X-rays from the jet in 3C 273: clues from the radio-optical spectra
S. Jester, H. -J. Roeser, K. Meisenheimer +1
Using new deep VLA and HST observations of the large-scale jet in 3C273 matched to 0.3" resolution, we have detected excess near-ultraviolet emission (300 nm) above a synchrotron c…
Classification and Redshift Estimation in Multi-Color Surveys
Christian Wolf, Klaus Meisenheimer, Hermann-Josef Röser
We present a photometric method for identifying stars, galaxies and quasars in multi-color surveys and estimating multi-color redshifts for the extragalactic objects. We use a libr…
Multi-color Classification in the Calar Alto Deep Imaging Survey
C. Wolf, K. Meisenheimer, H. -J. Röser +12
We use a multi-color classification method introduced by Wolf, Meisenheimer & Roeser (2000) to reliably identify stars, galaxies and quasars in the up to 16-dimensional color space…
Object Classification in Astronomical Multi-Color Surveys
C. Wolf, K. Meisenheimer, H. -J. Röser
We present a photometric method for identifying stars, galaxies and quasars in multi-color surveys, which uses a library of >65000 color templates. The method aims for extracting t…
The Surface Density of Extremely Red Objects
D. Thompson, S. V. W. Beckwith, R. Fockenbrock +10
We present initial results from a field survey for extremely red objects (EROs, defined here as (R-K') >= 6 mag) covering 154 square arcminutes of sky, from the first of 7 deep, wi…
