Is the Great Attractor Really a Great Wall?
We discuss some of the cosmological consequences of a late-time ( z 5 lo3) phase transition which produces light domain walls. The observed peculiar velocity field of the Universe and the observed isotropy of the microwave background radiation severely constrain the wall surface density (= a) in such a scenario: Go 5 10-4H~ (Ho is the present value of the Hubble parameter). The most interesting...
متن کاملThe Core of the Great Attractor
The nature and extent of the Great Attractor (GA) has been the subject of much debate in the past decade, partly due to the fact that a large fraction of the GA overdensity is hidden by the southern Milky Way. Based on our deep optical galaxy search behind the southern Milky Way and a subsequent redshift survey we discovered that the Norma cluster (ACO 3627) in the GA region is a very massive c...
متن کاملSinonasal Teratocarcinosarcoma- A Rare Tumour not so Rarely Misdiagnosed
Sinonasal teratocarcinosarcoma (STCS) is a rare, morphologically heterogeneous and highly aggressive tumour of ambiguous origin. It is characterized by the presence of benign and malignant epithelial, mesenchymal and neuroectodermal components. Because of their rarity and heterogeneity, these lesions are often misdiagnosed, leading to management difficulties. Adequate sampling with a high index...
متن کاملFalling from Great (and Not-so-great) Heights: How Initial Status Position Influences Performance after Status Loss
We investigate how initial status position influences the quality of task performance in the aftermath of status loss. We argue that despite the benefits of having status, high-status individuals experience more “self-threat”—challenges or contradictions to a central view of the self—and, consequently, have more difficulty performing well after status loss than do low-status individuals who exp...
متن کاملBeta , local SNIa data and the Great Attractor
We compare the measured peculiar velocities of 98 local (< 150h Mpc) type Ia supernovae (SNIa) with predictions derived from the PSCz. There is excellent agreement between the two datasets with a best fit βI (= Ω 0.6 m /bI) of 0.55±0.06. Subsets of the SNIa dataset are further analysed and the above result is found to be robust with respect to culls by distance, host-galaxy extinction and to th...
