Title: NIR spectroscopy of Palomar AGN
Abstract:
We propose to continue our infrared investigation of Palomar AGN with GNIRS
cross- dispersed spectroscopy of a further 27 Seyferts and LINERs. The
spectra will advance our knowledge of AGN physics and lifecycles by
demonstrating whether the accretion disk and nuclear dust properties change
as a function of accretion rate, as predicted by theoretical models. They
will be used to investigate the mechanisms powering the emission lines, with
implications for AGN demographics, and to assess the contribution of AGB
stars and late-type dwarfs to the NIR light. The number and variety of
spectral features that will appear in the data are expected to enable a wide
range of science besides that highlighted in this proposal. For this reason,
we plan to quickly make the reduced spectra available to the community (see
technical section). We anticipate applying for time to observe the remaining
AGN in the (near-complete) Palomar sample over the next few semesters. The
targets are distributed throughout the northern sky, making Gemini's queue
mode ideal for this work. The fairly short observations are easily scheduled
and can be carried out in suboptimal observing conditions.
