The low-mass and structured stellar halo of M83 argues against a merger origin for its starburst and extended neutral hydrogen disk
Eric F. Bell, Benjamin Harmsen, Matthew Cosby +12
A merger origin has been suggested for M83's massive, metal-rich extended HI disk and nuclear starburst. We observe M83's stellar halo to test this idea. We train nearest-neighbor…
Andromeda XXXV: The Faintest Dwarf Satellite of the Andromeda Galaxy
Jose Marco Arias, Eric F. Bell, Katya Gozman +8
We present the discovery of Andromeda XXXV, the faintest Andromeda satellite galaxy discovered to date, identified as an overdensity of stars in the Pan-Andromeda Archaeological Su…
Exploring the Diversity of Faint Satellites in the M81 Group
Katya Gozman, Eric F. Bell, In Sung Jang +9
In the last decade, we have been able to probe further down the galaxy luminosity function than ever before and expand into the regime of ultra-faint dwarfs (UFDs), which are some…
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…
First resolved stellar halo kinematics of a MW-mass galaxy outside the Local Group: A flat counter-rotating halo in NGC 4945
Camila Beltrand, Antonela Monachesi, Richard D'Souza +6
Stellar halos of galaxies, primarily formed through the accretion of smaller objects, are important to understand the hierarchical mass assembly of galaxies. However, the inner reg…
Constraining the assembly time of the stellar haloes of nearby Milky Way-mass galaxies through AGB populations
Benjamin Harmsen, Eric F. Bell, Richard D'Souza +5
The star formation histories (SFHs) of galactic stellar haloes offer crucial insights into the merger history of the galaxy and the effects of those mergers on their hosts. Such me…
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…
Is NGC 300 a pure exponential disk galaxy?
In Sung Jang, Roelof S. de Jong, I. Minchev +6
NGC 300 is a low-mass disk galaxy in the Sculptor group. In the literature, it has been identified as a pure exponential disk galaxy, as its luminosity profile could be well fitted…
Tracing the anemic stellar halo of M101
In Sung Jang, Roelof S. de Jong, Benne W. Holwerda +3
Models of galaxy formation in a cosmological context predict that massive disk galaxies should have structured extended stellar halos. Recent studies in integrated light, however,…
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…
Stellar Stream and Halo Structure in the Andromeda Galaxy From a Subaru/Hyper Suprime-Cam Survey
Yutaka Komiyama, Masashi Chiba, Mikito Tanaka +13
We present wide and deep photometry of the northwest part of the halo of the Andromeda galaxy (M31) using Hyper Suprime-Cam on the Subaru Telescope. The survey covers 9.2 deg…
