The outermost stellar halo of NGC 5128 (Centaurus A): Radial structure
M. Rejkuba, W. E. Harris, L. Greggio +2
The extended stellar halos of galaxies contain important clues for investigating their assembly history and evolution. We investigate the resolved stellar content and the extended…
Multi-scale feedback and feeding in the closest radio galaxy Centaurus A
B. McKinley, S. J. Tingay, M. Gaspari +12
Supermassive black holes and supernovae explosions at the centres of active galaxies power cycles of outflowing and inflowing gas that affect galactic evolution and the overall str…
AGC 226178 and NGVS 3543: Two deceptive dwarfs towards Virgo
Michael G. Jones, David J. Sand, Michele Bellazzini +21
The two sources AGC 226178 and NGVS 3543, an extremely faint, clumpy, blue stellar system and a low surface brightness dwarf spheroidal, are adjacent systems in the direction of th…
Hubble Space Telescope Observations of NGC 253 Dwarf Satellites: Discovery of Three Ultra-faint Dwarf Galaxies
Burçin Mutlu-Pakdil, David J. Sand, Denija Crnojević +8
We present deep Hubble Space Telescope imaging of five faint dwarf galaxies associated with the nearby spiral NGC 253 (D3.5 Mpc). Three of these are newly discovered ultra…
Resolved Dwarf Galaxy Searches within ~5 Mpc with the Vera Rubin Observatory and Subaru Hyper Suprime-Cam
Burçin Mutlu-Pakdil, David J. Sand, Denija Crnojević +7
We present a preview of the faint dwarf galaxy discoveries that will be possible with the Vera C. Rubin Observatory and Subaru Hyper Suprime-Cam in the next decade. In this work, w…
Satellites Around Milky Way Analogs: Tension in the Number and Fraction of Quiescent Satellites Seen in Observations Versus Simulations
Ananthan Karunakaran, Kristine Spekkens, Kyle A. Oman +13
We compare the star-forming properties of satellites around Milky Way (MW) analogs from the Stage~II release of the Satellites Around Galactic Analogs Survey (SAGA-II) to those fro…
