Spatially Resolved Circumnuclear Dust in Centaurus A
Margarita Karovska,Massimo Marengo,Martin Elvis,Giovanni G. Fazio,Joseph L. Hora,Philip M. Hinz,William F. Hoffmann,Michael R. Meyer,Eric E. Mamajek +8 more
TL;DR: In this article, the Magellan 6.5 m telescope with the MIRAC/BLINC camera has been used to detect mid-IR emission from a compact region surrounding the active galactic nucleus (AGN).
Proceedings ArticleDOI
SIRTF-CTA optical performance test results
John P. Schwenker,Bernhard R. Brandl,William F. Hoffmann,Joseph L. Hora,Amy Mainzer,John Eric Mentzell,Jeff Van Cleve +6 more
TL;DR: In this paper, the principal optical results of the "End to End" test conducted on the SIRTF Cryogenic Telescope Assembly were described. But the results were not used to evaluate the performance of the entire assembly.
Journal ArticleDOI
Infrared lightcurves of near earth objects
Joseph L. Hora,Amir Siraj,Michael Mommert,Michael Mommert,Andrew McNeill,David Trilling,Annika Gustafsson,Howard A. Smith,Giovanni G. Fazio,Steven R. Chesley,Joshua P. Emery,Alan W. Harris,Michael Mueller,Michael Mueller +13 more
TL;DR: In this article, the authors present lightcurves and derive periods and amplitudes for a subset of 38 near earth objects (NEOs) observed at 4.5 microns with the IRAC camera on the Spitzer Space Telescope, many of them having no previously reported rotation periods.

TL;DR: In this paper, the authors describe several exciting new research directions that, over the next 10 years, hold the potential to answer some of the biggest scientific questions raised in recent decades: Is General Relativity the correct description for supermassive black holes? What is the nature of star formation in extreme environments? How do stars and compact objects dynamically interact with the supermassive Black Hole? What physical processes drive gas accretion in low-luminosity black hole?
Proceedings ArticleDOI
First results of nulling interferometry with the Multiple-Mirror Telescope
Philip M. Hinz,James Roger P. Angel,William F. Hoffmann,Donald W. McCarthy,Patrick C. McGuire,Matthew Cheselka,Joseph L. Hora,Neville J. Woolf +7 more
TL;DR: In this paper, the authors used nulling interferometry at 10 μm wavelength to interferometrically suppress a star's radiation, which is used to search for Earth-like extra-solar planets and their spectroscopic signatures of habitability and life.
