Journal ArticleDOI
Ultraluminous infrared galaxies and the origin of quasars
David B. Sanders,B. T. Soifer,J. H. Elias,Barry F. Madore,Keith Matthews,G. Neugebauer,Nick Scoville +6 more
TL;DR: In this article, ground-based observations of a complete sample of 10 of these infrared galaxies suggest that they represent the initial dust-enshrouded stages of quasars, and a second group of ultraluminous objects selected on the basis of warm infrared colors are found to be preferentially Seyfert galaxies.
Journal ArticleDOI
The Infrared Astronomical Satellite (IRAS) mission
G. Neugebauer,H. J. Habing,R. J. van Duinen,H. H. Aumann,B. Baud,Charles Beichman,D. A. Beintema,N. Boggess,P. E. Clegg,T. de Jong,J. P. Emerson,T. N. Gautier,F. C. Gillett,S. Harris,M. G. Hauser,J. R. Houck,R. E. Jennings,F. J. Low,P. L. Marsden,George K. Miley,F. M. Olnon,Stuart Pottasch,E. Raimond,M. Rowan-Robinson,B. T. Soifer,Russell G. Walker,P. R. Wesselius,Erick T. Young +27 more
TL;DR: The Infrared Astronomical Satellite (IRAS) as discussed by the authors consists of a spacecraft and a liquid helium cryostat that contains a cooled IR telescope, whose focal plane assembly is cooled to less than 3 K, and contains 62 IR detectors in the survey array.
Journal ArticleDOI
The First Measurement of Spectral Lines in a Short-Period Star Bound to the Galaxy’s Central Black Hole: A Paradox of Youth
Andrea M. Ghez,Andrea M. Ghez,Gaspard Duchêne,Keith Matthews,Seth D. Hornstein,Angelle Tanner,James E. Larkin,Mark Morris,Eric E. Becklin,Samir Salim,T. Kremenek,T. Kremenek,David R. Thompson,B. T. Soifer,G. Neugebauer,G. Neugebauer,Ian S. McLean +16 more
TL;DR: In this paper, the spectral absorption lines in one of the high-velocity stars in the vicinity of the Galaxy's central supermassive black hole have been detected, indicating that the star is behind the black hole at the time of closest approach and countervolving against the Galaxy.
Journal ArticleDOI
Continuum energy distribution of quasars: Shapes and origins
TL;DR: In this article, the authors show that most of the bright quasars from the Palomar-Green (PG) survey appear to emit the bulk of their luminosity (typically more than 90%) between 3 nm and 300 μm (10.7-10^(18) Hz).
Journal ArticleDOI
Discovery of a shell around alpha-lyrae
H. H. Aumann,F. C. Gillett,Ca Beichman,T Dejong,[No Value] Houck,F. J. Low,G. Neugebauer,R. L. Walker,P. R. Wesselius +8 more
TL;DR: The first detection of a large infrared excess from a main-sequence star without significant mass loss was reported in this article. But this was only for the case of Alpha Lyrae, which has a diameter of about 20 arcsec.
