A Closer Look at the Extended Edge-on Low-surface Brightness Galaxies

The Astrophysical Journal
To understand the origin of extended disks of low-surface brightness (LSB) galaxies, we studied in detail four such systems with large disks seen edge on. Two of them are edge-on giant LSB galaxies (gLSBGs) recently identified by our team.

Zangetsu: A Candidate Isolated, Quiescent, and Backsplash Ultra-diffuse Galaxy in the COSMOS Field

The Astrophysical Journal
Deep imaging surveys have changed our view of the low surface brightness (LSB) Universe. The “renaissance” of the LSB galaxy population, as a prime example of this recent development, continues to challenge our understanding of galaxy formation. Here, we

MUSE Study of Two Giant Low-surface-brightness Galaxies with Compact Satellites

The Astrophysical Journal
Giant low-surface-brightness galaxies (gLSBGs) are rare objects with disk radii up to 160 kpc and dynamical masses of up to the order of 10 ^12 M _⊙ . Their very existence challenges currently accepted theories of galaxy formation and evolution, as it is

The ISM of Low Surface Brightness Galaxies

, 2000
Using Monte Carlo radiative transfer techniques, we model the dust content of the edge-on low surface brightness (LSB) galaxy UGC 7321 and explore the effects of dust on its disk color gradients. Dust alone cannot explain the large radial disk color gradients observed in this galaxy and we find that a significant fraction (~50%) of the dust in UGC 7321

Are Gas-rich Ultra-diffuse Galaxies and Field Dwarfs Distinct?

The Astrophysical Journal
We explore the differences in gas-rich field ultra-diffuse galaxies (UDGs) and diffuse classical dwarf galaxies using an extensive atomic gas (H I ) follow-up survey of optically selected UDG candidates from the Systematically Measuring Ultra-diffuse ...

Characterising bars in low surface brightness galaxies

, 2018
In this paper, we use $\textit{B}$-band, $\textit{I}$-band, and 3.6 $ $m azimuthal light profiles of four low surface brightness (LSB) galaxies (UGC 628, F568-1, F568-3, F563-V2) to characterise three bar parameters: length, strength, and corotation radius.

Ultradiffuse Galaxies in the EAGLE Simulation

The Astrophysical Journal
We use the highest-resolution EAGLE simulation, Recal-L025N0752, to study the properties and formation of ultradiffuse galaxies (UDGs). We identify 181 UDGs at z = 0 and find their properties are consistent with observations.
