Energy Release During Slow Long Duration Flares Observed by RHESSI [PDF]
, 2011 Slow Long Duration Events (SLDEs) are flares characterized by long duration of rising phase. In many such cases impulsive phase is weak with lack of typical short-lasting pulses. Instead of that smooth, long-lasting Hard X-ray (HXR) emission is observed.

Novae and accreting white dwarfs as progenitors of Type Ia supernovae [PDF]
, 2011 I review various phenomena associated with mass-accreting white dwarfs (WDs) in relation to progenitors of type Ia supernovae (SNe Ia). The WD mass can be estimated from light curve analysis in multiwavelength bands based on the optically thick wind ...

Imaging of metastatic lymph nodes by X-ray phase-contrast micro-tomography. [PDF]
PLoS ONE, 2013 Invasive cancer causes a change in density in the affected tissue, which can be visualized by x-ray phase-contrast tomography. However, the diagnostic value of this method has so far not been investigated in detail.

Evidence for Accretion in the High-resolution X-ray Spectrum of the T Tauri Star System Hen 3-600 [PDF]
, 2007 We present high-resolution X-ray spectra of the multiple T Tauri star system Hen 3-600, obtained with the High Energy Transmission Grating Spectrograph on the Chandra X-ray Observatory. Two binary components were detected in the zeroth-order image. Hen 3-
