Euclid: Early Release Observations -- The extended stellar component of the IC10 dwarf galaxy
F. Annibali, A. M. N. Ferguson, P. M. Sanchez-Alarcon +175
We present a detailed analysis of the old, extended stellar component of the Local Group dwarf galaxy IC 10 using deep resolved-star photometry in the VIS and NISP bands of the Euc…
Tracing Red Giant Members of the Globular Cluster Palomar 5 with APOGEE and Gaia
Allyson A. Sheffield, Sarah Pearson, Lenin F. Nolasco +5
The globular cluster Palomar 5 (Pal 5) is in the process of being tidally shredded as it orbits the Milky Way. Its core is currently at a heliocentric distance of ~21 kpc, near apo…
Streams, Shells, and Substructures in the Accretion-Built Stellar Halo of NGC 300
Catherine E. Fielder, David J. Sand, Michael G. Jones +27
We present deep optical observations of the stellar halo of NGC 300, an LMC-mass galaxy, acquired with the DEEP sub-component of the DECam Local Volume Exploration survey (DELVE) u…
Bar formation and destruction in the FIRE-2 simulations
Sioree Ansar, Sarah Pearson, Robyn E. Sanderson +5
The physical mechanisms responsible for bar formation and destruction in galaxies remain a subject of debate. While we have gained valuable insight into how bars form and evolve fr…
Forecasting the Population of Globular Cluster Streams in Milky Way-type Galaxies
Sarah Pearson, Ana Bonaca, Yingtian Chen +1
Thin stellar streams originating from globular clusters are among the most sensitive tracers of low-mass dark-matter subhalos. Joint analysis of the entire population of stellar st…
