Upper limits on gravitational wave bursts in LIGO's second science run
We perform a search for gravitational wave bursts using data from the second science run of the LIGO detectors, using a method based on a wavelet time-frequency...
Upper Limits on the VHE Gamma-Ray Emission from the Willman 1 Satellite Galaxy with the Magic Telescope
We present the result of the observation of the ultrafaint dwarf galaxy Willman 1 performed with the 17 m MAGIC telescope during 15.5 hr between March and May...
Upper Limits to the Magnetic Field in Central Stars of Planetary Nebulae
More than about 20 central stars of planetary nebulae (CSPNs) have been observed spectropolarimetrically, yet no clear, unambiguous signal of the presence of a...
Uranian ring orbits from earth-based and Voyager occultation observations
The authors have combined an enhanced Earth-based occultation data set and Voyager occultation observations to determine a new solution for the ring orbital...
Urban Planning in the First Unfortified Spanish Colonial Town: The Orientation of the Historic Churches of San Cristóbal de La Laguna
The city of San Cristóbal de La Laguna in the Canary Island of Tenerife (Spain) is of exceptional value as the first unfortified colonial city to follow regular...
USco1621 B and USco1556 B: Two wide companions at the deuterium-burning mass limit in Upper Scorpius
Aims: Our objective is to identify analogues of gas giant planets, but located as companions at wide separations of very young stars. The main purpose is to...
Using a Mesoscale Meteorological Model to Reduce the Effect of Tropospheric Water Vapour from DInSAR Data: A Case Study for the Island of Tenerife, Canary Islands
Measurements of ground displacement through classical Differential Interferometric SAR (DInSAR) and advanced DInSAR techniques have been carried out over the...
Using autoencoders and deep transfer learning to determine the stellar parameters of 286 CARMENES M dwarfs
Context. Deep learning (DL) techniques are a promising approach among the set of methods used in the ever-challenging determination of stellar parameters in M...
