We report on our ~4 ks Chandra ACIS observation of XMMU J004243.6+412519, an X-ray transient first reported by Henze et al. (2012a, Atel #3890) after its appearance in their 2012-01-15 XMM-Newton observation. Its luminosity exceeded 1E+39 during a follow-up XMM-Newton observation, and Henze et al. (2012b, Atel #3921) classified it as the second

We report the identification of a candidate optical counterpart of IGR J17480-2446 in Hubble Space Telescope (HST) archival observations, taken on 2003 Sept. 17.

NGC 6823 is a young open cluster that lies at a distance of ˜2 kpc in the Vulpecula OB1 association. Previous studies using CCD photometry and spectroscopy have identified a Trapezium system of bright O- and B-type stars at its centre, along with several massive O-, B- and A-type stars in the cluster. We present optical VRI and near-infrared JHK

In this poster, we present the project that will survey all white dwarf stars observed in the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) and the Visible Integral-field Replicable Unit Spectrograph (VIRUS) observations in parallel mode. The final product will be a unique magnitude-limited catalog of as many as 10,000 stars. Since we will
