Next: Extinction properties (transmitted radiation) . ... The notes in their current form concern only 2 but main for astronimy aspects of the optical properties of cosmic dust - the ability to extinct and polarize transmitted radiation. The corresponding obervational effects the extinction and polarization (not due to scattering) plaied and plays till now the primary role in astrophysical effects of cosmic dust considered in the literature. ... Extinction properties (transmitted radiation) . ...

... Your main research interests concern dust. ... One of your main pleasures in life is going to conferences, and asking the question `have you considered dust obscuration?' after every talk by an optical astronomer, and watching their embarrassed evasions. ... Just look at any starburst galaxy: they are the most luminous objects in the local universe, but they are so dusty that the optical astronomers never even noticed them until the infra-red astronomers pointed them out! ...

Next: Population Synthesis of X-ray Up: Cosmic Rays and Evolution Previous: Supernova Explosions . Immediately after the discovery of pulsars, especially of the Crab pulsar,   it became clear that rapidly rotating NS are copious sources of relativistic particles. ... Figure 37: Evolution of magnetorotational energy of NS in elliptical and spiral galaxies. ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . TELESCOPES . ... Each dome contains a telescope with many mirror segments, which combine to give a light collecting area of 10 meters (about 10 yards) across. These are currently the largest light-collecting telescopes in the world, although the European Southern Observatory is building a series of four giant telescopes in Chile which will have a larger collecting area when their light is combined. ...

... Comet Animation . ... Comet structures are diverse and very dynamic, but they all develop a surrounding cloud of diffuse material, called a coma, that usually grows in size and brightness as the comet approaches the Sun. ... As comets approach the Sun they develop enormous tails of luminous material that extend for millions of kilometers from the head, away from the Sun. ... The evaporated molecules boil off and carry small solid particles with them, forming the comet's coma of gas and dust. ...

http://hubblesite.org/newscenter/archive/releases/1996/22/text/ Probing the mysterious heart of the Crab Nebula, the tattered remains of a stellar cataclysm witnessed more than 900 years ago, astronomers using NASA's Hubble Space Telescope have found that the Crab is even more dynamic than previously understood, based on a cosmic "movie" assembled from a series of Hubble observations. ... Because of this flickering, the neutron star is also called a "pulsar." ...

Seven months ago, on Mar 19, 2008, at 09:12 Moscow time, a new star appeared on the sky. The Sun had already risen over the Russia, but people of the Western hemisphere might be able to see by their eyes a faint starlet near one of Bootes constellation stars. This starlet appeared and faded by an order of magnitude in a minute. Astronomers named it GRB080319B or, informally, the Naked-Eye Burst, as it was twice as bright as human eye can see a star. ...

... Galaxies 99 Cosmic background with model of cloudy interstellar medium Yu. ... Figure 1: Averaged spectrum of the cosmic background I f in frequency range 0.25 200 MHz for the Galactic poles. ... First interpretation of the cosmic noise background spectrum at broad band frequency range 0.25 200 MHz with a model of the cloudy interstellar medium ISM is presented here. ... Synthesized background spectra I f for regions of the Galactic poles at the frequency range 0.25 200 MHz is presented in Fig. ...

The angular power spectrum of the anisotropy of the CMB contains information about the formation of the Universe and its current contents. ... The image above shows an all-sky map with only ell=2 power on the left, and another map with only ell=16 power on the right. ... The current status of microwave background anisotropy measurements in my compilation from the literature has 95 data points from 25 experiments. These are all plotted in the figure below: . ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... A faint, dusty rose of the northern sky, emission nebula IC 410 lies about 12,000 light-years away in the constellation Auriga. The cloud of glowing hydrogen gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. ... These "tadpoles" (seen just below center) are regions of denser, cooler gas, and more slowly resist the erosive radiation from the hot stars. ...

... Previous: A Posteriori Guidance for Astronomical Images . ... We present an original algorithm for the recognition of anomalous events in a CCD frame (i.e., cosmic hits, bad pixels etc.) The algorithm is able to distinguish between these events and real features by comparing the standard deviation and the kurtosis of a synthetic PSF, whose width is given by the user, and the corresponding values in a running window, whose size is chosen by the user, in the actual frame. ...
