Cosmic ray secondary nuclei and the structure of the galaxy [PDF]

The consequencies of diffusive acceleration of cosmic rays in supernova shocks propagation through an inhomogeneous interstellar medium are explored. The acceleration takes place in the hot, tenuous, intercloud gas, while nuclear collisions, leading to ...

Modeling the Far-infrared Polarization Spectrum of a High-mass Star-forming Cloud

The Astrophysical Journal
The polarization spectrum, or wavelength dependence of the polarization fraction, of interstellar dust emission provides important insights into the grain alignment mechanism of interstellar dust grains.

Playing with FIRE: A Galactic Feedback-halting Experiment Challenges Star Formation Rate Theories

The Astrophysical Journal
Stellar feedback influences the star formation rate (SFR) and the interstellar medium of galaxies in ways that are difficult to quantify numerically, because feedback is an essential ingredient of realistic simulations.

Interstellar Detection of O-protonated Carbonyl Sulfide, HOCS+

The Astrophysical Journal
We present the first detection in space of O-protonated carbonyl sulfide (HOCS ^+ ), in the midst of an ultradeep molecular line survey toward the G+0.693-0.027 molecular cloud. From the observation of all K _a = 0 transitions ranging from J _lo = 2 to J
