    Early-type Galaxies with Tidal Debris and Their Scaling Relations in the Spitzer Survey of Stellar Structure in Galaxies (S4G)
    Tidal debris around galaxies can yield important clues on their evolution. We have identified tidal debris in 11 early-type galaxies (T

    Effect of the initial mass function on the dynamical SMBH mass estimate in the nucleated early-type galaxy FCC 47
    Supermassive black holes (SMBHs) and nuclear star clusters (NSCs) co-exist in many galaxies. While the formation history of the black hole is essentially lost...

    Electron densities of HII regions throughout the NGC 6946 disk
    We have used the tuneable filter system of OSIRIS to observe the [SII] doublet lines at λλ617.7 and 673.1 nm in emission across the full face of NGC 6946, and...

    Electron temperature fluctuations in Seyfert galaxies
    We use Gemini GMOS-IFU observations of three luminous nearby Seyfert galaxies (Mrk 79, Mrk 348, and Mrk 607) to estimate the electron temperature (T e)...
