We report on the detection of main-sequence stars belonging to the recently identified Canis Major (CMa) galaxy in a field located at ≃4.°2 from the centre of the stellar system. With main-sequence fitting we obtain a distance modulus (m - M) 0 = 14.5 ± 0.3 to the dwarf, corresponding to a distance of D ○. ≃ 8.0 ± 1.2 kpc, in full agreement with previous estimates based on the photometric parallax of M-giants. From the comparison with theoretical isochrones, we constrain the age of the main… Expand
Photometry of a Galactic Field at l = 232°, b = −6°: The Old Open Cluster Auner 1, the Norma-Cygnus Spiral Arm, and the Signature of the Warped Galactic Thick Disk
We perform a detailed photometric study of the stellar populations in a Galactic field at l = 232°, b = -6° in the Canis Major (CMa) constellation. We present the first U, B, V, I photometry of theExpand
Modeling the Stellar Populations in the Canis Major Overdensity: The Relation between the Old and Young Populations
We analyze the stellar populations of the Canis Major stellar overdensity using quantitative color-magnitude diagram (CMD) fitting techniques. The analysis is based on photometry obtained with theExpand
The Closest View of a Dwarf Galaxy: New Evidence on the Nature of the Canis Major Overdensity
We present the first deep color-magnitude diagram of the putative central region (05 × 05) of the Canis Major stellar overdensity (l, b) = (240, - 8) found recently by Martin and coworkers, which hasExpand
Absolute Proper Motion of the Canis Major Dwarf Galaxy Candidate
We have measured the absolute proper motion of the candidate Canis Major dwarf galaxy (CMa), at (l, b) =(240°, -8°). Likely main-sequence stars in CMa have been selected from a region in theExpand
The core of the Canis Major galaxy as traced by red clump stars
The recently discovered stellar system in Canis Major is analysed using He-burning red clump stars as tracers. Canis Major turns out to be the strongest and the most spatially confined overdensity ofExpand
Stellar populations in the Canis Major overdensity
We performed a photometric multicolour survey of the core of the Canis Major overdensity at I ≈ 244°, b ≈ -8°0, reaching V ∼ 22 and covering 0.3 x 1.0 arcmin 2 . The main aim is to unravel theExpand
Detection of a young stellar population in the background of open clusters in the Third Galactic Quadrant (implicancies)
We report the detection of a young stellar population (≤100 Myr) in the background of nine young open clusters belonging to a homogenous sample of 30 star clusters in the third Galactic quadrant (atExpand
Galactic structure in the outer disk: the field in the line of sight to the intermediate-age open cluster Tombaugh 1
We employ optical photometry and high-resolution spectroscopy to study a field toward the open cluster Tombaugh 1, where we identify a complex population mixture, that we describe in terms of youngExpand
A Canis Major Overdensity Imaging Survey. I. Stellar Content and Star-Count Maps: A Distinctly Elongated Body of Main-Sequence Stars
We present the first results from a large-area (~80° × 20°), sparsely sampled, two-filter (B and R) imaging survey toward the Canis Major stellar overdensity, which is claimed to be a disruptingExpand
A radial velocity survey of low Galactic latitude structures – II. The Monoceros Ring behind the Canis Major dwarf galaxy
An AAT/2dF Spectrograph Survey of low Galactic latitudes targeting the putative Canis Major dwarf galaxy and the (possibly) associated tidal debris of stars known as the Monoceros Ring, coveringExpand


The Stellar Population of NGC 5634: A Globular Cluster in the Sagittarius dSph Stream?*
We present the first (V, V-I) color-magnitude diagram (CMD) for the poorly studied globular cluster NGC 5634. The CMD shows a steep red giant branch (RGB) and a predominantly blue horizontal branchExpand
A dwarf galaxy remnant in Canis Major: the fossil of an in-plane accretion on to the Milky Way
An analysis of the asymmetries in the population of Galactic M-giant stars present in the 2MASS All Sky catalogue suggests that the Canis Major dwarf galaxy is a building block of the Galactic thick disk, that the thick disk is continually growing, even up to the present time, and that thick disk globular clusters were accreted onto the Milky Way from dwarf galaxies in co-planar orbits.

Substructure of the outer Galactic halo from the 2-Micron All-Sky Survey
A pole-count analysis of the infrared 2-Micron All-Sky (2MASS) survey is presented, in order to identify faint stream-like great-circle structures within the halo of the Milky Way. Selecting starsExpand
First Detection of the Red Giant Branch Bump in the Sagittarius Dwarf Spheroidal Galaxy
