    We present Herschel-SPIRE observations at 250–500 μm of the giant elliptical galaxy M 86 and examine the distribution of the resolved cold dust emission and its relation with other galactic tracers. The SPIRE images reveal ...
  • Schulte-Ladbeck, R.; Hopp, U.; Brinks, E.; Kravtsov, A. (2010)
    Dwarf galaxies provide opportunities for drawing inferences about the processes in the early universe by observing our “cosmological backyard”—the Local Group and its vicinity. This special issue of the open-access journal ...
  • Parker, Richard J.; Wright, Nicholas J.; Goodwin, Simon P.; Meyer, Michael R. (2014-02-01)
    We model the dynamical evolution of star-forming regions with a wide range of initial properties. We follow the evolution of the regions' substructure using the Q-parameter, we search for dynamical mass segregation using ...
  • Shelton, D.L.; Hardcastle, M.J.; Croston, J.H. (2011)
    We present a detailed analysis of a new XMM-Newton observation of the Fanaroff-Riley type II (FR II) radio galaxy 3C452 and its environment. We detect X-ray emission from the hot intragroup medium and measure its temperature ...
  • Konar, C.; Jamrozy, M.; Hardcastle, M.J.; Croston, J.H.; Nandi, S.; Saikia, D. J.; Machalski, J. (2011-12)
    Relativistic and magnetized plasma ejected by radio loud AGNs through jets form the diffuse lobes of radio galaxies. The radiating particles (electron/electron-positron) in lobes emit in radio via the synchrotron process ...

  • Rutkowski, Michael J.; Jeong, Hyunjin; Cohen, Seth H.; Kaviraj, S.; Windhorst, Rogier A.; Ryan, Russell E.; Koekemoer, Anton; Yi, Sukyoung K.; Hathi, Nimish P.; Dopita, Michael A. (2014-12-01)
    We present an analysis of the stellar populations of 102 visually selected early-type galaxies (ETGs) with spectroscopic redshifts (0.35 ≲ z ≲ 1.5) from observations in the Early Release Science program with the Wide Field ...
  • Spolaor, Max; Kobayashi, Chiaki; Forbes, Duncan A.; Couch, Warrick J.; Hau, George K. T. (2010-10-11)
    We present the results of a study of stellar population properties at large galactocentric radii of 14 low-mass early-type galaxies in the Fornax and Virgo clusters. We derive radial profiles of age, total metallicity [Z/H] ...

    We present a catalogue of 1768 eclipsing binary stars (EBs) detected in the Large Magellanic Cloud (LMC) by the second generation of the EROS survey (hereinafter EROS-2); 493 of them are new discoveries located in outer ...
  • Viti, S.; Tennyson, J.; Jones, H.R.A.; Schweitzer, A.; Allard, F.; Hauschildt, P. (Astronomical Society of the Pacific, 1998)
    We compare observations from 0.40 to 2.41um of the binary system CM Draconis with synthetic spectra computed using the stellar atmosphere code PHOENIX.
  • Minniti, D.; Saito, R.K.; Alonso-Garcia, J.; Lucas, P.W.; Hempel, M. (2011)
    We use the clump giants of the disk as standard candles calibrated from Hipparcos parallaxes in order to map their distribution with two new near-infrared surveys of the Galactic plane: UKIDSS-GPS and VISTA Variables in ...
  • Pavlenko, Ya.; Jenkins, J.; Jones, H.R.A.; Ivanyuk, O.; Pinfield, D.J. (2012)
    We describe our procedure to determine effective temperatures, rotational velocities, microturbulent velocities, and chemical abundances in the atmospheres of Sun-like stars. We use independent determinations of iron ...
  • Bailey, Jeremy; Ulanowski, Z.; Lucas, P.W.; Hough, J. H.; Hirst, E.; Tamura, M. (2008-05-11)
    In the past, it has generally been assumed that polarization observations made with ground-based telescopes are unaffected by the passage of light through the Earth's atmosphere. Here, we report observations with a new ...
  • Schawinski, K.; Kaviraj, S.; Khochfar, S.; Yoon, S.-J.; Yi, S.K.; Lee, Y.-W.; Deharveng, J.-M.; Boselli, A.; Donas, J.; Milliard, B.; Barlow, T.; Conrow, T.; Forster, K.; Friedman, P.G.; Martin, D.C.; Morrissey, P.; Seibert, M.; Small, T.; Wyder, T.; Neff, S.; Schiminovich, D.; Blanchi, L.; Heckman, T.; Szalay, A.; Madore, B.; Rich, R.M. (2007-12-01)
    We use GALEX near-UV (NUV ) photometry of a sample of early-type galaxies selected in the SDSS (Sloan Digital Sky Survey) to study the UV color-magnitude relation (CMR). NUV - r color is an excellent tracer of even small ...
  • Barnes, J. R.; Jeffers, S. V.; Jones, H.R.A. (2011-04)
    In light of the growing interest in searching for low mass, rocky planets, we investigate the impact of starspots on radial velocity searches for earth-mass planets in orbit about M dwarf stars. Since new surveys targeting ...
  • Gurney, Robert; Rhead, Mike; Martin, Bill; Ramalingam, Soodamani; Cohen, Neil (2013-12-16)
    The UK police service is one of the biggest users of ANPR technology in the world and over a number of years Police Forces have reported variances in ANPR performance based upon the retro-reflectivity properties of UK ...

    © 2015 The Authors. We show that feedback from active galactic nuclei (AGN) plays an essential role in reproducing the down-sizing phenomena, namely: the colour-magnitude relation; specific star formation rates; and the α ...
  • Kaufman, M.; Struck, C.; Elmegreen, B.; Elmegreen, D.M.; Brinks, E.; Thomasson, M.; Klaric, M. (Astronomical Society of the Pacific, 2001)
    We made radio, optical and CO observations of three pairs of spiral galaxies involved in recent, grazing encounters and compared our data with numerical simulations. The tidal structures seen in the galaxy undergoing a ...
  • Shabala, S.; Kaviraj, S.; Silk, J. (2012-08)
    The effects of active galactic nucleus (AGN) feedback on group and cluster galaxies are investigated. We examine the colors of non-AGN hosts (i.e. satellite galaxies) by comparing galaxies overrun by radio AGN with similar ...
