Despite over 35 years of constant satellite-based measurements of cloud, reliable evidence of a long-hypothesized link between changes in solar activity and Earth’s cloud cover remains elusive. This work examines evidence of a cosmic ray cloud link from a range of sources, including satellite-based cloud measurements and long-term ground-based

A cut-off in the TeV gamma-ray spectrum of the SNR Cassiopeia A
It is widely believed that the bulk of the Galactic cosmic rays is accelerated in supernova remnants (SNRs). However, no observational evidence of the presence of particles of PeV energies in SNRs has yet been found. The young historical SNR Cassiopeia A (Cas A) appears as one of the best candidates to study acceleration processes. Between 2014

A deep look at the nuclear region of UGC 5101 through high angular resolution mid-IR data with GTC/CanariCam
We present an analysis of the nuclear infrared (IR, 1.6-18 μm) emission of the ultraluminous IR galaxy UGC 5101 to derive the properties of its active galactic nucleus (AGN) and its obscuring material. We use new mid-IR high angular resolution (0.3-0.5 arcsec) imaging using the Si-2 filter (λC = 8.7 μm) and 7.5-13 μm spectroscopy taken with

A DIACHRONIC ANALYSIS OF ORIENTATION OF SACRED PRECINCTS ACROSS JORDAN
Located in the southern part of the Levant, the territory of present day Jordan functioned as a cultural crossroad since times immemorial. The state of preservation of the different remains and the quantity of the different stages makes Jordan a perfect area to perform a study on the evolution along time of the orientation customs. During our field

A Different Approach to Calculate the Far-Side Seismic Migration
Seismic images of magnetic activity on the far surface of the Sun are calculated using the seismic holography technique. The method is based on the comparison of waves going in and out of a particular point (focus) in the Sun and requires computation of the Green's function representing the disturbance measured on the front side (pupil) from a unit

A Direct Imaging Search for Substellar-Mass Companions around Solar-Type Stars in the Upper-Sco OB Association
We present first results from our search for brown dwarf and giant planet companions around G and K type stars in the Upper Sco OB association. Our survey is designed to detect companions as faint as I=20 about 2 arcsec from the star. This sensitivity corresponds to 10MJ at 300 AU according to current evolutionary models. The host stars were
