Hubble's precision tracking offers a new way to determine a galaxy's rotation by the "sideways" proper motion of its stars, as seen in the plane of the sky. ... By using Hubble to study the stars' motions over several years, we can actually, for the first time, see a galaxy rotate in the plane of the sky," said van der Marel....

These range from the study of nearby planets, the processes of star and planet formation, the stellar and interstellar components of galaxies, the discovery that most, if not all, galactic nuclei harbor a massive black hole that profoundly affects their evolution, to the realisation that the universe as a whole is undergoing acceleration as a result of a yet unknown form of dark energy . ...

... You need to decide which standard of rest you would like to use. ... You also need to decide how you want this correction to be applied - to the center of each correlator board or to the four boards as a whole (thereby preserving the topocentric frequency offset between the boards). Typically, this choice depends on whether each board is centered on a known spectral line, or if you are doing a search in velocity space for an object. ...

... Your main research interests concern redshift surveys. ... Over half the history of the universe has occurred since redshift one. If we observe out to redshift 1.5, that is around 70% of the whole history of the universe! ... Little evolution in the numbers of elliptical galaxies is seen out to redshift one. ... Galaxy clusters have also changed: at redshifts around one, clusters seem to contain more spiral galaxies, fewer S0s and the same number of giant elliptical galaxies as we see today. ...

Existing models of the zodiacal cloud have always adopted an equilibrum assumption, in which the input from comet and asteroid disintegration balances the output from collisional grinding between the dust particles and their removal by the Poynting-Robertson effect. ...
... Abstract: We present an extensive study of the radiative transfer in dusty galaxies based on Monte Carlo simulations. ... We have explored the dependence of A_l on a conspicuous set of quantities (Hubble type, inclination, dust optical thickness, dust distribution and extinction properties) for a large wavelength interval, ranging from 1250A to the K band, thus finally providing a comprehensive atlas of dust extinction in galaxies, which is electronically available. ...

... Many extragalactic objects for which radial velocities are desired display strong emission lines. ... EMSAO, a companion to the cross-correlation task XCSAO (Kurtz et al. 1992), was written to find emission lines automatically, compute redshifts for each identified line, and combine them into a single radial velocity. ... Figure: This EMSAO Summary page shows line centers and fit information for a night sky spectrum. ... To test EMSAO adequately, a lot of emission line spectra were needed. ...
... A tussle in the distant Universe. This Hubble Space Telescope image shows evidence for a merger between a quasar and a companion galaxy. The quasar is the bright object just beneath the image center, and the wisps of material around it are remains of a galaxy disrupted by the interaction between it and the quasar. ...

... Our Galaxy . Milky Way . ... Universe . ... Space Flight . ... Other galaxies are not moving away because they are recoiling in disgust from the Milky Way, but appear to be receding because the Universe is expanding. ... Observers in any galaxy will see every other galaxy as redshifted, so there is nothing special about the Milky Way. ... If the Universe is expanding today, that implies that in the past the galaxies would have been closer together and the Universe was much smaller than it is now. ...

... ARC 3.5m | NICFPS . ... Taking Exposures . ... As with other IR detectors, it has the capability to be read out non-destructively, allowing for multiple readouts per exposure. In NICFPS, the number of times the detector is read out for each exposure is determined by the Fowler Sampling (FS or NFS, Number of Fowler Samples) setting. ... The NFS=0 mode is somewhat unusual for an IR detector; in this mode, the array is reset, the specified exposure time elapses, and then the detector is read out. ...
