The internal structure of Cold Dark Matter Haloes [PDF]

, 2010
Currently favoured cosmological models for structure formation of the Universe assume that a large fraction of the mass of the Universe is 'dark'. The evidence for dark matter comes from observations of its gravitational influence.

3D CMZ. IV. Distinguishing Near versus Far Distances in the Galactic Center Using Spitzer and Herschel

The Astrophysical Journal
A comprehensive 3D model of the central 300 pc of the Milky Way, the Central Molecular Zone (CMZ) is of fundamental importance in understanding energy cycles in galactic nuclei, since the 3D structure influences the location and intensity of star ...

Supersonic waves of magnetization in dark interstellar molecular clouds

, 2017
We suggest that supersonic linewidths inferred from recent measurements of magnetic fields toward the core position in dark interstellar molecular clouds may be due to transverse waves of magnetization propagating in a poorly ionized, magnetically ...

The collective origin of spiral structures in disk galaxies

EPJ Web of Conferences, 2012
After almost fifty years the origin of spiral arms in disk galaxies remains one of the major unsolved problems in astrophysics. Recent attempts have indicated that substructures in the dark matter halos of galaxies could induce spiral patterns in disks ...

Interplay of Magnetic Fields, Dust Extinction, and Grain Alignment in Three Molecular Clouds

The Astrophysical Journal
We present a multiwavelength study of three molecular clouds, L1346, L1388, and L1598, combining R -band polarimetric and archival photometric data to investigate their magnetic field morphology, physical characteristics, and dust grain alignment ...

Modeling Complex Organic Molecules’ Formation in Cold Cores: Multiphase Models with Nonthermal Mechanisms

The Astrophysical Journal Supplement Series
In recent years, a significant number of oxygen-bearing complex organic molecules (COMs) have been detected in the gas phase of cold dark clouds such as TMC-1.

Notes Toward a Meteorology of the Cloud

Surveillance & Society, 2015
The premise of detailed forecasts is meteorological observation. An ominous cloud has eclipsed the global horizon of neoliberal capitalist realism. Researching cloud formations, I queried Google with the search term “clouds.” However, when using the term

Magnetomechanical supersonic waves in dark molecular clouds

, 2017
We propose and investigate the magnetoelastodynamic mechanism of the wave motions of poorly ionized superparamagnetic gas-dust interstellar medium capable of sustaining long-ranged magnetization.

The Molecular Inventory of TMC-1 with GOTHAM Observations

The Astrophysical Journal Supplement Series
Spectral line surveys of the Taurus Molecular Cloud-1 (TMC-1) have led to the detection of more than 100 new molecular species, making it the most prolific source of interstellar molecular discoveries.

Feeding vs Falling. The growth and collapse of molecular clouds in a turbulent interstellar medium

, 2017
In order to understand the origin of observed molecular cloud properties, it is critical to understand how clouds interact with their environments during their formation, growth and collapse.
