Discovery, Characterization, and Potential Origins of a Stream in the Stellar Halo of Nearby LMC-Mass Galaxy NGC 55

Benjamin N. Velguth, Burçin Mutlu-Pakdil, Erik Tollerud +31

We present a previously undetected stellar stream in the halo of the LMC-mass dwarf galaxy NGC 55 (2 Mpc), as part of an ongoing effort to characterize the stellar halos of LMC/SMC…

From observing strategies to velocity dispersion bias: forward modeling unresolved binaries in ultra-faint dwarf galaxies

Xiaowei Ou, Andrew B. Pace, Nitya Kallivayalil +9

Ultra-faint dwarf galaxies (UFDs) in the Milky Way are ideal probes of low-mass galaxy formation and dark matter because they are highly dark-matter dominated. In the lowest-mass s…

Constraining the shape of dark matter haloes using only starlight II. Tests of the technique with objects of known gravitational potential

Jorge Sanchez Almeida, Angel R. Plastino, Sergio Guerra Arencibia +2

Under the collisionless cold dark matter (CDM) paradigm, galaxies with stellar masses below 10**(5-6) Msun are expected to preserve primordial cuspy dark matter (DM) profiles. Beca…

Reconstructing the orbits of Milky Way dwarf galaxies: A Large Magellanic Cloud perspective

Alberto Manuel Martínez-García, Andrés del Pino, Roeland P. van der Marel +14

The orbital histories of the dwarf satellites of the Milky Way (MW) are key to understanding their evolution and placing their present-day properties in a dynamical context. We pre…

Probing the IMF in the Early Universe -- Direct measurements in the Boötes I UFD with JWST/NIRCam

Keyi Ding, Mario Gennaro, Roberto J. Avila +20

The dependence of the stellar initial mass function (IMF) on star-formation environment, particularly at low metallicities and high redshifts, remains poorly constrained. Ultra-fai…
