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. ...

2. Near-infrared millihertz variability of the wisps and jet in the crab pulsar
We present a time-lapse sequence of 20 near-infrared ( J and K band) snapshots of the central 20 20 of the Crab pulsar wind nebula, taken at subarcsecond resolution with the Hokupa`a/QUIRC adaptive optics camera on the Gemini North Telescope and sampled at intervals of 10 minutes and 24 hr. It is observed that the equatorial wisps and polar knots in the termination shock of the pulsar wind appear to fluctuate in brightness on kilosecond timescales. ...

5. Relative pathnames
. You can define a file or directory by its location in relation to your current directory . The pathname is given as / (slash) separated list of the directories on the route to the file (or directory) from your current directory. A .. (dot dot) is used to represent the directory immediately above the current directory. In all shells except the Bourne shell, the ~ (tilde) character can be used as shorthand for the full pathname to your home directory. Examples . Did You Know? .

9. Continuous wavelet transforms
... Therefore, we see that some spectral resolution is achieved by selection of the wavelet size, and some temporal resolution follows from the location of the wavelet relative to the signal (Fig. ... Figure 6: Contour line representation of the wavelet transform for a near-continuum of durations. We can identify the individual peaks and troughs of the cosine wave as well as their frequency: this compromise between the temporal domain and the spectral domain is the hallmark of wavelet transforms. ...

13. Wavelength Calibration at Moderately High Resolution
... The calibration of astrophysical spectra in wavelength based on calibration lamp data suffers from different kinds of uncertainties. Besides inaccuracies in the observational phase, common data reduction practice adds ``pixelation'' errors, due to the fact that the centering method does not use the correct PSF. These model mismatch errors depend, for a given feature, on the sub-pixel location of the line center (David & Verschueren, private communication). ...
