  • Sawicki, Marcin, 1969-; Henry, Alaina L.; Martin, Crystal L.; Dressler, Alan; McCarthy, Patrick (American Astronomical SocietyIOP Publishing, 2010-08-10)
    We present NICMOS J[subscript 110] (rest-frame 1200–2100 [Angstrom]) observations of the three z = 5.7 Ly[alpha] emitters discovered in the blind multislit spectroscopic survey by Martin et al. These images confirm the ...

  • Sembolini, Federico; Yepes, Gustavo; Pearce, Frazer R.; Knebe, Alexander; Kay, Scott T.; Power, Chris; Cui, Weiguang; Beck, Alexander M.; Borgani, Stefano; Vecchia, Claudio Dalla; Thacker, Robert John, 1970- (Oxford University Press, 2016-04-21)
    We have simulated the formation of a galaxy cluster in a [lambda] cold dark matter universe using 13 different codes modelling only gravity and non-radiative hydrodynamics (RAMSES, ART, AREPO, HYDRA and nine incarnations ...

  • Cui, Weiguang; Power, Chris; Knebe, Alexander; Kay, Scott T.; Sembolini, Federico; Elahi, Pascal J.; Yepes, Gustavo; Pearce, Frazer; Cunnama, Daniel; Beck, Alexander M.; Thacker, Robert John, 1970- (Oxford University Press, 2016-06-01)
    Building on the initial results of the nIFTy simulated galaxy cluster comparison, we compare and contrast the impact of baryonic physics with a single massive galaxy cluster, run with 11 state-of-the-art codes, spanning ...

  • Arcila-Osejo, Liz; Sawicki, Marcin, 1969- (Royal Astronomical SocietyOxford University Press, 2013-08-19)
    We use an adaptation of the BzK[subscript s] technique to select ∼40 000 z ∼ 2 galaxies (to K[subscript AB] = 24), including ∼5000 passively evolving (PE) objects (to K[subscript AB] = 23), from 2.5 deg[superscript 2] of ...

  • Few, C. G.; Gibson, Brad K.; Courty, S.; Michel-Dansac, L.; Brook, C. B.; Stinson, G. S. (EDP Sciences, 2012-11)
    Aims. We test the validity of comparing simulated field disk galaxies with the empirical properties of systems situated within environments more comparable to loose groups, including the Milky Way’s Local Group. Methods. ...

  • Gibson, Brad K.; Few, C. G.; Courty, S.; Kawata, D.; Calura, F.; Teyssier, R. (Oxford University Press on behalf of the Royal Astronomical Society, 2012-07)
    We present a new chemodynamical code – RAMSES-CH – for use in simulating the self-consistent evolution of chemical and hydrodynamical properties of galaxies within a fully cosmological framework. We build upon the adaptive ...

  • Walker, A. P.; Gibson, Brad K.; Pilkington, K.; Brook, C. B.; Dutta, P.; Stanimirovic, S.; Stinson, G. S.; Bailin, J. (Oxford University Press, 2014-06)
    We present an analysis of the role of feedback in shaping the neutral hydrogen (H I) content of simulated disc galaxies. For our analysis, we have used two realizations of two separate Milky Way-like (∼L★) discs – ...

  • Lemaux, B. C.; Lubin, L. M.; Sawicki, Marcin, 1969-; Martin, C.; Lagattuta, D. J.; Gal, R. R.; Kocevski, D.; Fassnacht, C. D.; Squires, G. K. (American Astronomical SocietyIOP Publishing, 2009-07-20)
    We present results of a spectroscopic search for Ly[alpha] emitters (LAEs) in the Cl1604 supercluster field using the extensive spectroscopic Keck/DEep Imaging Multi-Object Spectrograph database taken as part of the ...

  • Arcila-Osejo, Liz María (Halifax, N.S. : Saint Mary's University, 2011)
    In this work we use the latest results from the four Deep Fields of the Canada France Hawaii Telescope Legacy Survey (CFHTLS) combined with the WIRCam Deep Survey (WIRDs) covering 2 .51 deg [superscript 2] to study the ...

  • Gibson, Brad K.; Calura, F.; Michel-Dansac, L.; Stinson, G. S.; Dotter, A.; Pilkington, K.; House, E. L.; Brook, C. B.; Few, C. G.; Cignoni, M. (Royal Astronomical Society, 2012-12)
    By means of high-resolution cosmological hydrodynamical simulations of Milky Way (MW) like disc galaxies, we conduct an analysis of the associated stellar metallicity distribution functions (MDFs). After undertaking a ...

  • Yuma, Suraphong; Ohta, Kouji; Yabe, Kiyoto; Shimasaku, Kazuhiro; Yoshida, Makiko; Ouchi, Masami; Iwata, Ikuru; Sawicki, Marcin, 1969- (American Astronomical SocietyIOP Publishing, 2010-09-10)
    We present a study of a stellar population of Ly[alpha] emitters (LAEs) at z = 4.86 in the Great Observatories Origins Deep Survey North (GOODS-N) field and its flanking field. The LAEs are selected based on optical ...

  • Gibson, Brad K.; Brook, C. B.; Stinson, G. S.; Kawata, D.; House, E. L.; Miranda, M. S.; Maccio, A. V.; Pilkington, K.; Roskar, R.; Wadsley, J. (Royal Astronomical Society, 2012-10)
    Within a cosmological hydrodynamical simulation, we form a disc galaxy with subcomponents which can be assigned to a thin stellar disc, thick disc and a low-mass stellar halo via a chemical decomposition. The thin- and ...

  • Sorba, Robert; Sawicki, Marcin, 1969- (American Astronomical SocietyIOP Publishing, 2010-10-01)
    We explore the feasibility and limitations of using the 1.6 [micron]m bump as a photometric redshift indicator and selection technique, and use it to study the rest-frame H-band galaxy luminosity and stellar mass functions ...
