The impact of disc disruption on Milky Way satellite counts

Mark R. Lovell, Alexander H. Riley, Isabel Santos-Santos

Estimates for the total number of Milky Way (MW) satellites are often generated from a combination of the observed number of satellites in surveys, adjustments for the completeness…

Implications of a contracted dark matter halo for the Milky Way's inferred virial mass

Diego Dado, Shaun T. Brown, Azadeh Fattahi +2

We investigate how reliably the global properties of Milky Way-mass dark matter haloes can be recovered from dynamical data over a limited radial range, particularly $\lesssim 30~\…

Sub-millimeter galaxies in hierarchical models: revisiting the need for a top-heavy stellar initial mass function with Bayesian optimisation

Edward Elliott, C. M. Baugh, Cedric Lacey

The properties of high-redshift sub-millimetre galaxies (SMGs) remain controversial within hierarchical structure formation models. We revisit whether a top-heavy stellar initial m…

Multi-resolution kinematic modelling of nearby galaxies: a demonstration using MHONGOOSE observations

B. R. Makinson, K. A. Oman, A. M. Swinbank

We present a novel method of combining kinematic models obtained at multiple spatial resolution levels in a self-consistent manner. The MHONGOOSE survey has mapped atomic hydrogen…

The Cocytos Stream: A Disrupted Globular Cluster from our Last Major Merger?

Christian Aganze, Vedant Chandra, Risa H. Wechsler +48

The census of stellar streams and dwarf galaxies in the Milky Way provides direct constraints on galaxy formation models and the nature of dark matter. The DESI Milky Way survey --…

The DESI Y1 RR Lyrae catalog I: Empirical modeling of the cyclic variation of spectroscopic properties and a chemodynamical analysis of the outer halo

Gustavo E. Medina, Ting S. Li, Sergey E. Koposov +44

We present the catalog of RR Lyrae stars (RRLs) observed in the first year of operations of the Dark Energy Spectroscopic Instrument (DESI) survey. This catalog contains 6,240 RRLs…
