Abstract:
We present a study of tidal debris associated with 126 nearby red
galaxies, selected from the 1.2°2 Multiwavelength Survey by
Yale-Chile (MUSYC, Cat. J/ApJS/162/1) and the 9.3°2 NOAO Deep
Wide-Field Survey (Jannuzi & Dey, 1999ASPC..191..111J 1999ASPC..191..111J). In the full
sample, 67 galaxies (53%) show morphological signatures of tidal
interactions consisting of broad fans of stars, tails, and other
asymmetries at very faint surface brightness levels. When restricting
the sample to the 86 bulge-dominated early-type galaxies, the fraction
of tidally disturbed galaxies rises to 71%, which implies that for
every "normal" undisturbed elliptical there are two that show clear
signs of interactions. The tidal features are red and smooth and often
extend over >50kpc.

Note (1): Tidal feature, defined as follows:
0 = no tidal features;
1 = weak features;
2 = strong features;
3 = an ongoing interaction with another galaxy.
Note (2): The tidal parameter (describing the level of distortion)
measures the median absolute deviation of the (fractional)
residuals from the model fit (see text).
