The Λ cold dark matter (ΛCDM) model accurately reproduces many notable observations of our Universe, such as the existence of galaxy clusters embedded in a cosmic web. However, there remain many open questions about the physics governing baryons on galaxy cluster scales that the ΛCDM model cannot address, such as how star-formation is triggered and ...

Quasars as protoclusters of galaxies
Astrophysics, 1972A hypothesis is put forward according to which dense bodies (QSG), which occasionally transform into quasars, decay into components and their subsequent fragmentation results in the formation of groups and clusters of galaxies. Recurrent nonthermal radio emission continues during all the subsequent stages of fragmentation and evolution of the QSG's ...

Massive Protostars and Small Protoclusters
2008Recent investigations of massive protostellar candidates in the near-infrared (NIR) wavelengths reveal several 2μm visible embedded clusters, NIR counterparts to massive star precursors and H2 emission in the shape of rings and flared disks around the massive protostars.
