Are There Rotation Measure Gradients across Active Galactic Nuclei Jets?
We report on multi-frequency polarimetry very long baseline interferometry observations of active galactic nuclei using the Very Long Baseline Array. These observations are used to construct images of the Faraday rotation measure (RM) in J1613+342, Mrk 501, 3C 371, and BL Lac. Despite having resolved the jets in total intensity and polarization for three of these sources no RM gradients are fou...
متن کاملFaraday Rotation Measure Synthesis
We extend the rotation measure work of Burn (1966) to the cases of limited sampling of λ2 space and non-constant emission spectra. We introduce the rotation measure transfer function (RMTF), which is an excellent predictor of nπ ambiguity problems with the λ coverage. Rotation measure synthesis can be implemented very efficiently on modern computers. Because the analysis is easily applied to wi...

Title of dissertation: PROBING THE CENTRAL REGIONS OF ACTIVE GALACTIC NUCLEI Anne Maria Lohfink, Doctor of Philosophy, 2014 Dissertation directed by: Professor Christopher S. Reynolds Department of Astronomy Active Galactic Nuclei (AGN) are one of the key players in the Universe. Their energy output can strongly affect the growth of their host galaxy and can promote or suppress star formation o...
متن کاملGravitational Waves from Compact Objects Accreting onto Active Galactic Nuclei
We consider a model in which massive stars form in a self-gravitating accretion disk around an active galactic nucleus. These stars may evolve and collapse to form compact objects on a time scale shorter than the accretion time, thus producing an important family of sources for LISA. Assuming the compact object formation/inspiral rate is proportional to the steady-state gas accretion rate, we u...
متن کاملCharacteristics of the Galactic magneto-ionized ISM from Faraday rotation
Faraday rotation measurements of polarized extragalactic sources probe the Galactic magnetized, ionized interstellar medium. Rotation measures of these sources behind the inner Galactic plane are used to explore characteristics of the structure in the spiral arms and in interarm regions. Structure in the spiral arms has a characteristic outer scale of a few parsecs only, whereas interarm region...
