A Monopolar Jet from Protostar HOPS 10: Evidence for Asymmetric Magnetized Launching

The Astronomical Journal
A fundamental challenge in star formation is understanding how a protostar accretes mass from its circumstellar disk while removing excess angular momentum.

Molecular Jets from an Evolved Protostar: Insights from JWST-ALMA Synergy

The Astrophysical Journal
The combination of the Atacama Large Millimeter/submillimeter Array (ALMA) and JWST/MIRI mid-infrared observations offers a transformative view of protostellar jets and outflows by probing cold and warm gas components across diverse physical conditions ...

Modeling Long-wavelength Amorphous Dust Emission Based on the Physically Motivated Soft-potential Model

The Astrophysical Journal
We propose a new amorphous dust emission model based on the soft-potential (SP) model, applicable in the long-wavelength range from the far-infrared to the microwave.

The ALMA-ATOMS Survey: Exploring Protostellar Outflows in HC3N

The Astrophysical Journal
We present the first systematic study of bipolar outflows using HC _3 N as a tracer in a sample of 146 massive star-forming regions from the Atacama Large Millimeter/submillimeter Array Three-millimeter Observations of Massive Star-forming Regions (ATOMS)

The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO). II. Dust and Gas Disk Properties in the Ophiuchus Star-forming Region

The Astrophysical Journal
The ALMA survey of Gas Evolution in PROtoplanetary disks (AGE-PRO) Large Program aims to trace the evolution of gas disk mass and size throughout the lifetime of protoplanetary disks by using the Atacama Large Millimeter/submillimeter Array (ALMA).

RUBIES: JWST/NIRSpec Resolves Evolutionary Phases of Dusty Star-forming Galaxies at z ∼ 2

The Astrophysical Journal
The dearth of high-quality spectroscopy of dusty star-forming galaxies (DSFGs)—the main drivers of the assembly of dust and stellar mass at the peak of activity in the Universe—greatly hinders our ability to interpret their physical processes and ...

High-dimensional Statistical Analysis and Its Application to an ALMA Map of NGC 253

The Astrophysical Journal Supplement Series
In astronomy, if we denote the dimension of data as d and the number of samples as n , we often find a case with n ≪ d . Traditionally, such a situation is regarded as ill-posed, and there was no choice but to discard most of the information in data ...
