Research Highlight
Galaxy Interaction
- Search the isolated compact galaxy systems, such as galaxy pairs (Shen et al. 2015,Feng et al. 2019), galaxy triplets (Feng et al. 2016), and galaxy groups (Zheng et al. 2022), based on SDSS Main Galaxy Sample. Through supplementing a large number of spectral redshifts from other surveys (e.g. LAMOST, GAMA), the completeness significantly increases.
- Calculate the bivariate luminosity function of galaxy pairs, which provides the complete description of the luminosity of galaxy pairs in the low-z universe and statistical constraints for the merging timescale and starburst timescale (Feng et al. 2019).
Kinematics of Ionized Gas
- Detect the correlation between star formation enhancement and disturbed velocity maps of ionized gas in galaxy pairs (Feng et al. 2020), indicating that the kinematic asymmetry (the asymmetric degree of velocity map morphology) is a good indicator of galaxy merging phase (Yu et al. 2022).
- Make a census on the kinematic asymmetry of ionized gas in the local universe based on the data of SDSS-IV MaNGA survey, and unveil that the regular galaxies dominate the population with high kinematic asymmetry(Feng et al. 2022).
Simulation of IFS Datacube
- Develop gehong package to simulate the datacube observed by the integral field spectrometer on board the Chinese Space Station telescope (CSST-IFS).
