The one-way frontier around a black hole is the event horizon from which nothing can escape.  Close to it, strong effects of gravity and exotic physics are...

We analyze the spectral asymmetry of Stokes V (circularly polarized) profiles of an individual network patch in the quiet Sun observed by Sunrise/IMaX. At a...

We report far-infrared (FIR) imaging of the Seyfert 2 galaxy NGC 3081 in the range 70- 500 μm, obtained with an unprecedented angular resolution, using the...

We have identified for the first time extragalactic rubidium-rich Asymptotic Giant Branch (AGB) stars in low metallicity environments such as the Magellacnic...

The proper characterization of the least massive population of the young Sigma Orionis star cluster is required to understand the form of the cluster mass...

LIRIS, the IR imaging camera and spectrograph built by the IAC, is giving life to new projects. During 2006 advances were made in the search for and analysis of...

Rotation is thought to drive cyclic magnetic activity in the Sun and Sun-like stars. Stellar dynamos, however, are poorly understood owing to the scarcity of...

Aims. We aim to extend our current observational understanding of the integrated planet Earth spectropolarimetry from the optical to the near-infrared...
