Very-high-frequency oscillations in the main peak of a magnetar giant flare
Magnetars are strongly magnetized, isolated neutron stars1–3 with magnetic fields up to around 1015 gauss, luminosities of approximately 1031–1036 ergs per second and rotation periods of about 0.3–12.0 s. Very en...

The Large Observatory for X-ray Timing (LOFT)
High-time-resolution X-ray observations of compact objects provide direct access to strong-field gravity, to the equation of state of ultradense matter and to black hole masses and spins. A 10 m2-class instrument...

Compact sources as the origin of the soft γ-ray emission of the Milky Way
The Milky Way is known to be an abundant source of γ-ray photons1, now determined to be mainly diffuse in nature and resulting from interstellar processes2. In the soft γ-ray domain, point sources are expected to...

Localization of the solar flare SF900610 in X-rays with the WATCH instrument of the GRANAT observatory
During the solar flare of June 10, 1990, the WATCH instrument of the GRANAT space observatory obtained 110 localizations of the X-ray source in the X-ray range 8–20 keV. Its coordinates were measured with an a...

Observation of quasi-periodic pulsations in the solar flare SF 900610
A quasi-periodic component was found at the maximum of the X-ray light curve for the June 10, 1990 solar flare detected by the Granat observatory. The pulsation period was 143.2±0.8 s. The intensity of the pul...

Deka-keV X-ray emission associated with the onset of radio noise storms
Radio noise storms show that suprathermal electrons (a few tens of keV) are present in the vicinity of active regions during several hours or even a few days. Where and how these electrons are energized is not...
