Electron Acceleration and Time Variability of High Energy Emission from Blazars

open access: yes, 2000
Blazars are known to emit a broad band emission from radio to gamma-rays with rapid time variations, particularly, in X- and gamma-rays. Synchrotron radiation and inverse Compton scattering are thought to play an important role in emission and the time ...

Secondary sclerosing cholangitis in patients suffering cardiogenic shock

open access: yesESC Heart Failure, Volume 12, Issue 3, Page 2239-2244, June 2025.
Abstract Aims Cardiogenic shock (CS) patients suffer from severe organ hypoperfusion, yet the incidence of secondary sclerosing cholangitis in critically ill patients (SSC‐CIP) in CS is poorly described. Given the limited evidence and severity of this syndrome, we aimed to further investigate SSC‐CIP in the context of CS.

Subaru optical observations of the old pulsar PSR B0950+08

open access: yes, 2002
We report the B band optical observations of an old (17.5 Myr) radiopulsar PSR B0950+08 obtained with the Suprime-Cam at the Subaru telescope. We detected a faint object, B=27.07(16). Within our astrometrical accuracy it coincides with the radio position
