PLANETARY NEBULAE IN THE INNER MILKY WAY II: THE BULGE-DISK TRANSITION
(UNIV NACIONAL AUTONOMA MEXICO, INST DE ASTRONOMIA, 2011)
In this work, a sample of planetary nebulae located in the inner-disk and bulge of the Galaxy is used in order to find the galactocentric distance which better separates these two populations, from the point of view of ...
Planetary nebulae and determination of the bulge-disk boundary
(International Astronomical UnionBeijing, 2012)
In this paper, a sample of planetary nebulae in the Galaxy's inner-disk and bulge is used to find the galactocentric distance that optimally separates these two populations in terms of their abundances. Statistical distance ...

Discovery of Thousands of RR Lyrae by the Catalina Surveys
(2013)
We have performed an extensive search for RR Lyrae among the 500 million sources observed by the Catalina Surveys. We detect 23,000 type-ab RR Lyrae (of which 18,700 are new discoveries) from a region spanning 3/4 of the ...
No Evidence for a Dark Matter Disk Within 4 kpc From The Galactic Plane
(2010)
We estimated the dynamical surface mass density (Sigma) at the solar Galactocentric distance between 2 and 4 kpc from the Galactic plane, as inferred from the observed kinematics of the thick disk. We find Sigma(z=2 ...
Testing modified gravity theory in the Milky Way TESTING MODIFIED GRAVITY THEORY in the MILKY WAY NEGRELLI et al.
(2018-01-01)
We perform a test of John Moffat's modified gravity theory (MOG) within the Milky Way, adopting the well-known rotation curve method. We use the dynamics of observed tracers within the disk to determine the gravitational ...
The Globular Cluster System of the Low-Luminosity Elliptical Galaxy NGC 1427
(IOP Publishing, 2001-12)
Washington photometry is presented for a large number of globular cluster candidates associated with the low-luminosity elliptical galaxy NGC 1427 in the Fornax cluster. The survey is mostly complete to T1 = 23.5 (V ≈ 24.0) ...
