Mid-Infrared Spectral Diagnostics of Luminous Infrared Galaxies
A. O. Petric, L. Armus, J. Howell +22
We present a statistical analysis of the mid-infrared (MIR) spectra of 248 luminous infrared (IR) galaxies (LIRGs) which comprise the Great Observatories All-sky LIRG Survey (GOALS…
The 9.7 and 18 um silicate absorption profiles towards diffuse and molecular cloud lines-of-sight
J. M. van Breemen, M. Min, J. E. Chiar +8
Studying the composition of dust in the interstellar medium (ISM) is crucial in understanding the cycle of dust in our galaxy. The mid-infrared spectral signature of amorphous sili…
On the nature and evolution of the unique binary pulsar J1903+0327
P. C. C. Freire, C. G. Bassa, N. Wex +16
(abridged) PSR J1903+0327, a millisecond pulsar in an eccentric (e = 0.44) 95-day orbit with a (~ 1Msun) companion poses a challenge to our understanding of stellar evolution in bi…
Dust at sub-solar metallicity: the case of post-AGB stars in the Large Magellanic Cloud
M. Matsuura, G. C. Sloan, J. Bernard-Salas +2
Low- and intermediate-mass stars are one of the important dust sources in the interstellar medium (ISM) of galaxies. The compositions of dust ejected from these stars are likely to…
The SAGE-Spec Spitzer Legacy program: The life-cycle of dust and gas in the Large Magellanic Cloud. Point source classification I
Paul M. Woods, J. M. Oliveira, F. Kemper +55
We present the classification of 197 point sources observed with the Infrared Spectrograph in the SAGE-Spec Legacy program on the Spitzer Space Telescope. We introduce a decision-t…
Mapping the Galactic Halo with blue horizontal branch stars from the 2dF quasar redshift survey
Roberto De Propris, Craig D. Harrison, Peter J. Mares +2
We use 666 blue horizontal branch (BHB) stars from the 2Qz redshift survey to map the Galactic halo in four dimensions (position, distance and velocity). We find that the halo exte…
Spitzer Spectroscopy of Mass Loss and Dust Production by Evolved Stars in Globular Clusters
G. C. Sloan, N. Matsunaga, M. Matsuura +7
We have observed a sample of 35 long-period variables and four Cepheid variables in the vicinity of 23 Galactic globular clusters using the Infrared Spectrograph on the Spitzer Spa…
Planetary nebulae abundances and stellar evolution II
S. R. Pottasch, J. Bernard-Salas
Context: In recent years mid- and far infrared spectra of planetary nebulae have been analysed and lead to more accurate abundances. It may be expected that these better abundances…
Black hole accretion and star formation as drivers of gas excitation and chemistry in Mrk231
P. P. Van der Werf, K. G. Isaak, R. Meijerink +34
We present a full high resolution SPIRE FTS spectrum of the nearby ultraluminous infrared galaxy Mrk231. In total 25 lines are detected, including CO J=5-4 through J=13-12, 7 rotat…
Complex Molecule Formation in Grain Mantles
P. Hall, T. J. Millar
Context: Complex molecules such as ethanol and dimethyl ether have been observed in a number of hot molecular cores and hot corinos. Attempts to model the molecular formation proce…
Large-Scale Outflows from AGN: a link between central black holes and galaxies
Daniel Proga, Ryuichi Kurosawa, Kentaro Nagamine
We summarize the results from numerical simulations of mass outflows from AGN. We focus on simulations of outflows driven by radiation from large-scale inflows. We discuss the prop…
Outflows from AGN: their Impact on Spectra and the Environment
Daniel Proga, Ryuichi Kurosawa
We present a brief summary of the main results from our multi-dimensional, time-dependent simulations of gas dynamics in AGN. We focus on two types of outflows powered by radiation…
A Spitzer Space Telescope far-infrared spectral atlas of compact sources in the Magellanic Clouds. II. The Small Magellanic Cloud
Jacco Th. van Loon, Joana M. Oliveira, Karl D. Gordon +2
We present 52-93 micron spectra, obtained with the Spitzer Space Telescope, of luminous compact far-IR sources in the SMC. These comprise 9 Young Stellar Objects (YSOs), the compac…
A Universal Stellar Initial Mass Function? A Critical Look at Variations
Nate Bastian, Kevin R. Covey, Michael R. Meyer
Few topics in astronomy initiate such vigorous discussion as whether or not the initial mass function (IMF) of stars is universal, or instead sensitive to the initial conditions of…
