Artillery Shells over Circinus
The recently identified Circinus Galaxy is the nearest (∼ 4 Mpc) Seyfert 2 galaxy known and we now demonstrate to be one of the best laboratories for studying the effects of nuclear activity3 on the surrounding environment. Here we present new imaging Fabry-Perot observations of Circinus which confirm the existence of an ionization cone in this object but also show for the first time a complex ...
متن کاملA Chandra Observation of the Circinus Galaxy
We report on a recent Chandra ACIS-S observation of the Circinus galaxy. These observations confirm that the nuclear spectrum results from reflection of a hard X-ray continuum by “neutral” matter. The nuclear X-ray emission is extended by ∼ 60 pc in the general direction of the optical “ionization cone”. An image in the Fe Kα line has been made and shows that this emission extends up to 200 pc ...
متن کاملImmunochemicalMeasurement of Lipoprotein-X1
Lipoprotein-X, an abnormal lipoprotein that is specific for cholestasis, was quantitated by immunochemical methods. Interfering lipoproteins also present in normal serum and sharing antigenic determinants with lipoprotein-X were removed before the sample was applied, by precipitation with purified anti-lipoprotein B or a 7-globulin fraction of specific lipoprotein B antiserum. On Laurell electr...
متن کاملA molecular ring in the Circinus galaxy ⋆
The Circinus galaxy, a type 2 Seyfert, is suspected to have a molecular gas ring structure with a diameter of ∼ 500 pc. We have mapped the lowest three rotational transitions of 12 CO in the central region of the galaxy, and upon detailed examination, the data suggest that a fraction of the molecular gas is orbiting the galaxy's nucleus in the form of a ring. There also appears to exist an asso...
متن کاملA molecular outflow in the Circinus galaxy ?
From previous work on the Circinus galaxy we postulated that ≈ 50% of the molecular gas in this type 2 Seyfert nucleus is distributed in a sub-kiloparsec circumnuclear ring, probably associated with the ongoing star-burst. In addition to this, we postulated the possible presence of a molecular outflow along the galaxy's minor axis. In this work we use a modified version of the routine used prev...
