We report the discovery with the Atacama Pathfinder EXperiment ( APEX ) of an outflow of molecular gas in the radio-loud Seyfert galaxy ICÂ 5063 ( z = 0.0110 ) .
In addition to the emission of the large-scale CO disk , a prominent blueshifted wing is observed in the CO ( 2-1 ) spectrum .
ICÂ 5063 represents one of the best cases of a fast jet-driven H I Â ( and ionized gas ) outflow , which is located at the site of a radio-bright feature about 0.5 kpc from the nucleus .
It is possible that the blueshifted part of the molecular gas is associated with this outflow and is accelerated by the interaction with the radio jet .
The outflow of molecular gas is characterized by an H _ { 2 } mass of the outflowing component of between 2.25 \pm 0.70 \times 10 ^ { 7 } { M } _ { \odot } Â and 1.29 \pm 0.40 \times 10 ^ { 8 } { M } _ { \odot } Â and a mass outflow rate between 22 and 129 { M } _ { \odot } yr ^ { -1 } Â depending on the assumption for \alpha _ { X } and assuming a luminosity ratio L ^ { \prime } CO ( 2-1 ) /L ^ { \prime } CO ( 1-0 ) = 1 .
This confirms that this may indeed be the dominant component in outflows driven by the nuclear activity that are also found in other objects .
However , this high mass outflow rate can not easily be supported for a long time , suggesting that the gas outflow in ICÂ 5063 happens in bursts and is in a particularly strong phase at present .
Owing to its proximity , ICÂ 5063 serves as an excellent laboratory for understanding the impact of radio jets on the gas-rich inter-stellar medium .
