Forward and Back: Kinematics of the Palomar 5 Tidal Tails [PDF]
The tidal tails of Palomar 5 (Pal 5) have been the focus of many spectroscopic studies in an attempt to identify individual stars lying along the stream and characterise their kinematics. The well-studied trailing tail has been explored out to a distance

Existence of tidal tails for the globular cluster NGC 5824 [PDF]
Context. Several dynamically cold streams have been associated with certain globular clusters (GCs) based on orbital energies and angular momenta. Some of these streams are surprisingly far apart from their progenitors and one such pair is Triangulum and

Kinematics in galactic tidal tails [PDF]
[abridged] In this work we study in detail the kinematics of tidal debris stars to investigate the implications of the new scenario that the observed sample of Hypervelocity stars could partly originate from a dwarf-host galaxy collision. We use a suite of N-body simulations following the encounter of a satellite galaxy with its Milky Way-type host ...

Estimating the Ages of Open Star Clusters from Properties of Their Extended Tidal Tails [PDF]
The most accurate current methods for determining the ages of open star clusters, stellar associations, and stellar streams are based on isochrone fitting or the lithium depletion boundary.

Tidal tails in the disintegrating open cluster NGC 752 [PDF]
We utilize the robust membership determination algorithm, ML-MOC, on the precise astrometric and deep photometric data from Gaia Early Data Release 3 within a region of radius 5◦ around the center of the intermediate-age galactic open cluster NGC 752 to ...

Absence of obvious tidal tails around the globular cluster NGC 6397 [PDF]
In this work, we use N-body simulations performed on GPU to trace the past 10 Gyr dynamical history of a globular cluster (GC) similar to NGC 6397 in the tidal field of a Milky Way-like galaxy and we compare our simulated GCs with data from the third ...

The Effect of Dwarf Galaxies on the Tidal Tails of Globular Clusters [PDF]
The tidal tails of globular clusters have been shown to be sensitive to the external tidal field. We investigate how Galactic globular clusters with observed tails are affected by satellite dwarf galaxies by simulating tails in galaxy models with and ...

Two tails in NGC 3656, and the major merger origin of shell and minor axis dust lane ellipticals [PDF]
I report on the discovery of two faint (~ 26.8 Rmag/arcsec^2) tidal tails around the shell elliptical NGC 3656 (Arp 155). This galaxy had previously been interpreted as a case of accretion, or minor merger.

The orientation and kinematics of inner tidal tails around dwarf galaxies orbiting the Milky Way [PDF]
Using high-resolution collisionless N-body simulations we study the properties of tidal tails formed in the immediate vicinity of a two-component dwarf galaxy evolving in a static potential of the Milky Way (MW).
