Near Infrared

- Keck

I am currently working on the NSF-funded AGN project (PI: Prof. Anne Medling). My work focuses on analyzing OSIRIS data, including improving the mosaics and studying the gas and stellar kinematics. I plan to build a dynamical mass model to test the modified Bondi SMBH accretion as well as accretion driven by gravitational torques.

- Very Large Telescope (VLT)

The VLT Large Program (PI: Dr. Richard Davies) goes into individual ESO observation period (93P, 98P, and 99P). My works include preparing the observation blocks (OBs), doing the data reduction, and improving the calibration pipeline. In order to retrieve higher S/N ratio in absorption lines, I reduce the effects of differential atmospheric refraction by theoretical calculation in the both the image and spectroscopy. Such effect becomes significant for high-resolution observations (e.g. AO mode) at near-infrared wavelengths.

Radio

- Institut de Radioastronomie Millimétrique (IRAM)

I studied HCN and HCO⁺ emission in the nuclear regions of nearby AGNs using data from the Plateau de Bure Interferometer (PdBI). Recently, I have been using the new NOEMA-PolyFix instrument to observe CO gas kinematics and investigate AGN feedback mechanisms.

- Yuan-Tseh Lee Array (YTLA)

It is a 7 small dishes interferometer project leaded by Taiwan (former name:AMiBA). I assist daytime and nighttime observing and work closely with engineers/project scientist to do the troubleshooting, for example: decompose the antennae amplitudes and looking for whether they correlate to the instrumental temperatures. I also measure the quasar continuum flux density, then compare to the System Equivalent Flux Density (SEFD) in order to check the instrument stability, it is a part of commissioning test and verification phases. (On site during Aug 2018, Oct-Dec 2018).

- Submillimeter Array (SMA)

My first professional astronomy research is using SMA data to study the shell kinematics of post-AGB star. I used MIR and MIRID to flag out bad data and reconstruct the image. I also complete one night observation for the summer student group project – searching the methanol signal from high-z galaxy.

Optical

- Binocular Telescope (LBT)

The science program belongs to Dr. Eva Wuyts. I was a volunteer student to work with instrument scientists and telescope operators. In the six-day observations, my works included assisting the observing program execution, assessing weather condition, communicating with LBTO staff.
