Introduction: Multiphoton fluorescence excitation microscopy (MPM) is an invaluable tool for studying processes in tissue in live animals by enabling biologists to view tissues up to hundreds of micro...
Nuclear de-excitation line spectrum of Cassiopeia A
Astroparticle physics – cosmic rays – ISM: supernova remnants
2011/10/13
The supernova remnant Cassiopeia A is a prime candidate for accelerating cosmic ray protons and ions. Gamma rays have been observed at GeV and TeV energies, which indicates hadronic interactions, but ...
Excitation of the aromatic infrared emission bands: Chemical energy in hydrogenated amorphous carbon particles?
Excitation aromatic infrared emission bands: Chemical energy
2011/10/11
We outline a model for the heating of hydrogenated amorphous (HAC) dust via the release of stored chemical energy and show that this energy (~12 kJ/mole) is sufficient to heat dust grains of classical...

The composition of the space radiation environment inside spacecrafts is modified by the interaction with shielding material, with equipment and even with the astronauts' bodies. Accurate quantitativ...
Dense Molecular Gas Excitation at High Redshift: Detection of HCO+(J=4-3) Emission in the Cloverleaf Quasar
galaxies active — galaxies starburst — galaxies formation — galaxies
2010/11/10
We report the detection of HCO+(J=4→3) emission in the Cloverleaf Quasar at z=2.56, using
the IRAM Plateau de Bure Interferometer. HCO+ emission is a star formation indicator similar
to HCN, tracing...
Dense Molecular Gas Excitation in Nuclear Starbursts at High Redshift: HCN, HNC, and HCO+(J=6-5) Emission in the z=3.91 Quasar Host of APM08279+5255
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
We report the detection of surprisingly strong HCN, HNC, and HCO+(J=6-5) emission in the host galaxy of the z=3.91 quasar APM08279+5255 through observations with CARMA. HCN, HNC, and HCO+ are typicall...
The rotational excitation of HCN and HNC by He: New insights on the HCN/HNC abundance ratio in molecular clouds
Molecular data Molecular processes scattering
2010/3/9
Modeling of molecular emission from interstellar clouds requires the calculation of rates for excitation by collisions with the most abundant species. The present paper focuses on the calculation of r...

Excitation of Solar-like Oscillations：From PMS to MS Stellar Models
Turbulence convection oscillations excitation sun stars:α Cen A—stars:main and pre-main sequence stars
2009/5/12
The amplitude of solar-like oscillations results from a balance
between excitation and damping. As in the sun, the excitation is attributed
to turbulent motions that stochastically excite the p mode...
