    DESI Emission-line Galaxies: Unveiling the Diversity of [O II] Profiles and Its Links to Star Formation and Morphology
    We study the [O II] profiles of emission-line galaxies (ELGs) from the Early Data Release of the Dark Energy Spectroscopic Instrument (DESI). To this end, we...

    Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations
    Lyman-break galaxy (LBG) candidates at z ≳ 10 are rapidly being identified in James Webb Space Telescope (JWST)/NIRCam observations. Due to the (redshifted)...

    JWST/NIRCam Narrowband Survey of Paβ Emitters in the Spiderweb Protocluster at z = 2.16
    We report the initial result of our Paβ narrowband imaging on a protocluster with the JWST Near Infrared Camera (NIRCam). As NIRCam enables deep narrowband...

    JWST/NIRCam Paβ Narrowband Imaging Reveals Ordinary Dust Extinction for Hα Emitters within the Spiderweb Protocluster at z = 2.16
    We combine JWST/NIRCam and Subaru/MOIRCS dual Paβ+Hα narrowband imaging to trace the dust attenuation and the star formation activities of a sample of 43 Hα...

    MIGHTEE-HI: Evolution of HI Scaling Relations of Star-forming Galaxies at z < 0.5
    We present the first measurements of H I galaxy scaling relations from a blind survey at z > 0.15. We perform spectral stacking of 9023 spectra of star-forming...
