14 Mar 2002 | Journal: | Mon.Not.Roy.Astron.Soc. 331 (2002) 284 | Subject: | astro-ph | Affiliation: | 1, 3), Jeremy Allington-Smith , Scott Chapman (2, 4), Robert Content , Christine Done , Roger Haynes (1, 5), David Lee (1, 6) and Simon Morris (2, 7) ( University of Durham, Herzberg Institute of Astrophysics Now at Gemini Observatory, Now at Calif | Abstract: | The centre of NGC 4151 has been observed in the J-band with the SMIRFS integral field unit (IFU) on the UK Infrared Telescope. A map of [Fe II] emission is derived, and compared with the distributions of the optical narrow line region and radio jet. We conclude that, because the [Fe II] emission is associated more closely with the visible narrow-line region than with the radio jet, it arises mainly through photoionization of gas by collimated X-rays from the Seyfert nucleus. The velocity field and strength with respect to [Pa B] are found to be consistent with this argument. The performance of the IFU is considered briefly, and techniques for observation and data analysis are discussed. | Source: | arXiv, astro-ph/0203236 | Services: | Forum | Review | PDF | Favorites |
