Reasearch Experience

Studying the Inner Accretion Flows of Black Hole X-ray Binary H 1743-322 with RXTE and NuSTAR Data

Supervisor: Prof. Javier Garcia

Sep 2021 – Present California Institute of Technology

Written six Python scripts with PyXspec to perform automatic spectra fitting with more than 557 RXTE observations of the black hole binary H 1743-322 in the outbursts from 2003 to 2011.
Performed global reflection modeling with relxill model to measure key physical properties like spin and inclination angle with RXTE and NuSTAR data.

Testing the existence of two coronae of the black hole candidate MAXI J1348-630 in the 2019 outburst observed by INSIGHT-HXMT

Supervisor: Prof. Roberto Soria

July. 2021 – Sept. 2021 National Astronomical Observatories, Chinese Academy of Sciences

Reduced the INSIGHT-HXMT observation of the black hole candidate MAXI J1348-630 in the 2019 outburst.
Applied relxill model to test the existence of two coronae to confirm results from QPOs models.

Constraining the KRZ deformation parameters with stellar mass black hole X-ray data

Supervisor: Prof. Cosimo Bambi

Sept. 2020 – June. 2021 Fudan University

Reduced the NuSTAR observation data of stellar mass black hole EXO 1846+031 and applied the non-Kerr metric model relxill_nk to test general relativity with a new metric.
Published a paper on Physical Review D.

Simulations of cosmic ray air shower with different hadronic models

Supervisor: Prof. Antonino Marciano

Sept. 2020 – July 2021 Fudan University

Simulated extensive air showers with CORSIKA software and generated muon lateral distribution histograms with C++ codes.
Applied hadronic model Sibyll 2.3c. Different models are about to be tested.
Planned to apply machine learning techniques to explore parameter space.

Electrical devices based on DNA molecules and their nanostructures

Supervisor: Prof. Dacheng Wei

June 2020 – Oct. 2020 Fudan University

Fabricated a field-effect transistor (FET) with an actuatable liquid-gating sensing interface with DNA electro-actuators (DNA-EAs) manipulated electrostatically at the liquid-gate surface and realized direct detection of SARS-CoV-2 nucleic acids.
Used secondary current distribution module in COMSOL Multiphysics® to simulate the electrical field distribution when an electro-actuation voltage was applied at the gate.
