Properties of Galaxies with Counter-rotating Stellar Disks in the MaNGA Survey

The Astrophysical Journal
The gas accretion process can fuel both star formation and black hole activity, playing a critical role in galaxy evolution. The counter-rotating structures are believed to originate from gas accretion, serving as an ideal laboratory to study its impact ...

Project AMIGA: The Inner Circumgalactic Medium of Andromeda from Thick Disk to Halo

The Astrophysical Journal
The inner circumgalactic medium (CGM) of galaxies, where disk and halo processes intersect, remains poorly characterized despite its critical role in regulating galaxy evolution.

Galactokinetics

The Astrophysical Journal
Galactic disks lie at the heart of many astrophysical puzzles. There are sophisticated kinetic theories that describe some aspects of galaxy disk dynamics, but extracting quantitative predictions from those theories has proven very difficult, meaning ...

Discovering the Mass-Scaled Damping Timescale from Microquasars to Blazars

The Astrophysical Journal Letters
Studying the variability of the accretion disks of black holes and jets is important to identify their internal physical processes. In this Letter, we obtain the characteristic damping timescale of 34 blazars and 7 microquasars from the Fermi-Large Area ...

Warps in disk galaxies

, 2001
Volgens de huidige inzichten is het universum zo’n 15 miljard jaar geleden ontstaan als een grote explosie die de Oerknal wordt genoemd. Sinds de oerknal dijt het universum uit, hoewel de zwaartekracht van de materie in het heelal deze uitdijing wat afremt.
