M 31, the closest large spiral galaxy to our own, is the best object for studying molecular clouds and their relation to the spiral structure as discussed by the authors, and it is also one of the best places where to estimate molecular clouds masses through the Virial Theorem.Abstract:
M 31, the closest large spiral galaxy to our own, is the best object for studying molecular clouds and their relation to the spiral structure. As one of the astronomical objects with the best known distance (0.78 ± 0.02 Mpc), it is also one of the best places where to estimate molecular clouds masses through the Virial Theorem.read more

Revisiting the Integrated Star Formation Law. Paper I: Non-Starbursting Galaxies.
TL;DR: In this paper, the integrated star formation law was revisited for local quiescent spiral, dwarf, and low-surface-brightness galaxies using new and updated gas and dust-corrected SFR surface densities.

CO map and steep Kennicutt-Schmidt relation in the extended UV disk of M 63
TL;DR: In this paper, deep CO(1−0) and CO(2−1) observations were obtained on the IRAM 30 m telescope along the major axis of the M 63 disk from the center out to the galactocentric radius rgal = 1.6r25 and over a bright UV region at rgal= 1.36r25.

Signatures of the M31-M32 Galactic Collision
TL;DR: In this article, the authors present a self-consistent model of the M31-M32 interaction that simultaneously reproduces observed positions, velocities, and morphologies for both galaxies.

High Resolution IRAS Maps and IR Emission of M31 --- II. Diffuse Component and Interstellar Dust
Cong Xu,George Helou +1 more
TL;DR: In this paper, a radiative transfer model for large-scale dust heating and cooling in the diffuse medium of M31 is studied using the HiRes IRAS maps in conjunction with UV, optical and the HI maps.

A survey of interstellar H I from L-alpha absorption measurements. II
TL;DR: The Copernicus satellite surveyed the spectral region near L alpha to obtain column densities of interstellar HI toward 100 stars as discussed by the authors, and the value of the mean ratio of total neutral hydrogen to color excess was found to equal 5.8 x 10 to the 21st power atoms per (sq cm x mag).

The Milky Way in Molecular Clouds: A New Complete CO Survey
TL;DR: In this article, a large-scale CO survey of the first and second Galactic quadrants and the nearby molecular cloud complexes in Orion and Taurus, obtained with the CfA 1.2 m telescope, was combined with 31 other surveys obtained over the past two decades with that instrument and a similar telescope on Cerro Tololo in Chile, to produce a new composite CO survey.

Linear regression in astronomy. II
TL;DR: A wide variety of least-squares linear regression procedures used in observational astronomy, particularly investigations of the cosmic distance scale, are presented and discussed in this article, where a formula for the intercept offset between two parallel data sets, which propagates slope errors from one regression to the other, and a generalization of the Working-Hotelling confidence bands to nonstandard least squares lines.
Journal ArticleDOI
Determining structure in molecular clouds
TL;DR: In this paper, an automatic, objective routine for analyzing the clumpy structure in a spectral line position-position-velocity data cube is described, which works by first contouring the data at a multiple of the rms noise of the observations, then searching for peaks of emission which locate the clumps, and then following them down to lower intensities.
