COLOR-MAGNITUDE RELATION AND MORPHOLOGY OF LOW-REDSHIFT ULIRGs IN SLOAN DIGITAL SKY SURVEY
color-magnitude morphological analysis
2014/12/20
We present color-magnitude and morphological analysis of 54 low-redshift ultraluminous infrared galaxies (ULIRGs; 0.018 < z < 0.265 with z median = 0.151), a subset of the Infrared Astronomical Satell...
Ensemble Properties of Comets in the Sloan Digital Sky Survey
COMETS PHOTOMETRY COMETS COMA
2012/2/23
We present the ensemble properties of 31 comets (27 resolved and 4 unresolved) observed by the Sloan Digital Sky Survey (SDSS). This sample of comets represents about 1 comet per 10 million SDSS photo...
A Catalog of Bulge+Disk Decompositions and Updated Photometry for 1.12 Million Galaxies in the Sloan Digital Sky Survey
Decompositions Updated Photometry Galaxies Sloan Digital
2011/9/29
We perform two-dimensional, Point-Spread-Function-convolved, bulge+disk decompositions in the $g$ and $r$ bandpasses on a sample of 1,123,718 galaxies from the Legacy area of the Sloan Digital Sky Sur...
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 ...

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...
