We investigate the dynamical state of a new class of extended star clusters known as "faint fuzzies," which were discovered in two nearby S0 galaxies, NGC 1023 and NGC 3384. It is shown that the faint fuzzies of NGC 1023 lie in a fast-rotating ringlike structure within the galactic disk with mean radius of 5 kpc, rotational velocity of 200 km s-1, and velocity dispersion of 115 km s-1. We propose a scenario for the origin of faint fuzzies that is connected to the origin of S0 galaxies as a…

THE STAR CLUSTER POPULATION OF THE COLLISIONAL RING GALAXY NGC 922

We present a detailed study of the star cluster population detected in the galaxy NGC 922, one of the closest collisional ring galaxies known to date, using Hubble Space Telescope/Wide Field

The nature of faint fuzzies from the kinematics of NGC 1023

Faint fuzzies are metal-rich apparently-old star clusters with unusually large radii (7-15 pc), found mostly in S0 galaxies, whose source remain obscure. To identify their origins, we compare

The Spatial Distribution of Faint Fuzzy Star Clusters in NGC 5195

We present a study of a faint fuzzy star cluster system in the nearby SB0 galaxy NGC 5195 interacting with the famous spiral galaxy NGC 5194 (M51), based on HST ACS BVI mosaic images taken by the

Testing the nature of S0 galaxies using planetary nebula kinematics in NGC 1023

We investigate the manner in which lenticular galaxies are formed by studying their stellar kinematics: an S0 formed from a fading spiral galaxy should display similar cold outer disc kinematics to

The formation of compact dwarf ellipticals through merging star clusters

In the past decades, extended old stellar clusters have been observed. These extended objects cover a large range in masses, from extended clusters or faint fuzzies to ultracompact dwarf galaxies.

FAINT FUZZY STAR CLUSTERS IN NGC 1023 AS REMNANTS OF MERGED STAR CLUSTER COMPLEXES

In the lenticular galaxy NGC 1023 a third population of globular clusters (GCs), called faint fuzzies (FFs), was discovered next to the blue and red GC populations by Larsen & Brodie. While these FFs

We present a study of compact star clusters in the nearby pair of interacting galaxies NGC 5194/5195 (M51), based on multifilter Hubble Space Telescope (HST) WFPC2 archival images. We have detected

The baryonic dark matter dominating the structures of galaxies is widely considered as mysterious, but hints for it have been in fact detected in several astronomical observations at optical,

Context. In the last decade, very extended old stellar clusters with m asses in the range from a few 10 4 to 10 8 Mhave been found in various types of galaxies in different environments. Objects with

Extended star clusters in NGC 1023 from HST/ACS mosaic imaging

Faint fuzzies are a relatively new class of star cluster, first found in the nearby S0 galaxy NGC 1023 by Larsen & Brodie using WFPC2 images from the Hubble Space Telescope (HST). Here we investigate

The Possible Origin of the Faint Fuzzy Star Clusters in NGC 1023

In the lenticular galaxy NGC 1023 a new population of star clusters ("faint fuzzies") was recently discovered by Larsen & Brodie. These clusters are found inside the disk and are faint (23 ≤ V ≤ 24
