A program to search for luminosity evolution of giant elliptical galaxies at high redshift has been begun at 2.2μm. Observing at infrared wavelengths offers the possibility of avoiding large and uncertain K corrections at redshifts near 1. First res

The interstellar reddening law in the Taurus dark clouds is investigated from visual, infrared, and ground based ultraviolet photometric observations of heavily reddened stars HD 29647, HDE 283701, and HDE 283812. The star HD 29647 located in the cen

From infrared observation of a radio selected sample of QSOs, it is shown that optical identification programs produce samples biased against very red sources, even if identifications are made without regard to color.

It is unlikely that the optical‐infrared energetics of the Galactic Center are dominated by a single, nonthermal source as would be the case for a Seyfert or other kind of active galaxy. The energetics of this region can, however, be explained as t

Past studies have indicated that the stellar population at the Galactic Center includes a relatively young component with Source 7 being perhaps no older than 40 million years1. The extent of the young population could not be easily judged on the bas

We have investigated the continuum properties of the superluminal quasar 3C 345 with monitoring studies at radio, optical, infrared, and X-ray frequencies as well as with simultaneous multifrequency spectra extending from the radio through the X-ray
