WIYN Integral-Field Kinematics of Disk Galaxies

, 2002
We have completed a new fiber array, SparsePak, optimized for low-surface-brightness studies of extended sources on the WIYN telescope. We are now using this array as a measuring engine of velocity and velocity-dispersion fields of stars and ionized gas ...

An Accreting Supermassive Black Hole Buried in a Faint Dwarf Galaxy

The Astrophysical Journal Letters
In the last decade, there have been several discoveries of active galactic nuclei (AGN) in dwarf galaxies including an AGN in an ultracompact dwarf galaxy with a black hole mass >10 ^6 M _⊙ .

Formation of a Nuclear Star Cluster through a Merger Event in the Low-surface-brightness Galaxy AGC 223218

The Astrophysical Journal
We present the properties of a nuclear star cluster (NSC) in the low-surface-brightness galaxy AGC 223218. The disk of the galaxy can be modeled using two Sérsic components with distinct central positions: one representing the inner bright disk and the ...

A Host Galaxy Morphology Link between Quasiperiodic Eruptions and Tidal Disruption Events

The Astrophysical Journal
The physical processes that produce X-ray quasiperiodic eruptions (QPEs) recently discovered from the nuclei of several low-redshift galaxies are mysterious.

Ultra-diffuse galaxies in the Kilo-Degree Survey with deep learning

Astronomy & Astrophysics
Ultra-diffuse galaxies (UDGs) are a subset of low-surface-brightness galaxies (LSBGs), showing mean effective surface brightness fainter than 24 mag arcsec−2 and a diffuse morphology, with effective radii larger than 1.5 kpc.

Ultradiffuse Galaxies—A Distinct Population? Dwarf Galaxies in the Coma Cluster and A262 from Deep u′–g′–r′ Wendelstein Imaging Data

The Astrophysical Journal Supplement Series
In this study, we compare the structural parameters of ultradiffuse galaxies (UDGs) to those of other dwarf galaxies and investigate whether UDGs form a distinct population.
