A CH3CN and HCO+ survey towards southern methanol masers associated with star formation
C. R. Purcell, R. Balasubramanyam, M. G. Burton +32
We present the initial results of a 3-mm spectral line survey towards 83 methanol maser selected massive star-forming regions. Here we report observations of the J=5-4 and 6-5 rota…
The formation of brown dwarfs
A. P. Whitworth, S. P. Goodwin
We review four mechanisms for forming brown dwarfs: (i) turbulent fragmentation (producing very low-mass prestellar cores); (ii) gravitational instabilities in discs; (iii) dynamic…
An investigation of the submillimeter background radiation using SCUBA and Spitzer
S. Dye, S. A. Eales, M. L. N. Ashby +8
We investigate the redshift dependence of the contribution to the extragalactic far-infrared/sub-millimeter background from galaxies detected by the Spitzer Space Telescope at 8um…
Optical/near-infrared colours of early-type galaxies and constraints on their star formation histories
P. A. James, M. Salaris, J. I. Davies +2
(abridged) We introduce and discuss the properties of a theoretical (B-K)-(J-K) integrated colour diagram for single-age, single-metallicity stellar populations. This combination o…
Resolution requirements for simulating gravitational fragmentation using SPH
D. A. Hubber, S. P. Goodwin, A. P. Whitworth
Jeans showed analytically that, in an infinite uniform-density isothermal gas, plane-wave perturbations collapse to dense sheets if their wavelength, , satisfies $λ> λ_{_{\rm JE…
kappa-Minkowski representations on Hilbert spaces
Alessandra Agostini
The algebra of functions on kappa-Minkowski noncommutative spacetime is studied as algebra of operators on Hilbert spaces. The representations of this algebra are constructed and c…
Joint LIGO and TAMA300 Search for Gravitational Waves from Inspiralling Neutron Star Binaries
LIGO Scientific Collaboration, TAMA Collaboration
We search for coincident gravitational wave signals from inspiralling neutron star binaries using LIGO and TAMA300 data taken during early 2003. Using a simple trigger exchange met…
Search for gravitational wave bursts in LIGO's third science run
LIGO Scientific Collaboration
We report on a search for gravitational wave bursts in data from the three LIGO interferometric detectors during their third science run. The search targets subsecond bursts in the…
Observational characteristics of dense cores with deeply embedded young protostars
D. Stamatellos, A. P. Whitworth, S. P. Goodwin
Class 0 objects, which are thought to be the youngest protostars, are identified in terms of NIR or radio emission and/or the presence of molecular outflows. We present combined hy…
Expected coalescence rates of NS-NS binaries for laser beam interferometers
J. A. de Freitas Pacheco, T. Regimbau, S. Vincent +1
The coalescence rate of two neutron stars (NS) is revisited. For estimation of the number of bound NS-NS and the probability of their coalescence in a timescale , the galactic s…
Best Simultaneous Diophantine Approximations under a Constraint on the Denominator
Iskander Aliev, Peter Gruber
We investigate the problem of best simultaneous Diophantine approximation under a constraint on the denominator, as proposed by Jurkat. New lower estimates for optimal approximatio…
Bolocam Survey for 1.1 mm Dust Continuum Emission in the c2d Legacy Clouds. I. Perseus
M. L. Enoch, K. E. Young, J. Glenn +14
We have completed a 1.1 mm continuum survey of 7.5 sq deg of the Perseus Molecular Cloud using Bolocam at the Caltech Submillimeter Observatory. This represents the largest millime…
COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses II. SDSS J0924+0219: the redshift of the lensing galaxy, the quasar spectral variability and the Einstein rings
A. Eigenbrod, F. Courbin, S. Dye +6
(Abridged) We present our VLT/FORS1 deep spectroscopic observations of the gravitationally lensed quasar SDSS J0924+0219, as well as archival HST/NICMOS and ACS images of the same…
Search for gravitational waves from binary black hole inspirals in LIGO data
LIGO Scientific Collaboration, B. Abbott et. al
We report on a search for gravitational waves from binary black hole inspirals in the data from the second science run of the LIGO interferometers. The search focused on binary sys…
First ground-based 200-um observing with THUMPER on JCMT - sky characterisation and planet maps
D. Ward-Thompson, P. A. R. Ade, H. Araujo +19
We present observations that were carried out with the Two HUndred Micron PhotometER (THUMPER) mounted on the James Clerk Maxwell Telescope (JCMT) in Hawaii, at a wavelength of 200…
Origin of the inner ring in photoluminescence patterns of quantum well excitons
A. L. Ivanov, L. E. Smallwood, A. T. Hammack +3
In order to explain and model the inner ring in photoluminescence (PL) patterns of indirect excitons in GaAs/AlGaAs quantum wells (QWs), we develop a microscopic approach formulate…
A Fluctuation Analysis of the Bolocam 1.1mm Lockman Hole Survey
Philip R. Maloney, Jason Glenn, James E. Aguirre +13
We perform a fluctuation analysis of the 1.1mm Bolocam Lockman Hole Survey, which covers 324 square arcmin to a very uniform point source-filtered RMS noise level of 1.4 mJy/beam.…
First all-sky upper limits from LIGO on the strength of periodic gravitational waves using the Hough transform
LIGO Scientific Collaboration, B. Abbott
We perform a wide parameter space search for continuous gravitational waves over the whole sky and over a large range of values of the frequency and the first spin-down parameter.…
A Dark Galaxy in the Virgo Cluster Imaged at 21-cm
R. F. Minchin, J. I. Davies, M. J. Disney +10
Dark Matter supposedly dominates the extragalactic, yet no totally dark structure of galactic proportions has ever been convincingly identified. Earlier (Minchin et al. 2005) we su…
