A Possible "Too-Many-Satellites" Problem in the Isolated Dwarf Galaxy DDO 161
Jiaxuan Li, Jenny E. Greene, Shany Danieli +2
The abundance of satellite galaxies provides a direct test of CDM and galaxy formation physics on small scales. While satellites of Milky Way-mass galaxies are well studied, th…
Stellar Mass Calibrations for Local Low-Mass Galaxies
Mithi A. C. de los Reyes, Yasmeen Asali, Risa Wechsler +10
The stellar masses of galaxies are measured using integrated light via several methods -- however, few of these methods were designed for low-mass ($M_{\star}\lesssim10^{8}\rm{M_{\…
The SAGA Survey. V. Modeling Satellite Systems around Milky Way-mass Galaxies with Updated UniverseMachine
Yunchong Wang, Ethan O. Nadler, Yao-Yuan Mao +11
Environment plays a critical role in shaping the assembly of low-mass galaxies. Here, we use the UniverseMachine (UM) galaxy-halo connection framework and the Data Release 3 of the…
ELVES-Dwarf I: Satellites Systems of Eight Isolated Dwarf Galaxies in the Local Volume
Jiaxuan Li, Jenny E. Greene, Shany Danieli +4
The satellite populations of Milky Way--mass systems have been extensively studied, significantly advancing our understanding of galaxy formation and dark matter physics. In contra…
The Morphology of Dwarf Galaxies Hosting Variable Active Galactic Nuclei
Erin Kimbro, Vivienne Baldassare, Guy Worthey +2
We analyze Hubble Space Telescope (HST) optical imaging of eight low-mass galaxies hosting active galactic nuclei (AGN) identified via their photometric variability in \cite{baldas…
Multi-wavelength constraints on the local black hole occupation fraction
Colin J. Burke, Priyamvada Natarajan, Vivienne F. Baldassare +1
The fraction of dwarf galaxies hosting central, intermediate-mass black holes (IMBHs) at low redshifts is an important observational probe of black hole seeding at high redshift. D…
