation of the massive stars, and in particular, the role that the magnetic fields play in their early evolutionary phase is still far from being completely understood. Here,…

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…
