Black holes in the milky way galaxy. [PDF]
Proc Natl Acad Sci U S A, 1999 Extremely strong observational evidence has recently been found for the presence of black holes orbiting a few relatively normal stars in our Milky Way Galaxy and also at the centers of some galaxies. The former generally have masses of 4–16 times the mass of the sun, whereas the latter are “supermassive black holes” with millions to billions of ...

Milky Way type galaxies in a LCDM cosmology [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 We analyse a sample of 52,000 Milky Way (MW) type galaxies drawn from the publicly available galaxy catalogue of the Millennium Simulation with the aim of studying statistically the differences and similarities of their properties in comparison to our ...

Grand Rotation Curve and Dark-Matter Halo in the Milky Way Galaxy [PDF]
, 2011 A grand rotation curve of the Milky Way Galaxy is constructed, which covers a wide range of radius from the Galactic Center to ~1 Mpc, and is deconvolved into bulge, disk and halo components by least-squares fitting.

The Milky Way Galaxy as a Strong Gravitational Lens [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 We study the gravitational lensing effects of spiral galaxies by taking a model of the Milky Way and computing its lensing properties. The model is composed of a spherical Hernquist bulge, a Miyamoto-Nagai disc and an isothermal halo. As a strong lens, a

The mass of the Milky Way Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 1992 We present a method for determining the Galactic mass and mass distribution based on maximum likelihood parameter estimation. We show that the number density of the Galaxy's outer satellites can be modelled by a power-law function. Assuming that the total distribution of matter (visible and dark) can be modelled in a similar way, we construct a self ...

The star-formation history of the Milky Way Galaxy [PDF]
, 2009 The star-formation histories of the main stellar components of the Milky Way constrain critical aspects of galaxy formation and evolution. I discuss recent determinations of such histories, together with their interpretation in terms of theories of disk ...

An Eclectic View of our Milky Way Galaxy [PDF]
, 2013 The nature of our Milky Way Galaxy is reexamined from an eclectic point of view. Evidence for a central bar, for example, is not reflected in the distribution of RR Lyrae variables in the central bulge [4,5], and it is not clear if either a 2-armed or 4 ...

The Milky Way and the evolution of disk galaxies
, 2002 We present a phenomenological approach to the study of disk galaxy evolution, based on i) a detailed modelling of the Milky Way (used as a prototype disk galaxy) and ii) an extension of the model to other disks through some simple scaling relations, obtained in the framework of Cold Dark matter models.

The Astrophysical Journal, 2023 In the Λ-Cold Dark Matter model of the universe, galaxies form in part through accreting satellite systems. Previous works have built an understanding of the signatures of these processes contained within galactic stellar halos.
