W. F. Frya first part, I introduce the concept of ‘ecological novelty’ to characterise ongoing environmental change. The environmental change that brings about ecological novelty can be characterised by at least six attributes: it is (1) man-made, (2) large, (3) very fast, (4) multi-dimensional, (5) variable作者: attenuate 時(shí)間: 2025-3-22 18:28

High Energy Radiation from the Young PulsarsThe young pulsars, typified by the Crab and Vela Pulsars, are distinguished by their short periods and large rates of period increase. The category does not include the “millisecond” pulsars, which have very small rates of period increase: these are old pulsars, whose high spin rates are the result of a spin-up process in a binary system.作者: 刀鋒 時(shí)間: 2025-3-26 22:37

Further Evidence for the Emission of 1000 GeV Gamma Rays with 12 ms Periodicity from Cygnus X-3The X-ray binary Cygnus X-3 has long been suspected of containing a young fast pulsar and the first evidence for this, suggesting a period of 12.59 ms, was reported by us in 1985. We here report further evidence for the reality of the 12.59 ms periodicity and indications of value for the secular derivative for the period.作者: watertight, 時(shí)間: 2025-3-27 18:20
