![]() The Caltech seal is not downloadable and may not be used as a graphic element. During the afternoon it is started up by a Laser Specialist. By default, 30 similar color tones are matched but you can change it as you see fit. To match similar color tones, enter the similarity percentage in the settings. For more information about how to use the seal, see Seal Usage Guidelines. Operation of the laser is totally transparent to the observer. This online browser program replaces any solid color and its close color tones in a Portable Network Graphics (PNG) photo or picture with transparent pixels. The seal should not be used for materials such as research posters, PowerPoints or business cards. Such instances include presidential communications, official transcripts, and letters of admission to Caltech. ![]() The Caltech seal is the official imprint of Caltech is reserved only for formal and ceremonial uses.

Parsec is a remote desktop youll actually love. This includes but is not restricted to substituting or changing the logo color or font, applying shadows, outlines, or surrounding boxes, and using the logo as a window for imagery. Utilize invoicing & POs, receive dedicated account support, a 99.9 uptime guarantee, and take advantage of a High Performance Relay server. It should never be re-created or typeset. Treat the logo as artwork, not as typography.The logo should be used to represent Caltech in all communications except the most formal, for which the seal is reserved. Our logo reflects the Institute's stature and reputation by emphasizing the Caltech name. Irongate is an intergalactic prison planet populated by a melting pot of the worst criminals the universe has to offer. The official name, "California Institute of Technology" should be used only in legal documents and formal uses, such as diplomas. The observed variety of polarized signatures can be explained by a model of spine-sheath jet structure."Caltech" is our preferred name and should be used in all references. At the same time jets themselves contain large-scale, ordered magnetic fields and tend to align its direction with the jet flow. Half of the sources show evidence for the helical magnetic fields in their rotating magnetoionic media. The magnetic field in the Faraday screen has no preferred orientation, and is observed to be random or regular from source to source. Significant transverse rotation measure gradients are observed in seven sources. The typical RM of transparent jet regions has values of an order of a hundred rad/m^2. ![]() ![]() The highest core RM reaches 16,900 rad/m^2 in the source rest frame for the quasar 0952+179, suggesting the presence of highly magnetized, dense media in these regions. The RM changes along the jets, systematically increasing its value towards synchrotron self-absorbed cores at shorter wavelengths. Wavelength-dependence of the fractional polarization and polarization angle is consistent with external Faraday rotation, while some sources show internal rotation. The study allowed us to investigate linearly polarized properties of the jets at parsec-scales: distribution of the Faraday rotation measure (RM) and fractional polarization along the jets, Faraday effects and structure of Faraday-corrected polarization images.
