ABSTRACT The Milky Way (MW) remains a primary laboratory for understanding the
structure and evolution of spiral galaxies, but typically we are denied clear views of MW …

Context. Measuring the mass distribution of infrared dark clouds (IRDCs) over the wide
dynamic range of their column densities is a fundamental obstacle in determining the initial …

It has been recently shown that molecular clouds do not exhibit a unique shape for the
column density probability distribution function (N-PDF). Instead, clouds without star …

Here we discuss impacts of distance determinations on the Galactic disk traced by relatively
young objects. The Galactic disk,∼ 40 kpc \sim40~kpc in diameter, is a cross-road of studies …

We map the distribution of dust in M31 at 25 pc resolution using stellar photometry from the
Panchromatic Hubble Andromeda Treasury survey. The map is derived with a new …

We combine new observations from the Hubble Space Telescope's Advanced Camera of
Survey with existing data to investigate the wavelength dependence of near-IR (NIR) …

We analyze the masses and spatial distributions of 14 young stellar groups in Taurus,
Lupus3, ChaI, and IC348. These nearby groups, which typically contain 20–40 members …

Although there is a wealth of column density tracers for both the molecular and diffuse
interstellar medium, there are few observational studies investigating the relationship …

The formation of stars is inextricably linked to the structure of their parental molecular clouds.
Here we take a number of nearby giant molecular clouds (GMCs) and analyse their column …

We are studying the column density distribution of all nearby giant molecular clouds. As part
of this project, we generated several all-sky extinction maps. They are calculated using the …
