Description
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.

    Co-phasing the distributed aperture of a Fizeau interferometer via photonic lanterns and machine learning
    The advantage of large optical telescopes from the ground for high-contrast direct imaging relies on achieving exquisite control of the incident optical wavefront. Since the exoplanet problem almost always has a bright star within a small field of view there are usually ample photons for measuring the atmospheric and telescopedistorted wavefront. A
