Kinematics of the Palomar 5 stellar stream from RR Lyrae stars

Adrian M. Price-Whelan, Cecilia Mateu, Giuliano Iorio +3

Thin stellar streams, formed from the tidal disruption of globular clusters, are important gravitational tools, sensitive to both global and small-scale properties of dark matter.…

Variations in the width, density, and direction of the Palomar 5 tidal tails

Ana Bonaca, Sarah Pearson, Adrian M. Price-Whelan +8

Stars that escape globular clusters form tidal tails that are predominantly shaped by the global distribution of mass in the Galaxy, but also preserve a historical record of small-…

A Dwarf Disrupting -- Andromeda XXVII and the North West Stream

Janet Preston, Michelle L. M. Collins, Rodrigo A. Ibata +10

We present a kinematic and spectroscopic analysis of 38 red giant branch stars, in 7 fields, spanning the dwarf spheroidal galaxy Andromeda XXVII and the upper segment of the North…

A Lower Limit on the Mass of Our Galaxy from the H3 Survey

Dennis Zaritsky, Charlie Conroy, Huanian Zhang +5

The timing argument provides a lower limit on the mass of the Milky Way. We find, using a sample of 32 stars at kpc drawn from the H3 Spectroscopic Survey and mock catalog…

Resolving the Metallicity Distribution of the Stellar Halo with the H3 Survey

Charlie Conroy, Rohan P. Naidu, Dennis Zaritsky +4

The Galactic stellar halo is predicted to have formed at least partially from the tidal disruption of accreted dwarf galaxies. This assembly history should be detectable in the orb…

Mapping the Stellar Halo with the H3 Spectroscopic Survey

Charlie Conroy, Ana Bonaca, Phillip Cargile +8

Modern theories of galaxy formation predict that the Galactic stellar halo was hierarchically assembled from the accretion and disruption of smaller systems. This hierarchical asse…
