Abstract

The giant early-type merger remnant galaxy NGC 1316 is an ideal probe for\nstudying the long-term effects of a major merger on its globular cluster (GC)\nsystem, given its spectroscopically derived merger age of 3 Gyr which we\nreported in a recent paper. Here we report several pieces of photometric\nevidence showing that the second-generation GCs in NGC 1316 are at an\nevolutionary phase in between that of luminous GCs found in younger merger\nremnants such as (e.g.) NGC 7252 and that of `red' GCs found in `normal, old'\nellipticals. The observation that massive, second-generation GCs formed during\nmajor mergers can survive for at least 3 Gyr provides strong evidence that\nthese clusters can have `normal' mass functions including low-mass stars, and\nhence that they can survive to reach `old age' similar to those of `normal'\nellipticals.\n
