Descripción
We report recent observations of M31 taken with Chandra/ACIS-I on 2009-05-29.1 UT and with Swift/XRT on 2009-06-07.08 UT. In the 4ks Chandra/ACIS-I image, we found a faint transient located at R.A.(J2000)=00h42m26.7s, Decl. (J2000)=+41:13:46.5 with a 90% absolute error of 0.6 arcsec. It is therefore identified as CXOM31 J004226.7+411346. The unbinned energy spectrum can be fit (using C statistic) with an absorbed power-law model (Gamma=2.1, N_H fixed at 7e20 cm^-2).

    The TESS TTV Follow-up Program: Revealing Volatile-Rich Terrestrial Planets Around M Stars
    Models predict that water-rich planets may be common around low-mass stars, but definitive evidence for the existence of water worlds has remained elusive. Recent JWST observations of sub-Neptune sized planets orbiting nearby M dwarfs found atmospheres enriched in CH4, CO2 and H2O, but the enrichment mechanism is debated. To answer this question

    The instrumentation plan of the 10.4m GTC telescope
    The 10.4m Gran Telescopio Canarias (GTC) was designed to be a versatile telescope, able to serve a wide scientific community. To this aim, various focal stations have been equipped, including a Cassegrain, two Nasmyth foci, and four folded-Cassegrain stations. This allows an ambitious instrumentation plan to be developed. We present the latest

    Design and fabrication of fold mirror (M3) system for New Robotic Telescope
    The New Robotic Telescope (NRT) is an autonomous telescope that can operate multiple instruments at the Cassegrain focal station and the straight-through port. The optical beam is directed to the ports by a fold mirror subsystem in the focal station assembly. The fold mirror is elliptical in shape, manufactured by Instituto Nazionale di Astrofisica
