Bright Seyfert Nuclei: FTS spectroscopy

This proposal is to measure the full 200670um FTS spectra at high <br>resolution (virgul500 km/s) of 10 bright Seyfert nuclei. We are aiming to <br>detect the highJ CO lines, the [CI] and [NII] fine structure lines and <br>any other possible emission or absorption from H2O or other molecules. <br>The selected targets include four AGN1.s (two Seyfert 1.s and two <br>HBLRSeyfert 2.s), three AGN2.s and three lower nuclear activity objects. <br>These objects have been chosen because they are the brightest at 60100 <br>um and their IR luminosity has been separated between AGN and Starburst <br>components through midIR spectroscopy. This program is fully <br>complementary to the Hercules OTKP, which is focused on SPIRE FTS <br>spectroscopy of the ULIRG/LIRG population, while the present proposal targets<br>optically bright nuclei, at a presumably later evolutionary stage.<br>We expect that the detection of the CO ladder in Seyfert nuclei will allow <br>us to measure the effects of the AGN on the circumnuclear ISM of the galaxy <br>through detection of Xray dominated regions. Moreover the molecular <br>spectroscopy could reveal the presence of the predicted molecular tori.<br>The 10 galaxies for which we request SPIRE FTS observations of their nuclei <br>in one single position can be observed in a total integration time of 14.7 <br>hours. To complement the spectroscopic observations, photometric imaging with <br>SPIRE and PACS is also requested with a total time needed of 0.7 and 2.4 <br>hours, respectively.

本提案旨在测量10颗明亮塞佛特星核的完整200670微米远红外光栅光谱，以高分辨率（500 km/s）进行观测。我们旨在探测高J CO谱线、[CI]和[NII]精细结构谱线，以及来自H2O或其他分子的任何可能的发射或吸收光谱。所选目标包括四个AGN1.s（两个塞佛特1.s和两个高蓝移河外射电星系塞佛特2.s）、三个AGN2.s和三个较低核活动物体。这些天体之所以被选中，是因为它们在60100微米波段亮度最高，且通过中红外光谱已将它们的红外亮度区分于AGN和星暴成分。本计划与赫拉克勒斯OTKP完全互补，后者专注于对ULIRG/LIRG群体的SPIRE光栅光谱观测，而本提案则针对光学亮度较高的星核，预计处于更晚的演化阶段。我们期望通过探测塞佛特星核中的CO谱系，能够测量活动星系核对银河系核周ISM的影响，通过探测X射线主导区域。此外，分子光谱学可能揭示预言的分子环的存在。对于我们请求的SPIRE光栅对10个星核的单点观测，可在14.7小时的总积分时间内完成。为了补充光谱观测，我们还请求使用SPIRE和PACS进行光度成像，分别需要的总时间为0.7小时和2.4小时。[截断！请参阅实际数据以获取全文][截断！请参阅实际数据以获取全文]
