Possible Inhomogeneities in the Universe on Scales of 100–300 Mpc from Observations with the 6-Meter Telescope

Non-GUT baryogenesis and large-scale structure of the Universe

“…The analysis of other types of observations confirm the existence of this periodicity. Namely, such structure is consistent with the reported periodicity in the distribution of quasars and radio galaxies (Foltz et al 1989, Komberg et al 1996, Quashnock et al 1996, Petitjeau 1996, Cristiani 1998) and Lyman-α forest (Chu & Zhu 1989); the studies on spatial distribution of galaxies (both optical and IRAS) and clusters of galaxies (Kopylov et al 1984, de Lapparent et al 1986, Geller & Hunchra 1989, Hunchra et al 1990, Bertshinger et al 1990, Rowan-Robinson et al 1990, Buryak et al 1994, Bahcall 1992, Fetisova et al 1993a, Einasto et al 1994, Cohen et al 1996, Bellanger & de Lapparent 1995 as well as peculiar velocity information (Lynden-Bell et al 1988, Lauer & Postman 1994, Hudson et al 1999 suggest the existence of a large scale superclusters-voids network with a characteristic scale around 130h −1 Mpc.…”

“…An indication of the presence of this characteristic scale in the distribution of clusters has been found also from the studies of the correlation functions and power spectrum of clusters of galaxies (Kopylov et al 1988, Bahcall 1991, Mo et al 1992, Peacock & West 1992, Deckel et al 1992, Saar et al 1995, Fetisova et al 1993b, Frisch et al 1995, Einasto et al 1997b, Retzlaff et al 1998, Tadros et al 1997. The galaxy correlation function of the Las Campanas redshift survey also showed the presence of a secondary maximum at the same scale and a strong peak in the 2-dimensional power spectrum corresponding to an excess power at about 100 Mpc (Landy et al 1995, Shectman et al 1996, Doroshkevich et al 1996, Geller at al.…”

The supercluster-void network V.

“…One method to characterize this regularity is correlation analysis. Kopylov et al (1984Kopylov et al ( , 1988, Fetisova et al (1993), Mo et al (1992), and Einasto & Gramann (1993) have found evidence for the presence of a secondary peak of the correlation function of clusters of galaxies at 125 h −1 Mpc. This peak has been interpreted as the correlation of clusters in superclusters located at opposite sides of large voids.…”
