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 ...

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 ...

Anatomy of the Star Formation in a Tidally Disturbed Disk Galaxy: NGC 3718

The Astrophysical Journal
We present a UV, optical, and near-IR study of the star-forming complexes in the nearby peculiar galaxy NGC 3718, using Ultraviolet Imaging telescope, Galaxy Evolution Explorer, Spitzer, and DECam Legacy Survey imaging data.

Self-similar Buildup and Inside-out Growth: Tracing the Evolution of Intermediate-to-high-mass Star-forming Galaxies since z = 2

The Astrophysical Journal
We aim to discern scenarios of structural evolution of intermediate-to-high-mass star-forming galaxies (SFGs) since cosmic noon by comparing their stellar mass profiles with present-day stellar masses of $\mathrm{log}({M}_{* ,0}/{M}_{\odot })=10.3-11 ...

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.
