    • Assessing the stellar population and the environment of an HII region on the far side of the Galaxy 

      Chené, A. -N.; Benjamin, R. A.; Alegría, S. Ramírez; Borissova, J.; Kurtev, R.; Bidin, C. Moni; Mauro, F.; Lucas, P.; Guo, Z.; Smith, L. C.; Gonzalez-Fernandez, C.; Ivanov, V. D.; Minniti, D.; Anderson, L. D.; Armentrout, W. P.; Gonzalez, D.; Herrero, A.; Ramírez, K. Peña (2021-04-20)
      We have investigated the stellar and interstellar content of the distant star formation region IRAS 17591-2228 (WISE HII region GAL 007.47+0.06). It is associated to a water maser, whose parallax distance is d=20.4^{+2.8} ...

(2019-09-01)
      An improved high-resolution and deep A Ks foreground dust extinction map is presented for the Galactic disc area within 295◦ ≾ l ≾ 350◦, −1.0◦ ≾ b ≾ +1.0◦. At some longitudes the map reaches up to |b| ~ 2.25◦, for a total ...

    • Discovery of a Long-Lived, High Amplitude Dusty Infrared Transient 

      Britt, C. T.; Maccarone, T. J.; Green, J. D.; Jonker, P. G.; Hynes, R. I.; Torres, M. A. P.; Strader, J.; Chomiuk, L.; Salinas, R.; Lucas, P.; Pena, C. Contreras; Kurtev, R.; Heinke, C.; Smith, L.; Wright, N. J.; Johnson, C.; Steeghs, D.; Nelemans, G. (2016-08-11)
      We report the detection of an infrared selected transient which has lasted at least 5 years, first identified by a large mid-infrared and optical outburst from a faint X-ray source detected with the Chandra X-ray Observatory. ...

      The substellar companion HD206893b has recently been discovered by direct imaging of its disc-bearing host star with the SPHERE instrument. We investigate the atypical properties of the companion, which has the reddest ...

    • The UKIRT Hemisphere Survey: definition and J-band Data Release 

      Dye, S.; Lawrence, A.; Fan, X.; Kerr, T.; Varricatt, W.; Furnell, K. E.; Edge, A.; Irwin, M.; Hambly, N.; Lucas, P.; Almaini, O.; Chambers, K.; Hewett, P.; Liu, M.; McGreer, I.; Best, W.; Sutorius, E.; Froebrich, D.; Magnier, E.; Hasinger, G.; Lederer, S.
