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...
Photometric redshifts for GRB afterglows from GROND and Swift/UVOT
gamma rays bursts Techniques photometric
2010/11/11
Aims. We present a framework to obtain photometric redshifts (photo-zs) for gamma-ray burst afterglows. Using multi-band photometry from GROND and Swift/UVOT, photo-zs are derived for five GRBs for wh...
Spatially Resolved Star Formation History Along the Disk of M82 Using Multi-Band Photometric Data
galaxies individual (M82)– galaxies formation– galaxies star clusters
2010/11/12
We present the results on the star formation history and extinction in the disk of M82 over
spatial scales of 10′′ (180 pc). Multi-band photometric data covering from the far ultraviolet to the near...
