We present preliminary results of line identification and equivalent width measurements in spectra of late M Dwarfs. We obtained 3.5 nights on Keck NASA time to collect high resolution (R 20,000) near-infrared (J-band) spectra using the NIRSPEC instrument on the Keck II telescope. Our sample consists of 40 nearby (distance 20 pc) late M dwarfs

On-going explorations of AGN based at mid-IR wavelengths has tightly constrained individual torus sizes to a few pc and found that spectral fitting in the N band window is consistent with toroidal obscuration at the center of AGN in a non-homogenous or `clumpy’ structure. We discuss results of two recent papers where we combine our mid-IR data with

Context. Knowledge of the total population of symbiotic stars in the Galaxy is important for understanding basic aspects of stellar evolution in interacting binaries and the relevance of this class of objects in the formation of supernovae of type Ia. Aims: In a previous paper, we presented the selection criteria needed to search for symbiotic

Recent studies by the Arkansas Galaxy Evolution Survey (AGES) collaboration have shown that there is a strong correlation between the pitch angles of field spiral galaxies and the mass of the galaxy's supermassive black holes (SMBHs). For this reason, we are interested in the consistency of measures of average pitch angle across galaxies in

We present the discovery of an L subdwarf in 234 deg2 common to the UK InfraRed Telescope (UKIRT) Infrared Deep Sky Survey Large Area Survey Data Release 2 and the Sloan Digital Sky Survey Data Release 3. This is the fifth L subdwarf announced to date, the first one identified in the UKIRT Infrared Deep Sky Survey, and the faintest known. The blue
