We present a preliminary study of using the template of an ensemble of evolving shells we developed for M 82 (Yao 2009). we apply the model to represent various stages of starburst evolution in a well known sample of nearby luminous infrared galaxies (LIRGs). In this way, we attempt to interpret the relationship between the degree of molecular excitation and ratio of far-infrared (FIR) to CO lu...

There are two existing avenues to interpreting the diffuse ISM: the theorist’s approach in which real data is interpreted numerically in the context of simulations, and the observer’s approach in which objects are found and categorized by eye. We are pioneering a middle way, following the fast-growing science of machine vision to extract shape information from complex maps of the diffuse Galact...

Aliphatic hydrocarbons exhibit an absorption feature at 3.4 m, observed toward sources that sample diffuse regions of the interstellar medium (ISM). The absorbers responsible for this feature are assumed to reside in some component of interstellar dust, but the physical nature of the particles (size, shape, structure, etc.) is uncertain. Observations of interstellar polarization provide discrim...

We present optical observations and 2D hydrodynamic modeling of an isolated shocked ISM cloud. Hα images taken in 1992.6 and 2003.7 of a small optical emission cloud along the southwestern limb of the Cygnus Loop were used to measure positional displacements of ∼ 0. 1 yr for surrounding Balmer dominated emission filaments and 0. 025 − . 055 yr for internal cloud emission features. These measure...

The heliosphere serves as a probe of interstellar material (ISM) close to the Sun. Measurements of ISM inside and outside of the heliosphere show that we reside in typical warm partially ionized ISM that can be successfully modeled using equilibrium photoionization models. The heliosphere wake leaves a ∼ 200× 1000 AU trail in space of low density, n < 0.05 cm, cooling plasma comingled with ISM....

Arcsecond-resolution spectral observations toward the protobinary system IRAS 16293-2422 at 344 and 354 GHz were conducted using the Submillimeter Array. Complex organic molecules such as CH3OH and HCOOCH3 were detected. Together with the rich organic inventory revealed, it clearly indicates the existence of two, rather than one, compact hot molecular cores (. 400 AU in radius) associated with ...
