SDSS-IV MaNGA: Star Formation Cessation in Low-redshift Galaxies. I. Dependence on Stellar Mass and Structural Properties (2018)
Journal Article
Riffel, R., Wang, E., Li, C., Xiao, T., Lin, L., Bershady, M., …Yan, R. (in press). SDSS-IV MaNGA: Star Formation Cessation in Low-redshift Galaxies. I. Dependence on Stellar Mass and Structural Properties. Astrophysical Journal, 856(2), https://doi.org/10.3847/1538-4357/aab263

We investigate radial gradients in the recent star formation history (SFH) of 1917 MaNGA galaxies with 0.01 < z < 0.14. For each galaxy, we obtain two-dimensional maps and radial profiles for three spectroscopically-measured parameters that are sensi...

The growth of the central region by acquisition of counterrotating gas in star-forming galaxies (2016)
Journal Article
Chen, Y., Shi, Y., Tremonti, C. A., Bershady, M., Merrifield, M., Emsellem, E., …Yan, R. (2016). The growth of the central region by acquisition of counterrotating gas in star-forming galaxies. Nature Communications, 7, Article 13269. https://doi.org/10.1038/ncomms13269

Galaxies grow through both internal and external processes. In about 10% of nearby red galaxies with little star formation, gas and stars are counter-rotating, demonstrating the importance of external gas acquisition in these galaxies. However, syste...

SDSS-IV MaNGA: properties of galaxies with kinematically decoupled stellar and gaseous components (2016)
Journal Article
Jin, Y., Chen, Y., Shi, Y., Tremonti, C. A., Bershady, M. A., Merrifield, M., …Yan, R. (2016). SDSS-IV MaNGA: properties of galaxies with kinematically decoupled stellar and gaseous components. Monthly Notices of the Royal Astronomical Society, 463(1), 913-926. https://doi.org/10.1093/mnras/stw2055

We study the properties of 66 galaxies with kinematically misaligned gas and stars from MaNGA survey. The fraction of kinematically misaligned galaxies varies with galaxy physical parameters, i.e. M*, SFR and sSFR. According to their sSFR, we further...

P-MaNGA: gradients in recent star formation histories as diagnostics for galaxy growth and death (2015)
Journal Article
Li, C., Wang, E., Lin, L., Bershady, M. A., Bundy, K., Tremonti, C., …Zheng, T. (2015). P-MaNGA: gradients in recent star formation histories as diagnostics for galaxy growth and death. Astrophysical Journal, 804(2), 125. https://doi.org/10.1088/0004-637x/804/2/125

We present an analysis of the data produced by the MaNGA prototype run (P-MaNGA), aiming to test how the radial gradients in recent star formation histories, as indicated by the 4000 ??break (Dn(4000)), H? absorption (EW(H?A)), and H? emission (EW(H?...

Virtual sensors for active noise control in acoustic–structural coupled enclosures using structural sensing: robust virtual sensor design (2011)
Journal Article
Halim, D., Cheng, L., & Su, Z. (2011). Virtual sensors for active noise control in acoustic–structural coupled enclosures using structural sensing: robust virtual sensor design. Journal of the Acoustical Society of America, 129(3), https://doi.org/10.1121/1.3531941

The work was aimed to develop a robust virtual sensing design methodology for sensing and active control applications of vibro-acoustic systems. The proposed virtual sensor was designed to estimate a broadband acoustic interior sound pressure using s...
