Merger-driven or Internal Evolution? A New Morphological Study of Tidal Disruption Event Host Galaxies

The Astrophysical Journal Letters
The host galaxies of tidal disruption events (TDEs) show enhanced central stellar concentration and are preferentially found in poststarburst and green valley populations.

Inner bars also buckle - The MUSE TIMER view of the double-barred galaxy NGC 1291

, 2018
Double bars are thought to be important features for secular evolution in the central regions of galaxies. However, observational evidence about their origin and evolution is still scarce.

Survival or Destruction: Effects of Spheroidal Satellite Collisions on Bars in Milky Way–like Galaxies

The Astrophysical Journal
Although stellar bars are prevalent in local galaxies, unbarred galaxies constitute a significant fraction, particularly at high redshifts. While some galaxies are unbarred by nature due to stability against the bar instability, several mechanisms ...

Bar Instability and Formation Timescale across Toomre’s Q Parameter and Central Mass Concentration: Slow Bar Formation or True Stability

The Astrophysical Journal
We investigate the bar formation process using N -body simulations across the Toomre’s parameter Q ${}_{{\rm{\min }}}$ and central mass concentration (CMC), focusing principally on the formation timescale.

Solution of the dark matter riddle within standard model physics: from black holes, galaxies and clusters to cosmology

Frontiers in Astronomy and Space Sciences
It is postulated that the energy density of the (quantum) vacuum acts firstly as dark energy and secondly as a part of dark matter. Assisted by electric fields arising from a small charge mismatch in the cosmic plasma, it can condense on mass ...

The Dependency of Bar Formation Timescale on Disk Mass Fraction, Toomre Q, and Scale Height

The Astrophysical Journal
Bars are one of the most prominent galactic structures. The classical swing-amplification theory can qualitatively describe the spontaneous bar instability of stellar disks.

Dependency of the Bar Formation Timescale on the Halo Spin

The Astrophysical Journal
Bars are among the most prominent structures in disk galaxies. While the widely accepted swing-amplification theory provides a qualitative framework for their formation, the detailed physical processes remain incompletely understood.
