Modern Cosmological Observations and Problems Gregory ~ With new theories and a plethora of data feeding cosmology in the 1990s Gregory Bothun sets about the task of re assessing our cosmological models He outlines exactly what the latest observations are and how they should be seen as either consistent or in conflict with current cosmogenic scenarios
Modern Cosmological Observations and Problems G Bothun ~ In this book we outline some of the most outstanding observational problems associated with our modern cosmological model While much mathematical formalism is essential in order to convey the context of these problems this book is not about exploring the physics of the early Universe or about the details of General Relativity
Modern Cosmological Observations and Problems G Bothun ~ It hass been 30 years since Penzias and Wilson discovered the CMB This observation is the very foundation of the Hot Big Bang cosmological model In its early formulation this model lead to a low density baryon dominated Universe of age 18 billion years Sandage 1982 However with the evidence presented above about the existence of

Modern Cosmological Observations and Problems IOPscience ~ This book describes modern cosmology in a novel way compared with most other textbooks It is framed around observational results rather than the more common approach of being based on theory with occasional support from observations This makes the book much more suitable for observational cosmologists and fills a gap in the market
Modern Cosmological Observations and Problems G Bothun ~ Failing to see any 24 hour modulation of this signal the remaining logical conclusion was that the CMB was indeed of cosmological origin and therefore everywhere Further observations of this CMB showed that its spectral signature was consistent with that of a blackbody as predicted earlier by Gamow
Modern Cosmological Observations and Problems G Bothun ~ 362 Virgocentric Flow Shortly after the detection of the DA Aaronson et al 1980 presented evidence that the determination of H 0 from the distance and observed velocity of the Virgo cluster yielded systematically lower values than using more distant clusters This difference suggested that the observed velocity of Virgo was not equal to its cosmic velocity but instead was a combination
Modern Cosmological Observations and Problems G Bothun ~ where r e is the effective radius defined to enclosed 50 of the light For the high density bulge r e is likely to be less than 2 kpc Gilmore et al 1989 Sackett 1997 For the halo r e lies in the range of 37 kpc Bothun et al 1991 The solar neighborhood lies about 85 kpc from the center of the Galaxy see Sackett 1997 At that distance there are very few if any true bulge stars
The Paradoxes That Threaten To Tear Modern Cosmology Apart ~ The problem with this is that it contradicts one of the basic ideas of modern cosmology—the Hubble law This is the observation that the cosmological redshift of an object is linearly
