    • Classification of Chandra X-Ray Sources in Cygnus OB2 

      Kashyap, Vinay L.; Guarcello, Mario G.; Wright, Nicholas J.; Drake, Jeremy J.; Flaccomio, Ettore; Aldcroft, Tom L.; Albacete Colombo, Juan F.; Briggs, Kevin; Damiani, Francesco; Drew, Janet E.; Martin, Eduardo L.; Micela, Giusi; Naylor, Tim; Sciortino, Salvatore (2023-11-01)
      We have devised a predominantly Naive Bayes−based method to classify X-ray sources detected by Chandra in the Cygnus OB2 association into members, foreground objects, and background objects. We employ a variety of X-ray, ...

    • First Confirmed Detection of a Bipolar Molecular Outflow from a Young Brown Dwarf 

      Phan-Bao, Ngoc; Riaz, Basmah; Lee, Chin-Fei; Tang, Ya-Wen; Ho, Paul T. P.; Martin, Eduardo L.; Lim, Jeremy; Ohashi, Nagayoshi; Shang, Hsien (2008-12-20)

    • A Tale of Three Cities : OmegaCAM discovers multiple sequences in the color-magnitude diagram of the Orion Nebula Cluster 

      Beccari, G.; Petr-Gotzens, M.G.; Boffin, H.M.J.; Romaniello, M.; Fedele, D.; Carraro, G.; Marchi, G. De; de Wit, W.J.; Drew, J. E.; Kalari, V. M.; Manara, Carlo Felice; Martin, Eduardo L.; Mieske, S.; Panagia, N.; Testi, L.; Vink, Jorick S.; Walsh, J. R.; Wright, N. J. (2017-07-27)
      As part of the Accretion Discs in H$\alpha$ with OmegaCAM (ADHOC) survey, we imaged in r, i and H-alpha a region of 12x8 square degrees around the Orion Nebula Cluster. Thanks to the high-quality photometry obtained, we ...
