Superluminal variations in 3C 120, 3C 273, and 3C 345
The Astrophysical Journal, 1979 The superluminal behavior of 3C 120, 3C 273, and 3C 345 has been reexamined in light of new hybrid maps of these objects. The maps of 3C 273 and 3C 345 are consistent with superluminal expansion. 3C 120 appeared to expand superluminally from 1972.6 to 1974.5, but the evidence has been inconclusive since 1974.5.

Spatially resolved spectra of 3C galaxy nuclei [PDF]
, 1998 We present and discuss visible-wavelength long-slit spectra of four low redshift 3C galaxies obtained with the STIS instrument on the Hubble Space Telescope. The slit was aligned with near-nuclear jet-like structure seen in HST images of the galaxies, to

Spectrophotometry of 3C 232 and 3C 249.1 [PDF]
Symposium - International Astronomical Union, 1986 We find indication of variability of the ratio Mg II 2934/2798 for 3C 232 and discuss the excitation mechanism of Mg II 2934. For 3C 249.1 we identified the following new lines: [Ne V] 3346, [Ne V) 3426 and He I 3884. Comments are made on continuum shapes; in both cases optical continuum variability is confirmed.

Feline infectious peritonitis: role of the feline coronavirus 3c gene in intestinal tropism and pathogenicity based upon isolates from resident and adopted shelter cats. [PDF]
, 2012 Feline infectious peritonitis virus (FIPV) was presumed to arise from mutations in the 3c of a ubiquitous and largely nonpathogenic feline enteric coronavirus (FECV).

Multifrequency Observations of the Virgo Blazars 3C 273 and 3C 279 in CGRO Cycle 8 [PDF]
, 2000 We report first observational results of multifrequency campaigns on the prominent Virgo blazars 3C 273 and 3C 279 which were carried out in January and February 1999. Both blazars are detected from radio to gamma-ray energies. We present the measured X-

A Spectral Analysis of 3C 67 and 3C 190 [PDF]
International Astronomical Union Colloquium, 1998 AbstractUsing new high resolution VLA and VLBA data and existing MERLIN data of 3C 67 and 3C 190, we find both sources have a complex spectral structure similar to larger Fanaroff-Riley type II sources. Our analysis of 3C 190 predicts either an unusually steep injection index of −0.8 and a young age, or a superposition of different age spectral ...

Cell Reports, 2015 Spontaneous tumor-initiated T cell priming is dependent on IFN-β production by tumor-resident dendritic cells. On the basis of recent observations indicating that IFN-β expression was dependent upon activation of the host STING pathway, we hypothesized ...
