  • Dauphas, N.; Cook, D. L.; Sacarabany, A.; Froehlich, C.; Davis, A. M.; Wadhwa, M.; Pourmand, A.; Rauscher, T.; Gallino, R. (2009-02-01)
  • Barentsen, Geert; Arlt, Rainer; Fröhlich, Hans-Erich (2011-10)
    A method for estimating the true meteor rate lambda from a small number of observed meteors n is derived. We employ Bayesian inference with a Poissonian likelihood function. We discuss the choice of a suitable prior and ...

    Using combinations of H alpha, ultraviolet (UV), and infrared (IR) emission, we estimate the star formation rate (SFR) surface density, Sigma(SFR), at 1 kpc resolution for 30 disk galaxies that are targets of the IRAM ...
  • Beers, T.C.; Rossi, S.; Norris, J.E.; Ryan, Sean G.; Shefler, T. (1999)
    We have recalibrated a method for the estimation of stellar metal abundance, parameterized as [Fe/H], based on medium-resolution (1–2 Å) optical spectra (the majority of which cover the wavelength range 3700–4500 Å). The ...

    We report on the discovery of ETHOS 1 (PN G068.1+11.0), the first spectroscopically confirmed planetary nebula (PN) from a survey of the SuperCOSMOS Science Archive for high-latitude PNe. ETHOS 1 stands out as one of the ...

    We use new mid-infrared (mid-IR) photometry from the Spitzer Space Telescope to study the relations between low-frequency radio luminosity density L-nu 151 (MHz), mid-IR (12 mu m rest frame) luminosity nu L-nu 12 (mu m) ...
  • Barth, A. J.; Sarzi, M.; Rix, H-W.; Ho, L. C.; Filippenko, A.V.; Sargent, W.L.W. (2001-07-01)
    The S0 galaxy NGC 3245 contains a circumnuclear disk of ionized gas and dust with a radius of 1.1" (110 pc), making it an ideal target for dynamical studies with the Hubble Space Telescope (HST). We have obtained spectra ...
  • Smith, Daniel; Jarvis, M.J. (2007)
    In this Letter we report on the discovery of a z = 2.83 Lyman alpha Blob (LAB) found in our wide-field narrow-band survey within the Spitzer First Look Survey region. The blob is extended over at least 95 kpc and has a ...
  • Kraft, R.P.; Hardcastle, M.J.; Sivakoff, G.R.; Jordan, A.; Nulsen, P.E.J.; Birkinshaw, M.; Forman, W.R.; Jones, C.; Worrall, D.M.; Croston, J.H.; Evans, D.A.; Raychaudhury, S.; Murray, S.S.; Brassington, Nicola; Goodger, Joanna; Harris, W.E.; Juett, A.M.; Sarazin, C.L.; Woodley, K.A. (2008)
    We present preliminary results from a deep (600 ks) Chandra observation of the hot interstellar medium of the nearby early-type galaxy Centaurus A. We find a surface brightness discontinuity in the gas ~3.5 kpc from the ...
  • Pipino, A.; Kaviraj, S.; Silk, J.; Bildfell, C.; Babul, A.; Hoekstra, H. (2009-05-01)
    We present a joint analysis of near-ultraviolet (NUV) data from the GALEX (Galaxy Evolution Explorer) mission and (optical) colour profiles for a sample of seven brightest cluster galaxies (BCGs) in the Canadian Cluster ...
  • Hernan-Obispo, M.; Galvez-Ortiz, M.C.; Anglada-Escude, G.; Kane, S.R.; Barnes, J.R.; De Castro, E.; Cornide, M. (2010)
    Context. BD+20 1790 is a young active, metal-rich, late-type K5Ve star. We have undertaken a study of stellar activity and kinematics for this star over the past few years. Previous results show a high level of stellar ...
  • Rauscher, T. (2003-05-19)
    Properties of atomic nuclei important for the prediction of astrophysical reaction rates are reviewed. In the first part, a recent simulation of evolution and nucleosynthesis of stars between 15 and 25 M-circle dot is ...
