Lopsided Galaxies in a cosmological context: a new galaxy-halo connection
Silvio Varela-Lavin, Facundo A. Gómez, Patricia B. Tissera +4
Disc galaxies commonly show asymmetric features in their morphology, such as warps and lopsidedness. These features can provide key information regarding the recent evolution of a…
The Hubble Space Telescope Survey of M31 Satellite Galaxies I. RR Lyrae-based Distances and Refined 3D Geometric Structure
Alessandro Savino, Daniel R. Weisz, Evan D. Skillman +33
We measure homogeneous distances to M31 and 38 associated stellar systems (16.8 6.0), using time-series observations of RR Lyrae stars taken as part of the Hubbl…
Implications of the Milky Way travel velocity for dynamical mass estimates of the Local Group
Katie Chamberlain, Adrian M. Price-Whelan, Gurtina Besla +4
The total mass of the Local Group (LG) is a fundamental quantity that enables interpreting the orbits of its constituent galaxies and placing the LG in a cosmological context. One…
Structural parameters and possible association of the Ultra-Faint Dwarfs Pegasus III and Pisces II from deep Hubble Space Telescope photometry
Hannah Richstein, Ekta Patel, Nitya Kallivayalil +17
We present deep Hubble Space Telescope (HST) photometry of the ultra-faint dwarf (UFD) galaxies Pegasus III (Peg III) and Pisces II (Psc II), two of the most distant satellites in…
The synchronised dance of the Magellanic Clouds' star formation history
P. Massana, T. Ruiz-Lara, N. E. D. Noël +17
We use the SMASH survey to obtain unprecedented deep photometry reaching down to the oldest main sequence turn-offs in the colour-magnitude diagrams (CMDs) of the Small Magellanic…
Kinematical Analysis of Substructure in the Southern Periphery of the Large Magellanic Cloud
Xinlun Cheng, Yumi Choi, Knut Olsen +10
We report the first 3-D kinematical measurements of 88 stars in the direction of several recently discovered substructures in the southern periphery of the Large Magellanic Cloud (…
