The Search for Technosignatures: a Review of Possibilities
Clément Vidal, Benji L. Fields, Damian R. Sowinski +19
This paper reviews the diverse range of technosignatures that have been proposed in the literature. We organize the review by spatial scales from the Earth and the solar system to…
The Photo-z Infrared Telescope (PIRT) -- a space instrument for rapid follow up of high-redshift gamma-ray bursts and electromagnetic counterparts to gravitational wave events
M. Seiffert, A. Balady, T. -C. Chang +17
The Photo-z InfraRed Telescope (PIRT) is an instrument on the Gamow Explorer, currently proposed for a NASA Astrophysics Medium Explorer. PIRT works in tandem with a companion wide…
An Infrared Coronagraphic Survey for Substellar Companions
P. Lowrance, E. E. Becklin, G. Schneider +10
We have used the F160W filter (1.4-1.8 um) and the coronagraph on the Near-InfraRed Camera and Multi-Object Spectrometer (NICMOS) on the Hubble Space Telescope (HST) to survey 45 s…
A Candidate Substellar Companion to HR 7329
P. J. Lowrance, G. Schneider, J. D. Kirkpatrick +10
We present the discovery of a candidate substellar companion from a survey of nearby, young stars with the NICMOS coronagraph on the Hubble Space Telescope. The H ~ 12 mag object w…
The Circumstellar Disk of HD 141569 Imaged with NICMOS
A. J. Weinberger, E. E. Becklin, G. Schneider +5
Coronagraphic imaging with the Near Infrared Camera and Multi Object Spectrometer on the Hubble Space Telescope reveals a large, ~400 AU (4'') radius, circumstellar disk around the…
NICMOS Imaging of the HR 4796A Circumstellar Disk
Glenn Schneider, Bradford A. Smith, E. E. Becklin +7
We report the first near infrared (NIR) imaging of a circumstellar annular disk around the young (~8 Myr), Vega-like star, HR 4796A. NICMOS coronagraph observations at 1.1 and 1.6…
A Candidate Substellar Companion to CoD -33 7795 (TWA 5)
P. J. Lowrance, C. McCarthy, E. E. Becklin +12
We present the discovery of a candidate substellar object in a survey of young stars in the solar vicinity using the sensitivity and spatial resolution afforded by the NICMOS coron…
The Environment of Lyman a Absorbers in the Sightline toward 3C273
S. L. Morris, R. J. Weymann, Alan Dressler +5
We present new ground-based data following up on the HST discovery of low-redshift Lya absorption in the sight-line to the quasar 3C273. Narrow-band filter observations show that t…
