... 739C As one part of a program to detect complete samples of active extragalactic objects, the 3.36x10^-3 sr field centered on alpha=12h04min, delta=+11deg30' (1950.0) was mapped with the Very Large Array at 1411MHz. Sixty-seven maps cover this field so that no point is more than 15arcmin from the nearest map center. ... The rms map noise is 0.030 + 0.001 mJy, and the resulting source list is complete to a map peak flux density S_p = 0.2 mJy within 25 arcmin of the field center. ...

22. Continent-sized radio telescope takes close-ups of Fermi active galaxies |
... Continent-sized radio telescope takes close-ups of Fermi active galaxies . Observations solidify a theory about radio-emitting jets emanating from supermassive black holes at the centers of active galaxies. ... The study solidifies the link between an active galaxy's gamma-ray emissions and its powerful radio-emitting jets. ... All this points to the team's conclusion that the portion of an active galaxy's radio jet closest to the galaxy's core is also the source of the gamma-rays Fermi detects. ...

23. Relations
... Mindful of these biases, I can now explore the relations between the measured rotation periods and various other observables. The hypothesis behind monitoring stellar variability is that active stars have asymmetric spot distributions on their photospheres. ... They found that only stars with rotation periods greater than seven days show variations greater than 0.4 magnitudes at I.

... They had expected to see impact craters like those on the other terrestrial bodies and from their number per unit area to estimate the age of Io's surface. ... This may have been the most important single discovery of the Voyager missions; it was the first real proof that the interiors of other "terrestrial" bodies are actually hot and active. ... A nalysis of the Voyager images led scienties to believe that the lava flows on Io's surface were composed mostly of various compounds of molten sulfur. ...

25. astro-ph
... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....
