CHORD HI-Galaxy Survey Forecasts: Searching for nearby dark galaxies and high redshift giants
Akanksha Bij, Kristine Spekkens, Hans S. Hopkins +6
Population studies of gas-rich galaxies across the full range of Neutral Hydrogen (HI) masses that galaxies are known to exhibit ($10^5 \lesssim M_{\mathrm{HI}} \lesssim 10^{11} M_…
Tracing satellite planes in the Sculptor group: II. Discovery of five faint dwarf galaxies in the DESI Legacy Survey
David Martinez-Delgado, Michael Stein, Marcel S. Pawlowski +5
Although substantial progress has been made in reconciling LCDM simulations with the observed abundance and distribution of satellite galaxies, important tensions persist. Studying…
STRRINGS: STReams in Residual Images of Nearby GalaxieS
E. Sola, D. Chemaly, V. Belokurov +11
Tidal features from galaxy mergers, particularly stellar streams, offer valuable insights into galaxy assembly and dark matter halo properties. This paper aims to identify a large…
A Pearl in the Shell: an ultra-compact dwarf within the tidal debris surrounding spiral galaxy NGC 7531
David MartÃnez-Delgado, Aaron J. Romanowsky, Yimeng Tang +7
Stellar substructures within tidal debris preserve information about their progenitor galaxies' properties, offering insights into hierarchical mass assembly. We examine a compact…
