Simultaneous INTEGRAL, RXTE, Swift and FT South observations of the transition of GX 339-4
As GX 339-4 has started to leave the Low/Hard State (ATel #2545), we triggered the 2nd part of our INTEGRAL campaign on GX 339-4 in the declining phase of the...
Simultaneous Multi-wavelength Observations of Mrk 421 During the 2006 Outburst
We report on the results of a coordinated observation of Mrk 421 during outburst using data from XMM-Newton and ground-based TeV data from two Imaging Air...
Simultaneous Multi-wavelength Observations of TeV Blazars
The TeV blazars Markarian 421 and Markarian 501 are excellent laboratories for studying the physical processes within the jets of active galactic nuclei due to...
Simultaneous observations in four optical bands of near-Earth asteroids using TCS/MuSCAT2 instrument
The near-Earth asteroids (NEAs) represent excellent scientific opportunities to study the dynamical and physical properties of small bodies of the Solar System...
Simultaneous Optical And X-ray Flickering Observations Of GX 339-4: Correlations On Sub-second Timescales
We present a rapid timing analysis of VLT (optical) and RXTE data of the Galactic black hole GX 339-4 in the low/hard state in June 2007, soon after emerging...
Simultaneous Visible and IR spectropolarimetry of the quiet Sun
This work presents the first quiet Sun spectropolarimetric observations carried out in the visible and the infrared (IR) simultaneously. The Fe I lines at 6301...
