... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

... 8, ``Celestial Mechanics'', 2002 Estimation of masses of some minor planets from observations of perturbed bodies O. M. Kochetova Institute of Applied Astronomy, St. Petersburg, Russia The most straightforward method of mass determination of minor planets is the dynamical one which uses the gravitational perturbations produced by minor planet in the motion of other bodies. ... The values of the masses of minor planets (15), (29) and (65) appear to be rather close in both papers. ...

... Exposure Time Calculator (ETC) . Survey processing . ... VISTA is a 4-m class wide field survey telescope for the southern hemisphere, equipped with a near infrared camera (1.65 degree diameter field of view at VISTA's nominal pixel size) containing 67 million pixels of mean size 0.34 arcsec and available broad band filters at Z,Y,J,H,K s and a narrow band filter at 1.18 micron. A wide field visible camera, if constructed, could also be used on VISTA. ... Tile . ... ESO VISTA Public Surveys . ...

... It should be recalled that most (99.99 percent) of the energy is dissipated by single radiopulsars in the form of relativistic particles and low-frequency electromagnetic waves which are not observable. ... This gives rise to an interesting analog of the classical reflection or heating effect (Lipunov, 1980[ 97 ]; Lipunov and Prokhorov, 1984[ 110 ]; Harding, 1991[ 64 ]; Lipunov and Nazin, 1994[ 119 ]). ... For close binary systems, -0.3 and the transformation coefficient may be several percent. ...

... Giant radio galaxies (GRGs) form the extreme end of the linear size distribution of radio galaxies, with sizes in excess of 1 Mpc. ... An example: 3C236 . ... In this paper we present a project on high-frequency radio continuum observations of giant radio galaxies. ... The on-going project of high-frequency observations of giant radio galaxies provides us with data of this intriguing class of objects in a wavelength range which could not be accessed hitherto for sources of this size. ...

... Their large amounts of dust make them ideal objects to study how dust forms in the high-redshift interstellar medium (ISM), and to study the interplay between star formation activity, gas and dust. Up until recent interferometric observations with PdBI and ALMA, the full characterisation of SMGs had been hindered by the large beams of single-dish observations that made it challenging to identify their optical and infrared counterparts. ...

This image shows one of the largest known single objects in the universe, the Lyman-alpha blob LAB-1. This picture is a composite of two different images taken with the FORS instrument on the Very Large Telescope тАФ a wider image showing the surrounding galaxies and a much deeper observation of the blob itself at the center made to detect its polarization. ... This means that the giant "blob" must be powered by galaxies embedded within the cloud. Image credit: ESO/M. Hayes ...
