Neutrino Physics and Astrophysics

The clinical application of those vital court cases used to be prepared to hide many of the box of neutrino physics. In mild of the fast development of curiosity inspired by means of new attention-grabbing effects from the sphere, greater than 1/2 the papers provided listed below are regarding the neutrino mass and oscillations, together with atmospheric and sun neutrino experiences. Neutrino mass and oscillations might indicate the lifestyles of a mass scale many orders of magnitudes better than awarded in present physics and should most likely consultant scientists past the normal version of particle physics.

Impact!: The Threat of Comets and Asteroids

Such a lot scientists now agree that a few sixty-five million years in the past, a major comet slammed into the Yucatan, detonating a blast twenty million occasions extra robust than the biggest hydrogen bomb, punching a gap ten miles deep within the earth. Trillions of hundreds rock have been vaporized and embarked on the ambience.

Here Be Dragons: The Scientific Quest for Extraterrestrial Life

The invention of existence on different planets will be possibly the main momentous revelation in human heritage, extra disorienting and extra profound than both the Copernican or Darwinian revolutions, which knocked the earth from the guts of the universe and humankind from its place of lofty self-regard.

From Cosmos to Chaos: The Science of Unpredictability

Cosmology has gone through a revolution lately. The fascinating interaction among astronomy and basic physics has resulted in dramatic revelations, together with the life of the darkish topic and the darkish strength that seem to dominate our cosmos. yet those discoveries purely demonstrate themselves via small results in noisy experimental facts.

Observing by Hand: Sketching the Nebulae in the Nineteenth Century

This day we're all acquainted with the enduring photographs of the nebulae produced via the Hubble house Telescope’s electronic cameras. yet there has been a time, prior to the winning program of images to the heavens, within which scientists needed to depend on hand-crafted drawings of those mysterious phenomena.           Observing by way of Hand sheds solely new gentle at the ways that the construction and reception of handdrawn photographs of the nebulae within the 19th century contributed to astronomical statement.

This result's acquired after using a history correction to a pattern of 246 quasi-elastic neutrino applicants. due to the fact that our occasion popularity and particle misidentification are varied from these of the water Cerenkov experiments we might no longer inevitably anticipate to degree an identical worth of R. The likelihood of a statistical fluctuation from a real price of one. zero to R=0. sixty four or under is under four x 10 -3. autonomous analyses were performed which money the contained occasion choice, taste decision, and heritage correction approaches of our major research. This dimension is in reliable contract with the formerly released end result from this scan, in addition to the consequences from the water Cerenkov experiments. A 'high-resolution' pattern of occasions has been pointed out which has the potential of precision directional measurements. initial symptoms from this pattern point out strong healthy to v~, ---+ ur might be bought with Am 2 = 10 -2 eV 2 and sin~(20) = 1.
