Changes Of Dust Opacity With Density in the Orion A Molecular Cloud

Arabindo Roy, Peter G. Martin, Danae Polychroni +12

We have studied the opacity of dust grains at submillimeter wavelengths by estimating the optical depth from imaging at 160, 250, 350, and 500 um from the Herschel Gould Belt Surve…

Recent star formation in the Lupus clouds as seen by Herschel

K. L. J. Rygl, M. Benedettini, E. Schisano +26

We present a study of the star formation histories of the Lupus I, III, and IV clouds using the Herschel 70-500 micron maps obtained by the Herschel Gould Belt Survey Key Project.…

OB Associations at the Upper End of the Milky Way Luminosity Function

Mubdi Rahman, Christopher D. Matzner, Dae-Sik Moon

The Milky Way's most luminous, young and massive (M > 10^4 Msun) star clusters and OB associations have largely evaded detection despite knowledge of their surrounding H II regions…

Relativity and the evolution of the Galactic center S-star orbits

Fabio Antonini, David Merritt

We consider the orbital evolution of the S-stars, the young main-sequence stars near the supermassive black hole (SBH) at the Galactic center (GC), and put constraints on competing…

Spinning Dust Emission from Wobbling Grains: Important Physical Effects and Implications

Thiem Hoang, A. Lazarian

We review major progress on the modeling of electric dipole emission from rapidly spinning tiny dust grains, including polycyclic aromatic hydrocarbons (PAHs). We begin by summariz…

The Protocluster G18.67+0.03: A Test Case for Class I Methanol Masers as Evolutionary Indicators for Massive Star Formation

C. J. Cyganowski, C. L. Brogan, T. R. Hunter +4

We present high angular resolution Submillimeter Array (SMA) and Karl G. Jansky Very Large Array (VLA) observations of the massive protocluster G18.67+0.03. Previously targeted in…
