Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...

... We present the results of recent pulsar observations at frequencies between 27.9 GHz and 34.8 GHz, i.e. in a wavelength range of 10.75 mm to 8.61 mm, made with the Effelsberg radiotelescope. The measured flux densities of two out of nine detected pulsars suggest that the spectrum flattens at high frequencies or even shows a turn-over. ... In this work we will only focus on pulsar spectra. ... Figure 4: Derived spectra of the second strongest pulsar observed at mm-wavelengths. ...

When combined with infrared observations with the Spitzer telescope (3 to 160 ЮМm), the Herschel Space Observatory now fully samples the thermal dust emission up to 500 ЮМm and enables us to better estimate the total infrared-submm energy budget (LTIR) of nearby galaxies. We present new empirical calibrations to estimate resolved and integrated total infrared luminosities from Spitzer and Herschel bands used as monochromatic or combined tracers. ...
