Welcome to the Personal Website of Tianyu Tu!

I am currently a fourth-year PhD student from the School of astronomy & Space Science of Nanjing University supervised by Prof. Yang Chen. In 2025, I visited the Laboratoire d’Astrophysique de Bordeaux under the co-supervision of Dr. Valentine Wakelam. My research interest is the physical and chemical changes in molecular clouds (MCs) associated supernova remnants (SNRs), including:

• Radio/mm/sub-mm observation of the physical properties of the MCs associated with SNRs, e.g. temperature and density.
• Radio/mm/sub-mm observation of the chemical effects of SNRs on MCs, including the chemistry brough by shock and cosmic rays (CRs), e.g. HCO+/CO, HOC+/HCO+, carbon chains, complex organic molecules, etc.
• Simulation of shock and CR chemistry, e.g. radiolysis of icy molecules by CRs.
• IR absorption of icy molecules in MCs associated with SNRs, e.g. the 3.0 micron H2O ice absorption.
• IR observation of H2 lines to probe SNR-MC interaction.

If you have any questions, or want to collaborate with me, please do not hesitate to email me (tianyu.tu1105 at outlook.com or tianyutu at smail.nju.edu.cn). The observational data of my publications will be available on Zenodo.
