Descripción
The first results of HST NICMOS observations of BL Lacertae objects are
presented. Selected target, observed through the F160W filter, are from
the HST "snapshot" survey of BL Lacs (Urry, Scarpa et al. 1999), span
redshifts up to z=0.6. Observations provide reliable color information
for the host galaxy, which in all cases is fully resolved. The
structural parameters of the host are studied, and result compared with
what was found in the R band. Preliminary result indicate that the
integrate color and color profile of the host are fully consistent with
what observed in normal elliptical galaxies.
