1. Phil Plait's Bad Astronomy: Bitesize Astronomy
... 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. ...

3. Weak Lensing Distorts the Universe
... Intervening dark matter , which is normally invisible, might show its presence by distorting images originating in the distant universe , much the way an old window distorts images originating on the other side. By noting the degree to which background galaxies appear unusually flat and unusually similar to neighbors, the dark matter distribution producing these weak gravitational lensing distortions can be estimated. ... Publications with keywords: universe - gravitational lens - dark matter . ...

7. Charge Transfer Efficiency
... The WFPC2 CCDs have a small b ut significant charge transfer efficiency (CTE) problem which causes some signal to be lost when charge is transferred down the chip during readout. This has the effect of making objects at higher row numbers (more charge transfers) appear fainter than they would if they were at low row numbers. The effect depends on the temperature of the CCDs. ... It is also possible that proportional losses for fainter stars, at least with no background, may be larger. ...

8. What is HISA?
... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ... HISA Main ...

9. Long description of example illustrating the separated borders model
This diagram shows the effect of the 'separate' value of the 'border-collapse' property. The diagram shows a three column, two row table whose cells are subject to the separated borders model. The cells themselves have a grey background color and an 'inset' border style, which makes them appear to sink into the page. ... The table itself has a 10pt 'outset' border that gives one the impression the table is rising out of the page. ...

11. X--ray Quiet PMS Candidates
... There are several explanations for these X--ray quiet PMS stars. To examine the explanations, it is proper to divide the PMS stars into three groups: those bluer than R - I = 0.7, those redder than the X--ray sources (R - I > 1.25) and those with colors similar to the X--ray sources. ... A total of 26 of the non--X--ray detected PMS candidates had spectra taken. ... Between V=14 and V=16, I find 25 stars which are X--ray sources and estimate 19 non--X--ray PMS stars. ...

In 2001, Westerbork observations of the disturbed galaxy named VV-29 (alias Arp-188, UGC-10214) showed that there is second smaller galaxy (named VV-29c) that appears behind the western side of the main body of the distorted galaxy. ...
