We fit the X-ray spectra with a suite of phenomenological models in order to characterize the data. Note: Depending on your screen size, you might only see the icons for WordArt Styles. Go to Shape Format or Drawing Tools Format, select Text Effects > Transform and pick the look you want. Additional setting allow you to control the position of the text in relation to the vector guide. The X-ray low-state spectra of the 20 XMM-Newton observations display significant spectral variability. Replace the WordArt placeholder text with your own text. Text on a Curve The Text on a Curve feature of the Text tool allows you to specify a vector shape or line that can be used as a guide for the text to flow along. The hardness ratio and count rate are correlated in the low-flux state, but no correlation is seen in the high state. We find no significant correlation or lag between the UV and X-ray variability however, we do find distinct trends in the behavior of the hardness ratio variability. Long-term Swift monitoring allows us to examine correlations between the UV, X-rays, and X-ray hardness ratios. Adjustable layout guides are used for precise object placement.
Add as many layers as you wish and choose to make them invisible or unprintable.

In the UV, it turns out to be one of the most variable among NLS1s. The Text to Curve option lets you transform fonts into vector lines a common requirement when submitting documents to a print shop for professional printing. Mkn 335 has shown strong X-ray variability even on timescales of hours. 2 This paper aims, informed by the literature from the fields of applied risk communication. This is one of the longest simultaneous UV/X-ray light curves so far obtained for an AGN. The paper presented here expands on the same authors’ communications guidance for the task force report. Swift has continuously monitored Mkn 335 since 2007 May typically on a monthly basis. Here we report on the continuation of our ongoing monitoring campaign with Swift and the examination of the low-state X-ray spectra based on a 200 ks triggered observation with XMM-Newton in 2009 June. It has become one of the prototype active galactic nuclei (AGNs) in deep minimum X-ray states. Abstract The narrow-line Seyfert 1 galaxy (NLS1) Mkn 335 is remarkable because it has repeatedly shown deep, long X-ray low states that show pronounced spectral structure.
