Galaxy and Cluster Create Four Images of Distant Supernova . ... In this case the masses are a large galaxy and its home galaxy cluster . ... Measuring the locations and time-delays between the supernova images should allow astrophysicists to recover the amount of dark matter in the galaxy and cluster. ... About APOD | ...

... A Gallery of Gravitational Mirages . ... The reason is that distant galaxies act as gravitational lenses , deflecting light that passes nearby. ... Unusual and interesting candidates for gravitational lensing include an edge-on galaxy disk which might be acting as a lens (upper left) and an image nicknamed London Underground (far left) which could well be the distortion of a background galaxy into an optical Einstein ring . ...

... Bad Astronomy . ... Bitesize Astronomy . ... Last week's Snack talked about how black holes can affect the environment around them in such a way as to be very bright . ... It's a common misconception that black holes always have matter swirling into them. ... As this matter gets closer and closer to the black hole it piles up and a large, fairly flat disk forms. This is called the accretion disk , because matter from this disk accretes (that is, falls in) on the black hole. ... 2008 Phil Plait. ...

It is especially hard to explain this process of star birth in some spiral galaxies. ... Targets include both star clusters and galaxies, and star formation rates seen range from the starburst galaxy M82 (the Cigar Galaxy) which is creating about ten new stars in its core alone every year to the much less fecund star producer NGC 2841. ...

... November 9, 1999 . Spiral Galaxies in Collision . ... the Hubble Heritage Team ( AURA / STScI / NASA ) . ... Until then, spiral galaxies NGC 2207 and IC 2163 will slowly pull each other apart, creating tides of matter, sheets of shocked gas , lanes of dark dust , bursts of star formation , and streams of cast-away stars . Astronomers predict that NGC 2207, the larger galaxy on the left, will eventually incorporate IC 2163, the smaller galaxy on the right. ... About APOD > . ...

... 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. ...

... If requested ( runbackground =Y), the task creates a background lightcurve, as well as a background spectrum for the imaging modes (FF, eFF, LW, SW) using background masks. ... The background masks are created by task badpixfind using threshold parameters, appropriate for the detection of real X-ray sources. ... As the GTIs strongly depend on the intended science this screening is not performed and only background masks, the lightcurve, and a GTI file are created by epchain . ...
