Constraining Dust and Molecular Gas Properties in Lyman Alpha Blobs at z 3
(2011-10-07)
In order to constrain the bolometric luminosities, dust properties and molecular gas content of giant Lyman alpha nebulae, the so-called Lyman alpha blobs, we have carried out a study of dust continuum and CO line emission ...
PAndAS in the mist: The stellar and gaseous mass within the halos of M31 and M33
(2012-11-16)
Large scale surveys of the prominent members of the Local Group have provided compelling evidence for the hierarchical formation of massive galaxies, revealing a wealth of substructure that is thought to be the debris from ...
A Hubble Space Telescope NICMOS and ACS Morphological Study of z~2 Submillimetre Galaxies
(2010-02-12)
We present a quantitative morphological analysis using HST NICMOS H160- and ACS I775- band imaging of 25 spectroscopically confirmed submillimetre galaxies (SMGs) which have redshifts between z=0.7-3.4. Our analysis also ...
A Vigorous Starburst in the SCUBA Galaxy N2 850.4
(2003-07-11)
We present optical and near-IR spectroscopy of a z=2.38 hyperluminous IR galaxy, covering the restframe wavelength range from 1000-5000A. It appears to comprise two components separated by less than 1" on the sky (<8kpc); ...
Polytropic model fits to the globular cluster NGC 2419 in Modified Newtonian Dynamics
(2011-10-18)
We present an analysis of the globular cluster NGC 2419, using a polytropic model in Modified Newtonian Dynamics (MOND) to reproduce recently published high quality data of the structure and kinematics of the system. We ...
The tidal trail of NGC205?
(2004-07)
Using data taken as part of the Isaac Newton Telescope Wide Field Camera (INT WFC) survey of M31, we have identified an arc-like overdensity of blue, presumably metal-poor, red giant branch stars in the north-west quadrant ...
A SCUBA Scanmap of the Hubble Deep Field: Measuring the bright end of the sub-mm source counts
(2002-03)
Using the 850 micron SCUBA camera on the JCMT and a scanning technique different from other sub-mm surveys, we have obtained a 125 square arcminute map centered on the Hubble Deep Field. The one-sigma sensitivity to point ...
Periodicity and pitch perception
(1991-10)
There has been experimental evidence pointing to at least two pitch mechanisms, the first involving low-order harmonics that are resolved along the basilar membrane, and the second a periodicity mechanism that depends only ...
Modeling the evolution of infrared luminous galaxies: the influence of the Luminosity-Temperature distribution
(2005-03)
The evolution of the luminous infrared galaxy population is explored using a pure luminosity evolution model which incorporates the locally observed luminosity-temperature distribution for IRAS galaxies. Pure luminosity ...
Periodicity and pitch perception
(1991-10)
There has been experimental evidence pointing to at least two pitch mechanisms, the first involving low-order harmonics that are resolved along the basilar membrane, and the second a periodicity mechanism that depends only ...
