How Ought One Parameterize the Milky Way?

چکیده
1. The parameter glut In a well known paper written a quarter century ago, cosmology was described as a search for two numbers (Sandage 1970). As those of you who have attended any of the parallel sessions of Symposium 167 surely appreciate , today's cosmologists nd more than just two numbers interesting. It is likewise clear from the present symposium that the number of interesting parameters associated with the Milky Way is very much greater than two. To illustrate the levels of complexity with which we must deal, I've constructed an incomplete chart of Milky Way structure which is something of a caricature but will still serve to make my point.

In this paper, different definitions of moral conflict and moral dilemma at two levels of recognition and observing moral duties are taken into consideration and some instances of usage of conflict in physiology (conflict of stimulant and goals) and sociology(conflict of roles and norms)are mentioned. Also concepts and constraints used in the moral dilemma, especially the concept of "ought to" ...
متن کاملTidal Imprints Of A Dark Sub-Halo On The Outskirts Of The Milky Way
We present a new analysis of the observed perturbations of the HI disk of the Milky Way to infer the existence of a dark sub-halo that tidally interacted with the Milky Way disk. We examine tidal interactions between perturbing dark sub-halos and the gas disk of the Milky Way using high resolution Smoothed Particle Hydrodynamics (SPH) simulations. We compare our results to the observed HI map o...
متن کاملAre Great Disks Defined by Satellite Galaxies in Milky-Way Type Halos Rare in ΛCDM?
We study the spatial distribution of satellite galaxies by assuming that they follow the dark matter distribution. This assumption is supported by semi-analytical studies based on high-resolution numerical simulations. We find that for a Milky-Way type halo, if only a dozen satellite galaxies are observed, then they can lie on a “great” disk with an rms height of about 40 kpc. The normal to the...
متن کاملThe Milky Way Dark Halo and the Lmc Disk
Stars and their kinematics provide one of the tools available for studies of the shapes of galaxies and their halos. In this review I focus on two specific applications: the shape of the Milky Way dark halo and the shape of the LMC disk. The former is constrained by a variety of observations, but an accurate determination of the axial ratio qDH remains elusive. A very flattened Milky Way dark h...
متن کاملThe Milky Way as a Key to Structural Evolution in Galaxies
Much of our effort in understanding the long-term evolution and morphology of the Milky Way and other galaxies has focused on the equilibrium of its luminous disk. However, the interplay between all components, seen and unseen, is a major cause of observed features and drives evolution. I will review the key underlying dynamics, and in a number of examples, show how this leads to lopsidedness a...
