Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons, or PAHs. Since the 1980s, evidence has indicated that these molecules are abund...
Galaxy cluster formation from the large-scale structure: a case study of the Abell 2125 complex at z=0.247
C153 SW cD
2014/12/24
The structure of the universe is believed to have formed by clustering hierarchically from small to large scales. Much of this evolution occurs very slowly but at a few special times more rapid, viole...
X-Raying A2125: A Large-Scale Hierarchical Complex of Galaxies and Hot Gas
Abell 2125 X-rays
2014/12/24
We present an 82 ks Chandra ACIS-I observation of a large-scale hierarchical complex, which consists of various clusters/groups of galaxies and low surface brightness X-ray emission at z = 0.247. This...
We have used new and archival infrared and radio observations to search for a dwarf galaxy associated with the high-velocity cloud (HVC) known as `complex H.' Complex H is a large (Ω gtrsim 400 deg2) ...
We present new images and photometry of the massive star-forming complex Cygnus X obtained with the Infrared Array Camera (IRAC) and the Multiband Imaging Photometer for Spitzer (MIPS) on board the Sp...
Title: Properties of the Compact HII Region Complex G-0.02-0.07
extinction maps high-resolution
2014/12/20
Abstract: We present new extinction maps and high-resolution Paschen alpha images of G-0.02-0.07, a complex of compact HII regions located adjacent to the M-0.02-0.07 giant molecular cloud, 6 parsecs ...
Anatomy of the Gem OB1 molecular cloud complex
Gem Molecular cloud Molecular gas Form Star formation
2014/12/9
I have conducted an extensive study of the Gem OB1 molecular cloud complex in order to determine the global morphology of the molecular gas and how the morphology is correlated with the distribution o...
Complex molecules toward low-mass protostars: the Serpens core
Complex molecules low-mass protostars Serpens core
2011/10/20
Gas-phase complex organic molecules are commonly detected toward high-mass protostellar hot cores. Detections toward low-mass protostars and outflows are comparatively rare, and a larger sample is key...
Complex Radio Spectral Energy Distributions in Luminous and Ultraluminous Infrared Galaxies
Complex Radio Spectral Energy Distributions Luminous Ultraluminous Infrared
2011/10/12
We use the Expanded Very Large Array to image radio continuum emission from local luminous and ultraluminous infrared galaxies (LIRGs and ULIRGs) in 1 GHz windows centered at 4.7, 7.2, 29, and 36 GHz....
The high-velocity cloud complex Galactic Center Negative as seen by EBHIS and GASS. I. Cloud catalog and global properties
ISM: clouds – Galaxy: halo
2011/10/10
Using Milky Way data of the new Effelsberg-Bonn HI Survey (EBHIS) and the Galactic All-Sky Survey (GASS), we present a revised picture of the high-velocity cloud (HVC) complex Galactic Center Negative...
Dissecting high-mass star-forming regions; tracing back their complex formation history
Dissecting high-mass star-forming regions complex formation history
2011/8/24
We present near-infrared JHKs imaging as well as K-band multi-object spectroscopy of the massive stellar content of W3 Main using LUCI at the LBT. We confirm 13 OB stars by their absorption line spect...

The extraordinary complex magnetic field the helium-strong star HD 37776
2011/1/11
The early-type chemically peculiar stars often show strong magnetic fields on their surfaces. These magnetic topologies are organized on large scales and are believed to be close to an oblique dipole ...

Chandra Observation the Obscured Star-Forming Complex W40
2011/1/11
The young stellar cluster illuminating the W40 H II region, one of the nearest massive star forming regions, has been observed with the ACIS detector on board the Chandra X-ray Observatory. Due to its...
