... Figure 10: Mean power spectrum obtained by time-averagi ng the energy map at each duration. For non-periodic signals, the mean wavelet spectrum is similar to the Fourier spectrum. ... The compromise we reached in allowing for single bump localization (something Fourier cannot do) reduces the spectral accuracy. ...

... arfgen (arfgen-1.75.6) [?? ... In the case of a point source, arfgen can correct for the flux that is outside the region(s) over which the spectrum was accumulated. ... The correction works by taking a model of the PSF from the CAL, centred at the source position and calculating the total fraction of that PSF within the regions of interest. To enable the encircled energy correction for point sources, the parameter extendedsource must be set to false , as well as modelee being set to true . ...

An investigation of the spectral energy distribution (SED) of the compact steep-spectrum (CSS) source and possible radio-loud narrow-line Seyfert 1 galaxy (NLS1), PKS 2004-447, is presented. ... Analysis of a non-contemporaneous, low-resolution optical spectrum suggests that the narrow-line region (NLR) is much more reddened than the X-ray emitting region suggesting that the gas-to-dust ratio in PKS 2004-447 may be very different than in our own Galaxy. ...

... The low energy plasma composition spectrometer AMEI-2 is built to be able to find in the low energy range of the phase space (E, q, j) and separate the fluxes of the major ion species in the magnetotail - H+, He++, He+ and O+, and analyse their energy and angular distributions. ... Electrostatic angular scanning in one direction and the use of the spin of the satellite to sample the other angle give the ability to measure 2-D distributions for each ion specie several times per spin. ...

... Because binary X-ray sources are strong emitters over a broad range of the electromagnetic spectrum, with each part of the spectrum contributing distinct and often time-variable information, attempts to understand these systems by concentrating on information from a limited wavelength range may lead to contradictory and misleading conclusions. ...

CYGAM, unlike the traditional telescopes, does not have a special energy detector and can not measure energy of each registered photon. ... The physical processes responsible for the high energy gamma-ray emission can not result in narrow lines or sharp irregularities in the energy spectra of compact sources for revelation of which good energy resolution is needed. ...

... Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2009 March 29 . Signals of a Strange Universe . ... Such claims were not usually popular with astronomers, though, because lambda is so unlike known universe components , because lambda's value appeared limited by other observations, and because less- strange cosmologies without lambda had previously done well in explaining the data. ...

... We propose that the bimodal nature of the kick velocity distribu­ tion of radio pulsars is connected to the dichotomy between hadronic stars (i.e. neutron stars with no quark matter content) and quark stars. ... Here we propose a scenario in which the low­velocity part of the distribution is connected with normal (hadronic) compact stars, and high­velocity part is formed by objects with some amount of quark matter inside (hybrid or strange stars). ...
