Thermal and Nonthermal Emission from the Nearby Galaxy M33
A multi-wavelength study of radio and IR emission from the nearby galaxy M33 is presented. We focus on three main topics: 1) energy sources of IR emission and its correlation with radio continuum emission at different spatial scales, 2) separation of thermal and nonthermal components of the radio continuum emission without assuming a constant nonthermal spectral index, and 3) distribution of th...
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 کاملThermal and Non - Thermal Infrared Emission from M 87
We discuss images of M87 from 3.6 to 160 μm obtained with Spitzer. As found previously, there is an excess in the far infrared over a simple power law interpolation from the radio to the resolved nonthermal features in the mid-infrared and optical. We show that this excess is most likely warm dust in the galaxy itself, and that the properties of this emission component are similar to the far in...
متن کاملThermal infrared emission from biased graphene.
The high carrier mobility and thermal conductivity of graphene make it a candidate material for future high-speed electronic devices. Although the thermal behaviour of high-speed devices can limit their performance, the thermal properties of graphene devices remain incompletely understood. Here, we show that spatially resolved thermal radiation from biased graphene transistors can be used to ex...
متن کاملThermal and Nonthermal X-ray Emission from the Forward Shock in Tycho’s Supernova Remnant
We present Chandra X-ray images of Tycho’s supernova remnant that delineate its outer shock as a thin, smooth rim along the straight northeastern edge and most of the circular western half. The images also show that the Si and S ejecta are highly clumpy, and have reached near the forward shock at numerous locations. Most of the X-ray spectra that we examine along the rim show evidence of line e...
