The Origin of Exponential Star-forming Disks
Enci Wang, Simon J. Lilly
The disk components of galaxies generally show an exponential profile extending over several scale lengths, both in mass and star-formation rate, but the physical origin is not wel…
Hosts and triggers of AGNs in the Local Universe
Ziwen Zhang, Huiyuan Wang, Wentao Luo +11
Based on the spectroscopic and shear catalogs for SDSS galaxies in the local Universe, we compare optically-selected active galactic nuclei (AGNs) with control star-forming and qui…
Gas-phase Metallicity as a Diagnostic of the Drivers of Star-formation on Different Spatial Scales
Enci Wang, Simon J. Lilly
We examine the correlations of star formation rate (SFR) and gas-phase metallicity . We first predict how the SFR, cold gas mass and will change with variations in inflow ra…
SDSS-IV MaNGA: the indispensable role of bars in enhancing the central star formation of low- galaxies
Lin Lin, Cheng Li, Cheng Du +8
We analyse two-dimensional maps and radial profiles of EW(H), EW(H), and D(4000) of low-redshift galaxies using integral field spectroscopy from the MaNGA survey. Out o…
The Variability of Star Formation Rate in Galaxies: II. Power Spectrum Distribution on the Main Sequence
Enci Wang, Simon J. Lilly
We constrain the temporal power spectrum of the sSFR(t) of star-forming galaxies, using a well-defined sample of Main Sequence galaxies from MaNGA and our earlier measurements of t…
Characteristic mass in galaxy quenching: environmental versus internal effects
Pengfei Li, Huiyuan Wang, H. J. Mo +2
A clear transition feature of galaxy quenching is identified in the multi-parameter space of stellar mass (), bulge to total mass ratio (), halo mass (…
