Orientation studies have recently received considerable attention in the archaeological domain as a source of information that may shed light on a number of anthropological issues such as beliefs systems or landscape and territory apprehension by past cultures. This is especially important in those cultural contexts, such as the ‘megalithic’

We present Gran Telescopio CANARIAS CanariCam 8.7 μm imaging and 7.5-13 μm spectroscopy of six local systems known to host an active galactic nucleus (AGN) and have nuclear star formation. Our main goal is to investigate whether the molecules responsible for the 11.3 μm polycyclic aromatic hydrocarbon (PAH) feature are destroyed in the close

We discuss the method, and potential systematic effects therein, used for measuring the mass of stellar-mass black holes in X-ray binaries. We restrict our discussion to the method that relies on the validity of Kepler's laws; we refer to this method as the dynamical method. We briefly discuss the implications of the mass distribution of stellar

Aims: Amongst more than fifty blazars detected in very high energy (VHE, E> 100 GeV) γ rays, only three belong to the subclass of flat spectrum radio quasars (FSRQs). The detection of FSRQs in the VHE range is challenging, mainly because of their soft spectra in the GeV-TeV regime. MAGIC observed PKS 1510-089 (z = 0.36) starting 2012 February 3

The dissolution of fullerene C60 in oleum (fuming sulphuric acid 20 % free SO3) was followed simultaneously with ESR (Electron Spin Resonance) and NIR (Near Infrared Spectroscopy). It is shown that the intensity of the ESR signal associated to the formation of C60 radical cation (C60+•) follows the same kinetics as the NIR absoption band at about

We describe a search for submillimeter emission in the vicinity of one of the most distant, luminous galaxies known, HerMES FLS3, at z = 6.34, exploiting it as a signpost to a potentially biased region of the early universe, as might be expected in hierarchical structure formation models. Imaging to the confusion limit with the innovative, wide
