TLDR
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

First Resolved Dust Continuum Measurements of Individual Giant Molecular Clouds in the Andromeda Galaxy
TL;DR: In this article, the authors used the wideband upgrade of the Submillimeter Array (SMA) at 230 GHz to obtain the first continuum detections of the thermal dust emission on sub-GMC scales within the Andromeda galaxy (M31).
Journal ArticleDOI
Disk thickness and spiral arm structure of M31
TL;DR: In this paper, the authors obtained the disk thickness and spiral arm structure of M31 by fitting a two-armed (a-and b-arm) spiral structure by logarithmical spirals.

Large-scale Hydrodynamical Shocks as the Smoking-gun Evidence for a Bar in M31
TL;DR: In this paper , the authors identify sharp velocity jump features with a typical amplitude over 100 km s−1 in the central region of M31 (4.6 kpc × 2.3 kpc, or 20′×10′ ).
Journal ArticleDOI
Particularly Efficient Star Formation in M33
TL;DR: In this paper, the authors used the HERA heterodyne array on the IRAM 30 m telescope to detect the molecular gas in M 33, a small Local Group spiral at a distance of 840 kpc which shares many of the characteristics of the intermediate redshift galaxies.

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.
