    Large scale structures and galaxy evolution in the COSMOS Survey
    The COSMOS survey is the largest high redshift galaxy evolution survey ever done -- imaging 2 square degrees with all major space-based and ground based...

    Localized starbursts in dwarf galaxies produced by impact of low metallicity cosmic gas clouds
    Models of galaxy formation predict that gas accretion from the cosmic web is a primary driver of star formation over cosmic history. Except in very dense...

    Luminosity and Stellar Mass Functions of Faint Photometric Satellites around Spectroscopic Central Galaxies from DESI Year-1 Bright Galaxy Survey
    We measure the luminosity functions (LFs) and stellar mass functions (SMFs) of photometric satellite galaxies around spectroscopically identified isolated...

    Lyα Emitting Galaxies (LAEs) at Cosmic Dawn: Implications and Predictions
    The detection of Lyα emitting galaxies (LAEs) puts severe constraints on the reionization history. In this paper, we derive the properties of very high-z LAEs...

    Magnetic turbulence hidden in the Whirlpool Galaxy
    There is a force hidden deep inside galaxies: magnetic fields. Invisible to conventional telescopes, they are a factor in galaxy evolution, regulating the...

    Measuring a Galaxy: Morphology, Mass, Environment and Evolution
    What can the shape and size of a galaxy tell us about how it has evolved across cosmic time? Which evolutionary mechanisms are important, or relevant, and which...

    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...

    Negative feedback in the most powerful active galaxies - NO STREAMING -
    Evidence for an intimate connection between supermassive black hole (SMBH) growth and the evolution of galaxies is nowadays compelling. Not only have SMBHs been...

    NGDEEP Epoch 1: Spatially Resolved Hα Observations of Disk and Bulge Growth in Star-forming Galaxies at z ∼ 0.6–2.2 from JWST NIRISS Slitless Spectroscopy
    We study the Hα equivalent width (EW(Hα)) maps of 19 galaxies at 0.6 < z < 2.2 in the Hubble Ultra Deep Field using NIRISS slitless spectroscopy as part of the...
