The remnants of galaxy formation from a panoramic survey of the region around M31 (2009)
McConnachie, Alan W., Irwin, Michael J., Ibata, Rodrigo A., Dubinski, John, Widrow, Lawrence M., Martin, Nicolas F., ...
In hierarchical cosmological models, galaxies grow in mass through the continual accretion of smaller ones. The tidal disruption of these systems is expected to result in loosely bound stars...
Martin, Nicolas F., McConnachie, Alan W., Irwin, Mike, Widrow, Lawrence M., Ferguson, Annette M. N., Ibata, Rodrigo A., ...
We present the discovery of two new dwarf galaxies, Andromeda XXI and Andromeda XXII, located in the surroundings of the Andromeda and Triangulum galaxies (M31 and M33). These discoveries stem from...
Inferring the dynamics of stellar streams via distance gradients (2009)
Jin, Shoko, Martin, Nicolas F.
We present a simple result in which the distance gradient along a stream can be used to derive the transverse velocity (i.e. proper motion) along it, if the line-of-sight velocity is also known. We...
The Signature of Galactic Tides in Local Group Dwarf Spheroidals (2008)
Penarrubia, Jorge, Navarro, Julio F., McConnachie, Alan W., Martin, Nicolas F.
(Abridged) We use N-body simulations to explore the effects of tidal stripping on the structure of dwarf spheroidal galaxies (dSphs). We model dSphs as King spheres embedded in NFW dark halos that...
Conn, Blair C., Lane, Richard R., Lewis, Geraint F., Irwin, Mike J., Ibata, Rodrigo A., Martin, Nicolas F., ...
This paper concludes a systematic search for evidence of the Monoceros Ring and Canis Major dwarf galaxy around the Galactic Plane. Presented here are the results for the Galactic longitude range of...
Martin, Nicolas F., Rix, Hans-Walter
We derive the structural parameters of the recently discovered very low luminosity Milky Way satellites through a Maximum Likelihood algorithm applied to SDSS data. For each satellite, even when only...
A deep large binocular telescope view of the Canes Venatici I dwarf galaxy (2008)
Martin, Nicolas F., Coleman, Matthew G., Rix, Hans-Walter, Bell, Eric F., Sand, David J., ...
A trio of new local group galaxies with extreme properties (2008)
McConnachie, Alan W., Huxor, Avon, Martin, Nicolas F., Irwin, Mike J., Chapman, Scott C., Fahlman, Gregory, ...
We report on the discovery of three new dwarf galaxies in the Local Group. These galaxies are found in new CFHT/MegaPrime g,i imaging of the southwestern quadrant of M31, extending our extant survey...
A deep Large Binocular Telescope view of the Canes Venatici I dwarf galaxy (2008)
Martin, Nicolas F., Coleman, Matthew G., Rix, Hans-Walter, Bell, Eric F., Sand, David J., ...
We present the first deep color-magnitude diagram of the Canes Venatici I (CVn I) dwarf galaxy from observations with the wide-field Large Binocular Camera on the Large Binocular Telescope. Reaching...

Kinematic and chemical constraints on the formation of M31's inner and outer halo (2008)
Koch, Andreas, Rich, R. Michael, Reitzel, David B., Martin, Nicolas F., Ibata, Rodrigo A., Chapman, Scott C., ...
The halo of M31 shows a wealth of substructures, some of which are consistent with assembly from satellite accretion. Here we report on kinematic and abundance results from Keck DEIMOS spectroscopy...
A deep Large Binocular Telescope view of the Canes Venatici I dwarf galaxy (2007)
Martin, Nicolas F., Coleman, Matthew G., Rix, Hans-Walter, Bell, Eric F., Sand, David J., ...
We present the first deep color-magnitude diagram of the Canes Venatici I (CVnI) dwarf galaxy from observations with the wide field Large Binocular Camera on the Large Binocular Telescope. Reaching...
The Elongated Structure of the Hercules dSph from Deep LBT Imaging (2007)
Coleman, Matthew G., Martin, Nicolas F., Rix, Hans-Walter, Sand, David J., Bell, Eric F., ...
We present a deep, wide-field photometric survey of the newly-discovered Hercules dwarf spheroidal galaxy, based on data from the Large Binocular Telescope. Images in B, V and r were obtained with...
Galactic halo stellar structures in the Triangulum-Andromeda region (2007)
Martin, Nicolas F., Ibata, Rodrigo A., Irwin, Mike
This letter reports on the Galactic stellar structures that appear in the foreground of our Canada-France-Hawaii-Telecopse/MegaCam survey of the halo of the Andromeda galaxy. We recover the main...
Conn, Blair C., Lane, Richard R., Lewis, Geraint F., Gil-Merino, Rodrigo, Irwin, Mike J., Ibata, Rodrigo A., ...
We present the results of an AAT wide-field camera survey of the stars in the Monoceros Ring and purported Canis Major overdensity in the Galactic longitudes of {\it l} = (193 - 276)$^\circ$. Current...
