Morphologies of High Redshift, Dust Obscured Galaxies from Keck Laser Guide Star Adaptive Optics
J. Melbourne, V. Desai, Lee Armus +7
Spitzer MIPS images in the Bootes field of the NOAO Deep Wide-Field Survey have revealed a class of extremely dust obscured galaxy (DOG) at z~2. The DOGs are defined by very red op…
The opaque nascent starburst in NGC 1377: Spitzer SINGS observations
H. Roussel, G. Helou, J. D. Smith +16
We analyze extensive data on NGC1377 from the Spitzer Infrared Nearby Galaxies Survey (SINGS). Within the category of nascent starbursts, that we previously selected by their infra…
Fast Diffusion Mechanism of Silicon Tri-interstitial Defects
Yaojun A. Du, Stephen A. Barr, Kaden R. A. Hazzard +3
We reveal the microscopic self-diffusion process of compact tri-interstitials in silicon using a combination of molecular dynamics and nudged elastic band methods. We find that the…
Stellar populations associated with the LMC Papillon Nebula
F. Meynadier, M. Heydari-Malayeri, L. Deharveng +5
We study the Large Magellanic Cloud Papillon Nebula (N159-5), a conspicuous High Excitation Blob (HEB) lying in the star forming complex N159. Using JHK near-infrared photometry ob…
Warm dust and aromatic bands as quantitative probes of star-formation activity
N. M. Forster Schreiber, H. Roussel, M. Sauvage +1
We combine samples of spiral galaxies and starburst systems observed with ISOCAM to investigate the reliability of mid-infrared (MIR) dust emission as a quantitative tracer of star…
NLTE Spectral Analysis of Central Stars of PNe Interacting with the ISM
T. Rauch, F. Kerber, E. Furlan +1
The analysis of Planetary Nebulae (PNe) provides a tool to investigate the properties of their exciting central stars (CSPN) at the moment of the PN ejection as well as on the prop…
