Power-law tails in probability density functions of molecular cloud column density [PDF]

, 2015
Power-law tails are often seen in probability density functions (PDFs) of molecular cloud column densities, and have been attributed to the effect of gravity. We show that extinction PDFs of a sample of five molecular clouds obtained at a few tenths of a

Power density spectrum of NGC 5548 and the nature of its variability [PDF]

, 1998
We derive power density spectra in the optical and X-ray band in the timescale range from several years down to $\sim $ a day. We suggest that the optical power density spectrum consists of two separate components: long timescale variations and short ...

Power loss and electromagnetic energy density in a dispersive metamaterial medium

, 2009
The power loss and electromagnetic energy density of a metamaterial consisting of arrays of wires and split-ring resonators (SRRs) are investigated. We show that a field energy density formula can be derived consistently from both the electrodynamic (ED)
