    • Alma observations reveal no preferred outflow -filament and outflow- magnetic field orientations in protoclusters 
      Baug, T.; Wang, Ke; Liu, Tie; Tang, Mengyao; Zhang, Qizhou; Li, Di; Eswaraiah, Chakali; Liu, Sheng-Yuan; Tej, Anandmayee; Goldsmith, Paul; Bronfman Aguiló, Leonardo; Qin, Sheng-Li; Toth, Viktor; Li, Pak-Shing; Kim, Kee-Tae (IOP Publishing, 2020)
      We present a statistical study of the orientation of outflows with respect to large-scale filaments and magnetic fields. Although filaments are widely observed toward Galactic star-forming regions, the exact role of filaments ...
    • ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP): detection of extremely high-density compact ... 
      Sahu, Dipen; Liu, Sheng-Yuan; Liu, Tie; Evans II, Neal J.; Hirano, Naomi; Tatematsu, Ken'ichi; Lee, Chin-Fei; Kim, Kee-Tae; Dutta, Somnath; Alina, Dana; Bronfman, Leonardo; Cunningham, María; Eden, David J.; Garay Brignardello, Guido Alejandro; Goldsmith, Paul F.; He, Jinhua; Hsu, Shih-Ying; Goldsmith, Paul F.; He, Jinhua; Hsu, Shih-Ying; Jhan, Kai-Syun; Johnstone, Doug; Juvela, Mika; Kim, Gwanjeong; Kuan, Yi-Jehng; Kwon, Woojin; Lee, Chang Won; Lee, Jeong-Eun; Li, Di; Li, Pak Shing; Li, Shanghuo; Luo, Qiu-Yi; Montillaud, Julien; Moragha, Anthony; Pelkonen, Veli-Matti; Qin, Sheng-Li; Ristorcelli, Isabelle; Sanhueza, Patricio; Shang, Hsien; Shen, Zhi-Qiang; Soam, Archana; Wu, Yuefang; Zhang, Qizhou; Zhou, Jianjun (IOP, 2021)
      Prestellar cores are self-gravitating dense and cold structures within molecular clouds where future stars are born. They are expected, at the stage of transitioning to the protostellar phase, to harbor centrally concentrated ...
    • ALMA survey of Orion planck galactic cold clumps (ALMASOP): evidence for a molecular jet launched at an ... 
      Dutta, Somnath; Lee, Chin-Fei; Hirano, Naomi; Liu, Tie; Johnstone, Doug; Liu, Sheng-Yuan; Tatematsu, Ken'ichi; Goldsmith, Paul F.; Sahu, Dipen; Evans, Neal J.; Sanhueza, Patricio; Kwon, Woojin; Qin, Sheng-Li; Samal, Manash Ranjan; Zhang, Qizhou; Kim, Kee-Tae; Shang, Hsien; Lee, Chang Won; Moraghan, Anthony; Jhan, Kai-Syun; Li, Shanghuo; Lee, Jeong-Eun; Traficante, Alessio; Juvela, Mika; Bronfman Aguiló, Leonardo Jaime; Eden, David; Soam, Archana; He, Jinhua; Liu, Hong-li; Kuan, Yi-Jehng; Pelkonen, Veli-Matti; Luo, Qiuyi; Yi, Hee-Weon; Hsu, Shih-Ying (IOP, 2022)
      Protostellar outflows and jets play a vital role in star formation as they carry away excess angular momentum from the inner disk surface, allowing the material to be transferred toward the central protostar. Theoretically, ...
    • An ALMA study of outflow parameters of protoclusters: outflow feedback to maintain the turbulence 
      Baug, T.; Wang, Ke; Liu, Tie; Wu, Yue-Fang; Li, Di; Zhang, Qizhou; Tang, Mengyao; Goldsmith, Paul F.; Liu, Hong-Li; Tej, Anandmayee; Bronfman Aguiló, Leonardo Jaime; Kim, Kee-Tae; Li, Shanghuo; Lee, Chang Won; Tatematsu, Ken'ichi; Hirota, Tomoya; Toth, L. Viktor (Oxford, 2021)
      With the aim of understanding the role of outflows in star formation, we performed a statistical study of the physical parameters of outflows in 11 massive protoclusters associated with ultracompact H II regions. A total ...
    • Convergent filaments contracting towards an intermediate-mass pre-stellar core 
      Ren, Zhiyuan; Zhu, Lei; Shi, Hui; Yue, Nannan; Li, Di; Zhang, Qizhou; Mardones Pérez, Diego; Wu, Jingwen; Jiao, Sihan; Liu, Shu; Luo, Gan; Xie, Jinjin; Zhang, Chao; Xu, Xuefang (Oxford, 2021)
      Filamentary structures are closely associated with star-forming cores, but their detailed physical connections are still not clear. We studied the dense gas in OMC-3 MMS-7 region in the Orion A molecular cloud using the ...
    • Follow-up Observations Toward Planck Cold Clumps with Ground-Based Radio Telescopes 
      Liu, Tie; Wu, Yuefang; Mardones Pérez, Diego; Kim, Kee-Tae; Menten, Karl; Tatematsu, Ken; Cunningham, Maria; Juvela, Mika; Zhang, Qizhou; Goldsmith, Paul; Liu, Sheng-Yuan; Zhang, Hua-Wei; Meng, Fanyi; Li, Di; Lo, Nadia; Guan, Xin; Yuan, Jinghua; Belloche, Arnaud; Henkel, Christian; Wyrowski, Friedrich; Garay Brignardello, Guido; Ristorcelli, Isabelle; Lee, Jeong-Eun; Wang, Ke; Bronfman Aguiló, Leonardo; Toth, L.; Schnee, Scott; Qin, Shengli; Akhter, Shaila (The Korean Astronomical Society, 2015-09)
      The physical and chemical properties of prestellar cores, especially massive ones, are still far from being well understood due to the lack of a large sample. The low dust temperature (< 14 K) of Planck cold clumps makes ...

      Liu, Tie; Zhang, Qizhou; Kim, Kee-Tae; Wu, Yuefang; Lee, Chang Won; Lee, Jeong-Eun; Tatematsu, Kenichi; Choi, Minho; Juvela, Mika; Thompson, Mark; Goldsmith, Paul F.; Liu, Sheng-yuan; Naomi, Hirano; Koch, Patrick; Henkel, Christian; Sanhueza, Patricio; He, JinHua; Rivera-Ingraham, Alana; Wang, Ke; Cunningham, María R.; Tang, Ya-Wen; Lai, Shih-Ping; Yuan, Jinghua; Li, Di; Fuller, Gary; Kang, Miju; Luong, Quang Nguyen; Liu, Hauyu Baobab; Ristorcelli, Isabelle; Yang, Ji; Xu, Ye; Hirota, Tomoya; Mardones Pérez, Diego; Qin, Sheng-Li; Chen, Huei-Ru; Kwon, Woojin; Meng, Fanyi; Zhang, Huawei; Kim, Mi-Ryang; Yi, Hee-Weon (IOP Publisihing, 2016)
      We are performing a series of observations with ground-based telescopes toward Planck Galactic cold clumps (PGCCs) in the lambda Orionis complex in order to systematically investigate the effects of stellar feedback. In ...
