PhD of Science in Astrophysics​

​​I joined the VLBI group in the Max Planck Institute for Radio Astronomy for my doctoral research, under the supervision of Prof. Eduardo Ros and Prof. Anton Zensus. My research focused on understanding the dynamics and the physical properties of AGN jets. One of the main projects of my PhD was the study the inner jet of M87 using VLBA observations. I studied the dynamics and the evolution of the bright feature HST-1 located in the jet, 80 pc away from the M87 core. I analyzed 15 epochs of the 2cm VLBA data and performed wide-field imaging, which allowed me to detect HST-1 for the first time at 15GHz using VLBI observations. I am also interested in the multi-wavelength properties of AGNs, and I worked on the broadband spectral energy distribution (SED) properties of MOJAVE, which is a complete sample of blazars. This was done collecting data from the the radio to the gamma-ray band for 135 AGN, and combining the results of the SED fitting with their VLBI properties. We found that AGNs with higher jet speed also have higher frequency peaks in their broadband SEDs. ​

Master of Science in Astronomy​

I started my first research project of astronomy at the Institute of Astronomy in the National Tsing Hua University in Taiwan. I was working with Professor Dean-Yi Chou on astroseismology. My master thesis "Preliminary Data Reduction of Asteroseismic Data from the EAST Network and Light Curves of GN And" addresses the data reduction software I developed using C language for processing the data observed by the Earthshine and Asteroseismology Telescope (East) Network.
