• New research progress in spin alignments of spiral galaxies within the large-scale structure

    In the current universe, large scale environments are mainly consists of these four types: clusters, filaments, sheets and voids. According to the current paradigm of galaxy formation, these structures arise from the linear growth of density fluctuations in a nearly homo

  • Measure the average cosmic dust density using quasar continuum

    Cosmic dust —— dust in space—— includes intergalactic dust, interstellar dust, interplanetary dust and circumplanetary dust, which can cause not only extinction but also reddening for the remote background objects. Cosmic dust extinction plays a very important role in cosmological study. For example, the existence of cosmic...
