Are dSph galaxies Galactic building blocks?

EPJ Web of Conferences, 2012
Dwarf spheroidal galaxies (dSph) are frequently assumed to represent surviving examples of a vast now destroyed population of small systems in which many of the stars now forming the Milky Way were formed. Ongoing accretion and considerable sub-structure

The Rapid Formation of the Metal-poor Milky Way

The Astrophysical Journal
Our understanding of the assembly timeline of the Milky Way has been transforming along with the dramatic increase in astrometric and spectroscopic data available over the past several years.

MOND's Problem in Local Group [PDF]

arXiv, 2011
I use the distances and motions of Local Group galaxies to test Modified Newtonian Dynamics (MOND). The old Local Group timing argument of Kahn & Woltjer, which assumed Newtonian gravity and a simple radial orbit, indicated that the total mass of M31 and the Milky Way far exceeds their known baryonic mass.

The size of the Milky Way galaxy

The size of a galaxy is one of the fundamental parameters that reflects its growth and assembly history. Traditionally, the size of the Milky Way has been characterized by the scale length of the disk, based on the assumption of an exponential density profile. Earlier scale length measurements suggest the Milky Way is an overly compact galaxy, compared

In Pursuit of the Least Luminous Galaxies

Advances in Astronomy, 2010
The dwarf galaxy companions to the Milky Way are unique cosmological laboratories. With luminosities as low as 10−7LMW, they inhabit the lowest mass dark matter halos known to host stars and are presently the most direct tracers of the distribution, mass

Terraforming the Milky Way galaxy (Extended)

, 2023
The concept of terraforming the entire Milky Way galaxy within a timeframe of 400,000 to 1 million years, as proposed by NAR (Ndoni Advanced Robotics), presents several theoretical and speculative challenges, spanning immense timeframes and involving technologies far beyond our current understanding.

Comment on: Protecting Life in the Milky Way: Metals Keep the GRBs Away by Stanek et al [PDF]

arXiv, 2006
Stanek et al. (astro-ph/0604113) have noted that the four low-redshift long-duration gamma-ray bursts (LSB) observed to date all occurred in faint, metal-poor galaxies. Given this selection, they argue that it is improbable that there has been a substantial population of Milky Way galaxy bursts sufficiently recently to affect life on Earth.
