Galaxy Pairs in the Sloan Digital Sky Survey - III: Evidence of Induced Star Formation from Optical Colours
Galaxy Pairs the Sloan Digital Sky Survey - III
2011/1/11
We have assembled a large, high quality catalogue of galaxy colours from the Sloan Digital Sky Survey Data Release 7, and have identified 21,347 galaxies in pairs spanning a range of projected separat...
Counts-in-Cylinders in the Sloan Digital Sky Survey with Comparisons to N-body Simulations
Counts-in-Cylinders the Sloan Digital Sky Survey
2011/1/11
Environmental statistics provide a necessary means of comparing the properties of galaxies in different environments and a vital test of models of galaxy formation within the prevailing, hierarchical ...
Spectral variability of quasars from multi-epoch photometric data in the Sloan Digital Sky Survey Stripe 82
Spectral variability multi-epoch photometric data
2011/1/11
We present a new approach to analysing the dependence of quasar variability on rest-frame wavelengths. We exploited the spectral archive of the Sloan Digital Sky Survey (SDSS) to create a sample of mo...
Metallicities and dust content of proximate damped Lyman alpha systems in the Sloan Digital Sky Survey
Metallicities dust content proximate damped Lyman alpha systems
2011/1/11
Composite spectra of 85 proximate absorbers (log N(HI)>20 and velocity difference between the absorption and emission redshift, dv<10,000 km/s) in the SDSS are used to investigate the trends of metal ...
The Properties of Type Ia Supernova Host Galaxies from the Sloan Digital Sky Survey

2010/11/12
We investigate the properties and environments of Type Ia Supernova (SN Ia) host galaxies in
the Stripe 82 of the Sloan Digital Sky Survey-II Supernova Survey centered on the celestial equator.Host g...
Photometric Catalogue of Quasars and Other Point Sources in the Sloan Digital Sky Survey
astronomical data bases miscellaneous – catalogues – techniques pho-tometric – methods statistical – surveys
2010/11/12
We present a catalogue of about 8.6 million unresolved photometric detections in the Sloan Digital Sky Survey Seventh Data Release classifying them into stars, galaxies and quasars using a machine lea...
