    In this catalogue compact sources are detected outside the adopted Planck GAL mask; thus, these sources constitute a highly reliable sample of extragalactic radio sources. This book began as a set of lecture notes for a junior/senior course entitled \Observatory Meth-ods" that I teach each spring at the University of Oklahoma (OU). The book is intended as an introduction for the college astrophysics major to photometry in the optical region of the spectrumFile Size: 1MB.

    This book began as a set of lecture notes for a junior/senior course entitled \Observatory Meth-ods" that I teach each spring at the University of Oklahoma (OU). The book is intended as an introduction for the college astrophysics major to photometry in the optical region of the spectrum. Photometry, from Greek photo- and -metry, is a technique used in astronomy that is concerned with measuring the flux or intensity of light radiated by astronomical objects. This light is measured through a telescope using a photometer, often made using electronic devices such as a CCD photometer or a photoelectric photometer that converts light into an electric current by the photoelectric effect. .

Get this from a library. Far-infrared photometry of compact extragalactic sources: OJ and BL Lac. [Paul M Harvey; Ames Research Center.;]. These first measurements of two BL Lac objects in the far-infrared show them to be similar to the few quasars previously observed in the far-infrared. In particular, there is no evidence for significant dust emission, and the lambda approximately micron flux density fits on a smooth line joining the near-infrared and millimeter continuum fluxes.

The 50 and micron emissions of OJ were detected and upper limits for BL Lac were obtained. These first measurements of two BL Lac objects in the far-infrared show them to be similar to the few quasars previously observed in the far-infrared.

In particular, there is no evidence for significant dust emission, and the lambda approximately micron flux density fits on a smooth line. The observed flux density of + or - Jy at microns and an upper limit of + or - Jy at 50 microns clearly define the overall energy distribution and.

We present a new catalogue of ALMA observations of 3, bright, compact radio sources, mostly blazars, used as calibrators.

These sources were observed between May and Julyfor a total of 47, pointings in different bands and epochs. We have exploited the ALMA data to validate the photometry given in the new Planck Multi-frequency Catalogue of Non-thermal sources (PCNT), for Cited by: 4.

We h observations of 3, di erent sources in band 3 (84 GHz), observations of IRAS observations of extragalactic objects are analyzed, supplemented by optical spectroscopy and 10 μm photometry. The relationship between various forms of activity in the nuclei of spiral galaxies and their mid- to far-infrared spectral energy distributions is explored.
