VLBI astrometry of radio stars to link radio and optical celestial reference frames - II. 11 radio stars
Jingdong Zhang, Bo Zhang, Shuangjing Xu +10
The alignment between the radio-based International Celestial Reference Frame (ICRF) and the optical Gaia Celestial Reference Frame (Gaia-CRF) is critical for multi-waveband astron…
Tracking Protostellar Variability in Massive Protoclusters with ALMA: I. Insights from QUARKS and MaMMOtH
Yuhan Yang, Tie Liu, Sheng-Yuan Liu +22
Millimeter/submillimeter variability is often attributed to dynamical disk-mediated accretion, yet detection is limited to low-mass protostars in nearby clouds. Recent observations…
The ALMA-QUARKS survey: Evidence of a candidate high-mass prestellar core aside a bright-rimmed cloud IRAS 18290-0924
Dongting Yang, Hong-Li Liu, Shengli Qin +32
Although frequently reported in observations, the definitive confirmation of high-mass prestellar cores has remained elusive, presenting a persistent challenge in star formation st…
A misaligned protostellar disk fed by gas streamers in a barred spiral-like massive dense core
Xiaofeng Mai, Tie Liu, Xunchuan Liu +42
High-mass stars, born in massive dense cores (MDCs), profoundly impact the cosmic ecosystem through feedback processes and metal enrichment, yet little is known about how MDCs asse…
The ALMA-QUARKS Survey: III. Clump-to-core fragmentation and search for high-mass starless cores
Dongting Yang, Hong-Li Liu, Tie Liu +43
The Querying Underlying mechanisms of massive star formation with ALMA-Resolved gas Kinematics and Structures (QUARKS) survey observed 139 infrared-bright (IR-bright) massive proto…
Sulfur oxides tracing streamers and shocks at low mass protostellar disk-envelope interfaces
X. -C. Liu, E. F. van Dishoeck, M. R. Hogerheijde +8
Accretion shocks are thought to play a crucial role in the early stages of star and planet formation, but their direct observational evidence remains elusive, particularly regardin…
Validating the bright Gaia celestial reference frame with new VLBI astrometry of radio stars
Jingdong Zhang, Bo Zhang, Shuangjing Xu +1
There exist inconsistencies between the bright and faint Gaia Celestial Reference Frame 3 (Gaia-CRF3), which manifests as a systematic rotation and needs to be independently estima…
The ALMA-ATOMS survey: A sample of weak hot core candidates identified through line stacking
Zi-Yang Li, Xunchuan Liu, Tie Liu +33
Hot cores represent critical astrophysical environments for high-mass star formation, distinguished by their rich spectra of organic molecular emission lines. We aim to utilize hig…
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…
The orbital period of the long-period and colliding-wind binary WR 146 from radio interferometry of the shock cone
Shiming Wen, Bo Zhang, Shuangjing Xu +8
We report the first measurement of the orbital period of a long-period colliding-wind binary (CWB) system WR 146, derived by tracing the rotational morphology of its wind-colliding…
Network of velocity-coherent filaments formed by supersonic turbulence in a very-high-velocity HI cloud
Xunchuan Liu, Tie Liu, Pak-Shing Li +17
The warm neutral medium (WNM) was thought to be subsonically/transonically turbulent, and it lacks a network of intertwined filaments that are commonly seen in both molecular cloud…
Core mass function in view of fractal and turbulent filaments and fibers
Xunchuan Liu, Tie Liu, Xiaofeng Mai +5
We propose that the core mass function (CMF) can be driven by filament fragmentation. To model a star-forming system of filaments and fibers, we develop a fractal and turbulent tre…
Serial MultiView: an efficient approach to mitigating atmospheric spatial-structure errors for VLBI astrometry
Jingdong Zhang, Bo Zhang, Shuangjing Xu +4
Atmospheric propagation errors are a main constraint on the accuracy of Very Long Baseline Interferometry (VLBI) astrometry. For relative astrometry, differential techniques can mi…
