... This is likely to be associated with shadowing effects whereby the islands which are formed early in the coating pro cess cast an effective shadow over adjacent regions, resulting in coating voids and lower overall density. ...
... In low Galactic latitude (jbj < 30 ) directions no shadows were seen, except for a shadow in the C band towards an enhancement associated with Loop I or the Galactic bulge and it is not \representative of the general di use background." ...
... Flare intervals thus identified were removed from the data as were events with chipy=1:8, which corresponds to an area on each ACIS chip that is shadowed by the frame store cover and not exposed to sky emission. ...

... Instead they favor a model based on a geometric effect intrinsic to the quasar such as shadowing of the NLR by a coplanar, toroidalshaped BLR so that the covering factor, perhaps determined by the ratio of accretion rate to the Eddington rate, drives ...
... strength of background O emission have been noted (tentatively) in repeated Chandra observations of MBM 12, a nearby dark molecular cloud that shadows much of the SXRB (R. J. Edgar et al. 2004, in preparation), and in XMM-Newton observations of the Hubble ...
... The shadows cast on the gas by spiral arms and the 10-kp c star-forming ring confirm large off-plane extent of the gas. (iii) Hard unresolved emission from spiral arms, most likely asso ciated with protostars and young stellar ob jects located in the star ...
