The Star Formation History and Evolution of the Ultra-Diffuse M81 Satellite F8D1
Adam Smercina, Eric F. Bell, Benjamin F. Williams +15
We present deep HST imaging of one of the nearest ultra-diffuse galaxies (UDGs) outside of the Local Group: F8D1, a satellite of M81 known to be tidally disrupting. UDGs are an eni…
A Timeline of the M81 Group: Properties of the Extended Structures of M82 and NGC 3077
Benjamin N. Velguth, Eric F. Bell, Adam Smercina +8
Mergers of and interactions between galaxies imprint a wide diversity of morphological, dynamical, and chemical characteristics in stellar halos and tidal streams. Measuring these…
Origins of the Evil Eye: M64's Stellar Halo Reveals the Recent Accretion of an SMC-mass Satellite
Adam Smercina, Eric F. Bell, Paul A. Price +9
M64, often called the "Evil Eye" galaxy, is unique among local galaxies. Beyond its dramatic, dusty nucleus, it also hosts an outer gas disk that counter-rotates relative to its st…
Saying Hallo to M94's Stellar Halo: Investigating the Accretion History of the Largest Pseudobulge Host in the Local Universe
Katya Gozman, Eric F. Bell, Adam Smercina +7
It is not yet settled how the combination of secular processes and merging gives rise to the bulges and pseudobulges of galaxies. The nearby ( 4.2 Mpc) disk galaxy M94 (NGC…
The Saga of M81: Global View of a Massive Stellar Halo in Formation
Adam Smercina, Eric F. Bell, Paul A. Price +7
Recent work has shown that Milky Way-mass galaxies display an incredible range of stellar halo properties, yet the origin of this diversity is unclear. The nearby galaxy M81 cu…
The total mass of the Large Magellanic Cloud from its perturbation on the Orphan stream
D. Erkal, V. Belokurov, C. F. P. Laporte +13
In a companion paper by Koposov et al., RR Lyrae from \textit{Gaia} Data Release 2 are used to demonstrate that stars in the Orphan stream have velocity vectors significantly misal…
