... This calibration approach is recommended when dealing with high frequency data from the old ATCA correlator, especially at 3mm wavelengths. ... The approach described here exploits the dual frequency bands that were available with the old correlator. ... Rather the current approach assumes that you have a single Miriad dataset containing bandpass calibrator, phase calibrator, flux density calibrator and program source. ... MFCAL . ...

... Credit: Mischa Schirmer Explanation: What's happening to galaxy NGC 474? ... The cause of the shells is currently unknown, but possibly tidal tails related to debris left over from absorbing numerous small galaxies in the past billion years. Alternatively the shells may be like ripples in a pond, where the ongoing collision with the spiral galaxy to the right of NGC 474 is causing density waves to ripple though the galactic giant. ...

Astronomers using NASA's Hubble Space Telescope have ruled out an alternate theory on the nature of dark energy after recalculating the expansion rate of the universe to unprecedented accuracy. ... The Hubble observations were conducted by the Supernova Ho for the Equation of State (SHOES) team that works to refine the accuracy of the Hubble constant to a precision that allows for a better characterization of dark energy's behavior...

Next: Sky Subtraction Up: Construction of Flat Previous: Standard construction . For a number of projects where very deep integrations and accurate flat fields are required, and the targets are point sources or much smaller than the frame size, the sky background itself can be used to calculate the flat field. ... Use STATISTICS/IMAGE to calculate the image median, and COMPUTE/IMAGE to divide by this to get the normalised flat field. ...

... The parameter pgdev allows the user to specify a pgplot device, but, in contrast to the pgplot standard, the file name should not be included, but instead supplied via the parameter plotfile . ... To write a colour postscript file called op.ps: pgdev=/cps plotfile=op.ps . However note that at present, if a colour postscript device ( pgdev = `/cps'), a fits file ( pgdev = `/fits') or a ppm file ( pgdev = `/ppm') are selected, the task in fact bypasses pgplot and writes the postscript file directly. ...

To Solve Dark Matter Problem Without Dark Matter Chongming Xu Lohrmann Observatory, Dresden, Germany In this paper, we point out the main character of dark matter: invisible and dissipationless (or fully transparent) to be the same as the one of the gravitational eld. There are several alternative gravitational theories to revise general relativity and Newtonian law to explain the rotation curve of the spiral galaxies without dark matter. ...

... The distribution of galactic RCB stars is controversial. Several authors have argued that they belong to a thick galactic disk, and are thus old Population I stars. ... However, their distribution and space velocities suggest they may alternatively belong to the even older galactic bulge (Population II, [ Drilling 1986 ]). ... These are the only RCB stars for which a distance is known and hence for which an absolute magnitude can be deduced. ...
