Extragalactic Background Light and Gamma-Ray Attenuation
Luminosity density, galaxy spectral energy evolution, extragalactic background light, semi-analytic models of the evolving galaxy population, gamma ray attenuation
2011/10/8
Data from (non-) attenuation of gamma rays from active galactic nuclei (AGN) and gamma ray bursts (GRBs) give upper limits on the extragalactic background light (EBL) from the UV to the mid-IR that ar...
GOODS-Herschel Measurements of the Dust Attenuation of Typical Star-Forming Galaxies at High Redshift: Observations of UV-Selected Galaxies at z~2
Dust Attenuation Typical Star-Forming Galaxies High Redshift: Observations Galaxies
2011/10/9
We take advantage of the sensitivity and resolution of Herschel at 100 and 160 micron to directly image the thermal dust emission and investigate the infrared luminosities, L(IR), and dust obscuration...
Ross Ice Shelf in situ radio-frequency ice attenuation
Ross Ice Shelf situ radio-frequency ice attenuation
2010/11/10
We have measured the in situ average electric field attenuation length hL i for radio frequency signals broadcast vertically through the Ross Ice Shelf. We chose a location,Moore Embayment, south of M...
ATTENUATION LAW FOR GALAXIES WITH DIFFERENT STAR FORMATION HISTORIES, BASED ON THE SDSS IMAGES
Galaxies: photometry Galaxies: ISM Galaxies: stellar content
2010/10/29
Attenuation curves (laws) in the optical part of the spectrum (from about 3500 ºA to 9000 ºA) are determined for galaxies with di®erent star formation histories (SFHs) using images in &m...
