Detection of the PSR J1741+1351 white dwarf companion with the Gran Telescopio Canarias
We report detection of the binary companion to the millisecond pulsar J1741+1351 with the Gran Telescopio Canarias. The optical source position coincides with...
Detection of variable circular polarization in the SW Sex star V795 Herculis
We report the detection of modulated circular polarization in V795 Her. The degree of polarization increases with wavelength and is modulated with a period of...
Detection of Very-High Energy Gamma-Rays from the BL Lac Object PG 1553+113 with the MAGIC Telescope
The MAGIC telescope has observed very high energy gamma-ray emission from the BL Lac object PG 1553+113 in 2005 and 2006 at an overall significance is 8.8 sigma...
Detection of Vortex Tubes in Solar Granulation from Observations SUNRISE
We investigated a time series of continuum intensity maps and Dopplergrams of granulation in a very quiet solar region at the disk center, recorded with the...
Detections of transit variations in KOI 806 (Tingley+, 2011)
g' and z' photometric time series for the last ~1.6hrs of the transit of KOI 806.2 observed with the Gran Telescopio Canarias at Observatorio del Roque de los...
A detector test bench is described which encompasses among its capabilities a wide, IR-visible spectral range, and a wide range of radiation response. The...
EMIR was shipped to the GTC on May 2016 and had its first light on June 2016. Since the beginning, the EMIR performances have been severely hampered by the many...
Determination of Extragalactic Extinction Laws at UV wavelengths with gravitationally-lensed QSOs
The study of extragalactic extinction laws is of paramount importance as it plays a key role in galaxy evolution, as well as for the determination of the...
