      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 effects of adult aging and induced positive and negative mood on planning 

      Phillips, L.; Smith, L.; Gilhooly, K. (2002)
      Changes in executive functions have been found in older adults and also in young adults experiencing positive or negative mood states. The current study investigated the hypothesis that older adults would show greater ...

    • Factors influencing prescribing decisions in the treatment of depression : a social judgement theory approach 

      Smith, L.; Gilhooly, K.; Walker, A.E. (2003)

    • A large spectroscopic sample of L and T dwarfs from UKIDSS LAS : peculiar objects, binaries, and space density 

      Marocco, F.; Jones, H.R.A.; Day-Jones, A. C.; Pinfield, D.J.; Lucas, P.W.; Burningham, B.; Zhang, Z. H.; Smart, R.L.; Gomes, J. I.; Smith, L. (2015-06-01)
      We present the spectroscopic analysis of a large sample of late-M, L, and T dwarfs from UKIDSS. Using the YJHK photometry from ULAS and the red-optical photometry from SDSS we selected a sample of 262 brown dwarf candidates ...

      Dysfunction of the ubiquitin-proteasome system occurs in the substantia nigra (SN) in Parkinson's disease (PD). However, it is unknown whether this is a primary cause or a secondary consequence of other components of the ...

    • Multiwavelength detection of an ongoing FUOr-type outburst on a low-mass YSO 

      Guo, Zhen; Lucas, P. W.; Kurtev, R. G.; Borissova, J.; Elbakyan, V.; Morris, C.; Bayo, A.; Smith, L.; Garatti, A. Caratti o; Peña, C. Contreras; Minniti, D.; Jose, J.; Ashraf, M.; Alonso-García, J; Miller, N.; Muthu, H. D. S. (2024-03-01)
      During the pre-main-sequence evolution, Young Stellar Objects (YSOs) assemble most of their mass during the episodic accretion process. The rarely seen FUOr-type events are valuable laboratories to investigate the outbursting ...

    • Photometric variability of massive young stellar objects 

      Teixeira, G. D. C.; Kumar, M. S. N.; Smith, L.; Lucas, P. W.; Morris, C.; Borissova, J.; Monteiro, M. J. P. F. G.; Garatti, A. Caratti o; Peña, C. Contreras; Froebrich, Dirk; Gameiro, J. F. (2018-11-05)
      The Vista Variables in the Via Lactea (VVV) survey has allowed for an unprecedented number of multi-epoch observations of the southern Galactic plane. In a recent paper, 13 massive young stellar objects (MYSOs) have already ...
