    • 76 T dwarfs from the UKIDSS LAS: benchmarks, kinematics and an updated space density 
      Burningham, Ben; Cardoso, C. V.; Smith, L.; Leggett, S. K.; Smart, R. L.; Mann, A. W.; Dhital, S.; Lucas, P. W.; Tinney, C. G.; Pinfield, D. J.; Zhang, Z.; Morley, C.; Saumon, D.; Aller, K.; Littlefair, S. P.; Homeier, D.; Lodieu, N.; Deacon, N.; Marley, M. S.; Spaandonk, L. van; Baker, D.; Allard, F.; Andrei, A. H.; Canty, J.; Clarke, J.; Day-Jones, A. C.; Dupuy, T.; Fortney, J. J.; Gomes, J.; Ishii, M.; Jones, H. R. A.; Liu, M.; Magazzú, A.; Marocco, F.; Murray, D. N.; Rojas-Ayala, B.; Tamura, M. (Oxford University Press on behalf of the Royal Astronomical Society, 2013-07)
      We report the discovery of 76 new T dwarfs from the UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS). Near-infrared broad- and narrow-band photometry and spectroscopy are presented for the new objects, along ...
    • A deep WISE search for very late type objects and the discovery of two halo/thick-disc T dwarfs: WISE ... 
      Pinfield, D. J.; Gomes, J.; Day Jones, A. C.; Leggett, S. K.; Gromadzki, M.; Burningham, B.; Ruiz González, María Teresa; Kurtev, R.; Cattermole, T.; Cardoso, C.; Lodieu, N.; Faherty, J.; Littlefair, S.; Smart, R.; Irwin, M.; Clarke, J. R. A.; Smith, L.; Lucas, P. W.; Gálvez Ortiz, M. C.; Jenkins, James Stewart; Jones, H. R. A.; Rebolo, L.; Béjar, V. J. S.; Gauza, B. (Oxford University Press, 2014)
      A method is defined for identifying late-T and Y dwarfs in WISE down to low values of signalto- noise. This requires a WISE detection only in theW2-band and uses the statistical properties of the WISE multiframe measurements ...
    • Discovery of a T dwarf plus white dwarf binary system 
      Day-Jones, A. C.; Pinfield, D. J.; Ruiz González, María Teresa; Beaumont, H.; Burningham, B.; Gallardo, J.; Gianninas, A.; Bergeron, P.; Napiwotzki, R.; Jenkins, James Stewart; Zhang, Z. H.; Murray, D. N.; Catalán, S.; Gomes, J. (WILEY-BLACKWELL, 2011-01)
      We present the discovery of the first T dwarf + white dwarf binary system LSPM 1459+0857 AB, confirmed through common proper motion and spectroscopy. The white dwarf is a high proper motion object from the LSPM catalogue ...
    • Spectroscopic aperture biases in inside-out evolving early-type galaxies from CALIFA 
      Gomes, J.; Papaderos, P.; Vilchez, J.; Kehrig, C.; Iglesias Paramo, J.; Breda, I.; Lehnert, M.; Sánchez, S.; Ziegler, B.; dos Reis, S.; Bland Hawthorn, J.; Galbany, Lluis; Bomans, D.; Rosales Ortega, F.; Walcher, C.; Garcia Benito, R.; Marquez, I.; Olmo, A. del; Molla, M.; Marino, R.; Catalán Torrecilla, C.; González Delgado, R.; López Sánchez, Ángel R. (EDP SCIENCES, 2016)
      Integral field spectroscopy (IFS) studies based on CALIFA survey data have recently revealed ongoing low-level star formation (SF) in the periphery of a small fraction (similar to 10%) of local early-type galaxies (ETGs), ...
    • Spiral-like star-forming patterns in CALIFA early-type galaxies 
      Gomes, J.; Papaderos, P.; Vilchez, J.; Kehrig, C.; Iglesias Paramo, J.; Breda, I.; Lehnert, M.; Sánchez, S.; Ziegler, B.; Dos Reis, S.; Bland Hawthorn, J.; Galbany, Lluis; Bomans, D.; Rosales Ortega, F.; Walcher, C.; García Benito, R.; Marquez, I.; Olmo, A. del; Molla, M.; Marino, R.; Catalan Torrecilla, C.; González Delgado, R. M.; López Sánchez, Ángel R. (EDP SCIENCES, 2016)
      Based on a combined analysis of SDSS imaging and CALIFA integral field spectroscopy data, we report on the detection of faint (24 < mu(r) mag/square" < 26) star-forming spiral-arm-like features in the periphery of three ...
    • The sub-stellar birth rate from UKIDSS 
      Day Jones, A. C.; Marocco, F.; Pinfield, D. J.; Zhang, Z. H.; Burningham, B.; Deacon, N.; Ruiz González, María Teresa; Gallardo, J.; Jones, H. R. A.; Lucas, P. W.; Jenkins, James Stewart; Gomes, J.; Folkes, S. L.; Clarke, J. R. A. (Oxford University Press on behalf of the Royal Astronomical Society, 2013)
      We present a new sample of mid-L to mid-T dwarfs with effective temperatures of 1100– 1700 K selected from the UKIDSS Large Area Survey (LAS) and confirmed with infrared spectra from X-shooter/Very Large Telescope . This ...
