Praesepe (NGC 2632) and its tidal tails [PDF]

Astronomy & Astrophysics, 2019
Within a 400 pc sphere around the Sun, we search for Praesepe's tidal tails in the Gaia DR2 dataset. We used a modified convergent-point method to search for stars with space velocities close to the space velocity of the Praesepe cluster. We find a clear

Tidal Tails and Galaxy Evolution [PDF]

Astronomical & Astrophysical Transactions, 2000
We review recent results on the tidal structures of spiral galaxies. Topics included are general characteristics of tails; kinematics of tidal structures and dark haloes of host galaxies; frequency of tidal distortions at z~1.Comment: 5 pages ...

Tidal tails of open clusters [PDF]

Astronomy & Astrophysics
Open clusters that emerged from the star-forming regions as gravitationally bound structures are subjected to star evaporation, ejection, and tidal forces throughout the rest of their lives.

The Tidal Tails of 47 Tucanae [PDF]

Monthly Notices of the Royal Astronomical Society, 2012
The Galactic globular cluster 47 Tucanae (47 Tuc) shows a rare increase in its velocity dispersion profile at large radii, indicative of energetic, yet bound, stars at large radii dominating the velocity dispersion and, potentially, of ongoing ...

The tidal tails of NGC 2298 [PDF]

Monthly Notices of the Royal Astronomical Society, 2011
We present an implementation of the matched-filter technique to detect tidal tails of globular clusters. The method was tested using SDSS data for the globular cluster Palomar 5 revealing its well known tidal tails. We also ran a simulation of a globular

Tidal tails in CDM cosmologies [PDF]

, 1998
We study the formation of tidal tails in pairs of merging disk galaxies with structural properties motivated by current theories of cold dark matter (CDM) cosmologies.

Tidal tails of nearby open clusters. I. Mapping with Gaia DR3 [PDF]

Astronomy & Astrophysics
Tidal tails of open clusters are the result of stellar evaporation from the cluster through the Galactic potential and internal dynamics. With the recent availability of high-precision data, tidal tails are being detected for most of the nearby open ...

The Tidal Tails of NGC 5466 [PDF]

Monthly Notices of the Royal Astronomical Society, 2007
The study of substructure in the stellar halo of the Milky Way has made a lot of progress in recent years, especially with the advent of surveys like the Sloan Digital Sky Survey.

Quenching through Tidal Gas Removal: Molecular Gas and Star Formation in Tidal Tails of z ∼ 0.7 Post-starburst Galaxies

The Astrophysical Journal
The active suppression of star formation in galaxies is critical for preventing the growth of overly massive systems and explaining the formation of present-day elliptical galaxies.

Hyades tidal tails revealed by Gaia DR2 [PDF]

Astronomy & Astrophysics, 2018
Aims. Within a 200 pc sphere around the Sun, we search for the Hyades tidal tails in the Gaia DR2 dataset. Methods. We used a modified convergent-point method to search for stars with space velocities close to the space velocity of the Hyades cluster ...
