Observations of binary stars containing an accreting black hole or neutron star often show x-ray emission extending to high energies (>10 kilo--electron volts), which is ascribed accretion disk corona energetic particles akin those seen in the solar corona. Despite their ubiquity, physical conditions coronae remain poorly constrained. Using simultaneous infrared, optical, x-ray, and radio observations Galactic system V404 Cygni, showing a rapid synchrotron cooling event its 2015 outburst, we...
The Mid-resolution InfRAreD Astronomical Spectrograph (MIRADAS, a near-infrared multi-object echelle spectrograph operating at spectral resolution R=20,000 over the 1-2.5μm bandpass) was selected in 2010 by Gran Telescopio Canarias (GTC) partnership as next-generation for world's largest optical/infrared telescope, and is being developed an international consortium. MIRADAS consortium includes University of Florida, Universidad de Barcelona, Complutense Madrid, Instituto Astrofísica...

The Canarias InfraRed Camera Experiment (CIRCE) is a near-infrared (1–2.5[Formula: see text][Formula: text]m) imager, polarimeter and low-resolution spectrograph operating as visitor instrument for the Gran Telescopio (GTC) 10.4-m telescope. It was designed built largely by graduate students postdocs, with help from University of Florida (UF) astronomy engineering group, funded UF US National Science Foundation. CIRCE intended to fill gap in capabilities prior arrival Especrografo...
We describe the design, development, and laboratory test results of cryogenic probe arms feeding deployable integral field units (IFUs) for Mid-resolution InfRAreD Astronomical Spectrograph (MIRADAS) - a near-infrared multi-object echelle spectrograph 10.4-meter Gran Telescopio Canarias. MIRADAS selects targets using 20 positionable pickoff mirror optics on arms, each 3.7x1.2-arcsec view to units, while maintaining excellent diffraction-limited image quality. The are based concept developed...
