The Hubble Space Telescope Survey of M31 Satellite Galaxies IV. Survey Overview and Lifetime Star Formation Histories

A. Savino, D. R. Weisz, A. E. Dolphin +35

From orbits of HST imaging, we present deep homogeneous resolved star color-magnitude diagrams that reach the oldest main sequence turnoff and uniformly measured star forma…

One Stream or Two -- Exploring Andromeda's North West Stream

Janet Preston, Denis Erkal, Michelle L. M. Collins +3

We present results of our dynamical stream modelling for the North West Stream in the outer halo of the Andromeda galaxy (M31). Comprising two main segments, the North West Stream…

Properties of the Lower Segment of M31's North West Stream

Janet Preston, Denis Erkal, Michelle L. M. Collins +2

We present a kinematic and spectroscopic analysis of 40 red giant branch stars, in 9 fields, exquisitely delineating the lower segment of the North West Stream (NW-K2), which exten…

A very dark stellar system lost in Virgo: kinematics and metallicity of SECCO1 with MUSE

G. Beccari, M. Bellazzini, L. Magrini +11

We present the results of VLT-MUSE integral field spectroscopy of SECCO1, a faint, star-forming stellar system recently discovered as the stellar counterpart of an Ultra Compact Hi…

Major Substructure in the M31 Outer Halo: the East Cloud

B. McMonigal, N. F. Bate, A. R. Conn +8

We present the first detailed analysis of the East Cloud, a highly disrupted diffuse stellar substructure in the outer halo of M31. The core of the substructure lies at a projected…

HII regions within a compact high velocity cloud. A nearly star-less dwarf galaxy?

M. Bellazzini, L. Magrini, A. Mucciarelli +9

Within the SECCO survey we identified a candidate stellar counterpart to the Ultra Compact High Velocity Cloud (UCHVC) HVC274.68+74.70-123, that was suggested by Adams et al. (2013…
