Descripción
On April 10th, it was discovered (ATel #2548) using INTEGRAL that the neutron-star X-ray binary Swift J1749.4-2807 (Wijnands et al. 2009, MNRAS, 393, 126) was again in outburst. Using follow-up Swift and INTEGRAL observations the source activity was confirmed (ATel #2548 and #2561). On April 14th, 2010 (20:58:00 UT), RXTE performed a pointed observation of Swift J1749.4-2807. The observation lasted for about 1.6 ksec, at a background-corrected count rate of ~30 cts/sec/PCU (2 PCUs were active during this observation) in the 2-16 keV range.

    Design and manufacture of athermalized optomechanical mounts for GRANCAIN, the infrared imaging instrument for GTC's adaptive optics
    GRANCAIN (GRAN CAmara INfrarroja) is a first-light imaging instrument in the infrared J, H and K bands that will be integrated into the adaptive optics focus of the Gran Telescopio de Canarias. The purpose of the instrument is to capture SWIR diffraction-limited images for a field of view of 22x22 arcsec. The instrument boasts a telecentric optical

    Measuring Rotation Periods and Stellar Oscillations in Red Giants with TESS Data
    TESS is a powerful engine for studying stellar variability. However, it has been challenging to adopt methods used for other space missions, such as Kepler, to infer rotation periods and solar-like oscillation frequencies in TESS data. The availability of multiple sectors of data for most targets, improved stability, and the release of new
