Supernova

C. A. Higgins’s acclaimed novel Lightless fused suspenseful storytelling, high-caliber scientific speculation, and richly developed characters into a stunning science fiction epic. Now the dazzling Supernova heightens the thrills and deepens the haunting exploration of technology and humanity—and the consequences that await when the two intersect. Once Ananke was an experimental military spacecraft. But a rogue computer virus transformed it—her—into something much more: a fully sentient artificial intelligence, with all the power of a god—and all the unstable emotions of a teenager. Althea, the ship’s engineer and the last living human aboard, nearly gave her life to save Ananke from dangerous saboteurs, forging a bond as powerful as that between mother and daughter. Now she devotes herself completely to Ananke’s care. But teaching a thinking, feeling machine—perhaps the most dangerous force in the galaxy—to be human proves a monumental challenge. When Ananke decides to seek out Matthew Gale, the terrorist she regards as her father, Althea learns that some bonds are stronger than mortal minds can understand—or control. Drawn back toward Earth by the quest, Althea and Ananke will find themselves in the thick of a violent revolution led by Matthew’s sister, the charismatic leader Constance, who will stop at nothing to bring down a tyrannical surveillance state. As the currents of past decisions and present desires come into stark collision, a new and fiery future is about to be born. Praise for Supernova “An enjoyable, hard science fiction adventure.”—Cinelinx “Higgins succeeds in expanding her universe and leaving the reader hungry to learn how her debut trilogy will end.”—New York Daily News “Riveting and thought-provoking.”—Publishers Weekly Praise for C. A. Higgins’s Lightless “Gripping . . . sci-fi with a hint of thriller.”—New York Daily News “[A] measured, lovely science-fiction debut [that is] more psychological thriller . . . contained, disciplined, tense . . . The plot is compulsive. . . . Lightless is the first of a planned series, and you can’t help looking forward to learning what’s next.”—The New York Times “The stakes in this story are high—life and death, rebellion and betrayal. . . . Higgins continually ratchets up the tension. . . . This is a debut not to be missed.”—Kirkus Reviews (starred review) “A taut, suspenseful read.”—Tech Times “Absolutely brilliant . . . science fiction as it is meant to be done.”—New York Times bestselling author Seanan McGuire

Extremely Fast Acceleration of Cosmic Rays in a Supernova Remnant

Galactic cosmic rays (CRs) are widely believed to be accelerated by shock waves associated with the expansion of supernova ejecta into the interstellar medium. A key issue in this long-standing conjecture is a theoretical prediction that the interstellar magnetic field can be substantially amplified at the shock of a young supernova remnant (SNR) through magnetohydrodynamic waves generated by cosmic rays. Here we report a discovery of the brightening and decay of X-ray hot spots in the shell of theSNRRXJ1713.723946 on a one-year timescale. This rapid variability shows that the X-rays are produced by ultrarelativistic electrons through a synchrotron process and that electron acceleration does indeed take place in a strongly magnetized environment, indicating amplification of the magnetic field by a factor of more than 100. The X-ray variability also implies that we have witnessed the ongoing shock-acceleration of electrons in real time. Independently, broadband X-ray spectrometric measurements of RXJ1713.723946 indicate that electron acceleration proceeds in the most effective ('Bohm-diffusion') regime. Taken together, these two results provide a strong argument for acceleration of protons and nuclei to energies of 1 PeV (1015 eV) and beyond in young supernova remnants.

Supernova Remnants And GLAST.

It has long been speculated that supernova remnants represent a major source of cosmic rays in the Galaxy. Observations over the past decade have ceremoniously unveiled direct evidence of particle acceleration in SNRs to energies approaching the knee of the cosmic ray spectrum. Nonthermal X-ray emission from shell-type SNRs reveals multi-TeV electrons, and the dynamical properties of several SNRs point to efficient acceleration of ions. Observations of TeV gamma-ray emission have confirmed the presence of energetic particles in several remnants as well, but there remains considerable debate as to whether this emission originates with high energy electrons or ions. Equally uncertain are the exact conditions that lead to efficient particle acceleration. Based on the catalog of EGRET sources, we know that there is a large population of Galactic gamma-ray sources whose distribution is similar to that of SNRs. With the increased resolution and sensitivity of GLAST, the gamma-ray SNRs from this population will be identified. Their detailed emission structure, along with their spectra, will provide the link between their environments and their spectra in other wavebands to constrain emission models and to potentially identify direct evidence of ion acceleration in SNRs. Here I summarize recent observational and theoretical work in the area of cosmic ray acceleration by SNRs, and discuss the contributions GLAST will bring to our understanding of this problem.

Gamma-ray Emission from Crushed Clouds in Supernova Remnants

It is shown that the radio and gamma-ray emission observed from newly-found 'GeV-bright' supernova remnants (SNRs) can be explained by a model, in which a shocked cloud and shock-accelerated cosmic rays (CRs) frozen in it are simultaneously compressed by the supernova blastwave as a result of formation of a radiative cloud shock. Simple reacceleration of pre-existing CRs is generally sufficient to power the observed gamma-ray emission through the decays of [pi]°-mesons produced in hadronic interactions between high-energy protons (nuclei) and gas in the compressed-cloud layer. This model provides a natural account of the observed synchrotron radiation in SNRs W51C, W44 and IC 443 with flat radio spectral index, which can be ascribed to a combination of secondary and reaccelerated electrons and positrons.
