    Indiana Jones and where to find relic galaxies
    There are galaxies that remain untouched since the ancient Universe. These unique objects, the so-called relic galaxies, are several times more massive than our...

    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...

    Measurements of the Dust Properties in z ≃ 1-3 Submillimeter Galaxies with ALMA
    We present Atacama Large Millimeter/submillimeter Array (ALMA) 2 mm continuum observations of a complete and unbiased sample of 99 870 μm selected submillimeter...

    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...

    On the extreme properties of massive galaxies at high redshifts
    Massive (&#8805 10 11 M⊙) galaxies at high redshift (z &#8805 1.5) remain mysterious objects. Their extremely small sizes (effective radii of 1-2 kpc) make them...

    On the Nature of Disks at High Redshift Seen by JWST/CEERS with Contrastive Learning and Cosmological Simulations
    Visual inspections of the first optical rest-frame images from JWST have indicated a surprisingly high fraction of disk galaxies at high redshifts. Here, we...

    Pieces to the puzzle of high-redshift galaxies
    Our Universe is filled with a mind-blowing diversity and different types and appearances of galaxies. Finding out about how they formed and evolved is one of...

    Probing the early Universe with radio galaxies
    Luminous high-redshift radio galaxies (HzRGs) are associated with the most massive known galaxies in the early Universe. These galaxies have the properties...
