Simulating star formation in molecular cloud cores IV. The role of turbulence and thermodynamics
R. E. Attwood, S. P. Goodwin, D. Stamatellos +1
We perform SPH simulations of the collapse and fragmentation of low-mass cores having different initial levels of turbulence (alpha_turb=0.05,0.10,0.25). We use a new treatment of…
A pilot survey of stellar tidal streams in nearby spiral galaxies
David Martinez-Delgado, R. Jay Gabany, Jorge Penarrubia +4
Within the hierarchical framework for galaxy formation, merging and tidal interactions are expected to shape large galaxies to this day. While major mergers are quite rare at prese…
Introducing a Hybrid Method of Radiative Transfer for Smoothed Particle Hydrodynamics
Duncan Forgan, Ken Rice, Dimitris Stamatellos +1
A new means of incorporating radiative transfer into smoothed particle hydrodynamics (SPH) is introduced, which builds on the success of two previous methods - the polytropic cooli…
Galaxies appear simpler than expected
M. J. Disney, J. D. Romano, D. A. Garcia-Appadoo +3
Galaxies are complex systems the evolution of which apparently results from the interplay of dynamics, star formation, chemical enrichment, and feedback from supernova explosions a…
Parity violation constraints using 2006-2007 QUaD CMB polarization spectra
QUaD Collaboration, E. Y. S. Wu, P. Ade +29
We constrain parity-violating interactions to the surface of last scattering using spectra from the QUaD experiment's second and third seasons of observations by searching for a po…
The 6-GHz Multibeam Maser Survey I. Techniques
J. A. Green, J. L. Caswell, G. A. Fuller +22
A new 7-beam 6-7 GHz receiver has been built to survey the Galaxy and the Magellanic Clouds for newly forming high-mass stars that are pinpointed by strong methanol maser emission…
Detection of the 13CO(J=6-5) Transition in the Starburst Galaxy NGC 253
S. Hailey-Dunsheath, T. Nikola, G. J. Stacey +5
We report the detection of 13CO(J=6-5) emission from the nucleus of the starburst galaxy NGC 253 with the redshift (z) and Early Universe Spectrometer (ZEUS), a new submillimeter g…
Results of WEBT, VLBA and RXTE monitoring of 3C 279 during 2006-2007
V. M. Larionov, S. G. Jorstad, A. P. Marscher +2
We present radio-to-optical data taken by the WEBT, supplemented by VLBA and RXTE observations, of 3C 279. Our goal is to use this extensive database to draw inferences regarding t…
Spitzer Spectral Mapping of Supernova Remnant Cassiopeia A
J. D. T. Smith, Lawrence Rudnick, Tracey Delaney +5
We present the global distribution of fine structure infrared line emission in the Cassiopeia A supernova remnant using data from the Spitzer Space Telescope's Infrared Spectrograp…
The properties of brown dwarfs and low-mass hydrogen-burning stars formed by disc fragmentation
Dimitris Stamatellos, Anthony P. Whitworth
We suggest that a high proportion of brown dwarfs are formed by gravitational fragmentation of massive extended discs around Sun-like stars. Such discs should arise frequently, but…
The formation and assembly of a typical star-forming galaxy at z~3
Daniel P. Stark, Mark Swinbank, Richard S. Ellis +3
Recent studies of galaxies ~2-3 Gyr after the Big Bang have revealed large, turbulent rotating systems. The existence of well-ordered rotation in galaxies during this peak epoch of…
LCDM Satellites and HI Companions - The Arecibo ALFA Survey of NGC 2903
J. A. Irwin, G. L. Hoffman, K. Spekkens +11
We have conducted a deep, complete HI survey, using Arecibo/ALFA, of a field centered on the nearby, isolated galaxy, NGC 2903, which is similar to the Milky Way in its properties.…
Supersonic Cloud Collision - I
S. V. Anathpindika
It has long been suggested that shocks might play an important role in altering the form of the interstellar medium (ISM). Shocks enhance gas density and sufficiently dense regions…
Algorithmic comparisons of decaying, isothermal, supersonic turbulence
S. Kitsionas, C. Federrath, R. Klessen +10
Contradicting results have been reported in the literature with respect to the performance of the numerical techniques employed for the study of supersonic turbulence. We aim at ch…
Discovery of a redshift 6.13 quasar in the UKIRT Infrared Deep Sky Survey
D. J. Mortlock, M. Patel, S. J. Warren +10
Optical and near-infrared (NIR) spectra are presented for ULAS J131911.29+095951.4 (hereafter ULAS J1319+0950), a new redshift z = 6.127 +/- 0.004 quasar discovered in the Third Da…
Star Formation at Very Low Metallicity. V. The Greater Importance of Initial Conditions Compared to Metallicity Thresholds
A. -K. Jappsen, M. -M. Mac Low, S. C. O. Glover +2
The formation of the first stars out of metal-free gas appears to result in stars at least an order of magnitude more massive than in the present-day case. We here consider what co…
Galaxy clusters discovered with a Sunyaev-Zel'dovich effect survey
Z. Staniszewski, P. A. R. Ade, K. A. Aird +41
The South Pole Telescope (SPT) is conducting a Sunyaev-Zel'dovich (SZ) effect survey over large areas of the southern sky, searching for massive galaxy clusters to high redshift. I…
On the road to discovery of relic gravitational waves: The TE and BB Correlations in the cosmic microwave background radiation
W. Zhao, D. Baskaran, L. P. Grishchuk
The detection of primordial gravitational waves is one of the biggest challenges of the present time. The existing (Wilkinson Microwave Anisotropy Probe) observations are helpful o…
The formation of brown dwarfs and low-mass stars by disc fragmentation
Dimitris Stamatellos, Anthony P. Whitworth
We suggest that a high proportion of brown dwarfs are formed by gravitational fragmentation of massive, extended discs around Sun-like stars. We argue that such discs should arise…
Introducing a Hybrid Method of Radiative Transfer in Smoothed Particle Hydrodynamics
Duncan Forgan, Ken Rice, Dimitris Stamatellos +1
We present a new method of incorporating radiative transfer into Smoothed Particle Hydrodynamics (SPH). There have been many recent attempts at radiative transfer in SPH (Stamatell…

L. Cortese, G. Gavazzi, A. Boselli
We present estimates of the GALEX NUV and FUV luminosity functions (LFs) of the Coma cluster, over a total area of ~9 deg^2 (~25 Mpc^2), i.e. from the cluster center to the virial…
Cassiopeia A: dust factory revealed via submillimetre polarimetry
L. Dunne, S. J. Maddox, R. J. Ivison +7
If Type-II supernovae - the evolutionary end points of short-lived, massive stars - produce a significant quantity of dust (>0.1 M_sun) then they can explain the rest-frame far-inf…
