AzTEC Millimetre Survey of the COSMOS Field: I. Data Reduction and Source Catalogue
starburst submillimetre
2014/12/23
We present a 1.1 mm wavelength imaging survey covering 0.3 deg2 in the COSMOS field. These data, obtained with the AzTEC continuum camera on the James Clerk Maxwell Telescope, were centred on a promin...
High Frame-rate Imaging Based Photometry, Photometric Reduction of Data from Electron-multiplying Charge Coupled Devices (EMCCDs)
Instrumentation high angular resolution image processing photometric Gravitational lensing micro
2012/2/24
The EMCCD is a type of CCD that delivers fast readout times and negligible readout noise, making it an ideal detector for high frame rate applications which improve resolution, like lucky imaging or s...

We present the Spitzer IRAC/MUSYC Public Legacy Survey in the Extended CDF-South (SIM-
PLE), which consists of deep IRAC observations covering the 1,600 arcmin2 area surrounding
GOODS-S. The limiti...

We present the Bolocam Galactic Plane Survey (BGPS), a 1.1 mm continuum survey at 3300 e ective resolution of 170 square degrees of the Galactic Plane visible from the northern hemisphere.The BGPS is ...
Spectrophotometric Redshifts. A New Approach to the Reduction of Noisy Spectra and its Application to GRB090423
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/27
We have developed a new method, close in philosophy to the photometric redshift technique, which can be applied to spectral data of very low signal-to-noise ratio. Using it we intend to measure redshi...
An optical/NIR survey of globular clusters in early-type galaxies. I. Introduction and data reduction procedures
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
The combination of optical and near-infrared (NIR) colours has the potential to break the age/metallicity degeneracy and offers a better metallicity sensitivity than optical colours alone.
Determining Absorption, Emissivity Reduction, and Local Suppression Coefficients inside Sunspots
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
The power of solar acoustic waves is reduced inside sunspots mainly due to absorption, emissivity reduction, and local suppression. The coefficients of these power-reduction mechanisms can be determin...
