The study of diffuse light spectroscopy and imaging in tissue continues to provide new insight into the structural and functional properties of tissues that are not easily accessed by alternative meth...
Chemistry,Temperature,and Faunal Distributions at Diffuse-Flow Hydrothermal Vents:Comparison of Two Geologically Distinct Ridge Systems

Black smokers are the dramatic result of seawater being heated to high temperatures (generally 250° to 350°C) by magmatic systems, then discharging at the seafloor. However, not all seawater that circ...
Extra-planar Diffuse Hot Gas Around Normal Disk Galaxies
Hot Gas Galaxies

2014/12/24
I review results from Chandra observations of nearby normal edge-on galaxies (Sd to Sa types). These galaxies have a broad range of star formation rate, but none of them is dominated by a nuclear star...
Diffuse X-Rays from the Arches and Quintuplet Clusters
thermal shock waves
font style='font-size:12px;'>
2014/12/24
The origin and initial mass function of young stellar clusters near the Galactic center are still poorly understood. Two of the more prominent ones, the Arches and Quintuplet clusters, may have formed...
The Nonisothermality and Extent of Galactic Diffuse Hot Gas toward Markarian 421
ISM Mrk 421
font style='font-size:12px;'>
2014/12/23
Diffuse hot gas can be traced effectively by its X-ray absorption and emission. We present a joint analysis of these tracers to characterize the spatial and temperature distributions of the Galactic h...
The Galactic Central Diffuse X-Ray Enhancement: A Differential Absorption/Emission Analysis
3C 273 Mrk 421
font style='font-size:12px;'>
2014/12/23
The soft X-ray background shows a general enhancement toward the inner region of the Galaxy. But whether this enhancement is a local feature (e.g., a superbubble within a distance of 200 pc) and/or a ...
Chandra and XMM–Newton detection of large-scale diffuse X-ray emission from the Sombrero galaxy
Sombrero NGC 4594
font style='font-size:12px;'>
2014/12/23
We present an X-ray study of the massive edge-on Sa galaxy, Sombrero (M 104; NGC 4594), based on XMM–Newton and Chandra observations. A list of 62 XMM–Newton and 175 Chandra discrete X-ray sources is ...
Chandra Detection of Diffuse Hot Gas in and around the M31 Bulge
spiral general
font style='font-size:12px;'>
2014/12/23
We report the detection of diffuse hot gas in M31, using archival Chandra observations that allow us to map out a 30' × 30' field (covering a galactocentric radius up to 4.5 kpc) and to detect sources...

X-RAY AND ULTRAVIOLET SPECTROSCOPY OF GALACTIC DIFFUSE HOT GAS ALONG THE LARGE MAGELLANIC CLOUD X-3 SIGHT LINE
diffuse background halo
font style='font-size:12px;'>
2014/12/23
We present Suzaku spectra of X-ray emission in the fields just off the LMC X-3 sight line. O VII, O VIII, and Ne IX emission lines are clearly detected, suggesting the presence of an optically thin th...
DETECTION OF DIFFUSE NEUTRAL INTRAGROUP MEDIUM IN HICKSON COMPACT GROUPS

2014/12/20
We present new Green Bank Telescope (GBT) 21 cm neutral hydrogen (H I) observations of a complete distance-limited sample of 22 Hickson Compact Groups (HCGs) with at least four true members. We detect...
A simple parameterization of the short-wave aerosol optical properties for surface direct and diffuse irradiances assessment in a numerical weather model

Broadband short-wave (SW) surface direct and
diffuse irradiances are not typically within the set of output
variables produced by numerical weather prediction (NWP)
models. However, they are freque...
