Identifying Old Tidal Dwarf Irregulars [PDF]

open access: yes, 2000
We examine the observational consequences of the two possible origins for irregular galaxies: formation from collapse of a primordial cloud of gas early in the age of the Universe, and formation from tidal tails in an interaction that could have occured ...

Constraining the Gravitational Potential from the Projected Morphology of Extragalactic Tidal Streams

open access: yesThe Astrophysical Journal, 2023
The positions and velocities of stellar streams have been used to constrain the mass and shape of the Milky Way's dark matter halo. Several extragalactic streams have already been detected, though it has remained unclear what can be inferred about the ...

Tidal Tails around Globular Clusters

open access: yes, 2008
We present the results of detailed N-body simulations of clusters moving in a realistic Milky Way potential. The strong interaction with the bulge and the disk of the Galaxy leads to the formation of tidal tails, emanating from opposite sides of the cluster.

About the morphology of dwarf spheroidal galaxies and their dark matter content [PDF]

open access: yes, 2003
The morphological properties of the Carina, Sculptor and Fornax dwarfs are investigated using new wide field data with a total area of 29 square degrees.

APOGEE Detection of N-rich stars in the tidal tails of Palomar 5 [PDF]

open access: yes, 2021
Recent results from chemical tagging studies using APOGEE data suggest a strong link between the chemical abundance patterns of stars found within globular clusters, and chemically peculiar populations in the Galactic halo field. In this paper we analyse

S5: New insights from deep spectroscopic observations of the tidal tails of the globular clusters NGC 1261 and NGC 1904 [PDF]

open access: yesAstronomy & Astrophysics
As globular clusters (GCs) orbit the Milky Way, their stars are tidally stripped and form tidal tails that follow the orbit of the cluster around the Galaxy.

Dwarf Galaxies and Star Clusters in Tidal Tails [PDF]

open access: yesSymposium - International Astronomical Union, 2002
We summarize the properties of tidal dwarf candidates in a sample of interacting galaxies and classify objects in tidal tails depending on their morphological appearance. New high-resolution dynamical models are needed to understand how the different structures seen in tidal tails are formed.

The Star Cluster Population in the Tidal Tails of NGC 6872

open access: yes, 2005
We present a photometric analysis of the rich star cluster population in the tidal tails of NGC 6872. We find star clusters with ages between 1 - 100 Myr distributed in the tidal tails, while the tails themselves have an age of less than 150 Myr. Most of

The symmetries and scaling of tidal tails in galaxies [PDF]

open access: yes, 2012
(Abriged) We present analytic models for the formation and evolution of tidal tails and related structures following impulsive disturbances in galaxy collisions.
