We present the RXTE PCA X-ray spectrum of SN 1006. This data exhibits evidence of highenergy non-thermal X-ray emission. An analysis of the RXTE PCA data and data from the ASCA SIS and ROSAT PSPC detectors suggests that the entire broad-band X-ray spectrum of SN 1006 may be t with a single non-equilibrium ionization thermal component and a nonthermal component described by a broken power law wi...

A novel fractionation method, based on both particle size and settling characteristics, was employed to examine metal distributions among five fractions. In-stream and stormwater runoff samples were collected from four land use types: highway, urban, agricultural (storm event and irrigation), and natural. Highway samples contained the highest dissolved concentrations for most metals, and freshw...

One of the seminal events in the history of a tissue is the establishment of the anterior-posterior, dorsal-ventral (D/V) and proximal-distal axes. Axis formation is important for the regional specification of a tissue and allows cells along the different axes to obtain directional and positional information. Within the Drosophila retina, D/V axis formation is essential to ensure that each unit...

The nonthermal X-rays from the SNR 1006 NE rim present characteristic scale lengths that are interpreted in the context of diffusion of a relativistic electron. The adopted theoretical framework is the mathematical diffusion in 3D, 1D and 1D with drift as well as the Monte Carlo random walk in 1D with drift. The asymmetric random walk with diffusion from a plane can explain the scale widths of ...

I discuss the high resolution XMM-Newton Reflection Grating Spectrometer (RGS) spectrum of SN 1006. SN 1006 is one of the best examples of a supernova remnant that is far out of ionization equilibrium. Moreover, optical, UV and X-ray data indicate that it is also out of temperature equilibrium. I discuss the X-ray evidence for this. In addition I discuss the lower resolution RGS spectrum of the...

We present the deepest optical spectrum acquired to date of Balmer-dominated shocks in the NW rim of SN 1006. We detect the broad and narrow components of Hα, Hβ and Hγ and report the first detection of the He I λ 6678 emission line in this supernova remnant. We may have detected, at the 1.5σ level, faint He II λ4686 emission. We measure a full width half maximum of 2290± 80 km s in the broad c...
