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) ...
A SPITZER VIEW OF STAR FORMATION IN THE CYGNUS X NORTH COMPLEX

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...
