    Emergence of an Ultrared, Ultramassive Galaxy Cluster Core at z = 4
    Recent simulations and observations of massive galaxy cluster evolution predict that the majority of stellar mass buildup happens within cluster members by z =...

    Environmental Quenching of Low-surface-brightness Galaxies Near Hosts from Large Magellanic Cloud to Milky Way Mass Scales
    Low-surface-brightness galaxies (LSBGs) are excellent probes of quenching and other environmental processes near massive galaxies. We study an extensive sample...

    Evidence for a Shallow Evolution in the Volume Densities of Massive Galaxies at z = 4–8 from CEERS
    We analyze the evolution of massive (log 10[M ⋆/M ⊙] > 10) galaxies at z ∼ 4–8 selected from JWST Cosmic Evolution Early Release Survey (CEERS). We infer the...

    Evidence for secular evolution of disc structural parameters in barred galaxies
    I will address the effects of bar-driven secular evolution in discs by comparing their properties in a sample of nearly 700 barred and unbarred massive galaxies...

    Evolution of the Mass-Metallicity Relation from Redshift z ≈ 8 to the Local Universe
    A tight positive correlation between the stellar mass and the gas-phase metallicity of galaxies has been observed at low redshifts. The redshift evolution of...

    Evolution of the Size–Mass Relation of Star-forming Galaxies Since z = 5.5 Revealed by CEERS
    We combine deep imaging data from the CEERS early release JWST survey and Hubble Space Telescope imaging from CANDELS to examine the size–mass relation of star...

    Evolutionary paths of the most massive galaxies since z ~ 2
    Observations have shown that massive galaxies at high redshift have much smaller sizes than galaxies of similar mass today. The mean stellar density of such...

    Exploring the local universe with massive stars
    Massive stars dominate the light output of entire galaxies, with luminosities in excess of 10 5 L⊙. This makes them powerful probes with which to study a range...

    Extended Point-spread Functions for Deep Astronomical Imaging Surveys
    The low surface brightness (LSB) universe is one of the last frontiers in observational astronomy. However, uncovering the information contained in ultra-deep...
