Identifying protoclusters in distant universe
Astronomische Nachrichten, 2021AbstractProperties of galaxies, such as color, age, and star formation activity, appear to be associated with the environment in which they are immersed. To investigate how the environment‐galaxy relation is established, we study protoclusters, which are numerically dense environments of galaxies in the early Universe, and which give rise to galaxy ...

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 ...

Galaxy protocluster candidates at 1.6
2010We present a study of protoclusters associated with high redshift radio galaxies. We imaged MRC1017-220 (z=1.77) and MRC0156-252 (z=2.02) using the near-infrared wide-field (7.5'x7.5') imager VLT/HAWK-I in the Y, H and Ks bands. We present the first deep Y-band galaxy number counts within a large area (200 arcmin2).

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.
