We present the first results on the analysis of the structures observed in the jet of the quasar 0836+710. We obtain the ridge lines of the jet at different epochs and several frequencies. We interpret the oscillatory structures obtained as waves that can be attached to the growth of instabilities. We explain how to derive information on the nature and origin of these structures by fitting toge...

The cosmological model best capable of fitting current observational data features two separate epochs during which the Universe is accelerating. During the earliest stages of the Universe, such acceleration is known as cosmological inflation, believed to explain the global properties of the Universe and the origin of structure. Observations of the present state of the Universe strongly suggest...

QUICK FACTS: Rohypnol, known as “roofies” and roaches,” is a sedative-hypnotic drug. Increasing dosages produces signs of progressive central nervous system depression ranging from sedation to sleep. Chronic use of high doses leads to the development of tolerance, but a level of intoxication can always be reached if the dose is high enough. Chronic use of large doses also leads to physical depe...
