Weak lensing measurements of dark matter halos of galaxies from COMBO-17
Weak lensing measurements of dark matter halos of galaxies from COMBO-17
We present mass estimates for dark matter halos around galaxies from the COMBO-17 survey using weak gravitational lensing. COMBO-17, with photometry in 17 optical filters, provides precise photometric redshifts and spectral classification for objects with . This permits to select and sort lens and source galaxies by their redshifts and …
