Bellazzini, M., Ibata, R. A., Chapman, S. C., Mackey, A. D., Monaco, L., Irwin, M. J., ...
We present the results of a thorough study of the nucleus of the Sgr dwarf spheroidal galaxy and of the bright globular cluster M54 that resides within the same nucleus (Sgr,N). We have obtained...
The structural properties and star formation history of Leo T from deep LBT photometry (2008)
Harris, J., Coleman, M. G., Martin, N. F., Bell, E. F., Rix, H-W., ...
We present deep, wide-field g and r photometry of the transition type dwarf galaxy Leo T, obtained with the blue arm of the Large Binocular Telescope. The data confirm the presence of both very young...
Kinematic and Chemical constraints on the formation of M31's inner and outer halo (2007)
Koch, A., Rich, R. M., Reitzel, D. B., Martin, N. F., Ibata, R. A., Chapman, S. C., ...
The halo of M31 shows a wealth of substructures that are consistent with satellite accretion. Here we report on kinematic and abundance results from Keck/DEIMOS spectroscopy in the calcium triplet...
Rix, H-W., Martin, N. F., Zucker, D. B., Dolphin, A. E., Bell, E. F., ...
We have tested the application to Sloan Digital Sky Survey data of the software package MATCH, which fits color-magnitude diagrams (CMDs) to estimate stellar population parameters and distances....
Martin, N. F., Ibata, R. A., Chapman, S. C., Irwin, M., Lewis, G. F.
[abridged] We present the results of a spectroscopic survey of the recently discovered faint Milky Way satellites Boo, UMaI, UMaII and Wil1. Using the DEIMOS spectrograph on Keck, we have obtained...
The Haunted Halos of Andromeda and Triangulum: A panorama of galaxy formation in action (2007)
Ibata, R., Martin, N. F., Irwin, M., Chapman, S., Ferguson, A. M. N., Lewis, G. F., ...
We present a deep photometric survey of M31, conducted with the CFHT and INT, covering the inner 50 kpc of the galaxy, the Southern quadrant out to 150 kpc, and extending to M33. This is the first...
Draco, a flawless dwarf galaxy (2007)
Ségall, M., Ibata, R. A., Irwin, M. J., Martin, N. F., Chapman, S.
The Draco dwarf spheroidal galaxy (dSph), with its apparent immense mass-to-light ratio and compact size, holds many clues to the nature of the enigmatic dark matter. Here we present deep photometric...
Martin, N. F., Ibata, R. A., Chapman, S. C., Irwin, M., Lewis, G. F.
We present the results of a spectroscopic survey of the recently discovered faint Milky Way satellites Boötes, Ursa Major I, Ursa Major II and Willman 1 (Wil1). Using the DEep Imaging Multi-Object...
The haunted halos of Andromeda and Triangulum: a panorama of galaxy formation in action (2007)
Ibata, R., Martin, N. F., Irwin, M., Chapman, S., Ferguson, A. M. N., Lewis, G. F., ...
We present a deep photometric survey of the Andromeda galaxy, conducted with the wide-field cameras of CFHT and INT, that covers the inner 50 kpc of the galaxy and the southern quadrant out to ~150...
Martin, N. F., Ibata, R. A., Irwin, M. J., Chapman, S., Lewis, G. F., Ferguson, A. M. N., ...
We present the discovery of three faint dwarf galaxies and a globular cluster in the halo of the Andromeda galaxy (M31), found in our MegaCam survey that spans the southern quadrant of M31, from a...

As part of our radial velocity survey of low Galactic latitude structures that surround the Galactic disc, we report the detection of the so called Monoceros Ring in the foreground of the Carina...
Martin, N. F., Ibata, R. A., Conn, B. C., Irwin, M. J., Lewis, G. F.
We investigate the role of asymmetries in the line spread function of the 2-degree field spectrograph and the variations in these asymmetries with the CCD, the plate, the time of observation and the...
Martin, N. F., Ibata, R. A., Conn, B. C., Lewis, G. F., Bellazzini, M., Irwin, M. J.
As part of a radial velocity survey of low Galactic latitude structures that we undertook with the 2dF spectrograph on the AAT, we present the radial velocities of more than 1500 Red Giant Branch and...
Martin, N. F., Ibata, R. A., Conn, B. C., Lewis, G. F., Bellazzini, M., Irwin, M. J., ...
In response to criticism by Momany et al. (2004), that the recently-identified Canis Major (CMa) overdensity could be simply explained by the Galactic warp, we present proof of the existence of a...
