Book excerpt: This dissertation introduces the Dark Matter (DM) Radio, a tunable, lumped-LC oscillator search for axion and hidden-photon dark matter between 1 peV and 1 ueV. The design of DM Radio is motivated from fundamental statements regarding impedance-matching to dark matter and optimal electromagnetic searches for axions and hidden photons subject to the Standard Quantum Limit (SQL) on phase-insensitive amplification. I describe the DM Radio Pathfinder, a prototype detector searching for hidden-photon dark matter between 400 peV and 40 neV. First data from the Pathfinder are presented. I propose the Radio-Frequency Quantum Upconverter (RQU), a device which enables DM Radio readout sensitivity beyond the SQL. The ultimate vision for DM Radio, a cubic-meter-volume resonant experiment operating at 10 mK with a 4 Tesla DC magnetic field and exploiting quantum metrology, is presented. This experiment will enable a probe of the QCD axion between 4 neV and 1 ueV.

Book excerpt: Based on the landmark Radio 4 series, this beautifully illustrated modern history of the connections between science and art offers a new perspective on what that relationship has contributed to the world around us. __________ Throughout history, artists and scientists have been driven by curiosity and the desire to experiment. Both have wanted to make sense of the world around them, often to change it, sometimes working closely together, certainly taking inspiration from each other's disciplines. The relationship between the two has traditionally been perceived as one of love and hate, fascination and revulsion, symbiotic but antagonistic. But art is crucial to helping us understand our science legacy and science is well served by applying an artistic lens. How exactly has the ingenuity of science and technology been incorporated into artistic expression? And how has creative practice, in turn, stimulated innovation and technological change? The Art of Innovation is a history of the past 250 years viewed through the disciplines of art and science. Through fascinating stories that explore the sometimes unexpected relationships between famous artworks and significant scientific and technological objects - from Constable's cloudscapes and the chemist who first measured changes in air pressure, to the introduction of photography and the representation of natural history in print - it offers a new way of seeing, studying and interpreting the extraordinary world around us.

Download or read book The Dark Matter Problem written by Robert H. Sanders and published by Cambridge University Press. This book was released on 2010-04-22 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most astronomers and physicists now believe that the matter content of the Universe is dominated by dark matter: hypothetical particles which interact with normal matter primarily through the force of gravity. Though invisible to current direct detection methods, dark matter can explain a variety of astronomical observations. This book describes how this theory has developed over the past 75 years, and why it is now a central feature of extragalactic astronomy and cosmology. Current attempts to directly detect dark matter locally are discussed, together with the implications for particle physics. The author comments on the sociology of these developments, demonstrating how and why scientists work and interact. Modified Newtonian Dynamics (MOND), the leading alternative to this theory, is also presented. This fascinating overview will interest cosmologists, astronomers and particle physicists. Mathematics is kept to a minimum, so the book can be understood by non-specialists.

Book excerpt: January 1937. Clouds of war are gathering over a fogbound London. Twenty-eight year old Jack is poor, lonely and desperate to change his life. So when he's offered the chance to be the wireless operator on an Arctic expedition, he jumps at it. Spirits are high as the ship leaves Norway: five men and eight huskies, crossing the Barents Sea by the light of the midnight sun. At last they reach the remote, uninhabited bay where they will camp for the next year. Gruhuken. But the Arctic summer is brief. As night returns to claim the land, Jack feels a creeping unease. One by one, his companions are forced to leave. He faces a stark choice. Stay or go. Soon he will see the last of the sun, as the polar night engulfs the camp in months of darkness. Soon he will reach the point of no return - when the sea will freeze, making escape impossible. And Gruhuken is not uninhabited. Jack is not alone. Something walks there in the dark.

Download or read book The Dark Matter Recordings written by Philip Strackbein and published by Fulton Books, Inc.. This book was released on 2021-06-24 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: Philip is a Christian who works for NASDA and is in charge of the Hobble Telescope. He makes some filters for the telescope that enable him to view the dark matter that exists in the universe. Then he discovers that the dark matter, which has the shape of ovals, have been video-recording everything that has ever happened in the universe. He learns how to access these recordings. The first thing he views is the creation of the world. After the creation of man, there was a population explosion that caused the whole Earth to be filled in a relatively short period of time. Just think what would happen if everyone, having the same intelligence that we have, lived to be eight hundred to nine hundred years old and there was no birth control! Who stops to think that Cain and Abel would have been over a hundred years old at the time that Cain killed Abel and that Eve would have had over fifty more children by that time and that the population of the world by that time could have been over ten thousand? A large portion of the novel presents the five hundred years of Noah's life before the Great Flood. The novel, without violating Scripture, shows that mankind before the flood was very advanced in technology. It proposes a very different explanation for the existence of UFOs than most people imagine. Human beings living on the Earth had succeeded in finding a way to overcome gravity and inertia, had traveled to outer space, and had established colonies on the moon and Mars! The novel contains a great deal of romance and has a surprise ending. 1

Before a man he’s never met smiles down at him and says, “Welcome back, my friend.” In this world he’s woken up to, Jason’s life is not the one he knows. His wife is not his wife. His son was never born. And Jason is not an ordinary college professor but a celebrated genius who has achieved something remarkable. Something impossible. Is it this life or the other that’s the dream? And even if the home he remembers is real, how will Jason make it back to the family he loves? From the bestselling author Blake Crouch, Dark Matter is a mind-bending thriller about choices, paths not taken, and how far we’ll go to claim the lives we dream of.

Download or read book Radio for Hidden photon Dark Matter Detection written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We propose a resonant electromagnetic detector to search for hidden-photon dark matter over an extensive range of masses. Hidden-photon dark matter can be described as a weakly coupled ?hidden electric field,? oscillating at a frequency fixed by the mass, and able to penetrate any shielding. At low frequencies (compared to the inverse size of the shielding), we find that the observable effect of the hidden photon inside any shielding is a real, oscillating magnetic field. We outline experimental setups designed to search for hidden-photon dark matter, using a tunable, resonant LC circuit designed to couple to this magnetic field. Our ?straw man? setups take into consideration resonator design, readout architecture and noise estimates. At high frequencies, there is an upper limit to the useful size of a single resonator set by 1/?. However, many resonators may be multiplexed within a hidden-photon coherence length to increase the sensitivity in this regime. Hidden-photon dark matter has an enormous range of possible frequencies, but current experiments search only over a few narrow pieces of that range. As a result, we find the potential sensitivity of our proposal is many orders of magnitude beyond current limits over an extensive range of frequencies, from 100 Hz up to 700 GHz and potentially higher.

Download or read book The Isotropic Radio Background and Annihilating Dark Matter written by and published by . This book was released on 2012 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations by ARCADE-2 and other telescopes sensitive to low frequency radiation have revealed the presence of an isotropic radio background with a hard spectral index. The intensity of this observed background is found to exceed the flux predicted from astrophysical sources by a factor of approximately 5-6. In this article, we consider the possibility that annihilating dark matter particles provide the primary contribution to the observed isotropic radio background through the emission of synchrotron radiation from electron and positron annihilation products. For reasonable estimates of the magnetic fields present in clusters and galaxies, we find that dark matter could potentially account for the observed radio excess, but only if it annihilates mostly to electrons and/or muons, and only if it possesses a mass in the range of approximately 5-50 GeV. For such models, the annihilation cross section required to normalize the synchrotron signal to the observed excess is sigma v ̃(0.4-30) x 10-̂26 cm3̂/s, similar to the value predicted for a simple thermal relic (sigma v ̃3 x 10-̂26 cm3̂/s). We find that in any scenario in which dark matter annihilations are responsible for the observed excess radio emission, a significant fraction of the isotropic gamma ray background observed by Fermi must result from dark matter as well.
