The Aspen--Amsterdam Void Finder Comparison Project
Joerg M. Colberg, Frazer Pearce, Caroline Foster +16
Despite a history that dates back at least a quarter of a century studies of voids in the large--scale structure of the Universe are bedevilled by a major problem: there exist a la…
Observations of the Naked-Eye GRB 080319B: Implications of Nature's Brightest Explosion
J. S. Bloom, D. A. Perley, W. Li +18
The first gamma-ray burst (GRB) confirmed to be bright enough to be seen with the naked eye, GRB 080319B at redshift z = 0.937, allowed for exquisite follow-up observations across…
Monte Carlo Simulations of Star Clusters - IV. Calibration of the Monte Carlo Code and Comparison with Observations for the Open Cluster M67
Mirek Giersz, Douglas C. Heggie, Jarrod R. Hurley
We outline the steps needed in order to incorporate the evolution of single and binary stars into a particular Monte Carlo code for the dynamical evolution of a star cluster. We ca…
The early-type galaxies NGC 1407 and NGC 1400 - I: spatially resolved radial kinematics and surface photometry
Max Spolaor, Duncan A. Forbes, George K. T. Hau +2
This is the first paper of a series focused on investigating the star formation and evolutionary history of the two early-type galaxies NGC 1407 and NGC 1400. They are the two brig…
Four Faint T Dwarfs from the UKIRT Infrared Deep Sky Survey (UKIDSS) Southern Stripe
Kuenley Chiu, Michael C. Liu, Linhua Jiang +6
We present the optical and near-infrared photometry and spectroscopy of four faint T dwarfs newly discovered from the UKIDSS first data release. The sample, drawn from an imaged ar…
Detection of SiO emission from a massive dense cold core
N. Lo, M. Cunningham, I. Bains +2
We report the detection of the SiO (J = 2 - 1) transition from the massive cold dense core G333.125-0.562. The core remains undetected at wavelengths shorter than 70 micron and has…
Comprehensive simulations of superhumps
Amanda J. Smith, Carole A. Haswell, James R. Murray +2
(Abridged) We use 3D SPH calculations with higher resolution, as well as with more realistic viscosity and sound-speed prescriptions than previous work to examine the eccentric ins…
When do early-type galaxies form?
Roberto G. Abraham, Patrick J. McCarthy, Erin Mentuch +13
We have used the Hubble Space Telescope's Advanced Camera for Surveys to measure the mass density function of morphologically selected early-type galaxies in the Gemini Deep Deep S…
HVC and IVC gas in the halo of the Milky Way
Nadya Ben Bekhti, Philipp Richter, Tobias Westmeier
We combine CaII/NaI absorption and HI 21 cm emission line measurements to analyse the metal abundances, the distribution, the small-scale structure, and the physical conditions of…
SPH simulations of accretion flow via Roche lobe overflow and via mass transfer from Be disk
Kimitake Hayasaki, Atsuo T. Okazaki, James. R. Murray
We compare the accretion flow onto the neutron star induced by Roche lobe overflow with that by the overflow from the Be disk, in a zero eccentricity, short period binary with the…
Long-term evolution of accretion disks around the neutron star in Be/X-ray binaries
Kimitake Hayasaki, Atsuo T. Okazaki
we study the long-term evolution of the accretion disk around the neutron star in Be/X-ray binaries. We confirm the earlier result by Hayasaki & Okazaki (2004) that the disk evolve…
Abundance Anomalies in NGC6752 - Do AGB Stars Have a Role?
S. W. Campbell, Y. Fenner, A. I. Karakas +2
We are in the process of testing a popular theory that the observed abundance anomalies in the Globular Cluster NGC 6752 are due to `internal pollution' from intermediate mass asym…
A Dark Hydrogen Cloud in the Virgo Cluster
Robert Minchin, Jonathan Davies, Michael Disney +8
VIRGOHI21 is an HI source detected in the Virgo Cluster survey of Davies et al. (2004) which has a neutral hydrogen mass of 10^8 M_solar and a velocity width of Delta V_20 = 220 km…
The Australian experience with the PC-EVN recorder
R. Dodson, S. Tingay, C. West +4
We report on our experiences using the Metsahovi Radio Observatory's (MRO) VLBI Standard Interface (VSI, Whitney 2002) recorder in a number of astronomical applications. The PC-EVN…
Non-axisymmetric Structure of Accretion Disks in Be/X-ray Binaries
Kimitake Hayasaki, Atsuo T. Okazaki
The non-axisymmetric structure of accretion disks around the neutron star in Be/X-ray binaries is studied by analyzing the results from three dimensional (3D) Smoothed Particle Hyd…
Heating of Galactic Disks by Infalling Satellites
A. J. Benson, C. G. Lacey, C. S. Frenk +2
We develop an analytic model to calculate the rate at which galaxy disks are heated by dark matter substructures orbiting in their halos. The model takes into account the internal…
Neutral Hydrogen in Galaxy Groups
N. P. F. McKay, C. G. Mundell, S. Brough +2
We present preliminary results from a study of the neutral hydrogen (HI) properties of an X-ray selected sample of nearby loose galaxy groups. This forms part of a multi-wavelength…
