... Planck Maps the Microwave Background . ... Credit Copyright: European Space Agency , Planck Collaboration Explanation: What is our universe made of? To help find out, ESA launched the Planck satellite to map, in unprecedented detail, slight temperature differences on the oldest surface known -- the background sky left billions of years ago when our universe first became transparent to light. ...

... The active time at each angular bin is the sum over frames of the active time contributions from all CCD pixels, within the node-specific telemetry window, which overlap the surface of the bin. ... The active time, per frame, of a normal pixel is the full frame integration time multiplied by the node-specific fractional exposure; bad pixels contribute no active time. ... If an event is rejected for this reason only, then its pixels remain normal in the exposure map. ...

home publications > mercury . ... The Universe in the Classroom . ... Decoding the Mystery of Dark Energy . ... About 70% of the universe?s energy consists of a force that accelerates cosmic expansion, and scientists know virtually nothing about it. ... Using Type Ia supernovae, which result from the thermonuclear explosions of white dwarfs locked in binary systems (see "Searching for Supernovae To Be," Jan/Feb 2003 ), the teams were able to determine the recent expansion history of the universe. ...

... Dark energy is believed to be a component of the Universe whose repulsive gravity is presently accelerating the expansion of the Universe.€а Although it comprises the bulk of the mass-energy of the Universe, its nature is not well understood.€а €аAlbert Einstein originally suggested its existence about 80 years ago. A supernova is the explosive death of a star, which unleashes a burst of light through the cosmos. ... This website is a gift from Nancy Riess . ...

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

As the tired, hackneyed refrains went on, one in particular caught my ear: " Fly me away to the bright side of the moon, and meet me on the other side." ... As the Moon orbits the Earth, different parts of it get illuminated by the Sun. ... Bad Addendum : At the end of the album "Dark Side of the Moon" by Pink Floyd, there is a voiceover that actually says "There is no dark side of the moon. ...

Next: *imcalc* - Obtain a Up: Calibration Previous: Exposure Map . Background maps are provided by the standard processing for all ROSAT and Einstein instruments. For the PSPC and IPC these are in three standard bands: soft, hard, and broad (Table 6.2). ... N.B.: ROSAT PSPC background maps in SASS 5-6 or higher are generated by smoothing a source-subtracted, exposure corrected image (see the ROSAT Data Products Guide). ... imcalc* - Obtain a background subtracted image for ROSAT PSPC Data . ...

... The first EGRET catalog ([ Fichtel et al. 1994b ]) used the galactic diffuse gamma radiation model of Bertsch et al. (1993b). ... For the results presented by Bertsch et al. (1993b), the HI and W radio data were deconvolved by integrating the radio data over a velocity interval determined by the endpoints of each distance interval ( ). ... The Galactic radius limit used in the model has been increased to 30 kpc. ... The CR electron spectrum of Fichtel et al. (1991) was used by Bertsch et al. ...

... 2005: . Using the radio telescope GMRT (India) and the 6 m telescope of SAO RAS, maps of the distribution of neutral and ionized hydrogen have been obtained in 60 nearby dwarf galaxies whose luminosities range from 1/100 to 1/10000 of that of the Milky Way. ...
