A Near‐Infrared Spectral Template for Quasars
We present a near-infrared quasar composite spectrum spanning the wavelength range 0.58 - 3.5 um. The spectrum has been constructed from observations of 27 quasars obtained at t...

Combining radio observations with optical and infrared color selection--demonstrated in our pilot study to be an efficient selection algorithm for finding red quasars--we have o...
The Reddest Quasars
In a survey of quasar candidates selected by matching the FIRST and 2MASS catalogs, we have found two extraordinarily red quasars. FIRST J013435.7-093102 is a 1 Jy source at z=2...
ULTRACOOL FIELD BROWN DWARF CANDIDATES SELECTED AT 4.5 μm
We have identified a sample of cool field brown dwarf candidates using IRAC\ndata from the Spitzer Deep, Wide-Field Survey (SDWFS). The candidates were\nselected from 400,000 SD...
FIRST‐2Mass Sources below the APM Detection Threshold: A Population of Highly Reddened Quasars
We have constructed a sample of bright near-infrared sources which are detected at radio wavelengths but undetected on the POSS I plates in order to search for a population of d...
