The ALMA-QUARKS Survey: Properties of Hot Molecular Fragments in the Massive Protocluster IRAS 17233-3606
Li Chen, Sheng-Li Qin, Dongting Yang +29
To investigate the physical mechanisms of fragmentation within the hot molecular core of the massive protocluster IRAS 17233-3606 (G351.78-0.54), we carried out a detailed analysis…
The Real and Pseudo Dispersion Measures of FRB~20220912A
Yi Feng, Dengke Zhou, Y. -K. Zhang +5
Fast radio bursts (FRBs) are millisecond-duration radio transients. As they propagate through the interstellar medium, they interact with free electrons, resulting in dispersion. T…
Evidence for the gravity-driven and magnetically-regularized gas flows feeding the massive protostellar cluster in Cepheus A
Panigrahy Sandhyarani, Chakali Eswaraiah, Di Li +8
The hierarchical interplay among gravity, magnetic fields, and turbulence in forming massive protostellar clusters remains elusive. We present high-resolution (14 arcsec $\si…
FAST Polarization Catalog of FRB 20240114A
Tian-Cong Wang, Jun-Shuo Zhang, Xiao-Hui Liu +60
Polarization measurements of fast radio bursts (FRBs) probe the magnetized plasma surrounding their central engines. FRB~20240114A is an exceptionally active repeating source, with…
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…
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 …
