Improved constraints on the Milky Way potential using the M68 stream and DESI spectroscopic data

Carles G. Palau, Wenting Wang, Jiaxin Han +41

We present a selection of stars belonging to the stellar stream of the M68 (NGC 4590) globular cluster, also known as Fjörm. This star selection is an improvement on previous ones…

The Merian Survey: A Statistical Census of Bright Satellites of Milky Way Analogs

Yue Pan, Shany Danieli, Jenny E. Greene +10

We present a statistical census of bright, star-forming satellite galaxies around Milky Way (MW) analogs using the first data release of the Merian Survey. Our sample consists of 3…

Reaching for the Edge II: Stellar Halos out to Large Radii as a Tracer of Dark Matter Halo Mass

Katya Leidig, Benedikt Diemer, Song Huang +3

The diffuse outskirts of brightest cluster galaxies (BCGs) encode valuable information about the assembly history and mass of their host dark matter halos. However, the low surface…

Testing the Stellar Feedback-driven Breathing Mode in Low-mass Galaxies with Gas Kinematics

Yifei Luo, Joseph Wick, Alexie Leauthaud +7

Hydrodynamic simulations have proposed that stellar feedback and bursty star-formation can produce dark matter cores in low-mass galaxies. A key prediction is that feedback-driven…

The Outskirt Stellar Mass of Low-Redshift Massive Galaxies is an Excellent Halo Mass Proxy in Illustris/IllustrisTNG Simulations

Shuo Xu, Song Huang, Alexie Leauthaud +4

Recent observations suggest that the extended stellar halos of low-redshift massive galaxies are tightly connected to the assembly of their dark matter halos. In this paper, we use…

Dwarf Galaxies in the TNG50 Field: connecting their Star-formation Rates with their Environments

Joy Bhattacharyya, Annika H. G. Peter, Alexie Leauthaud

The dwarf galaxies comparable to the LMC and SMC, with stellar masses , are found in a diversity of environments and have long quenching tim…
