What drives the HI content of central galaxies -- A comparison between hydrodynamic simulations and observations using Random Forest
Xiao Li, Cheng Li, Houjun Mo
We investigate the driving mechanisms for the HI gas content in star-forming central galaxies at low redshift, by examining the HI-to-stelalr mass ratio () in bo…
Post-starburst galaxies in SDSS-IV MaNGA: Two broad categories of evolutionary pathways
Zhuo Cheng, Cheng Li, Niu Li +2
We study the size-mass relation (SMR) and recent star formation history (SFH) of post-starburst (PSB) galaxies in the local Universe, using spatially resolved spectroscopy from the…
On the existence, rareness and uniqueness of quenched HI-rich galaxies in the local Universe
Xiao Li, Cheng Li, H. J. Mo +3
Using data from ALFALFA, xGASS, HI-MaNGA and the Sloan Digital Sky Survey (SDSS), we identify a sample of 47 "red but HI-rich"(RR) galaxies with and unusually high HI-t…
SDSS-IV MaNGA: Bayesian analysis of the star formation history of low-mass galaxies in the local Universe
Shuang Zhou, H. J. Mo, Cheng Li +2
We measure the star formation histories (SFH) of a sample of low-mass galaxies with from the SDSS-IV MaNGA survey. The large number of IFU spectra for each gal…
SDSS-IV MaNGA: Stellar initial mass function variation inferred from Bayesian analysis of the integral field spectroscopy of early type galaxies
Shuang Zhou, H. J. Mo, Cheng Li +7
We analyze the stellar initial mass functions (IMF) of a large sample of early type galaxies (ETGs) provided by MaNGA. The large number of IFU spectra of individual galaxies provid…
SDSS-IV MaNGA: Global stellar population and gradients for about 2000 early-type and spiral galaxies on the mass-size plane
Hongyu Li, Shude Mao, Michele Cappellari +12
We perform full spectrum fitting stellar population analysis and Jeans Anisotropic modelling (JAM) of the stellar kinematics for about 2000 early-type galaxies (ETGs) and spiral ga…
