Diffuse Thermal Emission from Very Hot Gas in Starburst Galaxies
BeppoSAX observations of the nearby archetypical starburst galaxies NGC253 and M82 are presented. Spectral analysis shows that the 2–10 keV spectra of both galaxies, extracted from the central 4 regions, are best fitted by a thermal emission model with kT ∼ 6–9 keV and metal abundances ∼ 0.1–0.3 solar. The spatial analysis yields clear evidence that this emission is extended in NGC 253, and pos...
متن کاملHybrid Thermal-Nonthermal Synchrotron Emission from Hot Accretion Flows
We investigate the effect of a hybrid electron population, consisting of both thermal and non-thermal particles, on the synchrotron spectrum, image size, and image shape of a hot accretion flow onto a supermassive black hole. We find two universal features in the emitted synchrotron spectrum: (i) a prominent shoulder at low (∼< 10 11 Hz) frequencies that is weakly dependent on the shape of the ...
متن کاملNon-thermal Radio Emission from Single Hot Stars
Many O stars are observable at radio wavelengths, due to thermal emission from the ionized gas in the stellar wind. The emergent radio spectrum has a characteristic spectral index ∼ 0.6 (i.e., Fν ∝ λ ). However, about 25% of the brightest O stars have a radio spectrum that differs from the thermal radio emission (Bieging, Abbott, & Churchwell 1989). This non-thermal radio emission is believed t...
متن کاملTailoring self-assembled metallic photonic crystals for modified thermal emission.
We predict that modified thermal emission can result from three-dimensional, self-assembled photonic crystals. In previous tungsten structures, known as inverse opals, strong absorption prevented any influence of the periodicity. We consider the origin of this effect and show how to tailor both absorption and surface coupling in experimentally realizable metallic inverse opals. Calculations for...
متن کاملThermal Emission from Transiting Very-Hot Jupiters: Prospects for Ground-based Detection at Optical Wavelengths
Very hot Jupiters (VHJs) are defined as Jupiter-mass extrasolar planets with orbital periods shorter than three days. For low albedos the effective temperatures of irradiated VHJs can reach 2500–3000 K. Thermal emission from VHJs is therefore potentially strong at optical wavelengths. We explore the prospects of detecting optical-wavelength thermal emission during secondary eclipse with existin...
