Accelerated Structure Formation: The Early Emergence of Massive Galaxies and Clusters of Galaxies
The Astrophysical JournalGalaxies in the early Universe appear to have grown too big too fast, assembling into massive, monolithic objects more rapidly than anticipated in the hierarchical Lambda cold dark matter (ΛCDM) structure formation paradigm.

, 1989 In this thesis, radial colour and line strength gradients are investigated, and corresponding stellar population gradients are modelled. Together with the gradients, the morphology of the galaxies in optical and near-infrared colours is analyzed. When investigated in detail, every elliptical galaxy has its own special morphology, but nevertheless the ...

Galaxy Morphological Classification with Zernike Moments and Machine Learning Approaches
The Astrophysical Journal Supplement SeriesClassifying galaxies is an essential step for studying their structures and dynamics. Using GalaxyZoo2 (GZ2) fractions thresholds, we collect 545 and 11,735 samples in nongalaxy and galaxy classes, respectively.
